Arguing with Automatons

Introduction

There is no metaphysical middle ground between libertarian free will and automatonism. I stress the metaphysical here because there is phenomenological (psychological) middle ground that backs up into the epistemological. By “phenomenological middle ground” I refer to what I take to be most people’s every day experience with making choices. If you step into a taqueria and for a moment do not know if you “feel more like” chicken, beef, or pork, you think about it and choose one. We each make these (and many other) sorts of decisions throughout our day. In this process I (for I can in the end only speak for me) do not feel impelled by something, some combination of events in my past, to make one particular choice over another. I had chicken last week, so this week I’ll take the steak, or perhaps I liked the chicken so much I choose it again. Whether you are committed to libertarian free will philosophically the choice of chicken, steak, or pork, feels at least superficially free. Whichever choice you make you are at the same time aware that other choices (and so futures) were potentially open to you.

I will not further address this experience of phenomenological freedom because it is conceivable that you can genuinely believe you are free without actually being free just as genuinely believing you are Napoleon reincarnated does not mean you are Napoleon reincarnated. The issue then is not whether the alternatives appear open to you but whether they actually are open. Although you might have chosen beef or pork and have done so in the past, on this occasion something stemming from your past (indeed going all the way back to the big bang) determined that you would choose chicken and this determination was (usually is because otherwise the phenomenological room would also disappear) at least entirely subconscious if not in fact unconscious. On this occasion you were going to choose chicken just as on prior occasions there were determinations that led to your choosing steak or pork at those times. Automatons are entities that sometimes appear to make free decisions from a purely behavioral viewpoint, but which we know not to be free because we understand all of what leads deterministically to those choices; that is, we know all of what underlies the behavior both necessarily and sufficiently.

In this paper my goal is not to defend a view of libertarian free will as I have done that before here in this blog and other places. What does interest me here are two related things. First does it make any sense for a human being with free will to argue or debate with an entity who appears to be a human being but lacks free will? Second, if no human beings have free will does any debate or argument between such entities have any meaning or significance? I am thinking of the following scenario. Two human beings are having a debate. The thought of the first being is freely expressed through speech in a language that both know. That speech, having some meaning in the common language the other being grasps in her thought, leads to a free decision in the thought of the second being to accept the argument of the first being or to reject it and freely offer a counterargument of her own. Note the freedom involved here would entail the second being might have, besides agreeing or offering a counterargument, instead have chosen simply to be quiet and abandon the discussion among other options. What is crucial to meaning here is the respondent understands the semantic relation between the argument presented and her response whatever that turns out to be. “The semantic” is important here because the relation is not about the brain states of one party invoking brain states in the other, but rather subjective states of consciousness whose form and content do not resemble brain states.

The Argument

An automaton is a “state machine”. Some combination of parts each having various but finite numbers of states in which they can reside together determine what the automaton “does” at any given moment. The parts here can be mechanical, electromechanical, or of any other constitution that can express a “state”. Automatons today range from such trivial devices as automated floor cleaners to sophisticated computers in which software initially constrains possible “states” expressed in hardware; servomotors controlling a driver-less car or making chess moves on a game board. Every automaton begins in some first state when it is “turned on” and that state evolves in time from that point depending on what the automaton experiences in its inputs. Inputs include what it senses of the world’s response to its outputs (for example a chess move) which become further inputs. Not only do modern automatons “adapt” their behavior (within the range of mechanical possibility) by responding to their various inputs (given the potentials embedded in their programming), and that behavior can appear unexpected from the viewpoint of a human observer.

That these behaviors appear unexpected does not mean they are not fully determined (causally) by the automaton’s present state including all present inputs. In all the automatons we build from thermostats to self-driving cars and game playing computers we take this “ultimately determined” status for granted. We know that if we examine the machine’s workings in fine enough detail we will find exactly which combinations of states determined any particular behavior, that those states were sufficient to cause the behavior in question, and that those states were recursively determined by prior states (plus inputs) back in time to the machine’s first state. Because we know exactly how one state causes another we assume there is nothing more to the behavior of the automaton than its history of prior states. We assume that is, the automaton experiences no internal subjectivity. If two such automatons were to have an argument of some sort, a third-party would see what looked like our argument response between two humans illustrated above. But we have good reasons to believe that despite the behavioral similarity there is no subjective, semantic, understanding occurring in either of them.

Back in the 1970s there was an automaton named ELIZA. Today there are far more sophisticated automatons, but ELIZA is illustrative for my purposes here because it was specifically designed not so much to “be intelligent” but to mimic intelligence passing the Turing test. Simply stated, the Turing test proposed that a machine would or could be taken to be intelligent if in interacting with a human being, the human could not tell if it was interacting with a machine or another human. But the Turing test proved a little easy to pass under domain restricted circumstances and ELIZA was proof of that.

ELIZA’s domain was psychotherapy of the lite sort in which a therapist speaks one-to-one with a patient. Humans (students) were the patients and asked to talk (type) to their therapist.

Patient: I’m not sleeping well lately.
ELIZA: Have you any idea why?
Patient: I’m having bad dreams.
ELIZA: What are the dreams about?
Patient: My mother.
ELIZA: Tell me about your mother.

A simple program by today’s standards ELIZA found subjects, verbs, and objects in patient sentences and wove questions around one or more of them. If the program could not find any specific word to incorporate in its reply it output something more general like “why?” Most patients could tell that ELIZA was a machine but only after enough interaction that they realized ELIZA’s answers weren’t getting at anything. But initially, and in brief transactions, many patients thought they were speaking (typing) to a human being. But here’s where it gets really interesting for this argument. There came a point in work with ELIZA that some students, even knowing that ELIZA was a machine, not only continued to interact with it (some for long sessions), but reported experiencing therapeutic value! Some students said the sessions reduced stress and helped them think about their lives. The sessions “had meaning” in the broad sense, they had significance to the student.

The first question we want to ask is: were these interactions of meaning or significance to ELIZA? We assume not. We normally take it there is “nothing it is like” to be ELIZA, there is no consciousness there, no free will, no subjectivity. All of ELIZA’s replies are necessarily and sufficiently determined by a few hundred lines of code controlling the CPU and memory registers of a non-conscious automaton. One alternative view (taken by Chalmers and others) is there is something minimally “to be like” ELIZA, there is some subjectivity there though we cannot, from the human viewpoint “get at” what it might be like. Thomas Nagel (“What is it Like to be a Bat” 1974) deliberately chose an example (the bat) that to most people would have a subjective experience of some kind. Nagel’s argument is that it is in principle impossible for us to access bat-experience subjectively. His conclusion is taken to apply to any other subjective experience including that of other humans.

What would happen if we made two ELIZA programs interact? From a third-party perspective it would be a conversation between a therapist and a patient, that is two persons. But we know that this is not the case. We can explain all the behavior of both sides with reference to nothing but algorithms and programmable hardware, and we have good reason to believe that these are both necessary and sufficient causes of the observed behavior. We wouldn’t normally think to say that either side experienced any “therapeutic value”, semantic understanding or indeed had any internal experience of the interaction at all. Why not? Two reasons. One is that we do not impute any consciousness to ELIZA, and not having any consciousness, ELIZA cannot have and will at all. We normally take for granted that some consciousness is a necessary ground of any sort of willing. Will is only experienced, only exists, subjectively and never, like Hume’s cause, in the third person. My theme here focuses on the will so I want to stress the causal determinism (both necessary and sufficient) of the combination of algorithm and hardware is what robs the automation of anything that could conceivably be called “will”.

Now suppose we substitute real human beings for the two ELIZAs but stipulate that neither has a free will. The interaction is, in a manner perfectly analogous to “algorithm and hardware”, causally determined by states of the brains of the two humans. This causal relation is both necessary and sufficient to bring about every question and response there being no genuine “will” about it. So what is different about these two cases? Why (and where) can there be meaning and significance in the humans but not the automatons? The difference is the humans are (or could be) conscious – I stipulated only that they had no free will.

In the literature on free will and philosophy of mind one often finds that deniers of free will are not always deniers of consciousness. That is, although there is no genuine will there is experience, something subjective, and meaning arises in that arena. But consciousness itself is problematic for the same reason as free will. As Sean Carroll (“The Big Picture: On the Origins of Life, Meaning, and the Universe Itself” 2015) put it “thought can’t cause physics”. But if consciousness is real, then by some mechanism physics causes thought, subjectivity, and that should be equally impossible. There is, to put it bluntly, no more evidence in all of modern science that physics causes thought (subjectivity) than there is (from a third-party perspective remember the two ELIZAs) that thought causes physics. Consciousness and free will are two sides of the same coin.

If consciousness is real, and therefore experience can have meaning, then one must hold that physics causes [nonmaterial] thought. Rejecting this leaves only epiphenomenalism or eliminative materialism. The first makes experience (the subjectivity we experience every day) an illusion, while the second says it isn’t even illusory but nonexistent, something experience itself makes incoherent. Think of having a few orgasms in some clinical setting. The clinician asks you “which orgasm was the most powerful?” You say “the second.” The clinician, monitoring the behavior of every nerve in your body, says “No, my instruments tell me the first was more powerful.” The question comes down to who are you going to believe? The report of the clinician or the orgasm qualia you experienced? I stress here that it isn’t the orgasm, the measureable biological phenomena of nerve and muscle, but the subjective quality of the experience that matters.

The above example applies to qualia in general, but orgasms are particularly individual and subjectively qualified. It would be absurd to hold the third-party measurement had logical priority over the subjective experience. The quality of an orgasm is in its subjective experience and nowhere else. It would also be absurd to hold that an orgasm was illusory (epiphenomenalism) or nonexistent (eliminative materialism). An “illusory orgasm” is no more possible than a “square circle”. But none of this means there isn’t some brain state associated with every experience including experiences of thinking or choosing. If subjective experiences (think orgasms) are real, if they mean anything to a subject, there must be at least a logical separation between brain states and subjective experience. This is the gap so well described by David Chalmers (“The Conscious Mind: In Search of a Fundamental Theory” 1996 and “The Character of Consciousness” 2010), and that forces one to accept a property dualism of some sort.

In his 2015 book “Free Will a Philosophical Reappraisal” Nicholas Rescher asks us to consider that there is some brain state literally simultaneous with “the thought”. The question is not which is physically antecedent (and so causal) but logically antecedent and so initiating. Rescher is a materialist, so his scheme must work from the side of physics. He argues the relation between physics and thought is not causal in the normal sense that physics understands it. Instead of a cause he calls it an initiation. He makes two distinctions here. Initiations are atemporal. Rescher (a process ontologist) holds an “event view” of cause in which events unfold (cause) other events. What is important about all event unfolding is its temporality. Events have duration (however short or long) and “causing events” must precede result unfolding in time. By contrast, initiations are simultaneous with their physical expressions. Crucially they are not “events”. Rescher calls them “eventuations”. In Rescher’s view the eventuations go both ways. Brain states eventuate thoughts, and sometimes a certain class of thoughts we commonly call choices or decisions eventuate brain states.

Although Rescher does not try to resolve the mystery of the interaction metaphysically he doesn’t have to. What he shows is the reasonableness of the relation going both ways. If physics can evoke consciousness, then consciousness can, correspondingly, evoke physics. A second consequence of initiations is that there is some brain state just before a decision or choice in thought which is not sufficient to guarantee evocation of the brain state correlated with the thought. Of course the “thought correlate” is compatible with that prior state. It must be one of the following states that can evolve from the prior state. That it does evolve requires the prior state (or some other compatible prior state) but also the initiating thought which remember by Recher’s view is not strictly a cause. This is important because the neuroscientist need not accommodate any thought. One brain state (an event with temporal duration and so causal powers) is traceable backwards through (temporal) series of other brain states, the prior unfolding into the latter (as in ELIZA) without ever detecting the inflection point where a thought had non-temporal control.

Rescher’s distinction gives us the possibility of free will but at the cost of some logical dualism. If one accepts such a dualism then there is no unique problem with free will. But if one rejects all dualism in favor of eliminative materialism, then not only free will, but consciousness itself (and so subjective orgasm) is impossible. The only escape from such a trap is the ad hoc move of declaring that physics causes thought but not the other way around. There is no particular reason to believe this is the case however for even in this view, the basic metaphysical problem of the mechanism remains. If someday neuroscience does resolve the matter of how physics causes consciousness and demonstrates its sufficiency, it is reasonable to suppose they will discover at the same time how it is that consciousness [sometimes] causes (eventuates) physics.

My original statement “no metaphysical middle ground between free will and automatonism” has now come to the identity between eliminative materialism and automatonism. We have no reason to suppose that consciousness is real (think orgasm) and free will is not. Each must interact with physics in what might well be the same mechanism, some non-temporal cause not yet identified but that crosses Chalmers’ gap. But where does all this leave us on the meaningfulness of arguing with automatons? If you accept that consciousness is in some sense real then there is no choice but to accept some dualism. Once you accept that, there is no reason not to think that libertarian free will of some capacity is real also. If you reject this and insist on eliminative materialism then neither free will nor consciousness is real, and you must accept this in the face of that very experience that leads you to this conclusion. In short, the conclusion is incoherent and that means eliminative materialism is an epistemological nihilism.

Epiphenomenalism fares little better here. There are no epiphenomena in the physical universe apart (purportedly) from consciousness itself, no evidence that physics can cause epiphenomena. If consciousness is epiphenomenal so are its contents including judgments, thoughts, and everything built upon them; our mathematics and all of what we take to be empirical knowledge. Suppose we (and who is this “we” given the epiphenomenal nature of consciousness?) use our mathematics and science, build a real (not simulated) airplane, step into that airplane and it flies.

Is our flight experience something real (remember the orgasm) or also an epiphenomenal illusion? If illusion, what mechanism (the interaction problem) entails such a reliable connection between the illusion and the world? Physics produces an illusory phenomenon able, nevertheless, to make discoveries and use them to engineer devices that can only work if the discoveries (mental phenomena after all) match purportedly independent physics across time. Planes don’t only fly occasionally or by happenstance. Properly designed, built and maintained they fly every time. The only alternative to this extraordinary coincidence is there is no “independent world” at all.

What saves epiphenomenalism from metaphysical nihilism is that they must hold (being materialists) that it isn’t anything subjective (in this case discoveries and their connection to application) resulting in these engineering marvels, but brain states determined in an engineer’s deep past. None of what we take to be “subjective experience”, for example thoughts about airplane wings, can have any causal relation to the production and flying of airplanes. Experience tells us this is patently absurd. Rescher’s notion of initiation might help here but physics (and traditionally materialism) does not recognize any atemporal cause.

If eliminative materialism or epiphenomenalism is true then human beings cannot be anything more than complex automatons whose “initial state” goes at least as far back as conception. Possibly it goes back further, but just as an automaton cannot know what states of the world led to its being “turned on”, it would be impossible for humans to know one way or another if what fixes [illusory] choices goes back any farther than conception of your body.

Either way, it doesn’t matter because there is no you in anything that you do, choose, believe, or think. There is your body of course, but what issues from it is no different in principle than what issues from ELIZA or for that matter a robot floor cleaner. There is no reason for any conscious and free willed being to accept anything that issues from you as anything more than properly (let us say) formed propositions in the English language. The signs (words) carry standard meanings to the conscious recipient but the issuer counts for nothing being unable to have any “genuine opinion”, that is subjectively (though it may falsely report having such opinions), to consider one way or another.

Note that this does not mean that propositions expressed by automatons are not true. They may well be true, but if they are it is purely by chance that such truth is expressed through this particular channel compared to any other. There is no reason to credit the source other than to recognize the expression came from this source. The expressive vehicle has no “stake in the game”. It makes perfect sense to take the propositions of automatons seriously in the same sense that it makes sense to take a chess move by Big Blue seriously. But at the same time, it makes no sense to further argue or debate an automaton or give it credit for being clever. As clever as their behavior might appear to us (who have consciousness and free will) the cleverness (though not the truth) is imputed to the automaton by us.

Consequences

So what happens if you debate an automaton and as a result your argument and alters its behavior? Nothing is going on other than your output becoming its new input and deterministically re-vectoring the automaton’s report. There isn’t any mind there to change and arguing with it becomes nothing more than a game played with the objective of affecting the course of its behavior. One might interact with ELIZA merely to try to invoke a particular response. But note that an automaton (or other determined entity) changes our free minds all the time. How many books have I read whose contents have persuaded me to alter my opinions or beliefs? Of course we normally assume that a conscious free-willed person writes the book, but there is no reason this must be the case.

Being free willed I allow the arguments (by accepting as valid and good and choosing to alter my beliefs, behavior, motives) in the book to have the impact on me that they have. Linguistically, crediting the book with “changing my mind” is merely (usually) a proxy for according its author that credit. But the book is neither conscious nor free willed and yet the book, by my reading, and not its author, is the proximate cause of my change of opinion.

At the end of the day then debating an automaton simply makes no sense. Winning such a debate is like winning a chess match against Big Blue. On the conscious side it might be satisfying and it provides new inputs to the automaton, but we have not thereby altered any mind. No person acknowledges any “good argument” on our part. If the automaton has a designer she might come to recognize something novel about my argument. I might be impacting some mind at second order here, but among the foundation pillars of materialism an insistence there is no designer.

So what do we do with an entity who looks just like a free willed person but claims to be an automaton? There are three possibilities: 1) the entity is lying, 2) the entity is mistaken, and 3) the entity is an automaton. Notice the three alternatives concern only the status of the free will claim. An automaton can produce true propositions. Theoretically, a mind might fruitfully engage with an automaton, even learn something from it. But fruitfulness is precluded if the subject at issue is or inevitably involves the no-free-will claim. As it turns out, most philosophical issues are entangled with the no-free-will claim. Obviously metaphysics and epistemology touched above, but also ethics (any subject having any socio-political import; anything on our world involving interaction between entities that look like people) and aesthetics (can an automaton experience beauty?); all the classic philosophic sub-disciplines.

If the entity is lying there is no point in arguing because we do not know the motivation behind the lie and thus even a knock-out argument serves no purpose. If the entity is an automaton then again there isn’t any point arguing because no argument exists that would make the truth other than it is. Big Blue is an automaton no matter how hard we try to convince it otherwise. Indeed we might cause Big Blue to report that it isn’t an automaton, a mistake by the machine. Reporting free will (or consciousness) when none exists does not change the fact of the matter. We have done nothing more than caused a deterministic system to mis-adapt in a small way, a Pyrrhic victory if ever there was one. Big Blue’s mistaken report need not affect its chess playing skills.

That leaves “being mistaken” by a conscious entity. Here at least there is, presumptively, a mind to be changed. In theory, some argument can affect it, could make the conscious entity recognize that it must in fact be free willed. While possible, such an argument isn’t likely to be found. Why? Because the individual concerned believes the falsehood (often asserted by authorities like physicists and philosophers) “there is nothing but physics” and “thought cannot cause physics” (even bearing in mind the causal distinctions made above). Ironically many of these same authorities see no inconsistency in physics causing thought. We cannot prove the reality of free will or even consciousness in any logically rigorous way any more than we can disprove it. Human beings (I speak biologically here) who claim “no free will” believe this (typically) for metaphysical reasons. If physicists are correct as far as they (all science) can legitimately claim and there is nothing but physics to be found by physical means, then the only possible evidence of the reality of consciousness and free will is what we experience subjectively in the daily business of our lives.

Either we assume that human beings on Earth who deny any free will are mistaken by intellectual error, a choice (free willed) to accept a falsehood, or we take them at their word and they are not, in fact, free willed. If we take the second alternative, continued interaction is nothing more than a game played with a sophisticated ELIZA. Of course in our real world, some mix of the these is also possible. Some of those who report lacking free will are simply mistaken, while others might genuinely lack it. But all of this only matters to free willed human beings on one side or the other. If a free willed being mistakenly believes she has no free will, she might be enlightened, liberated, saved by our interaction with them — however unlikely this is. If the being on one side has no free will, really is an automaton, arguing with it about this is a waste of time.

By contrast if there is no free will on either side, then everything is a “waste of time” because all interaction would be meaningless; epistemological nihilism. There would be nothing “to know”, only what determined physical behavior, a process physics does correctly recognize as purposeless and therefore also metaphysically meaningless. Why should all of us automatons bother to do anything at all? The answer should be plain. The capacity to ask that last question cannot issue from a true automaton. To an automaton, the answer must be determined, perhaps “to maintain its existence”; not a rationale or purpose (of a mind) but a blind switching of state. To question the meaningfulness of existence presupposes some subjectivity whose experience, and so existence, it is. If subjective experience is real then physics causes (perhaps atemporally initiates as in Rescher) thought, and though obscure there is no a priori reason why thought shouldn’t cause (initiate) physics by the same mechanism.

Information, Life, and the Big Bang

In 2014 William Dembski published “Being as Communion: A Metaphysics of Information” what he calls (in the introduction) a capstone on a trilogy that began with “The Design Inference: Eliminating Chance through Small Probabilities” (1998) and continued with “No Free Lunch: Why Specified Complexity Cannot Be Purchased Without Intelligence” (2001). In the first two books Dembski spends his time building an argument about the unlikelihood of even simple life’s “information content” assembling itself accidentally on the Earth of some 3 to 4 billion years past.

Considering the Earth could only have supported any conceivable life as recently as 4 billion years ago, life appeared rather soon after supportive conditions developed. Dembski concludes (and you can read the books to follow the math) the probability of that much information assembling itself in that little time is about 1 x 10^-150. The same basic principles hold true for life’s evolution to its present forms adding an extraordinary amount of extra information along the way. Dembski understands Darwinian mechanisms. He carefully evaluates their capacity to assemble such an information pyramid by accident given the possible range of chemical interactions that occur among all the molecules of the nascent biological Earth on up to the present day. He shows again that it is incredibly unlikely for evolution to have been nothing but an accidental combination of mutation and selection.

In his third book Dembski goes on the offensive and focuses not on the unlikelihood of accidental life and evolution to present forms, but its impossibility. He does this by adding to his previous analysis a principle understood and accepted by today’s physics community; “Conservation of Information”. The concept is simple enough. A given system of mass-energy with boundary conditions (including energy flow) cannot express more information than was put into it somewhere.

To see how this all plays out over the history of the universe is the purpose of this essay. Dembski misses something important by leaving open when exactly the information needed to specify life (and next evolution) is added. Dembski happens to believe in a Christian God so he has no problem with the idea of information added to the world at life’s origin. But he leaves open the possibility the information comes not from God, but perhaps aliens. Also open is the notion the necessary information was there at the beginning, at the big bang, leading to a panpsychism, or for that matter that we are living in a computer simulation (another version of aliens) adding information as the code grinds on.

What Dembski misses (or fails to appreciate properly) is that the fundamental discoveries of physics point to a late introduction of the information needed to assemble genuine life. It is my aim here to fill in that gap. Beyond this, Dembski goes on to note that our only experience of information-creation or addition to the world is our own intelligent designs. If information is conserved, and its only source is intelligence, the universe’s initial information must come from some intelligence somewhere. Again this leaves open the possibility of super-aliens, computer simulation, or God. If Dembski is right that information is conserved, then either the universe’s information originates in some intelligence or it was all there from its beginning. If it was there from the beginning, if it was a part of the physical universe at the big bang, where in physics is it found? Does what physics finds at the beginning provide for everything from stars to conscious observers?

Information as understood by physics is of three types, Shannon information, Kolmogorov information, and semantic information. I review these more extensively in my books. A brief summary will do here. Information in all these forms is exclusionary. A hypothetically information-less collection of matter energy, displaying no behavioral regularities, contains within itself a well-nigh infinite potential of future possible states. But there is no such collection because the nature  of matter-energy and the regularities we observe depend on information. Information, beginning with its first expression in “natural law”, restricts present potentials and future possibilities. Our universe, its fundamental material regularities, allows everything from black holes to consciousness, but the possible future states of a present state anywhere in the universe, or for the whole universe, are not infinite.

On a cosmic scale, the specific history of our universe cannot have been much different than it was given its initial information. A stable universe of undifferentiated energy, mint-jelly, or Boltzman brains is ruled out of genuinely possible histories. Information configures matter-energy in some way. This is an important characteristic or property of information, more particularly its causal effect on matter-energy, and is understood and accepted by modern physics.

Claude Shannon developed formula for computing the quantity of information that could be unambiguously (clearly received) over a communication channel having a certain bit rate (number of detectable state changes per second) and some amount of noise. No information channel is noise free in the real world thanks to the second law of thermodynamics. Shannon information isn’t about any particular message, but about how much message a channel can carry. Capacity might be measured over time as it is in digital communications and radios, or in some other measure, for example the length of a DNA segment or a chromosome. The exclusion principle comes in trivially here. A particular message on a channel excludes other messages on that same channel at the same time or in the same place.

Kolmogorov information is about the complexity of a message. The message BBBBBBB is less complex than the message BCADFGE. We can re-write the first as 7B while the second requires all 7 characters in the correct order. Notice that the message FGCBAED is a different message but has exactly the same complexity as BCADFGE. Something like CCCABBF is intermediate in complexity because 3CA2BF requires only 6 characters to specify a 7 character message. Again we note the exclusivity property. Any one message of any complexity excludes all others.

Semantic information concerns what a message (information) means. Normally associated with human mind semantic information is plausibly characteristic of consciousness in general. Life, even without consciousness, displays metaphorical meaning. This meaning is metaphorical because life doesn’t apprehend it. Rather meaning is imputed to life by consciousness, and seemingly always by human consciousness. Importantly to physics, there is no semantic meaning, metaphorical or otherwise, in nonliving, material process. The purposelessness of material mechanism reflects its lack of semantic meaning. “Purposeless mechanism” and “absence of semantic meaning” are two sides of the same coin.

Information expresses itself, one way or another by configuring matter-energy whether the flow of electrons on a wire, persisting patterns, or a recognition of significance (meaning) of a configuration to consciousness. We are now in a position to understand the connection between information, life, and the big bang.

Information, the potential-reducing patterning of some chunk of matter-energy, expresses itself differently depending on boundary conditions, and energy flows. Boundary conditions reflect information in the wider chunk of matter-energy that has causal input on expression in the bounded chunk. Theoretically that would be everything in the past light cone of the inner most bounded chunk, but this is often so vast a space and time that we ignore most of it. The word ‘chunk’ here refers to the matter-energy of some particular region of space and through some bounded time. Every expansion of view to wider and wider spacetime chunks encompasses more matter-energy configured by information whose expression is in turn influenced by even wider chunks. ‘Causal effect’ is a function of forces, fields, with which matter-energy both brings about and with which it interacts. For my purposes, it matters not whether we view matter-energy as the product of fields (as in quantum field theory) or fields as a product of more fundamental matter (charged particles). Both views rest on the same fundamental information.

The first boundary conditions of our universe are the particular qualities of the forces describable in information theoretic terms. These forces restrict what can happen at any given “next instant”. When we gaze into the heavens what we see, the stars, galaxies, clusters, clusters of clusters, interlocking streams of clusters going on as far as our telescopes can peer. At the largest scales, distribution of these substructures appears random, but just inside the largest scale, there is clearly an expressed arrangement. The matter-energy of the universe is not distributed randomly at all scales. Our particular arrangement, can be described as a measure of complexity; Kolmogorov information. That state, any given “state of the universe”, changes into new states. The entire universe has a capacity, a limit, at which the evolving information expression advances. There is a limit to the rate at which change in the universe takes place. The universe has a Shannon information limit.

Cosmologists and physicists have long recognized the structures of the universe are, over-all, a natural outworking of a tension between positive energy expressed as temperature and pressure and negative energy known by its more common name, gravity. A cold cloud of hydrogen gas and dust floating around in space has more entropy than the star which eventually forms from it. It is gravity (negative energy) that reduces entropy in the gas cloud by consolidating it, restricting the freedom of its individual atoms to be anywhere in the much larger region of space that was the cold cloud. At cosmic scales, gravity is the great reducer of entropy. It does this by folding space around mass. Mass migrates inward (falls) toward the center of the folding which happens to be always what we call the “center of gravity”.

Taking entropy out of a system like this makes it more difficult for photons to escape it. Folding space compresses electromagnetic forces (constraining photons) heating the contracting gas producing more rapid particle motion, raising temperature, and increasing pressure. Eventually the gas heats up enough that fusion occurs and the resulting release of positive energy balances ever-present negative gravitational energy. But why does the balancing out occur here at this point? Why isn’t gravity strong enough to overcome fusion and keep folding space until a black hole forms more or less immediately?

The balance occurs at fusion, and gravity and pressure combine to make all the structures of the physical universe, thanks to the cosmological settings. The causal regularities we call “natural law” rest on the settings. The settings (there are some 20 of these seemingly arbitrary values among them the “cosmological constant”, the value of the “Higgs field”, the “fine structure constant”, and the “proton-electron mass ratio”) limit the ways in which matter-energy can interact. The particular interactions that occur are a reflection of the settings under boundary conditions holding at any given place and time. The settings are the minimal information present at or shortly after the big bang.

The star balanced at fusion expresses the same information as the cold gas cloud from which it formed. Both are deterministic expressions, patterning in behavior, of the same settings. At the opposite end of the size scale from stars, at the building blocks of matter (the fundamental particles of the present Standard Model) to molecules the same settings restrict behavior. At the small scales the important forces are the electromagnetic (molecular scale), and the strong/weak forces (nuclear scale). The same settings pattern matter on a different scale from the cosmological under differently relevant, microscopic, boundary conditions.

When mass-energy at a macroscopic scale is somewhere in thermodynamic equilibrium its state expresses the information present in the settings under that equilibrium. For the expression to change, to evolve, boundary conditions must change. That change rests causally on the flow of energy through the system. Change is also inextricably bound up with time. The seemingly simple notion of time is anything but simple. Is time something fundamental, perhaps even more fundamental than space (Unger/Smolin “The Singular Universe and the Reality of Time” 2014), or does it emerge from (and amount to) an averaging (as temperature is an averaging of molecular velocity) of the change in the quanta of space (Carlo Rovelli “Things Are Not as they Seem” 2016)? Does time exist at all, perhaps being nothing more than a meaning (semantic information) consciousness associates with measuring the rate of change (Julian Barbour “The End of Time” 1999). For purposes of this essay, nothing depends on this controversy. Time, one way or another, is an ingredient of every boundary condition and energy flow throughout the universe at all scales.

Significantly, when change occurs ordered patterns emerge. A star is ordered in this way compared with a gas cloud We note the same phenomena in columns of bubbles rising in the simmering water in a pot. The ordering in all of these cases is the result of a coupling between the settings, the boundary conditions, and energy flow. For my purposes below, I lump energy flow into the boundary conditions but the reader should always be aware that if changes in information expression are occurring, energy is somewhere flowing through the system. There are a few scientists who claim this emergence of order is enough to explain the eventual appearance of life, but this cannot be true. As I discuss below, life exhibits a new kind of ordering that never appears in non-living phenomena; and ordering requiring information not present in the settings directly though of course it remains consistent with them.

All the phenomena of the universe from the layout of the galaxies and down to the behavior of atoms in crystals and amino acids directly express cosmological settings under different boundary conditions, and these in turn also rest on the settings. The settings are the information present at (or within a second) of the big bang. They are information because they do what information does, they restrict or exclude possibilities by constraining what they pattern. The behavior of quarks, protons, neutrons, electrons, or the effect of gravity, isn’t random. The settings restrict the values of the forces and those constrain the behavior of everything else from quarks to superclusters.

The limits, patterns of behavior, vary as conditions change, the changes themselves “caused” (some would prefer “unfold into”) by those same regularities. Two seconds after the big bang all the settings were already in place. The strong, weak, and electrostatic forces had to exist as they now do for there to come into existence protons, neutrons, electrons, and a few nuclei of helium and lithium. Given the enormous pressures and tempretures of the environment (boundary) of the big bang in its first seconds, the building block particles where the expression of the settings. Given 14 billion years of evolution, we have the universe of today, an expression of the same settings. Up to a point.

If the Conservation of Information theorem is correct the information respresented by cosmological structure or molecules had to be put into the universe as it has evolved over time, or it had to be there at its beginning. Cosmologists today mostly believe that this information was in fact all present from the beginning, or at least within a few microseconds of the big bang. Physics and cosmology has convincingly shown the settings plus gravity explain the present structure of the cooled down universe. Granting that all of this information was present at or near the beginning from where did it come?

At first cosmologists thought perhaps the values had to be what they now are; not arbitrary but rather forced out of the boundary condition of the big bang. But a hundred years of theoretical effort to derive them has failed to prove the necessity of these particular values. The now fashionable answer is the values sprang (quickly evolved) into their values purely by accident, by sheer coincidence. Recognizing the improbability of this, cosmology and physics have spawned many theories of multiuniverses (Max Tegmark “Our Mathematical Universe” 2014) in which the settings take on all manner of random values. The idea is that given billions of such universes, it is not inconceivable that one would occur in which the settings took the values we observe. That they did so here makes the eventual appearance of observers possible and it should not be surprising that observers find themselves existing in such an unlikely universe. This idea, called the “Anthropic Principle” (Brandon Carter Krakow symposium 1973, Barrow and Tipler “The Anthropic Cosmological Principle” 1987), must be at least trivially true. Since we exist, it must be possible for us to exist within the constraints (remember information restricts possibilities) of the cosmological settings.

Of course there are plausible “intelligent alternatives”. God might have constrained the settings to obtain the physical universe we occupy, a physical universe supporting eventual life and consciousness. A few honest physicists have noted the unlikeliness of the settings would not be surprising if there is a God. Besides God, the intelligent alternatives coming from science have tended to pure science fiction speculation of super-aliens (effectively demigods) or perhaps computer simulations (also implying super-aliens). Such speculative alternatives all involve beings like ourselves only having far advanced cognitive abilities and technology. Such beings either live with us in our universe or inhabit their own universe outside our own. Either way, all the cosmological origin questions remain. But multiuniverse theories require only more physics; perhaps other physical universes of some sort. This is why the science community prefers such otherwise unverifiable speculations. But they are not better explanations. They do not, for example, extend to consciousness very well.

There is something more to notice about information re-expression based solely on the settings and evolving boundary conditions. All of these expressions, that is everything governed primarily by gravity as the source of negative energy, electromagnetism, or nuclear forces are repeating structures. Every proton is identical to every other proton, and all the galaxies, while differing widely in specific shape and size are gravitationally bound rotating collections of stars very often influenced by a large central black hole (dark matter is a part of the boundary conditions forming and maintaining these structures). If you consider any given cubic meter of a star’s interior at some distance between its center and periphery, it is much like any other cubic meter of that same star at the same distance from the center.

At almost the opposite end of universal size scales, the most informationally complex structures are homogeneous crystals and relatively simple organic molecules like amino acids which themselvs will form crystal structures under the right boundary conditions. There is a large negative entropy difference between a freely floating gas of hydrogen, carbon, nitrogen, and oxygen, and an amino-acid composed of those same elements. But that reduction, purchased in the molecular case with the energy of electrostatic bonds, is nothing more than a structure that arises automatically thanks to the settings under particular boundary conditions. From the crystallization of water (ice) to the formation of amino-acids, as with gravity, entropy reduction is associated only with the production of regular repeating structures whose variation depends solely on the nature of the settings and boundary conditions which are themselves the result of the setting and their own larger-scale boundary conditions.

This situation changes dramatically when we look at life. Galaxy formation, stars, and amino acids are an immediate response to entropy reduction caused directly by gravity or electrostatic forces under specific conditions. Once any of these arise they become stable. Only changing boundary conditions alter their stable states. Even dynamic but presently stable stars are in a stable equilibrium condition with pressure balancing gravity.

But living systems differ from any nonliving information expressions in several ways. Their stability is never merely a simple equilibrium, but rather the product of many interactions dynamically reducing entropy in the living organism over all. Of course living processes cause entropy increase in the environment, the boundary within which life operates, and there are living processes that spend heat in support of neg-entropic mechanism. Life exhibits a persistent battle against entropy and is never in internal equilibrium. If a living organism comes to complete equilibrium, or its entropic activity dominates, the organism dies. More importantly, life’s neg-entropy mechanisms achieve their effect not by the simple surrender to the consequences of the settings but rather to active mechanisms that map or translate information from one form into another. Living systems are filled with little engines that map information from one form into another reducing entropy in the system over all as a by-product. No comparable mechanisms exist in the nonliving cosmos.

The most familiar of these living mechanisms is the multistep interaction chain, associated with many intermediate structures themselves built up out of the same process, of mapping information in DNA to proteins. Obedient to the Conservation of Information theorem, this creates no new information. Rather, information is mapped from one expression to another. But the mechanism itself, a mapping engine, is new. None of this works apart from the limits imposed by the settings. But unlike stars, life’s entropy reduction is not a direct outcome of the settings, but of an entropy reducing transfer of information from one form to another.

The complexity of life frames a further limit on the space of possibility within the restriction imposed by the settings. It amounts to new information besides the settings alone. A protein’s biological functionality is not merely the result of its electostatic forces, but also its physical shape. True, the shape is the result of electrostatic forces, but an identically force-balanced molecule of a different shape will not work. Many differently shaped molecules might have identical force balances. The biological activity of a particular shape is a restriction not found in the settings alone. Life’s information is a restriction on top of a restriction and that demands more information. Where did this more come from?

Once again science, this time biology down through chemistry to physics, declares that it was all, like the settings, a lucky accident. Yes, they admit, unlikely, but not impossible and if it hadn’t happend on Earth, we would not be around to comment on it. In his first two books, Dembski explains just how unlikely such an accidental assembly is; thousands of different translations, hundreds of thousands of molecular arrangements, functioning as an integrated system, a living organism. In his third book Dembski argues that the information difference between nonliving processes and the simplest conceivable life (simpler than anything we find on Earth today) could not possibly come to exist accidentally. If life’s arrangement cannot be a direct product of the settings alone (the only information present in the big bang and throughout the evolution of the nonliving cosmos) its accidental appearance would be a violation of the Conservation of Information principle. What Dembski misses (at least I do not remember him mentioning it) is that life’s entropy reduction mechanism, complexity translation, is nowhere else exhibited in the interactions of the nonliving cosmos. From intergalactic clusters to amino acids none of the accumulated information is carried through translation mechanisms. It is all the immediate expressions of the settings under specific conditions.

For science to declare the one “life origin” event we know of is an accidental product of the settings plus boundary conditions directly is question begging and most scientists know this. “Accidental” is not a valid generalization from a single observation. Even if life on Earth originated on Mars (some cosmologists do assert this is a possibility), the question of how Mars’ life began still stands. Plausibly however, life-harboring planets around other stars are effectively isolated from one another. Life on such worlds originates and evolves independently.

What a discovery of genuine life on the planets of other stars would mean depends on what we find. Finding something indisputably alive but much simpler than the simplest life on Earth, would lend credence to the view that initial assembly might be accidental. Perhaps some life is so simple (something true also of long vanished early life on Earth) that it is not so unlikely after all. But if what we find on one or even dozens of other worlds is that all life is complex, different perhaps but on the same order of complexity as the simplest life on Earth, the hypothesis of “accidental appearance” gets all the more problematic. If, as Dembski claims, the chance of life springing into being accidentally on Earth is 1 x 10^-150, it is half as likely to have happened twice, let alone multiple times.

The rest of Dembski’s argument is straightforward. Human beings, observers in the universe, know of (that is experience and observe) only one source of new information in the universe; intelligent agency. For materialists to claim that this too, that is what we experience subjectively as intelligent agency, is nothing more than an outcome of the settings and boundary conditions, begs the same question as regards life. The “only example one has” of anything cannot be the ground of a valid inductive generalization. If the only life we ever find is complex enough to be highly unlikely there are only three possibilities. The absurdly unlikely happened, there is something fundamental that we are missing in physics, or life’s information came from the outside, from intelligent agency. In all my writing including this essay I have taken for granted there is not something fundamental missing in physics.

Physics may not be finished thanks to the problem of unifying gravity and quantum mechanics, but it has nailed a few fundamentals. It has adequately dispensed with the idea there is an “invisible force” that pushes physical regularity toward the assembly of living information. We find nothing of this in classical physics or quantum mechanics. If physics is correct as concerns its own causal closure, then life’s information had to be added at a place and time when boundary conditions were supportive. If some intelligent agency acted at life’s origin (perhaps on many worlds) then the same agency’s action, to fix the settings, at the big bang would not be at all surprising. The settings are fixed as they are in support of [eventual] developing boundary conditions conducive to life’s origination.

This notion must also apply to life’s evolution on Earth to the point of emerging consciousness, and in particular a personal consciousness (discussed at length in other essays on the blog). Over a mere 3 billion years an amazing quantity of new information (Kolmogorov complexity) assembles from primitive cells to organisms having subjective experience. Subjectivity at least begins with the higher animals, but it makes the transition into “observer status” only in human beings. Animals observe their environment in the sense of integrating sensory experience in a subjective gestalt. But being an OBSERVER implies more than mere observation, it implies recognition of meaning implicit in observation but not of the observation as such. This brings me to final consideration of semantic information.

Semantic information, taken most broadly, is prelinguistic, but not preconscious. A lion easily distinguishes between a zebra and the tree next to it. It grasps the zebra is potential food and the tree is not. The discrimination between zebra and tree has meaning to lion consciousness. Given memory and subjective experience an association links ‘zebra’ to the relief of hunger. Semantic information is transferred not by translation from one physical carrier to another, but from some such physical state to a subject. Meaning is meaning to a subject. Compared to biological information, semantic information is one step further removed from the settings. Many discrete sets of biophysical states ground a particular persisting consciousness, while different conscious experiences follow from similar biophysical states. Semantic information is largely independent of the physics underlying it and exists only to consciousness.

The uncoupling of semantic information from physical information continues in human consciousness. A zebra means [potential] food to a lion whether it is hungry at the moment or not. Both lions and humans apprehend meanings in this way, we are after all animals. But human beings not only apprehend meanings, they also abstract and evaluate them. Abstraction and evaluation combine to suggest meanings not immediately apprehended. This (and our volitional power to control our bodies) underlies our capacity to put new information into the world, literally to pattern matter-energy restricting its future potentials. Humans alone are capable of adding information, arising in subjective abstractions, to the world. Lions are not. We create art, and airplanes. Flying airplanes are like biological activity in the outcomes of information mapping engines. A successful mapping creates not only a biologically active molecule, but one that functions in a role specified by biological demands. A flying airplane signals a successful combination of semantic information and physics (purposeless mechanisms resting on the settings) whose proper role is specified by subjective intent to build a flying machine.

In a living cell there is nothing in the chain of events from DNA to a shaped protein that relies on anything other than the basic forces whose fundamental information, present at the big bang, is the settings. In this case, the electrostatic forces are dominant, but everything has its effect on the outcome. There does not appear to be anything in life that originates outside the physical world. As with the settings, once information is put in somewhere, life’s day-to-day operation exhibits nothing but outcomes explained by the forces (settings), and boundaries now including life, that cell, itself. But life’s delicately balanced self-maintenance does not address the issue of how its information originates. If the Conservation of Information theorem is true, then not only was its accidental assembly unlikely, it is impossible.

Individuals are free, of course, to believe life’s origin and evolution was accidental. But the argument that they were nothing of the kind is clearly plausible, even reasonable compared with much speculation from materialists. When we arrive at human beings, a new power springs from life through consciousness. Not only is there a mapping from some physical “state of affairs” to a meaning apprehended in consciousness, but uniquely, humans can map abstract meanings from consciousness to the world. Abstraction capable language marks the final separation between information and the settings.

The word ‘palo’ in Spanish means ‘tree’ in English. Either might refer to some particular tree or to the class or kind ‘tree’, and both are equally compatible with the settings and boundary conditions up through all of biology. All human languages are of course compatible with human biology everywhere on Earth. Expressing a single abstract meaning in different languages demonstrates the complete decoupling of semantic meaning from the settings. Completing the decoupling begun with life and continued in animal consciousness grounds both human free will and our power to create information.

This capacity, the free-willed intelligent creation (by arrangement of matter-energy) of new information, demands new information. If everything that happens in the universe expresses information, such novel power rests on information not previously present; information added not to matter-energy directly, but to consciousness. I go into what this implies in more detail in my books and the blog essay “Why Personality?”

All the information from the settings to life, supposing they come from outside physics, might conceivably (however implausibly) be the work of aliens, or perhaps we live in a computer simulation. Consciousness poses a special problem because unlike the universe and life, it is plausibly both real and nonmaterial. A corollary of life’s physical nature is that living process isn’t intrinsically conscious. Nothing about biology, however complex, suggests an emergence of subjective experience. It isn’t clear that any subjectivity can emerge from a causally closed physics; not even accidentally given infinite time! Human consciousness poses an additional problem. Even the highest animal consciousness does not display an ability to configure the world in novel ways based on new meanings conceived first (and not merely apprehended) in consciousness!

Human beings can shape the world based on thoughts whose origin has little direct connection to immediate sensory experience or memory. Of course our creative thinking includes apprehended meaning. But human creativity goes beyond experience to first postulate new, associative meanings, and then test their validity (truth content) by configuring physical subsystems that function (like shaped proteins) in their intended roles. Art, philosophy, and technology are all predicated on the validity of meanings originating in consciousness.

If aliens did this, from life (at least) to subjectivity capable of original creation, directly or in a computer simulation, they would stand in relation to us much as religion’s claims for God. Not entirely, for it is not an entailment of the alien hypothesis that aliens be for example omnipotent. If however we live in the matrix, a computer simulation, then omniscience, omnipotence, and omnipresence within the context of the program are reasonable inferences.

If the aliens are a product of this universe, the matter of the settings, and how the alien life started and evolved, appears. The alien hypothesis settles no philosophical issues. If aliens created the universe itself, and it is not a simulation then their universe must be something outside, apart from the physical as we see it from inside our universe. Even if one insists this outside is physical it cannot be “our physical”. There must, in this view, still be something outside our universe. But none of this matters because if any of these speculations are even remotely true, then something or someone added information, at least beginning with life if not the big bang, to the universe, our universe! It doesn’t matter if the agency is divine or not or if the information came from aliens inside or outside the universe. It isn’t necessary to assume that this agency must be purposefully intelligent. But evidence at least suggests that it exhibits all the characteristics of purposeful intelligence as we observers experience it.

If any of this speculation is true, physics must still give up the idea that “no such information came from anywhere”. There is some irony here. The speculation taken most seriously by the materialist community is that all we know as our world was genuinely an accident; precisely the “no information from anywhere” hypothesis. The irony is that this hypothesis is the one least supported by all the evidence, even the purely material evidence of life. Life is the first, partial decoupling from the settings. That decoupling depends on information not present in the settings. If the Conservation of Information theorem is true, life’s information had to come from somewhere other than physics.

There is nothing in physics, nothing in the strict causal closure of the physical that is incompatible with information coming in from the outside. Purposeless mechanism (a valid insight of physics) and purposeful information added by an intelligent, at least intelligent seeming, source are not incompatible. This is almost a trivial truth as concerns human experience. We configure purposeless mechanism (mechanism of the physical world) with our own purposes all the time. Our entire technological history not to mention art, science, and philosophy begin with that ability. If physics and intelligent agency get along as we experience them, and if our universe is everywhere basically the same, there is no reason to insist that agency characteristic of intelligence did not add information to the universe possibly starting with the big bang. Only an agency outside the universe explains everything, where all the information came from, including the universe, the settings. Physics cannot address itself to the nature of that agency because whether it is physical or not, it is not a part of our universe.

The Understandable Inconclusiveness of Metaphysics Part II

Picture of me blowing smoke

“Scientists inevitably make metaphysical assumptions, whether explicitly or implicitly, in proposing and testing their theories — assumptions which go beyond anything that science itself can legitimate. These assumptions need to be examined critically, whether by the scientists themselves or by philosophers — and either way, the critical philosophical thinking that must be done cannot look to the methods and objects of empirical science for its model. Empirical science at most tells us what is the case, not what must or may be (but happens not to be) the case. Metaphysics deals in possibilities … only if we can delimit the scope of the possible can we hope to determine empirically what is actual. This is why empirical science is dependent upon metaphysics and cannot usurp the latter’s proper role.”  E.J. Lowe “The Possibility of Metaphysics” 1998 Emphasis in the text.

 

In part I we saw the ultimate question “what must be true for the universe of our experience to be the way it is?” can be framed with or without reference to consciousness. For a nontheist physicist or philosopher who assumes there is nothing more than physics to explain there remain questions whose answers, while remaining implicitly physical, nevertheless lay beyond what physics is qualified to address. Typically, these are questions about cosmological origins (the origin of the big bang, the cosmological settings, and the lawful regularities so well described in mathematical terms) or the fundamental ground of quantum mechanics. Also included here would be the origin of life though this in a more restricted way than the others.

Most physicists understandably ignore the matter of consciousness in their work. After all, the big bang, our present “cooled down” universe, and life, predate consciousness of any biological variety by billions of years. The universe presents much to be studied and many unanswered questions besides consciousness. But those questions too have metaphysical implications because questions themselves arise in consciousness and have implications lying outside the measurable qualities of the physical universe. Avoiding the issue of consciousness permits focus on a more restricted set of answers to the “what must be true” question at the cost (possibly) of biasing the set of reasonable answers against consciousness. What is necessary for the universe to be what it is apart from consciousness might no longer be sufficient if consciousness is added back in. Nevertheless there is, presumably, much in and about the universe whose metaphysical grounds do not demand any attention to consciousness other than implications arising from the process of explanation. The mechanisms of the physical after all are antecedent to consciousness, but their explication is not.

Physicalism, the metaphysical doctrine that physical processes and substances are all that exist in the universe simpliciter. Physicalism entails a denial of consciousness, that is, there is nothing in the universe that is non-physical. The apparently non-physical subject must be an illusion. The philosophical incoherence of such a stance should be obvious. Although many illusions have physical explanations (for example a mirage) even these are had by subjects whose purportedly illusory nature is left out of the explanation. How does an illusion have experience, or perhaps we should ask what precisely can experience be if illusions can have it? Nevertheless, many physicists and philosophers take physicalism seriously. But it is one thing to accept that a physical phenomenon must have a physical explanation, while being quite another, and metaphysically irresponsible, to declare there are no nonphysical phenomena.

Naturalism is the doctrine that explanations for all physical phenomena need refer only to physical processes and substances. By itself this does not entail physicalism, but typically naturalism combines with physicalism by insisting that only what can be explained physically is real. Most naturalists are also physicalists. Naturalism masks the possibility of the nonmaterial by suggesting to complete physical explanations for the physical means there remains nothing more to explain. Put another way, there is nothing left for the nonphysical to explain. Another implication commonly accepted by naturalists but not entailed by naturalism is epistemological in nature; namely that knowledge of the physical, and what may truly said of it, can be determined only by physical measurement.

Metaphysically speaking, naturalism divorced from physicalism, is on the most solid foundation as concerns our present grasp of universe phenomena. Even if one were to believe there is a teleological component (for example a God’s purpose) for the universe, a causally closed and intrinsically purposeless physical mechanism remains possible. Purely physical explanations for the physical can in fact be complete explanations while discounting any talk of purpose as redundant.

Materialism is the doctrine that while all phenomena in the universe (including consciousness) have purely physical antecedents, it is nevertheless possible for purely physical processes to result in what appear to be irreducible (to physics) nonphysical phenomena, notably consciousness. Materialism is not committed to physicalism except as concerns origins even if such phenomena are not conceptually reducible to physics. This is to say that materialists who are not physicalists are not committed to the idea that consciousness is illusory or unreal. Materialists are committed to naturalism as concerns the purely physical, but they concede that from the subjective side, a purely natural explanation for consciousness may not in principle be possible. Materialists reject the epistemological implication of naturalism, that knowledge can only be acquired of the physical by physical measurement.

Cutting across these metaphysical distinctions are the epistemological notions of realism and antirealism. Most scientists are realists (there is a special exception here for quantum mechanics where realism has a technical definition linked to hidden variable theories). They believe that there is a world independent of human subjective experience, and that subjective experience (coupled with measurement) accurately informs us about composition and processes of the independent world. If our best ideas (given realism) are not in any literal sense absolutely true about those constituents, they at least approximate this truth and gradually draw (perhaps asymptotically) to it as the scientific enterprise progresses. The most troubling metaphysical response from antirealists is that the connection between what we see in our heads and what is happening in the world independent of our heads seems magical or arbitrary. Realists point to predictions derived from measurement bearing out in the world. Airplanes fly. Antirealists rejoined that some set of incompatible natures might be true of the independent world that nevertheless allowed (or explained) the same outcomes.

The argument is important to scientific work because it bears on the interpretation of phenomena related to extreme or edge cases as concerns the present status of science. Realists point out that away from the edge cases, that is within our technological capacity to experiment, there are measurements from many different perspectives. The set of metaphysical possibilities entailed by any one overlaps those of others in such a way as to cancel all but a few possible ways the independent world could be. The answer to the “what must be true” question, at least as concerns the vast number of common phenomena, is mostly if not absolutely, fleshed in. While conceding that this is not a logical proof of correspondence between theory and world it is enough to persuade most scientists of the non-arbitrariness of the connection between the mental and independent physical whatever its underlying metaphysical reason.

Scientific method has a more technical term, “methodological naturalism”. Related to naturalism in that it is the methodology by which science earns naturalistic explanations. The process begins with physical observation and measurement of physical phenomena. From the observations, science develops theories and if possible, experiments to confirm or refute them. At least this is the traditional and still frequent approach that science takes. Scientists added another approach beginning roughly in the last half of the 19th century. Theories drawn from applying mathematics to the physical world became the foundation for either experimental or purely observational searches for the physical outcomes predicted by the theory or for other phenomena that ruled out those theories. The best theories, even before any attempt at confirmation or refutation are those that predict testable necessary outcomes. Philosophically, and at least as concerns strictly physical phenomena subject to physical tests, this all makes perfect sense.

That experiments or observations can confirm or refute theories about the physical world relies on the correctness (again the realist correspondence with the independent world) of a principle, the “Newtonian Paradigm”. This asserts that a given bounded or isolated system will behave like its unbounded (real) counterpart, if the environment surrounding the bounded sufficiently matches the conditions impinging on the isolated phenomenon when taken in its natural context. If all the physical causes, events, or states of affairs that impinge on a conceptually isolated physical subsystem are properly emulated in an experimentally isolated physical subsystem, the two will behave alike. What exactly constitute sufficient limits varies depending on the phenomenon under study.

Realist scientists accept that the success of the predictive power of methodological naturalism also means that we do manage to identify the appropriate boundary conditions much of the time. But not always. In the latter cases, experiments or observations are inconclusive and it remains for science to try again. The signal, the sign that a sufficient set of limits is found is the close match between unambiguous prediction of physical consequences and their experimental and observational confirmation.

There is another assumption implicit in the Newtonian Paradigm and that is that time is real and some part of the sufficient collection of limits that cancels out (typically though not always) because it applies equally everywhere. Every experiment and every observation takes place in time as do the phenomena themselves. That time moves differently in different reference frames is not much controversial these days nor should it be. But time nevertheless moves in the same direction in every reference frame except where, at the speed of light frame of photons and potentially other massless particles, time doesn’t move at all.

The Newtonian Paradigm and methodological naturalism only work to deliver explanations for conceptually isolated subsystems of the universe. If a system has no known boundaries, we cannot construct or even conceptualize suitable limits required by the Newtonian Paradigm. The physical universe, taken as a whole, is such a system. As observers in the universe, we have no grasp of possible impingement on the universe from outside it. There are a few good scientific theories about the origin of the physical universe; the origin of the big bang itself. ‘Good’ here means these theories make unambiguous physical predictions that are hypothetically observable by present (or soon to exist) instruments.

While strictly beyond the limits of the Newtonian Paradigm, all the good theories still rely on time’s reality, literally that time existed prior to the big bang. Theories that deny the reality of time or assert time begins at the big bang (or the illusion of time in consciousness is conceived as going back to the big bang) cannot possibly have physical consequences stemming from events or states of affairs before the big bang! Because they have no unambiguous consequences in the observable universe such timeless theories of the bang’s origin are, like much metaphysical speculation, open ended and utterly underdetermined by physical evidence. Multi-universes of varying types (see especially Max Tegmark’s “Our Mathematical Universe” (2014) for a very good review of them), colliding M-Branes, or a fortuitous (for us) fluctuation in the quantum vacuum.

Even if time remains real our theories do not reach to testable outcomes before the event of the big bang, only outcomes viewed in the aftermath of it. Unlike every other event from galactic formation to atomic decay the Newtonian Paradigm applies because we can observe and measure both what passes before and what after in time. As concerns the origin event of the universe there can be no unambiguous observation of the before because there was only one such event and it is now past. Our best theories might have observable consequences now and some of these narrow the possibilities of what was before. Because they all unambiguously rely on the reality of time, they confirm the reality of time!

Concerning another of the edge cases, the quantum realm, the situation with regard to the Newtonian Paradigm is a little different. We cannot be sure the limits of force and quantity that we apply with physical apparatus, are relevant to the quantum realm. This is not to deny that quantum phenomena are physical. But it may turn out that not all of what is physical is subject, in principle, to the measurement limitations of macroscopic instruments.

All of our instruments measure, one-way or another, by exchanging energy with the environment. We know that quantum phenomena result in energy transfer as their effects interact with our instruments. But unlike ordinary phenomena, bound in our experiments by emulating the energy exchange between them and that which is outside, we do not know, for the quantum realm, if any energy transfer occurs before interaction with our instruments. The instruments measure the outcome of quantum phenomena but not what happens prior to those outcomes. Although quantum systems are small, as with the big bang, we cannot view what happens to quanta before an energy exchange takes place. We can measure quantum outcomes, but not their causes or prior states-of-affairs. We do not know, as a result, what the relevant boundaries producing the effect are. As in cosmology, the upshot is an underdetermined plethora of theories lacking unambiguous predictions that would confirm or refute them.

One of the debates currently animating cosmology and impinging on the matter of cosmological origin has to do with the presence of infinities in the physical universe. Two kinds of infinities come up in cosmology, singularities, and the possible infinity of the universe as a whole. Infinities are mathematical constructs. If, like Max Tegmark (“Our Mathematical Universe” 2014) you believe the physical universe is a mathematical construct, then physical infinities are at least conceivable and ruling out their physical possibility is problematic if the universe’s governing mathematics necessarily includes them. Black holes might instantiate genuine singularities and, in the past, the big bang might have been a physical singularity. The universe might be infinite in extent.

Roberto Unger and Lee Smolin (“The Singular Universe and the Reality of Time” 2014) unhesitatingly declare there are no physical infinities. Despite the deep connection between mathematics and physics there is no observational evidence to support the idea that what is possible in mathematics must be possible in the physical universe. As deep as the regularities in physical process may go and so be subject to mathematical description, there is no guarantee that they go all the way to infinity.

Unger puts the basic issue this way: “Everything that exists in nature, including the universe and all of its phenomena and events, results from other events and phenomena in time. Everything, as Anaximander wrote, turns into everything else, under the dominion of time.

How then could the infinite come to exist, given what we see and know of the workings of nature? The universe might be indefinitely large, and some of its rudiments indefinitely small. Its history may extend indefinitely back into the past and far into the future. There is, nevertheless, and infinite difference between indefinite largeness or smallness and infinity, or between indefinite longevity and eternity, which is infinity in time.

No natural event analogous to an process that we observe in nature could jump the gap between indefinite largeness or longevity and infinity or eternity. … Consequently, the infinite could exist only if it always existed.” [Under/Smolin 2014 pp 315].

An epistemological argument that we, that is human observers, could never demonstrate a physical infinity by any empirical means and therefore never know there are (or were) physical infinities is as ironclad as an argument can get in philosophy rooted in science. We can never know, in the sense that science yields knowledge, if a physical infinity existed. By their nature all of our instruments, and any instruments we might conceivably build are finite and can measure only finite qualities and quantities. It cannot be possible ever to measure an infinity. In his “Hidden in Plain Sight VI: Why Three Dimensions” (2016) Andrew Thomas notes that no infinity has ever been observed in the universe. It is a safe bet that none ever will be seen. The epistemological argument precludes our ever observing infinity but not its metaphysical possibility. Alas Dr. Thomas did not address the question of whether an infinity instantiated in three dimensions was physically possible.

As concerns the infinite expanse of the cosmos, most cosmologists accept this argument for the limit of our possible knowledge and for other reasons tend not to believe the physical cosmos is literally infinite. But physics is less sure about the physical instantiation of mathematical singularities. Might there be an ontological argument against the possibility of physically instantiated singularities? Since there could be no experimental measurement of infinity we cannot know if any particular property or combination of properties of the observed universe is (or are) an entailment of a physical infinity. If we derived entailments, necessary effects of a physical infinity mathematically, and they turned out to be physically impossible, we would have strong ontological reasons to reject the possibility of physical infinities.

We divide possible singularities into two types; singularities which might exist at the center of black holes, and the [possible] singularity of the only “white hole” in our universe, our big bang. It seems reasonable to link the hypothetical infinity of the present material universe to that of the big bang. Could an infinite universe proceed from anything less than an infinite initial event? If the big bang was not infinite (as Unger, Smolin, and many other cosmologists for various reasons now believe) then the material universe, however great its extent must also in the end be finite. If we can rule out the infinity of the big bang we also rule out the infinity of the cosmos.

What would be the effect in the physical world of a physical infinity at the center of a black hole? We can measure the size of a black hole’s horizon, also its mass, spin, and charge. None of these is infinite. As concerns real cosmological phenomena, black holes and the big bang, differentiated matter-energy destroyed by the extraordinary physical conditions of these events leaves but three broad properties to consider, density, temperature, and pressure. Would there not be measurable physical effects of an infinite quantity of any or all of them? Can a physically instantiated infinity have subinfinite physical effects as measured at some distance from the infinity? What does distance from infinity mean for a physical universe of three observable dimensions? Could the present universe we observe today coexist with instantiated infinity?

The physics and cosmology I’ve read is not encouraging. If the mathematics of relativity did not point at infinity this debate would not be continuing. Some physicists do believe the math signals something that exists or at least might have existed. Equally many note there is (indeed can be) no physical, empirical, evidence that all mathematical expressions represent phenomena in time. Yet in all the literature I’ve explored no one has addressed the question of the physical implications of instantiated infinity.

Some theories enable physics to dismiss the matter. One approach is to declare that at infinity the normal regularities of pressure, temperature, and density simply vanish. As a result, there are no finite physical effects of infinity. Of course there is no empirical evidence (nor could there be for epistemological reasons noted above) that such an unintuitive outcome should hold and if it did, the presence or absence of instantiated infinities could not be distinguished. There aren’t any testable results that would support any distinction.

String theorists might suggest that instantiated infinities are confined to compactified unobservable dimensions. As such they have no implications, that is necessary consequences, for the four dimensions of spacetime in which we live. In Fashion, Faith, and Fantasy In the New Physics (2016) Rodger Penrose challenges the view that events in string theory’s compactified dimensions would have no implications for the stability of our spacetime. Either way string theory is not helpful here. If Penrose is right, then infinities cannot hide in compactified dimensions. If he is not right, the possibility of infinities hidden in compactified dimensions is redundant as concerns the physics of the observable universe. As with vanishing properties their existence has no testable (confirming or refuting) outcomes. We are returned to the basic question; what would be their effects if they existed?

Even if black holes contain no singularities the question of the big bang and the potential infinity of the universe remain. A hypothesized physical infinity at the big bang suffers from some of the same potential problems as physical infinities in the center of black holes. As space expanded following the big bang event the radiation cooled yielding, in temporal order, nucleosynthesis, and then (380,000 years later) neutral atoms leaving behind the light we now see as the Cosmic Microwave Background. But why would a literally infinite big bang ever cool? Wouldn’t an infinite singularity supply an infinite amount of heat and pressure (gravity possibly nonexistent in the absence of anything with a rest mass)? Why would we expect the universe to cool no matter how much (or for how long) it expanded? In mathematics if you subtract 1 or even infinity from infinity, you still have infinity. If one is going to hypothesize a literal physical infinity would it not have to behave as its mathematical counterpart? If it did not, on what basis could we claim that it was infinite?

Is what follows from the hypothesis of a physical universe of infinite extent coherent? A few philosophers have explored consequences of the idea (an infinite number duplicate yous living lives on duplicate Earths, regions of the universe filled with mint jelly, Boltzman brains, etc). Most cosmologists do not believe the physical universe is infinite. Present models of the universe’s origin do not infer infinite quantities of matter-energy. The universe did cool as it expanded; evidence, if anything is, of a subinfinite big bang. While not a knock out argument, it is consistent with the general assumptions of the Newtonian Paradigm that we ignore what is not needed in an explanation. We’ve met the redundancy of infinity in all the hypotheses claiming that instantiated infinity has no unambiguous outcome in the physical. The same applies to an infinite expanse of matter-energy. It is redundant as concerns any observed phenomena.

Unger sums both epistemological and ontological issues this way: “The problem in supposing the world to be infinite or eternal, or both, is not just that we could never know that the world is infinite or eternal, given the infinite difference between indefinite largeness or longevity and infinity or eternity. The problem is also that the overall character of nature would be at odds with nature as we encounter it piecemeal, through science as well as through perception.” [Unger/Smolin 2014 pp 317].

Solving the riddle of infinities, either ruling them out, or showing their necessary existence, would tell us if mathematics grounds natural law or merely describes it. If mathematics controls what happens, then we live in a universe in which time emerges from interacting a priori timeless abstract structure and physical infinities are coherent. If mathematics merely describes the universe then time is real and fundamental, a primitive ingredient of a historical unfolding and there are no physical infinities thanks to the infinite gap between indefinitely large, small, long, or short, and infinity. But that gap does not address physical consequences of physical infinities should such exist. Unger notes that we cannot measure any infinity inside the explorable universe, but he directs his argument through epistemological considerations at the incoherence of physical infinities rather than the impossibility of their outcomes.

Unless physicists conclude for theoretical reasons (as there never will be any empirical reasons) that there are (or would be) consequences to physical infinities that are physically impossible (that is antithetical to all that we see), the metaphysical argument alone is not sufficiently strong. It cannot be because without that demonstration our theories can accommodate what we see with or without infinities. The metaphysical argument is suggestive and perhaps helpful if it puts physicists on the track of some theoretical examination of the physical outcomes of physical infinities, but it does not resolve the matter of infinities by itself. It cannot as long as alternate possibilities remain conceivable.

Not everything that is conceivable is physically possible though it might well be logically possible. This is an important distinction that epistemology and metaphysics presents to physics. It is important because the debate over infinities rests on the conceive-ability of the alternatives. A “knock out” argument against infinity rests on discovering the physical impossibility of their outcomes under conditions in which no empirical determination of that impossibility is possible. The track record of even theoretical physics is inconclusive here. It is possible (again logically conceivable) that at infinity all the physical laws we know are suspended or that instantiated infinities hide in compactified dimensions. In those cases, a physical universe containing physical infinities would look no different from our universe today if for no other reason than any consequence (including none) of a physical infinity is possible and nothing can be ruled out. If the mathematics did not already point to infinities, cosmologists wouldn’t be having this debate.

In 1998 William Dembski published “The Design Inference: Eliminating Chance through Small Probabilities”. He followed, in 2001 with “No Free Lunch: Why Specified Complexity Cannot be Purchased Without Intelligence”. His subject was not the cosmically large or the unreachable smallness of the quantum domain, but the origin and evolution of life. Living organisms fall comfortably midway in size between cosmic and quantum scales. Life presents itself in clearly bounded subsystems open to investigation by science. Biology rests on chemistry and chemistry on physics. Advances in the biological sciences through the past century show the applicability of the Newtonian Paradigm to life. In the 19th century Darwin’s theory of [biological] evolution provided a ground for explanation of life’s evolution, but never its origin. Even as concerns evolution however, Darwin’s work is incomplete. Some of its predictions are well confirmed by experiment and observation, but not all of them.

The problems here are not those of the very large or vanishingly small. They do not involve impossible measurements of infinity or phenomena that exchange no energy. Like the cosmos, we cannot observe the origin of life on Earth in the deep past. But there is no logical reason we could not watch life’s origin on other planets, or reproduce the phenomena in the laboratory. To date we have achieved neither. Rather these problems stem from the dramatic difference in the information content of living organisms compared to any nonliving subsystems of the universe.

Darwin’s theory asserts the environment of any given time selectively filters random changes in life’s information content. Changes inimical to an organism’s survival in its [then] environment are eliminated because those organisms (and those changes) fail to reproduce. By contrast changes that, by chance, happen to make the organisms reproduction more likely are added to the sum total of information present in that organism and its descendants. It was Darwin’s contention that information present in today’s living organisms was thus slowly assembled over the billions of years of evolution on Earth.

That evolution does take place is today indisputable, but all the observed examples involve a reshuffling of existing information, not the selective collection of new information. No one has witnessed the evolution of a more complex organism from a simpler ancestor. Although such development, increasing complexity achieved accidentally, is not precluded by the laws of physics, Dembski’s work casts doubt on the probability of accidental changes generating the sheer amount of complexly specified information in the variety of life on Earth even over the course of a few billion years.

The same considerations apply to the origin of life from nonlife. The information gap between even the most complex nonliving and the simplest unambiguous life is enormous. Modern biological science has proved there is nothing unnatural about life, only matter-energy in an extraordinarily fine-tuned balance behaving in accord with the laws of physics. I bring up the problem that Dembski poses to physics because it is an example of another blindness to metaphysical implications of physical phenomena present in modern science.

Dembski does not claim the “Abrahamic God” created life and fostered its evolution to present forms. What Dembski shows with mathematical rigor is that life’s origin and present status are unlikely to have occurred by chance. Chance is statistically, but not absolutely, precluded  Of course Dembski does believe that life and then evolution as we have come to experience it, if it is not the result of random chance must be, in part, the product of some intelligence. The intelligence need not be God, but something antecedent to life on Earth is surely entailed. There is nothing in Dembski’s core assertions that rules out a physically embodied designer, an alien intelligence, or some form of anomalous monism.

It is to the great shame of the modern scientific community that the implications of Dembski’s work are not at least properly understood and followed out. He is accused of having made no testable predictions, but the core of his work is not a theory but an observation. His observation concerns information, its quantity and quality (what Dembski calls “specification”). Present scientific consensus does not dispute the values with which he begins. Theirs is strictly an irrational (and emotional) rejection of the implications of Dembski’s observation. He may even be wrong! To decide someone will have to replicate his work and show where he makes his mistake. No one in the scientific community has taken on that task.

Physics often accuses philosophy, particularly metaphysics, of painting “castles in the air”. I have shown that physics, tied down by the physicalist assumption, paints many of its own castles whose only qualification for admission to the ranks of physical theory is that their imagined objects are physical. That such objects exist is no more demonstrable or refutable than the existence or nonexistence of God. But physics correctly establishes a universal characteristic of the physical world. The Newtonian Paradigm works when appropriately applied because the mechanisms of the physical are blind and not teleological. That this insight is the basis of a false induction, that there is no teleology imposed from outside the physical, is beside the point. Anomalous monism is false.

The only evidence of teleology in the physical world comes from cosmology, the values of the cosmological settings. All the cosmological “castles in the air” are unverifiable tries to escape the teleological implications of those settings. The settings define the entire landscape of the physically possible in our universe. On this, at least, scientists are agreed. Galaxies and living organisms are possible. A universe of mint jelly is not. The mass-energy of the big bang, given these settings, sets up the regularities of “natural law”. Physics and cosmology have well shown that these alone are sufficient to structure the universe down to the planets and their atmospheres. What physics has not demonstrated is that these regularities alone are sufficient to jump the information-gap between nonlife and life, or that they fully account for the accumulated information we see in the living world around us. If they are inadequate to these two tasks, they cannot be sufficient to explain subjectivity emerging from life.

The Understandable Inconclusiveness of Metaphysics Part I

selfie

“…metaphysics can indeed be about reality, and can avoid collapse into empirical scientific theory, provided we can learn to be content with the fact that, as far as actuality is concerned, metaphysics cannot provide us with certainties” E.J. Lowe The Possibility of Metaphysics (1998)

The central question of metaphysics might well be “what must be true to make the universe we experience possible?” As E.J. Lowe puts it in the aforementioned book “… metaphysics has been thought of as the systematic study of the most fundamental structure of reality…” The experience to which I refer includes all that we take to be an external world impinging on our sensory systems, but also the fact of experience itself, that all that impinging has a subjective result, a “something it is to be like ourselves”. In its turn, a part of that subjective experience seems to include a power, an ability on the part of the subject, to effect events in the external world without such actions being either chance occurences or ridgedly determined by antecedent events. It is not controversial that such impact is effected through the movement of a body, but from the subjective viewpoint, such movement is but the terminus of a process initiated by what appears, literally to our selves as a self, that again subjectively, appears not to be merely identified with a body, but a controler of it.

It is the present fashion in both the sciences and philosophy to claim that what appears to be a free and extra-material controller of a material body is but an illusion. Similarly, the subjective arena in and with which the controller seems to function is also declared to be illusory. There is somewhat more sensitivity in the latter claim to the matter of how it is that an illusion can appear to be something to itself? Mostly these viewpoints amount to a modern version of nihilism, but their proponents claim to be doing nothing more than following out the logical consequences of physics, that is the discoveries about the external world (the one that impinges on our senses and of course including the senses themselves) that physics has revealed. This is a disengenuous claim. Proponents are assuming that the only explanation that can be provided, and by this I mean as concerns both the objective and the subjective, is the one that physics is able (if not now than ultimately) to provide. No other explanation can count for anything other than fantasy if it is not expressible in physical terms.

This “naturalistic error” becomes quickly associated with a “physicalist error”. Because the technological results of scientific methodology at least do strongly suggest the validity of our conclusions concerning the physical world (with a few controversial “edge cases”) and coupled with the observation that a methodology employing physical instruments can only detect physical phenomena, one reaches for the conclusion that the physical must be all there is.

Physicists and philosophers who are worth their Ph.D’s all admit that this reach is an assumption. They know that there is no logical proof of the being, or not being, of anything real in the universe that is other than physical. So why this insistence of a declaration of naturalism (no explanation other than science) and physicalism (nothing but the physical exists) on the part of so many otherwise well educated people? The reasons are mostly negative. Beginning with the assumption that “there is more than the physical” that is real, philosophers have for centuries offered answers to the fundamental question (what must be true for all of this to exist) that, while they might answer the question, simply cannot be confirmed as the true or best such answer. Put in technical terms, experiential evidence (including that of physics), underdetermines metaphysical theory. In non technical terms this means that more than one such complete explanation can work and there is no objective methodology that can be used to pick out the right one.

Physics as such has reduced the ultimate question to “what must be true to make our physical world, implied by the macroscopic (and deterministic) reality we experience through our senses, the way it is?” This is a perfectly legitimate question and physics has discovered much of what lies beyond our natural (that is biological) senses forming parts of the answer to that question. That these explanations are real answers and that they are complete answers is demonstrated, again via our senses, by the fact that technology grounded in the consequences (philosophically speaking “necessary corollaries”) of those explanations actually works! Not only does it work, but we can predict to an extraordinary degree of precision how alterations in material inputs will affect (that is alter) their outputs! This means that any further explanation, any explanation that entails anything beyond or besides physical inputs, is redundant.

There do remain a few edge cases, places where our physical explanations have, at least for the moment, run up against a wall. An interpretation of quantum mechanics is perhaps the most famous of these, but the completion of the standard model, in particular the basis of gravity and its capacity to warp space is another as is the origin of life, and the genesis of the big bang. What these questions have in common is the shared, universal assumption on the part of physics, that the answers to them will form a self consistent set and that they will prove to be strictly physical making non-physical additions redundant. Interestingly though, it is with physics here at these limits exactly the same as with metaphysics in that our evidence, the evidence with which we seek to discover the answer to what must be true, underdetermines theory. As with metaphysics there are multiple possible explanations that account for the physical evidence and at the moment we have no definitive way of choosing between them.

Then there is the matter of consciousness, the observers at the end of the chain seeking the answers to all such questions. On this planet at least only humans appear to be observers of this kind. There is a general acceptance of higher animals (at least) being conscious in the sense of having a “something it is like to be” experience. But none of them (and indeed not all humans) appear to ask or care to look into the fundamentals of that experience. Still, only humans ask these questions, and only humans direct behavior towards answering them.

As an edge case for physics the matter of consciousness poses a special problem. No one denies that consciousness in some sense exists in the physical universe. But it is not, like the other edge cases, so obvious that the answer to the “what must be true” question would or could be purely physical, leaving no room for a non-redundant, non-physical component of the answer. Most physicists and philosophers today simply assume that, like everything else that physics has discovered, this limit too will ultimately prove to have a purely physical explanation. But this reasoning ignores the fact that physics can detect only the physical whether there is anything else in the universe or not; we are returned to the physicalist assumption.

Even if physics happens to be wrong concerning physicalism, metaphysics, some explanation for both the physical and the non-physical cohabiting the universe, will be unhelpful unless there is some means by which we can narrow metaphysical possibility. Underdetermination is a problem whenever the observers reach, temporarily or otherwise, some explanatory limit. Physics has a methodology (observational, mathematical, and experimental) it applies to limit the range of possible explanations though as I will show in part II the edge cases, even apart from consciousness, are often, even in principle, beyond such treatment. Even where applicable, math, experiment, and observation might not serve to pick a single explanation, but they do limit the reasonable candidates. Not all theories qualify. For metaphysics to be reasonable the same consideration must apply. There may be no method by which a single metaphysical theory can be identified as “the true answer”, but there should be some means to narrow the candidate field. Science is about what happens, while metaphysics is about what is possible.

Metaphysics has one tool analogous to mathematics, that being logic. But the validity (in the sense of being true of the actual universe) of both logical deduction and induction rests on the truth of assumptions and those assumptions (and this is just as true of physics) are made only by observers having subjective experience, the very experience whose inclusion in the universe for which we are trying to account! In turn this means that besides logical consistency, the only limiting methodology available to metaphysics is experience itself; that is a correct apprehension of it. Metaphysics must account both for physics and subjective observer experience as concerns both the fact of the latter in the universe and its content. Metaphysical answers must not be inconsistent with physics and at the same time, they must account for both the appearance of the non-physicalness of consciousness and that of free will. They must also account for all that manifests in the consciousness of observers; not merely qualia but also ideas, intension, meaning, and value.

This sets up something of a built-in circularity to metaphysics. What must limit its speculation is the very experience we are trying (among other things) to explain. The facticity of these phenomena and their purported non-material nature is the very quality open to question. To avoid a patent circularity, metaphysics must, like science, modify the central question. Not what must be true for the world to be as it is, but what must be true of the world for it to appear to us as it does. That would include the appearance of subjectivity and especially free will without presupposing their facticity.

Metaphysics has from this requirement generally suggested two broad sorts of answers to the “what must be true” question; either monism, or dualism. The physicalism already sketched is one form of monism. It argues that there is only one kind of thing in the universe that is real, the physical, including everything from the microphysical quantum universe to spacetime curved by gravity. Anything that appears to have some non-redundant non-physical aspect is only an illusion. But an illusion is a subjective phenomenon. An antecedent subject is presupposed and that cannot be an illusion because some subject is experiencing it. Physicalists have argued that the subject itself is the illusion but then who or what is it that makes this claim? Non-subjects (like rocks or statues) do not have illusions, and it is for this reason that physicalism gets around eventually to a nonsensical nihilism in which the subject making the claim denies not only his own experience, but by that the meaningfulness of the claim of illusion. As with illusions, only an antecedently existing subject can experience meaning.

But physicalism is not the only direction monism has taken. At the other extreme there is idealism, the contention that there is indeed only one real thing and that it is not the physical universe measured by physics strictly speaking, but the experiential subject-consciousness doing the measuring. This subjectivity, the “mental realm” in general is shared in the sense that we all participate, that is have our individual subjectivity, within this realm and so it is not surprising that we can compare notes as it were and recognize that some components of “the mental” are experienced by all of us accounting for the appearance of the objective world. But idealism does not satisfactorily account for our technology. It is one thing to share a mental realm and agree that a tree is a tree and a rock a rock, but it is quite another to expect to use that contingent agreement to make an airplane that flies or build a functioning quantum computer.

Just as nihilism is a nonsensical corollary of physicalism, the notion that airplanes only appear to fly because we all agree that they do is nonsensical. Airplanes do not merely appear to fly they actually fly. That means the physics underlying their flight is not merely a matter of inter-subjective agreement but a necessarily true antecedent to that agreement. Physical reality must in fact be real prior to and apart from the mental. Because monism, taken seriously, permits only a single category, there is not much room between physicalism and idealism for any other strict monism. But a less strict version appears as a component of “property dualism”.

Like monism, dualisms come in various flavors. What they have in common is an acceptance of the subjective experience, and in particular free will, at face value. The physical realm is real, the mental realm is real, and beyond this, physics alone cannot account for the mental realm unless there is more to physics than has yet been observed. What this more consists in is mostly where the property dualism debate lies. On one extreme there is no more strictly speaking, but it is nevertheless asserted that a causally closed physics, a physics that comes only from physical causes and has only physical effects, can nevertheless cause a non-physical phenomenon to emerge, and is subsequently responsive, causally, to this entity. Of course this amounts to a contradiction, a physics that has only physical effects has (or causes), at least one, non-physical effect (or emergence) that being consciousness. It does however at least underpin our intuition that the mental does have reciprocal impact on the physical; our experience of free will.

Physics is the source of the mental and therefore the mental can interact with and affect physics. This all comes out very neat and tidy until one realizes that no physicist anywhere has ever detected (measured) or observed the physical eventuating the non-physical. Causal closure does not, to 300+ years of experimentation and observation, ever appear to result in anything non-physical. One is tempted to exclaim that consciousness is indeed the only such example there is, but surely this then begs the question.

To avoid such question begging, some philosophers (but understandably no physicists) have suggested that there is something hidden in physics, that is hidden in causal closure, that remains undiscovered and is specifically directed at producing subjective consciousness. One problem with this is that like subjective experience itself, these hidden properties are not measureable with physical instruments. They are merely presumed to be present because, after all, consciousness exists and there is nothing in the measureable properties of the physical that appears able to explain it. This really is more “begging the question” based on a non-negotiable faith in physicalism, but faith is indeed the right word to use here.

Philosophers have suggested several variations on these “hidden properties”. Anomalous monism (Davidson and Nagel) lies at one extreme; un-measurable properties truly hidden either in physical law (process) or the properties of objects as we otherwise know them. Their redundancy as concerns physics strictly speaking should be enough to dismiss their presence. On the other side we have those like David Chalmers who suggest instead a set of parallel laws, not strictly in physics but present (pervading the universe) along side it. This approach avoids the issue of redundancy because these parallel laws become noticible only after the emergence of observers who notice them indirectly by having a subjective experience. That is, the measure of their presence is their detection by the phenomenon of subjective experience. This idea leads directly to some form of panpsychism whose effect, prior to the emergence of consciousness, must have driven otherwise contingent physical outcomes towards life and ultimately consciousness.

This is not an entirely unreasonable hypothesis, but its problem is again the nature of the physical. There is nothing we are aware of in the phenomenon of the big bang or anywhere in physics that would serve to support either the reality or the efficacy of a parallel set of psychotropic laws. We may not know why the big bang occured, but at least there is the manifestly unstable quantum vacuum. The quantum vacuum can be manipulated (mathematically modeled) to generate all of our physics, but not anything of panpsychism.

It is exactly the fact that there appears to be nothing in physics that supports panpsychism that leads away from property dualism where the dual-reality must have its ground in physics to substance dualism in which the ground of the mental purportedly originates, reasonably enough, outside of physics. The “psychotropic laws”, after all, stand in exactly the same relation to consciousness no matter where they originate. If they cannot come from physics perhaps they originate in something else? But what? An external origin relieves physics of incompleteness at the cost of suggesting some other quality of the universe that is not only non-material (and as such capable of grounding psychotropic laws) but must have the power to interact with physics to produce all of what the mental, to common experience, appears to produce; including free will.

It is for this reason that substance dualism is so often associated with theism or deism. Although these solutions do not explain the mechanism of the interaction, they posit an entity, a God, who knows the trick. We further ascribe self-cause to that entity to block an otherwise infinite recursion of metaphysical antecedents. Personally I do not find a theistic solution to the ultimate question unreasonable. It is certainly coherent, and as concerns an “inference to a best explanation”, a legitimate limiting test recognized as generally valid where more rigorous inductive or even deductive proofs are not applicable, theism is complete. That is to say that beginning with a few assumptions as concerns the nature God must have to be an explanation or an answer to the ultimate “what must be true” question, one can show that the corollaries of these assumptions are both consistent with physics, and all of experience including qualia, intensionality, intellection in its broadest sense, and free will.

In particular theism can account, in the sense of providing explanations, for the juxtaposition in the universe of purposeless mechanism (what physics probes) and purposeful free will (the choice of the physicist to probe it), something that materialism has been singularly unable to do. I have written three books exploring the theistic inference to best explanation of human experience and more recently “Prolegomena to a Future Theology” laying out a minimal and consistent set of axioms from which the rest can be derived. I will not further explore this subject here. In part II I will explore what philosophers, and physicists being philosophers, have proposed as explanation for why the physical universe is the way it is even leaving consciousness aside. All of these suggestions are made assuming that theism is not true, that no God exists. Yet while remaining anchored ostensibly in the physical all of these hypotheses suffer from the same problems as metaphysics in general and theism in particular as concerns physics; among them underdetermination and redundancy.

The Nonsensical Notion of Compatibilism

blackhatsmirk

Compatibilism is a philosophical attempt to rescue personal responsibility from determinism. The idea, now fashionable in scientific and philosophical circles that, thanks to an ultimately deterministic macro-universe, libertarian free will is an illusion. The libertarian part is important because compatibilists are so named precisely because they claim that we can be responsible for our acts even in the absence of our capacity as agent to initiate novel physical chains of events (through control of our bodies which are indisputably physical). Initiation is the key here. As Lowe points out (“Personal Agency” 2004) when I elect to raise my arm it is my brain and its physical connection to physical nerves, the nerves to muscles, etc. that actually controls the physical motion of my arm. That is the micro motions of my arm, the exact speed with which it goes up, exactly how high, and at exactly what angle, etc are all controlled by a physical chain of multiple events in my nervous system coupled with the capabilities of my muscles. What I do as an agent is initiate this process by choosing to raise my arm in a general sense with such and such a force, in so and so direction, etc. In order to be libertarian, that choice has to be theoretically prior to any physical causation. I might raise my arm because I want to ask a question of a lecturer, but that reason is not the cause of my arm’s going up because I could just as easily have chosen not to ask a question at that moment. Nor does any activity in my brain outside my conscious control force me to raise (or not raise) my arm. For libertarianism to be real then, there must be some agent who has the power to “initiate physics”. It is exactly this power that is denied these days by a large number of scientists and philosophers.

I think compatibilism has problems on several levels but before I get to them let’s look at what compatibilism says. The basic idea here is that if some act of mine is not coerced by an external agent, then I remain responsible for it even if in the end the act was foreordained by some prior set of physical events ending in my brain and thus the act itself. If someone puts a gun to my wife’s head and threatens to kill her if I do not rob a bank, then I am not responsible in any full sense for robbing the bank. If on the other hand there is no gun to my wife’s (or my) head then I am responsible for robbing the bank even if that act was not a libertarian choice but rather the culmination of prior physical causes, that is brain activity. Notice however the key requirement for agent coercion in the compatibalist view. Suppose I am far from home, tired, cold, and have no money. I choose to break into what appears to be an unoccupied house merely to get warm and spend the night. Surely I am responsible for that act. Now imagine that it isn’t tiredness that drives me but a hurricane from which I wish (naturally enough) to take shelter, so I break into the same unoccupied house. Neither act involves agent coercion and any court would find me guilty of breaking and entering in either case. In the latter case, the court might forgive my act because it would be reasonable for me to believe that by remaining outside the hurricane threatened my life. But I remain responsible for the act. By contrast if a man (an agent) put a gun to my head and threatened to kill me if I did not break into that house I would not be judged responsible for it.

So lets have a look at this… If I am coerced into doing something under threat of death from another agent then I am clearly not responsible for that doing in any normal sense. But given the assumption that libertarian free will is an illusion, why does agency coercion make a difference? Presumably if not coerced I would not rob the bank, but what about the agent who coerced me? Supposing he was not himself coerced into putting a gun to my head, a court would say he was responsible for that act. But since libertarian free will is an illusion, his behavior was determined in some sense by his brain in someway over which he had no prior control. Indeed even if I was not coerced, I too had no choice in the matter because my behavior also was determined, if not by coercion then by events in my brain and their causes and their causes and so on all the way back to the big bang — or at the very least to my birth.

The difference between the gun to my head and the hurricane is that in the latter case we might presume I had some alternative than breaking and entering. A hurricane might kill me, but then it might not. But the same thing cannot be said concerning brain events. The universe may not be an agent, but its deterministic imposition is even more sure in its result than a gun to my head. I might, after all, fight off an armed man, but I cannot fight off the causal outcome of a brain state over whose particulars, the result of a long chain of events, are beyond my control.

In effect I am an automaton differing from a more conventional automaton only in degree and not in kind. Even today we can build highly adaptive automatons so our appearance of adaptiveness is hardly a counter argument. The difference is only that the conventional automaton’s fixed state, its starting state, goes back only as far as when it was first turned on. Mine goes back at least to my birth, and if we take the metaphysical implications of the sort of determinism we are talking about seriously, all the way back to the big bang.

Returning more directly to compatibilism, besides the matter of prior determination, by a coercing agent or the universe, there is the problem it presents for the notion of agency itself. Libertarian free will is dismissed on the grounds that there is nothing in physics that supports it. But the same can and has been said about mind, consciousness in general, and the experience of agency, our subjective awareness of a self that appears to have an internal arena (consciousness) and the power of libertarian free will. There is nothing in physics that supports those either! If purely physical processes can cause to emerge a subjective that appears from the experiential inside to be non-material, there is nothing in physics that would permit that epiphenomenal entity to have any downward effect on physics. Physics might recognize an utterly illusory agent (although the ontological status of illusions is problematic), but the illusion cannot be permitted to effect a change in physics. If it could, then any such effect might in fact be the freely chosen act of an ontologically genuine (given that an illusion cannot cause physics) agent, the very notion rejected as being impossible.

How can an agent coerce me if the agent is an illusion and cannot affect physics? A man with a gun to my head is merely another automaton. Of course I will follow instructions and rob the bank because an additional layer of coercion has been added to that which determines my choices anyway. If there had been no gun to my head I would not rob the bank, but that course too would be the outcome of a deterministic chain. There is nothing in physics that prevents the behavior of one automaton from becoming part of the input to which another automaton adapts but either way, there is no agent acting, only a zombie (albeit a complex zombie) body, so the relation of agency to compatibilism is incoherent. Without libertarian free will the agent is no different from the hurricane. By denying libertarian free will and resting compatibilism on the presence or absence of a coercive agent, philosophers are resting a doctrine of responsibility on a redundant illusion. I am coerced by circumstances no matter what I do and no matter if there is an “agent-automaton” present or not.

If libertarian free will is genuine then we are already responsible; we are agents of our will and must own our acts. We don’t need compatibilism. But if libertarian free will is an illusion, no compatibilism will recover our responsibility because (1) the very notion of “agency” becomes problematic, and (2) even if the agent notion were somehow coherent, its behavior is determined at some level with or without the presence of a “coercing agent”.

Truth and Truthmaking

selfie

I recently finished an interesting book of modern philosophy on the subject of my title called “Truth and Truth-Making” (2014), a collection of essays from the 1980’s to 2013 edited by E. J. Lowe and A. Rami. The basic idea reflected in all of these ideas is that “truth” is something born by propositions, and that what gives propositions this property is something in the world independent of human mind. Generally speaking this idea makes sense but there are a few complications because we can find examples of propositions that seem true but do not seem to be connected to anything in the world independent of mind. Various solutions to this come to mind, the simplest of which allow of several kinds (as in categories) of truth-makers some of which are independent of mind, while others are themselves constructs of mind.

So truth here gets little attention which goes, rather, to the relation between truth-bearers (propositions) and truth-makers, something besides the structure of the proposition itself (if applicable) and [mostly] independent of mind, that make the propositions true. Most of the work in this arena is focused on what sorts of things “in the world” are or can be truth-makers, and in exactly what the relation between true propositions and their truth-makers consists. Truth-making, in turn, is a new twist on once popular “correspondence theories” of truth. If “the sky is blue today” is made true by there being a cloudless (unbefouled by pollution) sky above us today, then the proposition is true because its content corresponds to the color of the sky and the color of the sky likewise corresponds to the semantic content of the proposition.

It isn’t clear that this symmetry makes sense. It isn’t obvious that the color of the sky (which after all takes no notice of us) corresponds in any but the most trivial sense (because we say so) to the semantic content of a mental construct. The idea behind the truth-maker idea was that the relation is asymmetrical. The proposition “bears truth” because of the color of the sky (is made true by it), but the proposition, while true, does not make the sky blue. More precisely, the relation is non-symmetrical because the fact of the sky’s color has no particular relation at all to the proposition made true by it.

Propositions having to do with the state of the material world are therefore made true (or not) by the state of the material world. This then excludes “analytic truths” like “bachelors are unmarried men” which is made true by the definition of ‘bachelor’. When we speak of “the state of the material world” (and therefore “synthetic propositions”) we speak of something we call “facts”. Facts can be about various sorts of material states. That “water is H2O” is a proposition made true by a state of the world that has been a fact since recombination 340,000 years after the big bang, and will presumably remain true (subject to the evolution of natural law) for billions of years to come. By contrast, that “Mars, Earth, and the sun aligned on April 8, 2014” is made true by the fact of an alignment on that date, while the proposition that Mars, Earth, and the sun align approximately every 778 days is made true by the relation between the orbits of Earth and Mars, a state of affairs made true by those orbits since the stabilization of planetary orbits some 4 billion years ago. In each one of these cases, it is some fact that makes the proposition true. This can be restated as the proposition “expressing a fact”. Substances and processes entangled with the physical world can all be construed as facts. “John exists” is a fact if John is in the world at the time of the utterance. “There exists a John” is a fact if any person (or perhaps animal) named John exists.

Truth makers are of minimal and maximal sorts. The maximal types are typically less interesting because they are less specific. The examples given above are minimal truth makers. The state of the whole universe at any given moment is the maximal truth maker for all the facts of the universe in that moment. As such it doesn’t tell us very much. In the most maximal sense, all physical phenomena, even individually, are made true by the state of the entire universe. Every fact is “made true” by those phenomena that belong to it alone, and also by the universe as a whole. Truth-makers are not mutually exclusive. Most often they are nested together, the more minimal inside the more maximal. Notice that it isn’t merely the existence of the universe that makes every true proposition true, but the form of its existence, the way things (which might have been otherwise) actually are. The alignment of Earth and Mars with the sun [roughly] every 778 days is not made true merely by the existence of planetary orbits, but by the specific relation between the orbits of Earth and Mars.

A fact always involves some arrangement of physical substances and processes. In the temporal dimension, facts are “real” in the present. Some facts come into existence (for example that Caesar was assassinated) and then remain true forever more. Caesar was murdered over 2000 years ago, but that he was murdered is still true today. Other facts come to be, remain true for a time, and then cease to be facts. That Matthew is 12 years old was a fact for a year many years past, but is no longer a fact. It remains a fact however that Matthew was once 12 years old. There are not two facts here only two expressions of the same fact viewed in different temporal perspectives. The totality of facts in the universe consists of the past, the history of the universe, and such facts as are made actual, physical arrangements, brought into being in the present in a process of dynamic evolution.

There are philosophers who would say that while facts perhaps were reified in the past, they are real only now, that is in the present. The past is no longer real though it was real. There is only the present, and in the present there are facts that, among other things, can be records (in the present) of events in the past. Either view may be used to connect contingent propositions, facts of history that might have been otherwise, to their truth-makers in physical states-of-affairs. The proposition that “Caesar was assassinated” is made true either by that event more than two thousand years ago, or by present records of that event. That there are such present records is explained by the event’s occurrence in the past plus the further fact that the event was recorded, and the recording has survived to the present. Either way some arrangement of the physical is involved.

What are we to make of the proposition: “more often than not it is better to tell the truth than to lie”. If this is true, something of what we might mean is that the physical out workings of truth telling are on the whole better and those of lying worse most of the time. The qualifier is necessary because there are certainly situations, specific potential arrangements of substances and processes (for example Nazis searching for Jews hidden in your basement) in which it seems that lying results (one is to hope) in far better outcomes. Both the propositions “Often it is better to tell the truth” and “sometimes it is better to lie” can both be true now, in the present, when most realists agree, truth-makers must exist if they exist at all. Significantly, the “better outcomes” referred to are not yet facts. If the proposition bears truth it is because a future corresponds to it, a future having no facticity whatsoever in the present. The truth-maker for this sort of proposition cannot be a physical state-of-affairs because such a state of affairs has not yet occurred. It isn’t yet real.

A more traditional view of truth, one often connected to theism for ontological reasons I discuss in a moment, is that truth is one of a family of universals called “values”, the other members of this family being beauty and goodness. One of the reasons, perhaps the main reason, why modern philosophy has mostly abandoned an examination of truth as such and turned to talk of truth-making and truth-makers is because values, being entirely entities of the mind are both unavailable to third-party investigation (there is no objective accounting for taste in beauty for example) and in addition do not seem amenable to logical clarification (witness the multiplicity of moral theories).

In modern philosophy, where “value talk” is allowed, it is generally assumed that the three values (truth, beauty, and goodness), in addition to being experienced in mind, are also (and merely) “inventions of the mind”. Of course this is controversial. Just how it is that they are inventions, and what they mean for us as rational beings with individual purposes is the core of the modern debate if it is debated at all. But on one side of this debate are those who point out that in the end values can only mean something consistent and universal (that is for all minds) if they are not mere inventions, but come from somewhere. Mind, rather than being an inventor of values, is a detector of values.

It is this conception that leads in the end to some concept of God or proxy for God because human mind, at least, has not been able to grasp any other concept that would reify them! Science does not find these values in its examination of the material world as such. If one says “values come from the gods” (small ‘g’) one has to ask the question “who made the gods and how is it they have such power?”. If values are the result of “a force” (perhaps panpsychism) unsupported by deism or theism, one has to wonder how that quality arises from physics alone and how it comes to be that values are detected specifically and only by persons and not animals who, after all, might have quite sophisticated minds?

Philosophers have been seeking ways to ground values as something more than “mere inventions” but without resorting to theism for a long time. None of the proposed alternatives is without serious problems. One way or another, the only stopping point to the issues raised by the problems ends up being an infinite, personal, and purposeful God who’s character qualities are reflected to human minds by the values. The values constitute our sensitivity (such as it is) to God’s character. Much of this path (and the reason only humans detect values) is covered in two of my books and various other articles in this blog. Here I want to focus on the relation between truth qua value and truth in the modern idea of a property of propositions made so by something in the world.

It will be helpful to summarize what is common to all three values supposing them to be in some sense qualities of God detected by human mind. One supposes God (should he exist) must have qualities. God is said to be spirit and the human detection of values, it is traditionally supposed, is the sum and substance of what we, as limited beings made of meat in a finite universe of purposeless mechanism, can sense of those qualities.

We cannot say what spirit is only that what we can know of it is encompassed by our capacity for values detection. Our detection capacity is not to be taken as the totality of the quality of God’s spirit but only a minimal contact in the same sense as dipping one’s toe into the Pacific Ocean is contact with that ocean. It is precisely that minimal contact necessary and sufficient to qualify us for person-hood (see my “Why Personality“)! Nor should we assume the human capacity to detect values is the best that can be managed in the universe, even among creatures made of meat. It might well be that there are other meat-based creatures in the universe who by the properties of their biology have a natively-richer appreciation for the nature of the same three values. Be that as it may, our own, human, capacity to detect them is what we have, and we must grow our appreciation from our biological starting point as our alien betters must begin from theirs.

Beauty is value as it is detected in the physical world itself. When we use the word ‘beautiful’ literally, we are typically talking about some arrangement of substances we are able to perceive with our physical senses. Goodness is value detected in the acts of persons; value detected in personality as reflected in its actions. It is the acts of persons (and by extension the agents of those acts; the persons themselves) that are good. We might impute goodness to the acts of animals, but animals do not act “for reasons of values”, but only from the constraints of their biology. Goodness reflected in animal actions comes out to fitness, and the goodness (now a metaphor) for fitness, is something recognized only in human mind. This can be seen even more clearly as concerns the state-of-the universe. We might say “it is good that the fine structure constant is what it is or we would not exist”. Here we clearly mean that the fine structure constant’s value is fit for life in the universe as we find it. Clearly it is ourselves, that is human beings, who impute goodness to this measure of fitness. Truth is value not only perceived in mind (as all must be) but as concerns the content (for example beliefs) and judgments of mind. Propositions, after all, are products of mind, and notably products of human mind. As concerns beauty and goodness philosophers have quibbled over the dividing line between humans and animals, but I don’t know of anyone who takes seriously the notion that animals entertain propositions.

The values, being as it were detectable signals of God’s qualities, must be related to one another and must, like the relation between quantum mechanics and general relativity in the physical universe, end up being consistent with one another. Self-consistency, an absolute lack of self-contradiction, must be a quality of an infinite God. The values cannot be inconsistent with one another as they are recognized in their different domains any more than two extant physical phenomenon can be mutually contradictory.

That value propositions have any truth value is controversial in philosophy today, but their truth value is easily accommodated by their relation not to physical states-of-affairs, but to values taken to be qualities of God detectable by human mind. It is in some ways unfortunate that the word ‘truth’ is employed in its meaning as a value, and its being the quality of a proposition. For now I will call the value sense Truth with a capital ‘T’ and the propositional quality truth small ‘t’. So it happens that some sorts of propositions bear truth by their relation to Truth rather than to states-of-affairs. Remember that a truth-maker must be independent of the subjectivity of individual mind. If the values are merely invented in subjective experience they cannot be truth-makers because there is no guarantee that we do not each experience completely different qualities of them. But if value is detected by mind then it is possible for value to serve in the role of truth-maker. Although it is detected only by mind and thus subject to some individual distortion it has, nevertheless, enough shared quality across minds (human minds) to serve as a connection between the proposition and something outside the proposition-conceiving mind.

What does it mean to say that there is a connection between a proposition in mind and Truth conceived as a value detected in mind? As a value, Truth represents or stands for (to the limits of our capacity to detect) some quality of God. To be connected to a value is to be aligned (however incompletely or imperfectly) in some sense with some quality of God. Since God is unified and all his qualities perfectly compliment one another, it amounts to being aligned to some degree with God over-all. This is equally true for beauty and goodness as it is for truth. But as concerns truth the alignment specifically concerns mind and so to the subject matter of propositions, as beauty is to arrangements of particulars in the world (which are also states-of-affairs but truth-making does not preclude there being multiple truth-makers in certain circumstances), and goodness to the acts of persons which also, as it happens bring about various states-of-affairs.

As concerns facts, truth and Truth can come apart. “ISIS has murdered many innocent people” is true on most accounts, but its truth (small ‘t’) does not appear to have anything of goodness or beauty in it. If it is related to God at all it is only indirectly though its connection to a fact. If God exists, then all facts are related to him in a trivial sense because everything must be subsumed under God if he is God though this does not mean that he is personally responsible for them. Actual history has this relation while fantasy history does not. But the truth of a proposition made true by a fact need not have anything good or beautiful about it and its relation to Truth (capital ‘T’) is limited to its being made true by a fact whose actuality is subsumed by him. God apparently permits (at least for a time) much that contravenes his personal will. But Truth conceived as “quality of God” and truth as a property of propositions are not entirely unrelated. In an earlier essay (Process, Substance, Time, and Space) I introduced E. J. Lowe’s “Four Category Ontology”. It will be useful to review that here as it is a structure that works well to explicate the part values play in truth making.

Kind/Type ————- Attributes

Universals
——-
Particulars

Objects ————- Modes/Tropes

Kinds –> Characterized by Attributes, instantiated by objects
Objects –> Characterized by Modes, instantiated by kinds
Attributes –> Exemplified by Objects

We begin with a square. The top two corners are universals, the bottom two particulars. In the lower left corner are “individual substances” normally taken to be material and abstract things of the world both natural and artifactual. Particular planets, stars, dogs, trees, chairs, statues, people, sets and propositions can all serve as particulars. In Lowe’s view there are no “bare particulars”; every one of these objects (concrete or abstract) is a member of one or more “kinds” or “classes” (the upper left corner). My dog, for example is a member of the class “dogs” and also “animals”. Most classes nest wholly within super-classes (like dogs and animals) but this is not always so. A statue made of clay and one made of bronze are both kinds of statues, but one belongs also to the class of bronze artifactual objects while the other belongs to clay artifactual objects. The kinds instantiate global universals (upper right corner) which Lowe calls “attributes”. These globals include such abstract concepts as “color”, “shape”, “size”, “mass”. Taking color as a universal attribute, it is instantiated in classes like “red things”, “blue things”, etc. The last corner (lower right) are individual “modes” (Lowe’s preferred term) or “tropes” As with the classes, these also instantiate universal attributes, but this time as a “particular red”, or a “particular shape”. In turn, the modes are instantiated in the individual substances (back to the lower left corner). An apple has a particular shade of redness, a particular size, and a particular roundness. Particular sets have their members.

There exists a diagonal connection of “exemplification” between the lower left and upper right corners. Particulars exemplify attributes but they do so indirectly. The direct relations are only those represented by the sides of the square. Attributes are instantiated in kinds and modes, while these two are instantiated in particulars; individual substances. In Lowe’s view, only the individual substances “exist” in the sense of being objects in the physical universe. Kinds, attributes, and modes are real only insofar as they are instantiated (the Attributes via their instantiation of kinds and modes) in individual particulars. The class “unicorns” doesn’t exist if there aren’t any unicorns, and the likewise the mode of a size or shape of unicorn horn. There are no uninstantiated kinds, attributes, or modes. Lowe was a realist. Attributes exist (though not as substances) because they are instantiated through classes and modes in real particulars. The classes or kinds are abstractions exemplified by particulars, but the modes are not abstractions. They are real because they inhere in the particulars that instantiate them.

In Lowe’s view, it is the modes that establish most facts (the particular redness of an individual apple, the specific characteristic of Earth’s orbit around the sun) and thus ground the truths of propositions. But there are exceptions. Existence is not taken to be a property like a color or shape. “The [particular] apple exists” is made true by the apple itself, the particular, while “mammals are animals” is made true by the relation between the class (kind) “mammal” and the kind “animal”, in this case that the former is wholely subsumed by the latter.

Values, taken as a whole, i.e., the “qualities of God” to which our minds are sensitive belong to the attributes. These in turn are instantiated in three classes, beauty, goodness, and Truth, and also in modes corresponding to particulars that are beautiful, good, or True. A particular sunset and a particular rose are both beautiful. Each is an instantiation of the class “beauty” and each has its own particular mode or beauty trope. Individual acts are good likewise by being examples of the class and in having their own modes. What about Truth? In contemporary philosophy, truth is taken to be instantiated in (a property of) propositions, that is particular individual propositions. As a group, they are members of the class of propositions and each of the true propositions instantiates some specific “truth mode”. It is here in the particularity of the modes that the truth makers for value propositions are mostly to be located.

The modes ground value propositions in the same way that they ground propositions pertaining to the physical world. But in the case of values, the classes (Truth, beauty, and goodness) are not related in the same way as “animals” are related to “mammals”. They are each a distinct class, beauty being value reflected (to appropriately sensitive minds) in the material world, goodness reflected in the acts of persons, and truth in propositions or statements generally. “There is truth” is not grounded in a particular truth as was the case with existence, but in the presence of the class, while “truth is good” is not grounded in the class as was the case with “mammals are animals” but in the collective universal attribute values.

Classes, attributes, and modes can all have internal relations. Relations between modes often serve as truth makers for propositions about the world. The Earth’s “orbital mode” and Mars’ “orbital mode” are related such that they line up (with the sun) every 778 days. The proposition “Earth and Mars align with the sun every 778 days” is made true by the relation between their two orbital modes. One of the powerful features of Lowe’s ontological scheme is that it fits such different sorts (kinds) of particulars as chairs, statues, and propositions. Using this scheme we can see that truth as a property of propositions and Truth as a quality of God are related in that the truth of a proposition has to do with the modes instantiated by it. In the example above, they are the modes of two orbits and that these two modes are modes of orbits in the actual universe.

Lowe’s ontological scheme thus proves very flexible as concerns both propositions about the physical world and values. As concerns Truth (and truth), both fit nicely in the scheme while the scheme itself connects them or relates them as modes instantiating different universal attributes, the universal “history of the universe” and the universal “qualities of God”.

 

Response to Criticisms of Agent Causal Libertarianism

selfie

I’ve just finished a short book “Freedom, Responsibility, and Determinism: A Philosophical Dialogue” by John Lemos, Hackett Publishing 2013, an introduction to philosophical issues surrounding free will. Lemos explains several variations (each) of Incompatibilism, Compatibilism, and Libertarianism as concerns free will. As concerns Libertarianism, he discusses three variations, the first being “agent causation” and the other two (indeterminism and “indeterministic event-causal”) trying to do (unsuccessfully I think) without the agent. As concerns agent causal libertarianism he notes three types of objections. Because my view of free will, derived from the theology reflected in all of these essays, is of the agent type, my purpose in this essay is to respond to those three lines of criticism.

In the theistic view I hold, the agent is the person, personality being a non-material “information extra” on top of non-material mind. Higher animals have mind, but not personality. God can distinguish this extra pattern (he puts it there), but we cannot. To us, the mind-personality combination just looks like mind, like consciousness, our “what it is to be like” experience. Human subjective experience is an amalgamated whole, a mereological sum consisting of everything that goes into mind, plus personality. No experience of the person takes place outside of mind, and every decision of the person occurs within mind’s all encompassing embrace.

In my essays on personality and free will I explain why we must infer personality even if we cannot discern it. To summarize, we must infer it, among other things, because we experience our exercise of free will, something that a fully macro-deterministic and micro-random universe (which would include mind in the absence of personality, higher-animal mind) cannot support in the absence of a crack in physics, a crack that allows for genuine causation, and not merely event-unfolding. My view is fully committed to agent-causal libertarian free will not because of any crack in the physical except as concerns personal agency. It is plainly what we appear to experience from our subjective viewpoint; not as concerns every choice we make, but in many of them throughout our lives.
Objections to agent cause are of the following three types:

1) Uncaused cause is not scientific, nowhere supported by physics.
2) Agent Cause does not solve the “luck problem”.
3) Agent Cause is incoherent because agents persist while the events they cause happen at specific times.

The first objection comes down to scientism. Physics allows for exactly two types of causes, and in addition causal language is taken to be naieve. For physics, events, that is physical events including the movement of biological bodies, unfold into subsequent events. Thus there are two broad types of events, those that are determined, and those (quantum events) that are fundamentally random. Because of quantum randomness, physicists concede that the macro-level of description is not entirely determined, but to the extent that it is [slightly] undetermined, it is [slightly] random. There is no room in our physical description for purposeful, that is original and  non-random cause; an event that occurs without any prior event other than the undetermined (more precisely not fully determined) but purposeful choosing of an agent.

This objection is question begging. The agent-causal claim is precisely that there is an exception to the two physical possibilities of determinism and randomness, and the exception is specifically personal agency! Agent causalists do not claim that the free agent is physical even as they of course concede that their bodies are physical. For physics simply to declare that no such non-physical thing can exist because there are only physical events having physical (determined or random) antecedents begs the question of agency being the exception.

On the theistic view, the exception is not problematic as God himself produces this exception, configures it on consciousness in time. Other than how he produces it, there is no “interaction problem” because the person is a cause only in mind. The interaction issue remains between mind and body and a topic for another essay. Non-material agents can be a cause in physics because they have a causal effect in mind, and mind has a connection to its physical root, the brain and from there to a body. From our perspective within time we cannot and never will be able to answer this question. First we cannot even access personality directly and second, even if we could, the mystery of how God does such things understandably resides with God. The universe is highly accessible to our collective minds, but there is no guarantee that every mystery is accessible.

The second objection builds on elements of the first and extends them in its own way. The “luck problem” is so called because scientists (and most philosophers) recognize only one exception to determinism, that being quantum randomness. Since randomness cannot be purposeful, if randomness has anything to do with choice, then the outcome (of choice) can only come down to luck. I have dealt with the physicalist aspect of this objection above, but there is another. Imagine a possible world in which there exists a doppelganger of you, exactly the same as you in every respect except at the moment of some decision she makes a choice different from yours. The problem here is that the “same you” made different choices under identical situations so it makes no sense to say that you, qua agent, determined one choice over another. Which choices you make still comes out to luck when considering all possible worlds containing you.

There are two broad ways to conceive “possible worlds”. One is to think of them as merely heuristic devices for exploring truth conditions in counterfactual arguments, and the other is to hold that they are real ontological entities. From a theological viewpoint either comes out to the same argument for the following reasons. If possible worlds are heuristic only then only the real world matters and there is one unified and infinite God. If possible worlds are real, then there can still only be one unqualified infinity (God) in the universe of all possible worlds.

Since God bestows personality, patterns consciousness with it, he cannot create two personalities between which he cannot distinguish. Since each personality is patterned on a separate mind (and God is related to each individually), God must be able to distinguish between them. That means no two persons in the universe can be “the same person”, that is identical to God’s eyes, and this across all possible worlds. A possible world containing a person who (indistinguishably even to God) is also you is logically impossible. Such a world would be, like a possible world containing a square circle, an “impossible world”.

In possible world talk, something is necessary if it is true in all possible worlds, and contingent if true in only some of them. Something is impossible if it is true in none of them, or true only in impossible worlds which comes out to the same thing; impossible. The luck objection is answered because that person in the other possible world, though she shares your history up to the moment of this particular decision, is nevertheless not you; she is a different person and hence can make a different choice for her purposes. Two different people making different choices do not raise the luck problem. The decision in your world is your decision and in the other world it is hers.

The third broad objection to libertarian agency is incoherence. As with the first charge, this one too comes out to begging the question. An action, random, determined, or volitional, is conceived as an event while the agent who is the event’s “original cause” is conceived as substance, albeit non-material. Since physics holds that events unfold (not cause) into subsequent events, how does the substance, exactly, become a prior-determiner of an event when it is not itself an event? A second component of this objection is temporal in character. Events occur at specific times but the agent is extended in time. If there is literally nothing other than the agent’s volition that determines subsequent events how is it that the event happened at some specific time? Why that time and not a little earlier or later? How is it, in other words, that a temporally extended substance that is not itself an event can bring about an event at a specific time? Put another way, how does an extended substance that is not an event interact with time and events?

I want to note first that the notion of “causal agent” as substance and “event” are not so far apart. E. J. Lowe in his “Personal Agency” (2008), demonstrates that any talk of “events unfolding into other events” can be easily cast back into substance-causal terms. Lowe suggests that all cause is “agent cause” but some (most) agents happen to be inannimate. An example can be taken from Lemos’ book. I thrust a red-hot iron rod into a bucket of cold water. The water (substance) causes the iron to cool down, while the iron (substance) causes the water to heat up. Lemos points out that what is really going on here is that events in the iron, the rapid motion of iron atoms, are unfolding into subsequent events as their kinetic energy is transferred to the slower moving molecules of water. What Lemos fails to note, and Lowe points out, is that it is just as reasonable to conceive of the atoms in the iron and the molecules of water as agents. They are not animate agents, and no psychology, consciousness (panpsychism) is imputed to them, but they are agents of the effect, kinetic energy transferred from the iron atoms to the water molecules. Some specific kinetic energy is a temporary property of the atom-agents. Any event description can be transcribed into an agent description, at least as concerns physical process.

Simalarly, persons can be cast as “extended events”. Given the human capacity for abstraction, this is not at all uncommon usage. A galaxy comes into existence and eventually, after hundreds of billions of years, passes out of existence, at least as an identifiable galaxy. Certainly a galaxy can be cast in substance terms, it is an agent for example when its deeper gravity well steals gas from a smaller neighboring galaxy. But it is also a process, an event, the galaxy’s temporal worm whose existence spans some interval.

That we can take what are commonly thought to be substances like galaxies and view them as extended events is not new. This is, after all, what process philosophy is about. By itself, this doesn’t resolve the problem of luck however. In a galaxy after all, when specific events occur is either determined or random. We can refer to measurable antecedent events to explain the timing. Although a person can be cast as an extended event the view doesn’t help us here. As concerns the agent-causal view, there remains nothing about the qualities of the temporally extended person-event other than agent volition enact-able at specific times also determined by the agent. Lowe would probably be uncomfortable casting persons as events and to be sure it is an awkward view in this case. Unlike an atom or a rock animation makes a difference. Either view works easily enough when the agent has no libertarian free will, or indeed any will at all. A substance-agency, becomes more appropriate precisely when the evocation of an event at a specific time is neither random nor determined other than by the agent because only then is it genuinely original cause and not merely events unfolding into other events.

So the question of the coherence of agency here turns on whether there is anything (in the universe) other than “other events” (random or deterministic) that can purposefully initiate events at a specific time that are neither sufficiently determined (by antecedent influences) or random. The agent-causal claim is at root the claim that a libertarian-endowed agent has precisely that power. Put conversely, the power, on the part of an extended (in time) agent, to trigger events at specific points in time determined by the agent’s purposes alone (and of course her skill manipulating her body to bring about the desired event) is one of the qualities (at least) that makes that power libertarian! The capacity, to be original cause at particular moments in time, moments elected by our temporally extended agency, is at the very core of what it means to have a libertarian type of freedom. That this should be is not a mystery theologically speaking because human freedom in time is a derivative of God’s freedom outside time, a derivative God himself bestows upon us.

In God, freedom is absolute, unconstrained (except by logic), and acts across all time. Human freedom is not absolute nor unconstrained. Indeed part of the timing issue can be understood in terms of conditioning influences, the history and present environment, in which the agent finds herself. More importantly, the capacity to initiate an original causal chain, to be an original cause, at a particular moment in time, is how God’s unconstrained freedom comes out in human beings altogether limited to the temporal world. Far from incoherent, this capacity is the essence of the libertarian claim. The coherence of this claim can be in doubt only if God does not exist, but that begs the question because if God does exist it is well within his capacity (not being a logical contradiction) to bestow that very power on personal agents.

The incoherence charge begs its own question because it presupposes the inconceivability of that quality in the agent, the power to originate events without sufficient antecedent cause, that the agent-causal libertarian maintains is in fact a special power of such agents alone. Agent-causal advocates do not deny that this power is not to be found anywhere else in the universe other than in [some] animate agents. To our knowledge (that is human knowledge on Earth) only persons are fully free (a fullness that remains, nevertheless, highly constrained in timespace) in a libertarian sense. The higher animals sometimes appear to exercise choice in ways that suggest they have some similar agent-properties, but I am not sure if in the animal case, the seeming libertarianism of the act is not imputed to them by us.

All three types of objections to agent-causality fail if God is real. The first objection fails because the nature of personal agency, the person being non-material, lies outside science’s domain. The second fails because if “possible worlds” are real, then persons must, nevertheless, remain unique across all possible worlds, and if they are not real, then only the actual world matters and no two persons can be absolutely identical. A person identical to you can only exist in impossible worlds. Two people who are the same person are a logical contradiction. The third objection fails because the very power, of a non-event to initiate an event at a specific time, declared incoherent under an event-only view of causation, is the power of agency given to personality by God. Even if physicists are right about causality being nothing more than the unfolding of events into subsequent events, personality is the exception to that rule in the universe. The exception is possible, conceivable, and not incoherent, precisely because God makes it possible.

God’s existence is a highly prejudicial matter with most scientists and philosophers today. One of the more general problems they have with the agent-causal view is that it so easily slides into dualism and from there to substance-dualism and God. In Lemos’ book, one of his characters (the book is written in the form of a dialogue) notes the association between the view and dualism of one form or another. From a theological perspective, substance dualism grounded in God is suggested precisely because it is a solution to the three objections discussed above. I have argued in many essays collected on this blog and books, that free will, our experience of it, and its conflict with physics, is one of the major reasons for evaluating the explanatory power of dualism. My answers to the objections noted in Lemos’ book flow from what I take to be consequences of God’s existence. Moreover, and this is perhaps the main point to contemporary scientists and philosophers, they justify and warrant our belief in the reality of what seems to our experience to be a genuinely libertarian free will at least as concerns some of our decisions. Agent-cause grounded through personal-agency in turn metaphysically grounded in God explains our seeming freedom the way we actually experience it! None of the other alternatives seem fully to encompass that feat.

Critique of Sean Carroll’s “The Big Picture”

blackhatlong

Sean Carroll has written a book, “The Big Picture, On the Origins of Life, Meaning, and the Universe Itself“. In it, he weaves two themes together. The first theme is that everything in the universe from stars and galaxies evolved to human consciousness, meanings, and values is rooted in a process of emergence that is, in turn, grounded exclusively in what he calls the “core theory” (quantum field theory plus the “standard model” of contemporary particle physics), the second law of thermodynamics, and the “past hypothesis” (the early universe was in a very low-entropy state). The second theme is simply that no other theory, in particular that there is a God and our experience of the universe is partly a product of his designs, is at all reasonable because it is highly unlikely. My short Amazon review of Carroll’s book is here. This essay is a more detailed critique of his approach to that second theme.

Throughout the book Dr. Carroll makes much of “Bayesian inference“, a process by which one comes to refine probability assessments. If, for example, I ask you what is the “prior probability” of a fair coin coming up heads on a single toss, you would naturally say 50%. Now you flip the coin and it comes up tails. The question here is “is the coin fair”. You are asked, given your new data, to reassess your estimate of “prior probability”. One throw is not going to make a difference. If I throw the coin 10 times and it comes up tails 7 of them then what? Seven tails is not all that unlikely even given a fair coin. If after 1000 throws the coin comes up tails 699 times, you think that 50% prior probability was wrong and indeed the coin is not fair. This sort of reassessment works because we can count events. We can compare what we count with what we think should happen and reevaluate our original position. Carroll applies Bayesian reasoning to God, to the probability that he exists. What, exactly, is he counting here? Not events certainly.

Actually, he isn’t counting anything. He offers assertions made about God alongside various philosophical challenges already prejudged to count for or against the likelihood of God’s existence. These aren’t data exactly, but assertions about the world, some sensible and some not. Their sensibility is nowhere independently evaluated, nowhere placed into any context that might change how we think they count for or against God.

Dr. Carroll is too casual about what counts and in what direction it counts. Most of his examples are negative, Hume’s “argument from evil” and the historical fact of there being many different views of God for example. “Why not make himself plain” asks Carroll? That there are reasonable answers to those questions besides God’s non-existence he does not mention. He does adduce a few pieces of evidence in God’s favor, for example the fact that every people comes up with some sort of view of him even if it varies greatly from culture to culture. But his sympathies clearly lie on the negative side here. With regard to Hume’s “argument from evil”, he does allude to the matter of “free will”. He speculates that it might be important to God (though not to us apparently) but fails to appreciate its potential as a part of a full explanation (perspective in this case) in much of what he counts against God’s likelihood. As it happens, free will turns out to be a lynch pin issue for Carroll’s view.

Dr. Carroll is a materialist. He warns us constantly to be alert to cognitive bias, but fails to appreciate his own. He believes that if a phenomenon cannot be measured (at least in potential) by physical instruments ending in our sensory experience, that is intersubjectively by third parties, then it cannot be real. His argument for this is not merely that we don’t find anything but the physical with physical instruments, but what we do find actually explains everything (at least in potential) and so there remains no room for anything other than the physical. Even if such an other were to exist, it has no impact, no physically measurable interaction, with the physical! Why then would we need to posit it?

How did Carroll get here? He tells the story of being a little boy and wanting very much to project causal power directly from his mind to objects lying outside him. He wanted to “bend spoons”. What boy doesn’t? After a while he realized that this is just not something humans are given to do. But he mistakenly concludes (eventually) that if our mind’s cannot bend spoons then they cannot affect any change in any material reality. Coupled with this assumption is Carroll’s affinity for the present view in physics that there aren’t strictly causes in the universe. Of course it is perfectly reasonable for us to talk of cause, a convenient fiction, but really all that is going on in the physical world is the evolution of physical states, this being a natural product of time and the thermodynamic arc from a low entropy past to a high entropy future.

At that point in his life however his materialistic leanings must have been well formed because he missed one obvious alternative; that mind does in fact affect the disposition of matter-energy in exactly one place, in the functioning brains of creatures advanced enough to be conscious! He ultimately justifies his rejection by declaring that nothing of such an influence can be measured. That part is true, we can (as in quantum “virtual transactions” with which Carroll is comfortable) only measure their effects, in this case the subsequent behavior of a body.

We can measure all sorts of goings-on in the brain and we have done an amazing job of tying subjective states to certain kinds of brain-state correlations. But there is no guarantee that in all that we detect, some part of it, some part of what we do in fact measure, is actually caused by something non-material. All we see is physical activity and correlations. If some small part of the complex resonances of the brain were influenced by something that was not in fact material, how would we ever tell? Late in the book, in his chapter on free will, Carroll denies that libertarian free will is even possible precisely because if it was it would entail that some non-material entity made a difference to some material phenomenon. This is a crucial juncture for Carroll’s thought. If there is even one place in which a non-material entity (like a mind) has an influence on the physical world then that influence would be a genuine cause, not merely an evolution from a prior state because that trigger (’cause’ being a good name for it) is not fully determined by any prior state of the universe. This is why libertarian free will is the fulcrum on which Carroll’s whole argument hangs. If he is right and all states of the universe are evolutions from prior states, then libertarian freedom is impossible. But if libertarian free will is real, if we can be uncaused causes, then physics cannot be the ultimate explanation of everything. In particular there has to be something, at least in one place, where as he puts it, “ideas cause physics”.

Why should we, that is physics, accept that there is “one place” in the universe where genuine cause exists? We do not find it anywhere else, why should we believe it happens in relation to the behavior of our bodies? We cannot bend spoons with our mind, why should we think that our minds have an antecedent causal relation with the material entity we call our brain and from there (uncontroversially enough) our body? I can’t bend spoons by staring at them, but I can grab them in my hands and bend them. Why should physics accept that subjective mind is an effective cause in the latter case and not the former? The reason is simple enough, because it is the one place in the universe that we seem to experience it! We experience ourselves being causes, even original causes via control of a body and only via that mechanism. Perhaps this is illusion? Indeed this is entailed by Carroll’s claim that libertarian free will is impossible. But as we look around us in the world and ask from where, if anywhere, new causal chains seem to emerge, the answer is plain, from people.

Carroll asks, if God is so important (as most religions claim he is) then why isn’t his activity in the universe more obvious? Why are we able to tell the complete story of cosmic evolution in physical terms without seeming to leave anything out? Here he is being a bit disingenuous. There is one place, one source, through which God’s influence can be discerned, in the behavior of people, the only locus of genuine original cause in the physical universe. Carroll certainly would ask “where besides people”, and the answer is “nowhere else besides people”! Only people have libertarian free will and it is only by exercise (and by certain exercises and not others) of this will that God influences the world. Why God set things up this way is another question dealt with at length in my books. The issue as concerns Carroll is that he misses the possibility that God did indeed set things up this way, and in so doing renders original cause in the physical (our choice to act ends after all with a behavior of a physical body) compatible with a causeless physics.

Free will is the crux of the answer to the question of why God doesn’t “make himself plain” as Carroll puts it. Doing so would abridge exactly that power, libertarian free will, whose exercise does (loving one another) or does not (killing on another) incrementally bring the world into alignment with God’s desire to evolve a physical universe transformed from a pure competition for survival to one of universal loving cooperation. Done in this way, in the end, a physical universe of love comes about through the free willed choice and not coercion of genuinely independent minds. The combination of purposeless physical mechanism, libertarian free will, and perception of values (truth, beauty, and goodness) in mind go together. God (should he exist) has to be capable of direct and personal action in the physical. Perhaps he does this on occasion, but such occasions are either beneath our notice (see below on life), or very rare, enough so that we can effectively discount their effect in the day by day unfolding of physical process.

Certainly we do not detect the “influence of God” in much of human behavior. But it doesn’t have to be detected in every act. It is enough if it is present even sometimes. What would “the influence of God” look like? Suppose I act to do some kindness, some good, to a person I have every reason to hate. I do this good (let us suppose) for no other reason than that I believe he, like me, is a “child of God”. That sort of decision, taken freely, results in the sort of action that infuses God’s spirit (however much or little of it) into the world. That is what it would look like, people doing good and especially so when they would seem to have every reason to do the opposite.

Because our subjective minds are the one place in the universe over which some non-material entity has some antecedent causal control, the behavior of our bodies, also connected to those minds, are the material locus of novel causal chains. Of course not all of these chains need originate in an attempt to infuse the world with God’s spirit. It is enough that some do! It is also not necessary that any intellectual belief in God (as in the example above) underlie the act. It is enough that the act reflects some one or more of the values truth, beauty, or goodness. Every act of kindness, of unselfishness, of reverence for truth, or creation of beauty, is part of the process of infusing God’s spirit into the world. God doesn’t “make himself plain” precisely so that such acts fully and freely belong to us.

What about a believer who says “God ordered me to kill that man”, or “God has ordered that all heretics be put to the sword”. Put plainly, such declarations are false, lies, and for two reasons. First because the values, God’s spirit detected by our minds, are truth, beauty, and goodness. Killing might sometimes be necessary for material reasons (self defense for example) but it cannot ever reflect the “will of God”. No act that does not reflect one of more of the values results in a behavior that infuses God’s spirit into the world. Second, God doesn’t order anyone to do anything good or evil. That is what free will is for. God provides only spiritual pointers. A decision to do anything with or about them, positive or negative, is entirely up to us.

The general thrust of Carroll’s argument is that what physics has discovered about the universe must be true. This doesn’t mean the discoveries are the complete story of everything by any means. What he means here is that they must be a part of the truth and indeed a major part as concerns the cosmos over all. He notes that we live in a universe that, in its deep past, had a very low-entropy. Whether or not this was the literal beginning of our universe of some stage of a longer process he, and we, do not know, but at some point in the past entropy was very low. Thanks to this beginning, combined with the forces of the “core theory”, and the fact that the universe is not yet in thermodynamic equilibrium, we live in an age of developing complexity. From Carroll’s viewpoint, everything from the gathering of primordial particles into atoms, stars, and galaxies, to the appearance of life, consciousness, and love, is all merely the physical evolution of contingent (it might have happened otherwise) complexity thanks to the potentials made possible by the settings and regularities (laws) coupled with that moment in cosmological history in between a very low entropy beginning and a very high entropy future.

I have no doubt that the physical complexity we find around us, from stars to other people, even our own brains hangs on exactly what Dr. Carroll claims here. That is, the thermodynamic arc, coupled with the core theory not only allows for all of these possibilities, but also that they are indeed physically constructed (emerge) from them. Carroll is not alone here, a number of recent books, including one of my own, builds on the phenomenon of emergence.

In building complexity Carroll notes that, from our viewpoint, as the evolution of the physical results in information being compounded upon information we find value in describing phenomena at different levels. There are many examples of this. His favorite (an uncontroversial example, another being the relation between Newtonian mechanics and General Relativity he also mentions) is the language of “gas laws” (temperature and pressure) to describe the same phenomenon as are described at the level of individual molecules with “statistical mechanics”. Same phenomenon, different languages.

In truth, this transformation of viewpoints does carry all the way up from physics to chemistry, biology, and even sociology. The reason such language transformations work in these cases is precisely because we are able, as observers, to measure these phenomena! As we study the behavior of social systems (or gasses), we are able to measure what the people (or molecules) physically do, where the money (in paper or bits) flows, how ideas are exchanged. All of this has to do with observable (measurable) behavior. In fact, as I noted above, it is in observing the behavior of persons, assuming libertarian free will to be genuine, that we sometimes (if we know what we are looking for) detect the influence of God in the physical universe.

But Dr. Carroll confidently asserts that the same phenomenon is going on, that is, what we have is nothing more than an “alternative language”, as concerns such subjective phenomena as feelings, thoughts, qualia, and decisions. He insists, that these are “nothing more than ways of talking” about physical phenomena that can be measured (at least in potential), and that once we have actually measured all of them we will discover that there is nothing else to be said about subjective experience. He insists that one day we will, from a third-party perspective as observers, be able to explain ourselves in the same way that we connect up statistical mechanics to the gas laws and Newton with Einstein.

Plainly there is a difference here, a difference of which Carroll must be aware. Unlike the phenomena described by Boltzman or Einstein, we are not third party observers of subjective experience. By definition it is individual, subjective, available only in the first person. What makes our internal states different from such things as the gas laws is that they cannot be intersubjectively quantified. They can’t be measured by third parties. Of course we can measure the obviously physical phenomenon that underlie their appearance, the functioning brain, but we can never “connect up” a pain quale or a belief with a neural event in the same way as we can connect individual molecules with their average collective behavior because we cannot measure the other [subjective] side.

Solipcism (the notion that I alone am real or genuinely conscious and everyone else is some part of my dream), isn’t much taken seriously, but that we can entertain the notion and that we do not find it obviously incoherent demonstrates the uniqueness of our subjectivity, its inaccessibility from the outside. We can find correlations between neurons and subjective content, but we can never be sure that subjective content is “nothing more” than neurons because we can’t quantify the gap. We can measure that more C-fiber firing correlates with more intense pain, but we cannot show why chemicals spewing across a synapse should manifest as the subjective quality of pain.

In a later part of the book, Carroll declares that, like libertarian free will, there can be no such thing as post-mortal existence. He says there is nothing in physics, in the core theory or anything we observe to support this idea. Of course he is correct. There is nothing in physics to suggest any such a thing is possible, but the claim as concerns such survival has nought (usually) to do with physics. True, there are doctrines that say our bodies are ressurected. Those doctrines are, to put it bluntly, wrong. If anything survives mortal death it isn’t a physical entity. How the survival mechanism might go, I address in another essay. But whatever the mechanism, it has nothing to do with physics. Carroll claims there is nothing in physics that supports any concept of a post-mortal life. Limited to the idea of a physical post-mortal survival he is right. But he isn’t addressing the real issue which is the possibility of a non-physical survival mechanism. Science has no business being anything but neutral on this matter.

Carroll here isn’t content merely to claim that a post-mortal experience is impossible. He derides it with a story of a man who, upon dying, goes to heaven and decides to spend his days endlessly having sex, eating, and playing golf. Eventually the man grows bored and begins to contemplate suicide. Carroll’s story, meant to be humorous, is akin to a kindergardner who, having been told that her career aspirations will require another 20+ years of school, imagines that those 20 years will be filled with finger painting, naps, and story-time! Really Dr. Carroll? You are far past kindergarden and you cannot think of anything more adventurous and compelling as concerns growth toward perfection than more of the same, more finger painting, naps and story time? You could not imagine something more robust? Does death alone perfect us in God’s eyes?

In another shot at a straw man, Carroll asks, if God created us, a single planet populated by creatures that can (rightly or wrongly) contemplate him, why go on to create the rest of the physical universe of billions and billions of galaxies? The rejoinder here seems pretty obvious. The doctrine that we are alone in the universe, alone “created in God’s image” is, like the notion of a resurrected body above, simply wrong, another 2000 year-old notion whose time is long past. The universe is, or will be, inhabited. To be sure I am not speaking of every rock being populated, but billions of rocks have conditions suitable for life even as we understand it. Given that God seems to be intent on making over the universe based on the free will choices of suitable creatures, all of those rocks, if they are not already inhabited by personal beings (whatever their physiology) are evolving in that direction! This speculation leads to some testable predictions.

Let us say, broadly speaking, that there are three general mechanisms by which life appeared in the universe. The first is simply random accidental association, what most scientists on Earth today believe. That this is highly unlikely, but nevertheless possible (that is physically possible) is granted. Secondly, supposing God exists, perhaps he arranged things at the beginning of the universe such that life would not only be possible, but likely to arise in all (or most) more-or-less supporting environments. The assembly of life remains, in this view, strictly accidental, but now more of “an accident waiting to happen”, a not-uncommon accident once certain environmental conditions are met; conditions found in many places throughout the universe. This view is suggested by notions like the “anomalous monism” of Donald Davidson and Thomas Nagel, or panpsychism from David Chalmers. Carroll would undoubtedly note (and I would agree with him) that there is no evidence in physics for either of these views. The third possibility is that God (directly or indirectly) has a hand in initiating life (which evolves by Darwinian mechanism from that point forward) on each life bearing world.

In the first scenario, we expect life to be very rare. Of the billions and billions of potentially inhabitable worlds only a very few would exhibit life at all, and even fewer a life that advances to consciousness. We might also find once-living-now-dead worlds where life managed to begin but was snuffed out as environmental conditions evolved unfavorably. Mostly, however, we would expect to find no life present or past on most worlds.

The second scenario results in a much different outcome. Life would be everywhere (or nearly) in every supporting environment. We would also expect to find many once-living-now-dead worlds because life starts itself easily when conditions are right, even if they are not destined to remain so. Mars is a seminal possibility here. It is widely believed that the Martian environment was once life-supporting, but evolved away from that state. If this second scenario is true, then we would expect to find evidence of ancient and extinct past life on Mars. We would also expect, since God had a hand in this scenario, that any planet whose conditions were such as to support highly complex and conscious life would eventually do so. We might stumble on such a world in a primitive age prior to the evolution of complex forms, but if we could follow the planet for a few billion years and its geophysical evolution continued to be supportive, we would expect conscious life to evolve.

In the last scenario we would expect something very different again. We would expect either that a world is dead, having no present or past life if the present environment is not life supporting, or the world has life and both the physical conditions and that life always evolves to consciousness. On every world where life is to be found, consciousness follows eventually. Why? Because God “knows the end from the beginning”. Why would he initiate life on a world (for example Mars) that was destined to lose the capacity to support it? If God starts life on a world, he would know that world will evolve geophysically in parallel with biological evolution and eventually come to support complex (and conscious) life. This is not to say that every living world has at this time evolved complex life, but under this scenario, it will.

Even given the second or third scenarios above, there is no guarantee, indeed it remains highly unlikely, that we will ever be able to detect such life across light years of space. There are too many variables, and at least one of them, is not even on the minds of astronomers and astrobiologists. Why, if life is started where it has the potential to become conscious, have we not yet found evidence of it? There are three broad possibilities.

1. Life on the remote world has not reached an electronic stage or is not industrialized in a way that leaves detectable pollutant traces in its atmosphere.
2. Life on the remote world has reached an advanced and electronic stage but we cannot detect it because: (a) it is far away and the signals haven’t reached us yet, or (b) the signals, having reached us are just too weak to distinguish from any background.
3. Life on the remote world has reached an advanced stage, but it is not and will never become electronic.

The last is a distinction to which scientists and philosophers alike seem oblivious. They assume that “advanced life” is necessarily concomitant with industrialization and electronic signalling; a very provincial assumption. From God’s viewpoint an “advanced civilization” would be one in which all or most people freely choose to attempt to do his will, to love others and be generally successful in the attempt. It would be a world that has (among other things) long relegated such phenomena as war, bigotry, and crime to its distant past. There is nothing about this sort of advancement that entails electronics. I discuss this at some length in my first book, but the bottom line is that there is nothing about Earth’s particular historical path that suggests anything similar is implied by the notion of “advanced civilization” on other worlds.

I hope I am not being unfair to Dr. Carroll. He has contemporaries in the scientific community who become apoplectic at the mention of God. Carroll does not become apoplectic. He tries to make room for such a possibility while rejecting it as “highly unlikely”. He is brave enough, and does manage, to put his finger on the crux of the matter. If libertarian free will is real, then physics must be incomplete. By itself this wouldn’t prove that God exists, but it would, in Bayesian terms, set his prior-probability very high. Rather than accepting that libertarian free will is real, the evidence being our subjective experience of it, his cognitive bias leads him to reject it, essentially denying what must be his own experience. He is far from alone in this. To me there is considerable irony in scientists and philosophers (ordinary folks mostly don’t think about it) freely denying their freedom.

Carroll has a very nice website and blog. I have tried on occasion to engage him as concerns these matters, but he has been disinclined to respond. His cognitive bias is, after all, very strong. If there is a discussion of his book on his blog I will let him know about this critique in a comment. I don’t imagine I will hear from him, but I am open to being surprised.

What is “the Soul”?

blackhatsmirk

In all the other essays in this blog, as controversial as they might be, I could at least argue from some part of the content of our experience. Whether or not libertarian free will is real (or even possible) can be debated, but most people at least do admit that it seems like it is real and that we exercise it. The same is true of values: truth, beauty, and goodness. Are they illusions? Do we make them up, deliberately invent them? Perhaps we really detect their presence, they are real and stem from the same source as consciousness itself.

When it comes to the soul, however, we are at a loss. Simply put we experience nothing what-so-ever of our soul. Now philosophers of religion and theologians will perhaps disagree with me here, but their world is quite mixed up as concerns the soul. Mostly they use it as a word to mean just about anything they want having some bearing on what they take to be our “experiential core”. ‘Soul’ has been used as a synonym for ‘essence’, ‘personality’, ‘mind’, and any combination of any of them even including the body. I do not believe the soul is any of these things. To put it bluntly, we do not experience anything of the soul.

If we do not experience it, why should I think there is a soul at all? The answer has to do with the conviction that God, if he exists, must be both infinite, good, and the source of personality. If “God’s purpose” has to do with personality’s progressive alignment with the “will of God” as described in my first and third books, and more briefly my blog essay “Why Free Will”, then it doesn’t make sense if, on material death, the personality simply vanishes from the universe never again to be expressed. If we are supposed, progressively, to become perfect, like God, in a spiritual sense, this process certainly is not completed by the end of a very short (in cosmic terms) mortal life. What is the point of the fixed temporal reference of personality (see “Why Personality”), of all that we acquire, if it vanishes after a few score years on Earth?

If all this process has a point then personality must somehow survive mortal death. When we die our brain-based consciousness is obliterated, but not the information, the pattern configured into it by God. There is no consciousness here, something that we might best relate to having surgery under general anesthetic. In that case, consciousness (along with its configuring personality) is placed into a deep sleep. With no consciousness in which to operate, personality simply ceases to experience anything, and that includes the passage of time. But as our brain-based consciousness returns to wakefulness, the personality is again expressed.

The inference that there must be a soul if God is real is one of the “consequences of Infinity” I discuss at length in my books and here in “Prolegomena to a Future Theology”. In this case, a consequence that lies strictly beyond our subjective experience. Unlike personality, whose direct apprehension skirts the edge of our self-consciousness and must be present to explain, for example, recursive self-consciousness, the soul doesn’t have to be there at all as far as we, that is our personal selves on Earth are concerned. In short, it has nothing to do with our mortal lives.

Following material death consciousness ceases, but after some unknown duration we wake up again. The person emerges in association again with mind, that is, a consciousness produced by contact with Cosmic Mind (see “From What Comes Mind”). There is also, I presume, some vehicle of expression, something analogous to a body recognized by other persons as the locus of the individuality that is our-self. The vehicle isn’t material by our present reconning but it can be seen and identified by the expanded perceptual systems of its own type. Other post-mortal persons can see and discriminate one another from some environment. In this new case, the mind isn’t brain-based, but rests on something not material, not measurable by physical instruments, and within a vehicle with which the new person-mind combination can express itself. What kind of stuff is that? Is it the same “spirit stuff” of which God is made? I do not know and as we cannot detect it, we cannot say much about it. But if non-material reality actually is real, a part of the Universe’s fundamental ontology, there can be any number of levels or layers or types of “non-material stuff” between God and the material world with which we are familiar.

So we have “the person” and we have a consciousness (likely greatly expanded over our present matter-based version), and a vehicle of expression, but so far no memories. As I noted in my “Why Personality” essay the person has no purchase on its identity without memories which, in our case, are brain-based and so vanish when we die. This, I believe is where the soul comes into the picture. It is, if you will pardon the metaphor, the lifeboat, the escape mechanism that retains memory of the mortal existence. Memories with which we are re-associated when we “wake up”.

What memories? All of them? In our present estate the soul must evolve, grow, along with us even if we experience nothing of it. It is something like a baby within us albeit a baby we do not experience. Possibly it contains all of our memories, God must remember them after all, but I do not think so. Human life is filled with experiences of no spiritual value, that is no bearing on the free willed choice to “do God’s Will”. Experience of physical pleasures are obvious examples, but there are many others. What does have bearing on our future, what is of “spiritual value” are the experiences we have as result of instantiating (or attempting instantiation) of one or more of the values (see “What are Truth, Beauty, and Goodness?”) the only “stuff of spirit” with which we, with our brain-based minds, have contact. I hypothesize (and this is purely a speculation) that the memories we retain and wake-up with are the instances of value choice we make during our mortal life. Every time we make a positive spiritual choice, a choice to fit or instantiate some value into the world (more precisely to attempt that instantiation since we are not always successful and often only partly successful) that choice is recorded in the soul.

If true, this has interesting consequences. Notice in describing this mechanism I have said nothing about any intellectual belief in the reality of God. Atheists and theists alike make “spiritual decisions”, choices based on and for “reasons of” truth, beauty, goodness, or some combination of them. We commonly relate these to “the moral” and choosing “the moral” in any given instance has nothing directly to do with the intellectual baggage carried by the choosing individual. It might seem that “a believer” has more reason to make value-laden decisions than “an unbeliever”, but this is only theoretical. There are, in real life, many atheists who make more of these decisions than many theists. All of them have a soul.

Suppose we take two normal people (atheists or theists it doesn’t matter). One of them makes some value-instantiating decision on average every day of her life, at least those in which she was aware of herself and values. Lets say she had 50 years of such experience since becoming “self-aware” and before she dies or dementia degrades her brain enough to destroy her sensitivity to values. Our other person, on average, makes only one value entangled choice once every month over the same 50 years.

Upon waking in the post-mortal life our first candidate will retain some memory of every day of those 50 years, more than 18,000 memories. Even those she has forgotten in the mortal life will be available to her. By contrast our second candidate will have memories of 600 days of his previous life. Our two candidate’s status, as concerns personality, consciousness, and expressive vehicle when they wake is the same. But one of them retains far more memories of her prior experience (even if she was an atheist and never attended a church in her life) than the other even if he believed in God and attended church every week! To the extent that “going to church” motivates you to make more spiritual decisions the experience is of value. If it does not then, as with what you believe about God, it makes no difference what-so-ever.

Although this is the variation that recommends living a better, more value-entangled, life on Earth, I do not know how much of a difference it makes in the end. Like two siblings born 3 or 4 years apart, the difference in ages makes a considerable difference in their comprehension of the world for a few years, but by the time 30 or more years have elapsed the age difference is washed out. This is the meaning, I believe of Jesus’ parable of the harvest. Everyone gets the same thing in the end. Even a 75 year life on Earth is but 28,000 days. It might take trillions of days measured in Earth-time to reach some provisional end to the process of “becoming perfect as God is perfect”, more than enough time to obliterate the difference of a few thousand memories. But in the early times of the post-mortal career, there will be a difference. Our first candidate will advance in the program more quickly than the second.

I would make two quick observations before ending this. First philosophers have debated the nature of such identity transfers or duplication. Usually these are cast in terms of clones or star-trek-like transporters, but the notion has been applied to God. Does God move the person (and/or soul) from Earth to somewhere else, or does he use his omnipotence and perfect memory simply to recreate them? While such thought experiments are indeed puzzling as concerns clones or transporters they amount to a difference that makes no difference as concerns God. God is not subject to the second law of thermodynamics. Either way, the resulting copy, if that is what it is, is perfect, suffering no degradation whatsoever. From the subjective view of the individual no difference could be discerned. Either way, we will wake up aware that we are the same person who lived another life in another place and that the memories we find in the contents of our new consciousness belong to that person, us.

Second there inevitably arises the question of soul death. Can a soul die? Since it is non-material I do not think it can suffer death by accident or be murdered. But if free will is genuine, we must be able to commit suicide, to choose not to continue in the post-mortal adventure. Suicide of this sort is probably very rare if it ever happens at all in the post-mortal experience, but it must be possible if we are genuinely free. There is nothing to suggest that the post-mortal experience is timeless, the soul is not immortal in an unqualified way. On the other hand, I am not sure simple cosmic-suicide is possible on Earth. We can kill our body, but in that case the automatic life-boat mechanism kicks in and that person/soul combination survives having developed up to the point of physical suicide. In the next life, we begin where we left off here whether we were 80 or 10!

It might be possible to kill our souls on Earth through consistent, repeated choices of evil, choices in opposition to what is represented by the values. If we are (individually) evil enough, so steeped in evil that we lose the capacity to discern values altogether, we also lose the capacity to know right from wrong, and not just most of the time but always. We become, in short, iniquitous! It is possible (though I do not know) that in such a case our souls can wither and die. From that point on, in the life of that mortal, no survival raft exists and such personality vanishes (perhaps merging back into the infinite as a drop of water merges with the ocean) on physical death. Notice that this suicide entails the repeated exercise of free will choice. A single horrifically evil decision would not seem to be enough to obliterate the soul. Accident or disease, the degradation of the physical brain to the point that value discrimination is no longer possible, might freeze the soul in its present status at that time in the life of the individual, but God well knows that the individual has not chosen this outcome of his or her own will and the survival mechanism remains operative.

My speculative story ends here. I have gone into these things in more detail in my books (the first and third). More importantly it is there connected up with what we do experience of spirit. I emphasize here, in conclusion, that this is nothing but a speculative story based not on direct experience but on inference from basic assumptions about the nature of God and the purpose of experience, in particular the point of free will in a physical universe of purposeless mechanism. I tell this tale because it fills a hole in the theology I describe in my first book. If God’s “perfect universe” takes billions of years to complete, then the short mortal experience, something usually less than 100 years, we have on Earth cannot be the end of the story even though we have no experiential (subjective or otherwise) evidence of this mechanism’s operation.

Why Personality?

selfie

This entire essay is substantially re-written in April 2019 to bring it in line with the evolution of my thinking expressed in more recent work. Additional work in November 2019 better clarifies the connection between mind and information.

I am not merely a dualist, but a tri-ist. Mind is not the only substantive entity in the universe of our experience that isn’t physical. To understand why my ontology makes room for a personality which is in the human (not the animal) case a facet of our selfhood experience, I have to explain what it is about human experience that demands our postulation of it. To do this, I must begin with mind in general and not “personal mind” or “personalized mind”. The higher animals give us what we need here.

Physics alone cannot give us mind though to be sure it is one of mind’s roots (see in particular “From What Comes Mind?” for a general over-view of the model, “Physics and the Evidence for Non-Material Consciousness”, and “Fantasy Physics and the Genesis of Mind”). Over-all the metaphysical ground of my views on this is theistic, specifically a theism sketched here in “Prolegomena to a Future Theology”.  I am not going to go into the theology here, but I must delve a little bit into mind because the point of the essay is to argue that even postulating a substantive (in a quasi-Cartesian sense) mind is not enough to account for human experience. There is something else in addition to mind. That is to say, there are certain experiences that suggest such a thing exists, and this something I call personality.

Mind broadly speaking is purposeful. Animals have purposes for which they engage in their various behaviors. They do not articulate these purposes as such but it is clear that there is a reasonable sense in which higher animals can be said to be both minded (having some content of consciousness) and “act with purpose”. Indeed it can be said that life in general, even non-minded life (say paramecia) act purposefully and indeed they do. But lacking consciousness, it is less reasonable to say that such animals “act volitionally” and more reasonable to say that human beings impute purpose to life in general. Paramecia act, but the purposes of those actions are not the purposes of an individual, as these become in the higher animals. It is consciousness generally that adds both individuality and purposefulness.

But we notice limitations in animal mind that are absent in humans. Animal purposes are always local, limited to the present time. To find food if hungry, reproduce, shelter, even to socialize, all of it for its own sake. Humans by contrast exhibit all of these same sorts of local purposes, but they also exhibit purposes extended in time, purposes for next year, or a lifetime.

Animal do not recursively evaluate their purposes. They do not abstract. A lioness, being hungry, engages in the hunt for food. She decides on the specific course that hunt might take as new data emerges to her senses concerning the presence of food. But she certainly does not deliberate on the purpose of hunting in the abstract. Humans do exactly this. We are said to be “self conscious” and are able therefore to deliberate not only on the process of executing a purpose, but on the purpose itself.

Humans are also creators in a way that animals are not. Apes can modify sticks or other objects to use as tools, but only humans create new tools, even vast engineering projects that are more than mere modification of existing things. There is also the matter of art, social institutions, religion, and abstract-capable language.

It is these qualities that signal something special about human consciousness that needs explaining.  At the same time, I have to explain how it is that we cannot locate this entity in a recursive examination of consciousness. Our self-consciousness does not permit discrimination of the personal from consciousness as a whole, even in the first person!

I follow here briefly with a sketch of my theologically-grounded theory of mind. See above linked articles and  my first book all covering this in more detail. God is the source of the physical universe of spacetime. Into this universe, besides a physics of purposeless mechanism, something I have called “Cosmic Mind” is also added. Cosmic Mind is not a person, but rather a sort of field pervading space and time analogous to an electromagnetic field. Important here is that the field is in space and conditioned by time. It is non-material however. It does not convey any sort of proto-consciousness or panpsychism on the universe, but interacts only with certain complex organizations of matter-energy that we call brains. When nervous systems (of animals) become complex enough they are able to be perturbed or in some manner affected by Cosmic Mind and it is this interaction that manifests subjectively as consciousness.

This is the quasi-Cartesian aspect of my view. It is quasi-Cartesian because mind is not added to brains in Cartesian fashion, but rather emerges from brains, a property dualism, in response to, or because of, the universal presence of Cosmic Mind. Yes, there is an “interaction problem”. As it turns out attempts a purely physical explanations of mind (other than eliminativism) all have variations of the same problem. See the aforementioned “Fantasy Physics” article for much elaboration on this.

The point of Cosmic Mind in the theory (it may have other roles in the universe) is to effect subjective experience in sufficiently evolved nervous systems. Brains are, in effect, detectors of Cosmic Mind and consciousness constitutes that detection. Evolving mind at first detects very little of this signal producing minimal consciousness — perhaps a “what it is like to be” a fish or a lizard. More evolved brains are affected in richer ways and the nature of those individual minds deepens.

When we reach the human level, indeed the definition of humanity from a God’s-eye-view, the brain begins to feel the impact of parts of the Cosmic Mind signal not detected by any other animals. Specifically human brains begin to detect what the Cosmic Mind signal conveys of spirit, the hypothetical stuff of which God is made and the antecedent source of both physics and mind. From the subjective viewpoint, spirit is conveyed in the form of the values, truth, beauty, and goodness. See “What are Truth, Beauty, and Goodness” for further elaboration on these.

The detection of the values by human (and not animal) mind is not an automatic “good judgement” concerning what has values; what is true, good or beautiful. It is the discrimination of their three-part existence. The “spirit component” of the Cosmic Mind signal is always there. It impacts animal mind. But animals do not discriminate it as distinct elements in consciousness. Humans do.

Continuing the theological picture, something else happens when brains and therefore mind reach this level of physical complexity and signal-detecting richness. Such minds are personalized by God directly. In the fashion of Thomistic or Aristotelian Hylomorphic  dualism, God configures each such individual mind with extra information (a form) that becomes fused with that consciousness in such a way that from any perspective (even in the first person) it is not possible to tell what part of subjective consciousness comes from Cosmic Mind alone, and what part from the fused-in personality.

No other mind in the universe, personal or otherwise, can make this discrimination, but it cannot be lost to God. Other minds, including ourselves in the first person are aware only of the combined result, mind simpliciter in the third person, and the content and structure of our own consciousness in the first. God alone knows what was done to each value-discriminating mind to personalize it. To emphasize, the added pattern is not physical. It is a form imposed on immaterial mind itself.

The relation between a value-discriminating mind and a personalized mind is contingent (nothing forces God to immediately personalize every value-discriminating mind) but constant. Value-discriminating minds are all and always personal, they are the minds of persons.

The idea of a substantive personality within the mind is derided in philosophy as a homunculus, a little controller commanding the rest of the conscious arena like the captain of a ship. This model proves to have many philosophical problems, but it is an incorrect model. When a captain steps onto a ship, you have a ship and its captain. The captain is added to the ship and remains distinct. But personality is not added to mind in this sense. Rather mind itself is personalized in the manner of a lump of clay turned into a statue. One does not “add statue to lump”, but rather transforms or forms lump. Once transformed, there is still nothing but a lump of clay albeit in a more structured configuration.

From any viewpoint other than God’s, “personalized mind” is still only mind. Even the individual (the person) whose mind it is cannot segregate itself from the mental arena as a whole that includes it. Even we, subjectively, cannot find personality through self-examination, because as Hume noted all we find are properties of mind. The character of our subjective mind includes personality (the imposed form) but we cannot isolate that inclusion. We do however experience its presence as a part of our mind-personality amalgam, our phenomenal sense-of-self. Our minds are what they are after all, but human mind has capacities that mind alone (animal mind) does not appear to have.

Information

It can be useful to examine mind from an information perspective. In physics, information is another way to express the structure of and relation between physical objects. The more structured, the higher their information content. Information is an inversion of entropy. Stars are information-rich compared to clouds of hydrogen gas, but in the case of stars, the information added comes from nothing more than macroscopic and deterministic behavior described by natural law. Life is far more information-rich than stars and it is not clear all of life’s information assembled itself from nothing beyond the operation of natural law. There are those who quite reasonably suggest (having math to support it) that life’s information is unlikely to have assembled itself accidentally. But this is another subject.

As we move up the evolutionary chain of our biology we encounter artifacts of mind. A beaver dam for example is a configuration of sticks, logs, and other natural products suitable for habitation and young-raising by beavers. We can examine such a dam and quantify the information it contains in its configuration, but it is clear in this case that the specification for that information came from outside. The dam didn’t build itself. One way or another, the specifying information was imposed on the physical ingredients by the labor of beavers. If there is something it is to be like a beaver, then that information, the information to cut and configure the trees, lodges somewhere (from our third-party perspective) in “beaver mind”.

Beaver mind emerges from beaver brains plus its contact with Cosmic Mind. There is no doubt that the structure of brains can be described in information terms. Brains have all the information contained in life and then some. There are those who claim there is nothing more to mind than information coded into brains, but this is controversial. Nevertheless, from stars to life to brains we grasp that information is expressed in physical structure of one kind or another.

On my “Cosmic-Mind-Perturbation” model, can consciousness itself be understood in information terms? The structured perturbations of electrons by an electromagnetic wave in an antenna are information. Whatever goes on in the interaction between Cosmic Mind and brains it is reasonable to suppose that information is involved. If the interaction affects any part of the physical (electro-chemical) resonances of the brain we would expect to be able to measure it, though there is no guarantee we would recognize the significance of what is being measured. In any case, it does seem like the content of consciousness (as distinct from consciousness as such) is information rich. Qualia in particular are often cast in terms of information.

It isn’t as clear that consciousness per se can be cast in information-language.  Information is quantifiable. Subjective experience simpliciter is precisely not quantifiable. Consciousness is an experience of a subject. It’s content is information-rich, but it might be the case that what can quantified of that information is a product of the brain alone. The information content of mind need not be a contribution of Cosmic Mind.

When we come to human mind, personalized mind, there comes to be, necessarily, information in mind itself, in its form not merely its content. Personality if it is conceived as a hylomorphic form on mind can only be information added to mind, structuring the gestalt of the emergent consciousness. But we can only infer this is the case, that human mind includes some directly incorporated information, from qualities we subjectively experience! We cannot ever hope to identify it. Personality is utterly transparent!

Individual mind, even apart from personality is likely unique. Given that no two brains (human or animal) are absolutely identical, no two minds are identical. But personality adds an additional quality of uniqueness, a unique pattern joined with and as that mind.

We can say that personality is an additional configuration on top of mind analogous to the way brains are a configuration on top of life. But even if life origin involved some purposeful addition of information to the universe, life remains self-sustaining from that point forward in time. Consciousness, by contrast (with or without personality) is dynamic and depends on the constant interaction between Cosmic Mind and brains. Mind’s presence (at least in animals on Earth) cannot be maintained in the absence of a properly functioning brain. If the brain fails or becomes functionally distorted in some way, consciousness is impacted and in severe enough cases disappears altogether. If the mind disappears, so does its personal configuration.

The specifics of the addition being a non-material extra-configuration of a non-material entity cannot be measured by any instruments. Any third party distinction is likewise forever out of the question. Even to our view, personality isn’t segregated from mind. God can distinguish it, but we experience nothing other than the mental arena that results from the fusion. From a phenomenological viewpoint it is all “merely mind”, in the same way that a lion’s mind is all merely mind.

Personality is epistemologically transparent in the first person because we cannot distinguish its information as such. We cannot distinguish where mind leaves off and personality begins. Everything that we do and experience as persons, what we subjectively experience to be ourselves, takes place in and through mind, the amalgam of personality and mind-simpliciter. We are forced (discussed further below) to infer that personality must be real and distinct, ontologically, from mind as such, but even the evidence that this inference is valid is experienced only in and through the amalgamation. The reality of personality is a metaphysical inference made with some phenomenal, but not epistemological support. It is to that phenomenal support that I now turn.

The Metaphysical Requirement for Personality

The evidence for our inference comes down to recognizing that human consciousness has qualities that cannot take origin in mind alone. This is the phenomenal evidence that something is going on besides mind. There are three such qualities: self-consciousness, persistence without change in time, and a partially a-temporal free will. The first and last are consequences of the personality’s separation (though we cannot discriminate it) from mind. The second quality is characteristic of personality itself.

— Recursive self-consciousness

Animals experience contents of consciousness and can evaluate those contents. They have limited free will. A lioness can choose between two zebras, one a bit nearer but appearing younger and faster than another somewhat farther away. She is quite able to evaluate both and make a decision (perhaps in error) concerning which is easier to catch. But the lioness is not able to evaluate consciousness as such, she merely accepts its nature and content as given. Only humans are capable of making this second-order evaluation and we are able to make it because our consciousness contains the extra personal information. Although we cannot find that extra information, its presence enables recursive evaluation analogous to the way having two eyes gives us a direct perception of depth in three dimensions.

Self-consciousness is the most uncontroversial of the three qualities personality contributes to consciousness. That is, it is uncontroversial that we, humans at least, are self-conscious. There is some dispute over this matter as concerns some animals, but I believe that these cases constitute a reading-in, an anthropomorphic imputation similar to metaphorical imputation of purpose to simple life. Most of this controversy comes from observation that animals exhibit complex emotions including feelings of compassion, affection, and even awareness of the possibility of other selves when they are not immediately present to the senses. At the same time, there is no direct evidence of self-evaluation.

In humans self-evaluation seems to compel attempts at expression. It is one of the drivers of language development. We see no evidence of a “compulsion for expression” in any animals. Animals who have shown remarkable ability to acquire human languages do not seem to use what they acquire to construct abstract propositions concerning consciousness itself. If an ape, taught to spell English words, in blocks wrote out “is my green the same as your green?” I would have to modify my view here.

If from our viewpoint we cannot discriminate personality from mind what then is contrasting about it to us? Self consciousness is an automatic consequence of amalgamated mind. The signature quality of personality itself is its changelessness. Even Cosmic Mind lies inside time and is subject to it. Mind, our mind’s, change over our lifetimes. Personality, the specific pattern or form amalgamated with a temporal mind never changes.

— Changeless identity

The person of God is changeless absolutely and for all eternity. He (perhaps with his two coordinates in the Trinity) is the only literally changeless entity in the universe.  This needs some elaboration. Persistence in the material universe is not ever absolute. We say that material objects persist even though we recognize that they slowly undergo change over time. Not only material objects, but consciousness too changes with time. The contents change of course, and the overall quality and structure of the arena undergoes change as well. Yet the part of the “personalized mind” recognized by God as the person never changes and this self is but vaguely sensed by the subject as that entity takes and has taken ownership of that conscious life in and through all of the changes it otherwise undergoes.

There is no direct third-party access to subjective consciousness. To phenomenal experience, the person, my “I” is even more private than consciousness. I can to some extent examine my own mind, but even I cannot examine my personality distinct from that mind. Yet the amalgam  does provide a distinct experience that is independent of what does change, our character, that which we express. Character can be measured. It is the expression, the output, of the internal personalized mind acting to control a body, evolving and changing along with everything else in the universe.

Anything about a human being’s behavior or inner state that can be observed or queried (e.g. “personality tests”) comes under character. None of it, internal (a sunny disposition) or external (observable behavior) is personality as I am using that term. Because consciousness (and more obviously the body) changes, character changes.

The persistence of a changeless self throughout the history of that character is even more invisible than the presence of a consciousness behind its expression in character! But the owner of those changes remains the same and is aware of being the same throughout. Despite having traversed many changes in character (and physical characteristics) over the course of our lives we are perfectly aware, under normal circumstances, that the same person owns all of those changes.

In theory, if we had an instrument that could measure, perhaps make graphic, a subjective viewpoint without personality, and then the same individual mind personalized, it would be possible to subtract the first measurement from the second and identify what it is about consciousness that constitutes its personalization. That is, it would be possible to recover the information difference between the two. But there is no such instrument nor can there ever be because the only detector that exists in the universe for this phenomenon is the personalized mind.

There is yet another reason why such a subtraction would not be possible. Human mind, mind capable of detecting value, is always personalized. Value detection (or its potential) appears to be the necessary and sufficient condition for the immediate awarding of personal status. This is another one of the reasons for the phenomenon’s epistemological transparency. We cannot have even a memory of a time when our consciousness was not personalized.

The quality of changelessness has everything to do with our (that is human) relation to time. Humans alone among the animals can project purpose into the future as such or act for the sake of the past. We can do this thanks to a fixed reference available as a temporal background in our experience. There are examples of what appears to be such capacity among the animals; squirrels storing nuts in the fall to eat in the winter come to mind. But I question whether the squirrel is projecting a purposeful self into a future time or merely following biological imperatives at any given time-of-year.

Humans uncontroversially project themselves, their “I” into the future and choose courses (in the present) to affect that future as such. If I am a competent architect with many successful projects, I do confidently project myself, that is the same self that today begins a new project into a future time when that project will stand completed. Of course I understand that contingencies beyond my control might block the future I envision. My present choices do not determine that future, but much experience supports our confidence that we can, under most circumstances, bring about that which we project and that the same “I” will own the completed project in the future as now takes ownership of its beginning.

Many people tell me that their person is not changeless. They look back and remember themselves as much younger people and declare that, of course they have changed since then! But when I point out that they also remember being the person who was once “that way”, the person who owned those differences at an earlier time they admit that this is so, but attribute this seeming merely to memory. This is not correct. They are confusing character with personality. Yes, their character has changed, and yes, they remember their old character. But they are also aware that a single entity has been present throughout those changes, an entity that owns and is responsible for them all. That thin sense of “awareness of sameness” is our only direct phenomenal handle on personality.

Memories are, as it were, complicit in our sense of changeless ownership because even that sense is had in and through consciousness. Personality is the core of our sense of changeless ownership, but it is that plus memories and synchronic (moment by moment) awareness that constitute the sense of identity as a gestalt. That memories are not the sole source of our identity is demonstrated by wide gaps (years perhaps) in memories of early childhood while we yet we retain the sense of ownership over those coming both before and after the gaps.

Even when my memories of some particular event completely disappear, for example as concerns my very young childhood of which few memories remain, there is nothing in my experience to suggest that I was literally a different person at that time. We have a very strong intuition that in that past we were still the same self as we are today even if everything about that self, memories, character, etc, have changed. But memories are important to our integrated mind/person sense of self. Without them, the personality has no purchase on what, exactly, it is a changeless core of…

— Free will

Free will is a power of mind. It is mind’s capacity to initiate causal chains in the universe that are both volitional and purposeful; causal chains that are not fully determined by prior physics. Higher animals have it. Human mind, has the capacity to discriminate values (truth, beauty, and goodness) and thus can exercise free will with respect to them. Animal mind is in someway affected by the values but they cannot choose with regard to that which they cannot as such discriminate.

Animal mind however is temporally constrained in two ways, human mind only in one. Humans and animals can exercise will only in the present. In addition, animals can only exercise will for the sake of the present. By contrast, humans can exercise will for the sake of the past and especially for the future. Like self-consciousness, this difference in human consciousness is a function of personality’s substantive reality, in this case, its changeless persistence. We have a binocular appreciation for the depth of time, the relation of past to present and future, because we have a reference, a thin awareness of changeless ownership of our experience beginning sometime in the past.

This awareness of ours has both a qualitative and quantitative character. As we “grow up” we are qualitatively aware of a significance to larger intervals of time. We are quantitatively aware of the magnitude of the interval through we ourselves have passed. We can be aware of these things because we have a changeless reference providing the temporal contrast to present experience.

The future has been open since the big bang but not until consciousness comes along is there something in the universe that can take advantage of its openness. Not until personalized consciousness comes along is there something in the universe that can freely elect purposes with which to direct action having only a contingent relation to the present in which the choice is made. We must begin somewhere to constrain the future and shape novel outcomes that are the end-products of those purposes plus our skills in acting over time to fulfill them.

This sort of freedom, not only the freedom to choose but the freedom to choose for the future cannot come from physics in which no mechanism, individually or in their totality, exhibits any present let alone future oriented purpose.  Because our (human) partial-temporal-liberation is a function of personality’s changelessness, it can have only one source, a “changeless God” who can ground (is the only possible ground) of changelessness. God is the direct cause of personality.

The metaphysical inference

Neither of the three contributions of personality to consciousness appear to exist in animal consciousness. If consciousness is an emergent combination of brain resonances and Cosmic Mind, personality is a further information imposition on that consciousness. From our viewpoint, it all just looks like consciousness. Only God knows what part of our phenomenally unified consciousness is “the person”. That explains personality’s “epistemological transparency”.

Constancy is nowhere to be found in the physical universe except in personality. That constancy is personality’s distinguishing passive characteristic. Changelessness in time, in turn, sets up our capacity to experience directly the relation between past, present, and future. Our fixed point of temporal reference in the past that permits projection into the future. Animals have only the present and memories. It isn’t clear that their memories engender any intellectual sense of an abstract past in animal experience, but clearly we have one.

Self-consciousness is a property of the relation between personality and consciousness. Personality provides the contrast, the transcendence, needed to reflexively examine our own consciousness. What we find in that examination is of course partly the person indistinguishably (from the subjective) fused with the consciousness being examined. But that we have this recursive ability at all can only be because something about the fused entity transcends consciousness simpliciter. Changes in the content of consciousness of all kinds can be viewed abstractly thanks (in part at least) to the contrast generated by personality’s constancy. Finally, a temporally liberated free will is personality’s distinguishing active power. Persons are free to become purposeful original-causal agents and elect to effect (attempt to effect) temporally distant purposes.

Personality therefore belongs in our ontology. It must be real even though we cannot identify it directly and it must come from God because he is the only possible source of changelessness in anything. It is transparent, in the final analysis, because nothing distinguishes it from the mind gestalt in subjective experience  (epistemic transparency). Personality permits mind to recursively examine itself, but there is nothing further to provide contrast to personality — and this puts paid to the homunculus problem. We experience personality only within the fused whole of our consciousness.

In a wider theological context there is more to be said about personality, but that “more” has nothing to do with our present [phenomenal] experience of it, but other inferences that can be made from its existence and origin. I discuss one of these in another essay. see “Why Free Will?”
