What are Qualia and Why are they Interesting?

In this short paper my purpose is to understand how the word ‘qualia’, plural of ‘quale’, is used and to what exactly it refers. In addition I address the question of the phenomenon’s importance.

Qualia are associated intimately with brain states, and never occur in their absence. It is a fair bet there is some corollary brain state (sets of brain states) associated with every quale and the collection of them. It is also the case that, while normally associated with sensory apparatus, it is possible to invoke qualia, even a specific quale like “a flash of red light”, by “poking the brain” direct. What is mysterious about this is that poking the brain (or stimulating a living organism’s more conventional sensory pathways) does something that poking anything other than brains never does. It invokes, a “subjective experience” qualitatively different from the physical qualities either of the brain or of the source of sensory stimulation.

The sound of a middle-C note from a piano is a quale as is the different sound (thanks to harmonic frequencies) of the same note played on a violin. Each is a particular quale. What seems interesting is producing that note from either instrument, the motion of air molecules set up by the vibrating strings, and everything that happens between the instrument and the middle ear is mechanical. Mechanical energy converts to electrochemical energy in the auditory nerve and spreads in that form through the entire brain. From instrument to brain everything is uncontroversially physical and well understood. But what emerges, what is invoked by all of that physical process, a content of subjective experience, is not uncontroversially physical. It has qualities that none of the physical forerunners have. What is it exactly, and how is this possible in a physical universe of causal closure where physical causes have only physical effects? Those questions make qualia interesting.

In a sense, and this is only metaphor, it is as though a threshold is crossed. On one side a certain combination of purely physical (mechanical [hearing], chemical [taste/smell], electrostatic [touch], or photonic [vision]) energy (yes even the physical poking of a brain) is translated or transformed into a subjective experience whose qualities or properties share nothing in common (other than correlation) with the physical properties of their source. The mystery has nothing to do with the transformation’s necessary dependency on a functioning brain. Rather it is that this sort of transformation happens at all; that physics becomes subjective.

Sound, light, feel, smell, taste are all mind-dependent descriptions of phenomena, that in the mind-independent world are nothing but energy of one kind or another. If I say “I see light” we have always to remember that in mind-independent terms, there isn’t any “light”, only “electromagnetic radiation”. The latter is real and exists in the universe whether there are organisms with apparatus sensitive to it or not. Electromagnetic radiation only “becomes light” to a subject. Information bearing patterns in brain states are translated (mapped), via pathways beginning with sensory apparatus, into an “interior experience”. “The light” is that mapping!

The subjective gestalt is composed of qualia similar to the way particles of the Standard Model comprise the mind-independent world. The particles collect in special ways to form atoms while the atoms (sometimes in special states) aggregate to produce everything else. Some of the phenomena of the mind-independent world impinge on certain “biological sensors” associated with brains. Not all mind-independent phenomena impinge to trigger biological sensors. Neutrinos do not, nor photons outside a limited range of wavelengths.

The subjective arena is broader than qualia alone. Intentions, beliefs, emotions, memories, ideas, and so on are not qualia. Qualia comprise only the sensory modalities of the gestalt (and sometimes the effect of brain pokes). Unlike atoms, there are genuine mereological sums of qualia that is itself a singular quale.

The qualia arising most directly from our physical senses, “atomic qualia” like a particular red experience, sum mereologically to a unified gestalt experience, the sensory ingredients of the subjective arena of which we are conscious at any given moment. Nor at any moment is the arena an equal mix of all sensory impingements of which we are aware. If I am driving I am aware of the feel of the wheel in my hands, the pressure of the gas pedal on my foot, the sounds around me and the aroma of the hot pizza on the seat next to me. But I am, for good reason, focused on the visual scene in front of me. My gestalt includes all the sensory modalities of which I am aware, but as I focus my attention on what I see, qualia arising from sight dominate my arena in that moment.

The relation between separate sensory impingements is constantly changing but the effect, subjectively moment to moment, remains always singular. All this singular arena, taken synchronically, is also properly called a quale. By contrast, the mind independent world is particularized. Yes there are aggregates there, but they too are particular instances of their types. Planets and chairs are aggregates of atoms, but they remain, mind-independently, particular planets and chairs. That they are particular totals is recognized in the subjective interior thanks to the distinguishable qualia they invoke (via brain states) and their summation to the interior gestalt. The mind-independent world is essentially particular, while the subjective arena, under normal circumstances, is intrinsically unified.

None of this usage hangs on any particular theory of or philosophy of mind though it does implicitly reject eliminative materialism. It requires only that the word qualia refers to something, not nothing. That something, that to which we give the label ‘qualia’, is both the individual and totalized sensory modalities of our moment by moment experience. If, apart from qualia and besides intentions, thoughts, and so on, there is a “subconscious mind” and perhaps even an “unconscious mind”, there are no subconscious, let alone unconscious, qualia. A sensory experience isn’t a quale unless one is aware of it!

Qualia are nothing like examples of “emergent phenomena” one meets in the science and philosophy literature, for example the relation between statistical mechanics and thermodynamics. Statistical mechanics is about the motion (and density) of atoms; uncontroversially physical. Thermodynamics, temperature and pressure language, frames “another way” to talk about the same phenomenon. Mathematically, one can demonstrably map one into the other.

Qualia certainly rest on the “motion of atoms” (a synecdoche for simplicity’s sake), not only those that stimulate the sense apparatus, but throughout the brain. There is surely a causal relation here. Yet it is not obvious that “qualia language” is merely another way to talk about brain states. Not only has no one connected them mathematically, no one has suggested what the equivalence conditions might look like. David Chalmers, for example, speaks of “bridge laws”, but in several books on the subject has not suggested just how such laws would be subject to equivalency demonstration on either side of “the gap”.

The brain is a species of portal (a metaphor) made of the same stuff as all the mind-independent world. Some of the phenomena of the mind independent world are able to impinge on the portal in such a way as to invoke, a subjective viewpoint, qualitatively different from the electromagnetic, mass-possessing, stuff underwriting it; something, the subjective experience, that isn’t composed of atoms at all! Consider that my experience of red exhibits no third-party measureable quantity despite being the product, a mapping, of electromagnetic energy!

Of course the brain state correlate grounding the quale exhibits energy, even producing heat. But there is no physically measureable quantity on the subjective side of the portal! Brains translate, map, or convert energy of the mind-independent world into subjective experience which, as such, exhibits no energy utilization over and above that energy accounted for in the activity of brains; activity of atoms that hasn’t the slightest resemblance to its mirror on the other side of the curtain.

So why, as philosophers, should we pay any attention to qualia, brain states being obviously necessary and possibly (less obviously) sufficient for their appearance? Supposing we eventually learn exactly which brain states evoke every specific quale of the subjective gestalt, wouldn’t that constitute “knowing enough”? The problem is two-fold. First qualia do not have any of the measurable properties of brain states. At the same time, they do have properties of their own sort. If I ask a philosopher or physicist “to what does the word ‘qualia’ refer?” few would say “nothing”. But if not nothing, then what? My subjective experience of a color, or of my moment by moment phenomenal arena is not “made of atoms” even if it is a specific material organization, living brains made of atoms, whose activity is responsible for them.

Second, doesn’t this phenomenon smack of mystery “begging for explanation”? Why is the quantum mechanical “measurement problem” interesting? Why do we try so hard to understand what is going on? Something is going on about or in the “quantum world” that becomes counter intuitive when it emerges into the macroscopic. We’d like to explain how this transition works and why it comes out in the particular way it does. But we cannot and the most pedestrian of the fundamental reasons for this is that our instruments cannot get there! We cannot probe the quantum world directly. Why is the proton/electron mass ratio interesting? Why does it beg for explanation? Because it is unique and uniform. Every proton throughout the universe weighs the same as every other proton and mutatis mutandis for the electrons. It is that singular uniformity that makes the phenomenon interesting.

Why are these phenomenon any more interesting than qualia? First there is only one material organization in the universe, brains, that mediate between the impinging mind-independent matter-energy universe and a subjective experience of qualia? Second, like the quantum world, our instruments cannot get there! Even if we knew in every instance what brain states evoke what qualia we would be no closer to answering the question: how does physics become subjective?

Chalmers has pointed out many times that this brain state business might go on, like any other complex matter-energy interaction, without evoking a subjective mirror of itself. Biologists surmise that having a consciousness, and therefore a control (presupposing free-will by the way) over behavior beyond what is possible for non-conscious (automatic and deterministic) neural activity has survival advantage. Ironically, biologists have answered a why question. Physics produces the subjective because it has survival advantage! Surely this is so. But it gets no closer to answering the question how physics evokes a subjective? What makes it possible for physics to have that effect?

Every other matter-energy transformation in the universe, every other emergent phenomenon both begin and end with matter-energy. This includes what goes on in brains! And yet at the same time, and only in brains, there comes to be a “subjective viewpoint”, a phenomenon that begins with matter-energy, but does not end with it. Is that not enough to make it interesting?

All Will is Free

The goal of this short essay is to argue the word ‘will’ and the phrase “free will” are equivalent. The ‘free’ in “free will” is redundant. All exercise of will is free. There is no “un-free will” although there are un-free actions that aren’t willed.

First let me set some boundaries. I am not trying to establish that free-will is real. This argument is about the ordinary language, conventionally subjective view of our agency. We seem to ourselves (and as self-as-such) to be final arbiters of some physical (bodily) behavior, even if the result is not exactly what was subjectively intended. If with my arm, hand, and fingers, I propel a basketball towards the hoop my goal, to make the ball go through the hoop, may not be what occurs. Nevertheless, it “seems to me” that I, the subjective agent, am the agent-cause of the throw. My agency caused my arm to move or at least this seems to be correct from most people’s viewpoint. My argument below does not hinge on whether libertarian free will is real, but only that it is possible.

We, as agents, seem to make choices. Our [seeming] choices often precede a controlled action (behavior) of our body, and it is those physical actions that are causes in the physical world. These acts are efforts to constrain future possibility to present fact. These causes are NOVEL in the sense that they have, at their beginning a selection by a subject and not merely firing a neuron. A “selection by a subject” is novel because it does not presuppose any prior physical determinant as would the mere firing of a neuron. We are not simply aware of a choice having-been-made. Subjectively it feels like we are the initiator of the choice. A choice resulting in an act of a body seems always entangled with a willing. I decide to order item #26 from the menu before me, and in making that choice I will my vocal apparatus to express it to the waiter. Some would say the vocalization is making the choice and this would be true from a third-party perspective. Subjectively however, we do usually seem to make a choice (decide) before willing an action.

This does not mean there were not physical causes (brain states) before and so impacting the choice or the willing. Nor does this mean there is anything about the experience of choosing and willing, without some brain-state correlate. What’s importantly characteristic of our experience here is that all the prior physical causes together are not sufficient, subjectively, to determine rigidly what is willed; the agent has the final vote, and this vote matters. At least this is what it feels like.

Not all actions of human or animal bodies are a result of willing. Heart beat and breathing come to mind, but there are less trivial examples, including many habitual behaviors and other actions that occur without our thinking about them. Such actions are not ‘novel’ in the sense that I mean that term. They are not sui generis because they are fully determined, that is sufficiently, by prior (neurological) physical causes. Importantly, we do not usually think of ourselves as willing such acts. We are surely not willing a muscle reflex and it does not often seem to us, when habitual behaviors are called to our attention, that we are willing them either.

In addition, even consciously willed acts, if they are free at all, are not free in any absolute sense. It is the body firstly that is the starting point of the physical causal chain initiated in the world. The act is always physical. Once a body acts (freely or otherwise), the causal chains started are beyond that body’s control. In addition acts themselves are constrained by the limits of what the body can do. Moreover, they are limited by what that body’s [seeming] subjective agency recognizes of its alternatives. We cannot do what the body cannot do (for example fly) and we cannot choose from among genuinely available alternatives (physically possible actions we might take) of which we are unaware.

Nicholas Rescher (“Free Will: A Philosophical Reappraisal” 2009) makes a distinction between moral and metaphysical freedom. Metaphysical freedom refers to all the future possibilities that might contingently happen. Philosophers and physicists are used to the idea that the present physical universe is contingent meaning that what has happened might have happened otherwise. Many events might have happened in the universe that did not happen, and more importantly, many future events are possible and we cannot be sure which of these will occur. Metaphysical freedom in this sense has nothing directly to do with willful agency. In Rescher’s view it is genuine and we have access to it, but we have access merely because it is a property of the physical world with which we engage.

By contrast moral freedom comes down to a conscious agent being free to choose from contingent futures without a constraint (agent or otherwise) fixing the agent’s act (and so will) in some specific way. If someone puts a gun to my head and tells me to open the safe I am not morally free in Rescher’s sense. But I am still metaphysically free. I could choose (and so act) to resist the gunman! I will get to the implications of Compatibilism for this argument shortly.

Animals appear to exercise will. Are they also free? I believe the answer is yes, though their freedom, their awareness of potential freedom is more constrained ours. Animals can do what they want in the absence of constraint. In this sense (absent constraint) they are morally free in Rescher’s technical sense. If metaphysical freedom is real, then animals must also be metaphysically free (ontologically speaking). A lioness on the hunt willfully selects between two possible zebras present to its awareness and so willfully acts to chase one of them. But the lioness cannot choose to forgo the hunt and become vegetarian even if there is plenty of nutritious vegetable matter in easy reach. Selecting one zebra and not the other is a freely-willed act, both morally and metaphysically, within the scope of lion consciousness.

Richard Swinburne (“Mind, Brain, and Free Will” 2013) argues that only a rare, deeply considered moral act, is genuinely free-willed. Everything else, despite how it might seem to us subjectively, is determined. Galen Strawson (“Free Will and Belief” 1986) argued that because so many of the past influences on our choices, beliefs, and so on, were not freely chosen, we are not free ever! Strawson’s argument is that unless every influence on a present decision was freely chosen, the present choice cannot be free at all! Strawson does nothing to address the phenomenological (the seeming) or linguistic issue here. He denies the possibility of metaphysical freedom by fiat. But both human language and experience easily distinguish between a seemingly free act and an act that does not seem to be free. Perhaps not always, but if we can make the distinction even sometimes, then metaphysical freedom might be real! If in a long chain of influences not freely chosen a single choice, however narrow, is freely elected then free will is possible.

Assuming Strawson (or Swinburne) is correct in what sense are all of these determined choices “willings” other than merely being a “figure of speech” that has no referrent? If our brain alone fixes what we do in what way are we, our subjective self, willing that act at all? To be sure what seems like the result of a willing might be an illusion. But in that case, not only are we not free, we are not really willing anything either.

This brings me to Compatibilism. If someone puts a gun to my head and orders me to open the safe I am acting unfreely by compatibilist lights, and yet I am obviously willing in the conventional linguistic sense. I must exercise will to move my arm and hand to the safe and dial the combination. According to compatibilists my will is not exercised freely. Here Rescher’s distinction between moral and metaphysical freedom is helpful. The gun to my head makes me morally unfree. Few would suggest that I have a moral duty to resist the gunman. Yet according to Rescher, I remain metaphysically free. I could resist the gunman, or try to escape. These are genuine options in that they are possible courses of action, future potentials not precluded by physics from which I might select. My willing my hand to dial the combination is still an exercise of metaphysical freedom.

‘Will’ and ‘free will’ do come apart in Compatibilism because compatibilists deny that Rescher’s “metaphysical freedom” exists at all. That is precisely the compatibilist’s point. By compatibilist lights, metaphysical freedom in Rescher’s sense is mere illusion. To all intents and purposes, at least as concerns macro-physics, events of universe history are not contingent but fully determined.

If compatibilists are right however, it makes little sense to speak of any willing going on either way. If there is a gun to my head, my brain, and not any willing makes me, my body, open the safe. If there is no gunman, my brain might determine that I finish up some work before going home. Either way, what seems to me to be a free-choice willing (I could leave the paperwork until the morning) is not real but merely a seeming. For compatibilists, there is no will at all, only the illusion of one. Put otherwise, there is no such phenomenon as “unfree will” because there is no real will at all!

If compatibilists are wrong and Rescher is right (it is metaphysically possible to resist the gunman) then any “act of will” is an act of “metaphysically free will” notwithstanding there are many past influences, not freely chosen, impinging it, or even that the choice was not morally free. If agents are metaphysically free, if subjective agents can choose between genuinely alternate futures then the subject, and not merely the brain, becomes a part of the causal chain resulting in a particular future out of many possible. If ‘will’ represents anything more than a figure of speech, metaphysical freedom has to be real.

Compatibilists speak of will as though it was real but by their own lights it cannot be. We seem to perform choice-act combinations by willing. If we don’t “will it” (and I grant that not all acts are willed or free) then nothing happens; no act will issue from a body. Importantly it also seems that no act of a body that is not willed is free; we are not free to suppress a reflex and we easily distinguish between willed and not-willed action under normal circumstances. If every free act is willed, and will is not an illusion, and no un-willed act is free, then no “act of will” can be entirely un-free (fully determined) and the ‘free’ in “free will” is redundant.

Book Review: Self Knowledge for Humans by Quassim Cassam

selfie

A philosopher needs both breath and depth in the discipline. There are a certain range of issues in which I have a primary interest reflected in all of the essays on this blog. But a philosopher cannot rely only on the writings of others in their field. To understand the implications of even narrow issues, one must read both opposing voices and something of other issues that may be but peripherally related. For me this is one of those books.

Is self-knowledge of the substantial variety on which Cassam focuses important to me as a person? Yes to some extent it is, and in fact the author covers that “to some extent” very well in his last chapter. Is self-knowledge important to me as a philosopher? Is it important to my specific interests? In my case crucially yes, but it is not a sort of self-knowledge, a knowledge of beliefs and why I have them (I do know what I believe and why I believe), wants, emotions, and character traits addressed in this book.

What I need better to understand is the quality of my evidence and whether it is evidence for what I believe. My primary interests often impinge on philosophy of mind (not our belief that other people or animals have minds, but rather what mind is, what makes mind happen in brains, and how this relates to physics, biology, etc) and much of what I believe is derived from a phenomenal examination of my own mind. I want to know if what I discover in that examination is genuinely evidence for what I believe.

This is a question that Dr. Cassam misses. I make no criticism of his work here. It is clear from his exposition that the metaphysics of mind is not his subject. Who or what is this entity that believes, wants, feels, and has character traits? None of what Cassam writes here hinges on any particular metaphysical view of this entity. Yet surely an answer to this question is about one’s self? It is about what one believes constitutes the self. My interest is in what I might learn of the self as compared to knowledge about myself. While not addressing that question, this book provides a helpful context. Thanks to  my reading, I am better positioned to describe that entity and what I can (perhaps) infer of it in the context of self-knowledge more broadly conceived.

Self-Knowledge for Humans by Quassim Cassam (2014)

As with many other philosophy texts I’ve reviewed over the years this one is both professional and well written. There is almost a formula for doing good philosophy in the analytic tradition. Begin by clearly stating the nature of the problem you are going to address. Briefly review the history of the issue; make distinctions, show that the problem is more than trivial. Here the subject is something of a narrow subset of philosophy of mind, epistemology, phenomenology, and even psychology. It is the nature of what, how, and why we know, or fail to know, about ourselves as this pertains to our beliefs, emotions, desires, characters and more. Cassam sketches distinctions between the trivial and the substantial in self knowledge, and also the occasional (what I’m thinking, believing, feeling, wanting, right now) versus the standing (what do I believe, fear, want, and so on over time).

Next address the various theories about the subject in the literature and show why they are inadequate, if not entirely then at least partly. This review often, and in this case does, take up much of the book. Third make a positive argument for your own theory, in this case what Cassam calls “inferentialism”; describe it carefully and show how it addresses the inadequacies of the other dominant theories in the subject area. Then address specific objections to your theory advanced by others and show why they do not have the force their authors believe they do.

Cassam does all of this masterfully and manages not to be dry in the doing of it. He ends with two chapters on related matters, one being self-ignorance itself distinguished into variations and brought under his theory, and lastly a chapter on a meta-issue, why these inferences, why self-knowledge is or might be important.

Is Inferentialism convincing? Well yes, given how much Cassam emphasizes its broad but not always universal applicability. His claim is that Inferentialism covers much of the ground because it can be conscious or unconscious (sometimes this last is better understood as “interpretation”) and would often, but not always, be the dominant means by which we come to know things about ourselves. In short there are a lot of distinctions to be made about what self-knowledge is, and Inferrentialism happens to address all of them (including self-ignorance) to a greater or lesser extent, but is never, or almost never, absent entirely from the process of coming to know things about ourselves. Objections to the idea are unable to gain purchase because Cassam fully accepts that other theories have explanatory power here and there about this or that sort of self-knowledge, but points out that none of these, even if they happen to be operational in specific cases, preclude an inferential component to the path to self-knowledge. It is about as neat and tidy a package as I have seen.

“Self-Knowledge for Humans” would make a superb introduction to the style of Western Analytic Philosophy. In addition it well illuminates the issue and makes a substantial contribution to our grasp of what a solution looks like.

Book Review: I am a Strange Loop by D. Hofstadter

This book deserves a lot of additional commentary, but I will keep it short and begin with philosophy of mind’s “elephant in the room”; free will.

Hofstadter rejects free will. No such thing, any appearance to the contrary an illusion. But even worse, it is an illusion on top of an illusion (the agent whose will it is) on top of another illusion, mind, that is subjective consciousness, also illusion or at best epiphenomenal with zero power of downward causation. Of course. What else can he say? He is committed to all of this being nothing more than manifestations of physical process in the brain whose complexity in some unspecified way becomes self-referencing, creating some sort of physical effect (like a harmonic oscillation though he doesn’t say this) that magically transforms itself into our subjectivity. A harmonic oscillation (a complex pendulum) that becomes an unmeasurable (by third parties) interiority.

Despite this multi-layered trickery, Hofstadter uses the word ‘soul’ many dozens of times throughout the book, even calling human beings “spiritual animals” in his conclusion. To what, in this epiphenomenal context, can these concepts possibly refer? Nothing. They are meaningless terms standing for illusory abstractions. Surely he knows that these words, in a non-physicalist context, stand for something purportedly both real (not illusory) and yet non-physical. To be sure, even in their normal context they are vague terms and there is no end of debate among philosophers of religion about what they reference. But all agree they reference something not material. But God is a fantasy to Hofstadter. Words normally associated with “God talk” can be appropriated and made to mean anything one wants. Nothing about ‘soul’ or ‘spirit’ can be real. Although the words are real enough in the English language, they literally can mean nothing what-so-ever as  that to which Hofstadter applies them is ultimately an illusion.

Take beauty, the simplest of the values (truth, beauty, goodness) to grasp because we detect its manifestation in the physical world. Physical things (whether natural or artifactual phenomena, sunsets or art) strike us as beautiful or not but either way the perception of beauty is something that exists only in mind. We seem to see it in the material world, but there is not much controversey about its status as a purely mental phenomenon, coming out, in what would have to be Hofstadter’s view if he is being consistent, as an illusion in an epiphenomena. While having no causal power, our epiphenomenal mind can itself have an illusion about which we might report: “that is a beautiful sunset”. But this is but another behavior determined by the purely physical operation of our brains, a report that happens, magically to coincide with the illusion arising in a causally impotent epiphenomena having no correspondence what-so-ever to any physical quality of the sunset.

This leaves all of what Hofstadter says he values, the memories of a wife he loved deeply, and the children he continues to adore, his close friends, his career, all illusion. Memories are an imperfect mental record of past experience, but experience is nothing but effervescent epiphenomena. They don’t mean anything because meaning is intelligible only to a subject, itself an illusion. He likes to think he acts out of love for his children, but this is impossible unless there is downward causation. Love has an experience that is overtly more than its physiological concomitants. This part of it is quintessentially mental, and therefore epiphenomenal. There is nothing there that has any stake (and in any case cannot be a cause) in the behavioral game.  Like beauty, physics does not find love in the causal mechanisms of the physical world.

If Hofstadter is right, then we might as well be zombies of the sort envisioned by his student (years ago) David Chalmers. Our interiority would seem to belie that. Chalmer’s “philosophical zombies” (P-zombies) have no interiority, but then our having one makes not the slightest difference to anything we might say or do, like “I love my children”. There is no “him” (all illusion) there to love anything, only his brain that determines the verbal report made.

Hofstadter declares to us that he “takes mind seriously”. Another zombie-report forced on him by his brain, just as that same brain forced him to pen that book. This is not “taking mind seriously”. If you take mind seriously, then you have to come out a bit like John Searle (whose critique of “machine consciousness” Hofstadter swipes at here and there throughout the book). Searle takes mind seriously. He says that he cannot shake the feeling that nothing about the entire history of human experience, not to mention the day-to-day experience of individual humans, makes any sense, becomes unintelligible, unless free will, and even personal agency (for Searle at least of a functional and not ontologically real sort) are both real. Searle, being ultimately a physicalist, admits he cannot figure out how this would be possible, but he nevertheless cannot shake the conviction that it is. Hofstadter (Searle and many others also) has another option, one that his  sort of “taking it seriously” prevents him from considering. He could take consciousness, agency, and free will to be real, and conclude that therefore physicalism must be false!

If one takes mind, and provisionally like Searle, free will and agency seriously, if physicalism is false, then one moves on to asking what must be the case about reality as a totality that makes these phenomena possible? What must be true about the universe if these subjective experiences are experiences of real phenomena? This is a question that Hofstadter, like Searle, cannot bring himself to ask.

I Am a Strange Loop by Douglas Hofstadter 2004

Douglas Hofstadter, justifiably famous for “Godel, Escher, Bach” wrote about the much trickier subject of mind and personal identity in this 2004 book. It is one thing to analyze the relation between three applications (their results in Math, visual art, and music) of self-referencing thought, and quite another to analyze the entity doing the thinking. Hofstadter begins with Godel because as it will turn out, his insight into the recursive descriptiveness of number theory from which self-reference was (supposedly) banned by Bertran Russel, becomes his inroad into a philosophy of mind. Hofstadter is a master at describing (without mathematical formalism) what Godel did and why it matters. He is not so good at applying this to mind.

Besides Godel, the author’s other insight comes from the loopy-like nature of recursive entities like infinite halls of mirrors or what happens when you point a television camera at the screen displaying what that camera is viewing. We all have seen these, and from these two things, Hofstadter assembles a theory of mind based on the idea that whatever goes on in the brain at the low and mid physical levels results in some sort of abstractions (perhaps manifested in harmonic oscillations of electromagnetic energy) that from another perspective, are the very stuff of consciousness.

There is nothing particularly new about this. Rejecting religion or other basis for any sort of dualism (and his remarks are rather disparaging in this respect) and declaring oneself a physicalist (there is nothing more than physics) is par for the course and occasionally swatting straw-man arguments to the contrary, is all part of the contemporary game for most of today’s philosophers and scientists. Besides religion he mentions David Chalmers who was, apparently, a student of Hofstadter’s in his doctoral days and rejects Chalmer’s non-religious panpsychism (and along with this presumably Davidson’s “dual aspect” monism as well) which is fine as far as it goes.

Hofstadter’s theory is somatic. Mind arises from what goes on physically in the brain and nothing more. The problem is he never gets to connect up the subjective with anything that can, even in theory, be measured by third parties. This is not to criticize him alone here, no other physicalists (or for that matter panpsychists) manage to do it either, but in this case the author jumps from the neurological layer to the concept of self-referencing abstraction (presupposing consciousness) without pointing to anything in between that might connect the two.

After declaring his theory “explained”, Hofstadter moves on to considerations of how one strange loop-abstraction, the one that fools me into the illusion of a stable “I”, is influenced and modified by others. He is much impressed by Derek Parfit’s thought experiments [supposedly] demonstrating that what we take to be the uncopyable core of ourselves, is nothing but effervescent illusion and can in fact be copied. Moreover, though we cannot copy it today (and may never be able to do that in reality) we can, from our own interiority, find ourselves being partial expressions of other people, their strange loops!

He supposes that our own personal-identities form slowly as we proceed from infant to child based on all the various influences that impinge on us from the world as these come to influence new effects in our own minds. The totality of all this over time results in a relatively stable, but not changeless, personal identity. He moves on from there to suppose that those we hold and know particularly closely (our parents, wives, children, siblings, etc) can cause their own identities to be partly duplicated in our own minds. None of this really makes sense. Of course someone with whom we are close for many years will have a proportionally larger influence over the shape of our phenomenal arena. What he doesn’t seem to appreciate is that this influence takes the same pathways (our interpretation of sensory experience for example) as the initial early development of our own personality. There isn’t any loop in my brain that is a copy (however imperfect) of my wife or children’s identity, only modifications of my own that represent them.

There is much here and I do not doubt that writing “I am a Strange Loop” was a labor of love in more ways than one. It is, as with other somatic theories, even possible that oscillating fields in the brain have a lot to do with consciousness and personal identity. There are still reasons to believe that this is not the whole story.

Answering 5 Questions: the Relation Between Science and Religion

The work of another, even a work unread, can suggest new blog material. On Twitter, one philosopher I know called attention to another, Dr. Gregg Caruso, whose primary interest appears to be arguing against the reality of libertarian (or contra-causal) will.

I have not read Dr. Caruso’s books, but titles like: “Free Will and Consciousness: A Determinist Account of the Illusion of Free Will” (2012) or “Exploring the Illusion of Free Will and Moral Responsibility” (2015) imply a position contra-free will. I have written about what I take to be the self-defeating absurdity of the position in  essays on this blog and in my books (see “Arguing with Automatons” and “The Nonsensical Notion of Compatibilism”).

Dr. Caruso has also written “Science & Religion: 5 Questions” (2014) in which he asks questions of some 50 scientists and religionists. I have not read this book either, but its description on Amazon does list what I take to be the thrust of the questions, providing me with an opportunity to explain my own views on this subject.

1. “Are Science and Religion compatible for understanding cosmology, biology (including the origin of life), ethics, and mind (brains, souls, and free will)?” And “do Science and religion occupy non overlapping magisteria?” I lump these two together as they appear to be different approaches to the same question.

2. Is Intelligent Design a scientific theory?

3. How do various faiths view the relation between science and religion?

4. What are the limits of scientific explanation?

5. What are the most important open questions, problems, challenges, confronting the relation between science and religion?

The questions as phrased are over-broad. Look at question #1 which includes everything from cosmology to mind-entangled disciplines like ethics and references to souls. Questions like this seem set up to make one side or the other look foolish. The literature is rife with confusion on this subject (see “What is ‘The Soul'”). Nor do any of the questions hint at any distinction between religion as it pertains to the individual and religious institutions. The dictionary is not helpful here. In modern terms, an individual’s religion is nothing more than an institution into which they are born or join later in life. The word ‘faiths’ in question #3 seems clearly to mean institutions, but questions #1 and #5 are ambiguous on this distinction.

There is definition of religion going back to the Greeks. Your religion is your relationship to God however you conceive it. This definition implies a distinction between “religion as such” and “religious institutions” (if any) to which you happen to belong. If there happens to be a personal (Abrahamic style) God, then we, being persons, each have some individual relationship to him whether we recognize it or not. This relationship is personal and except for ethics (via morality) has little direct connection to any of Dr. Caruso’s questions. Of course an individual’s intellectual interpretation of that relationship (even that it doesn’t exist) is another matter.

By contrast, religious institutions are social (interpersonal) and physical things like banks, schools, and offices. They have documents, buildings (see Searle below and Maurizio Ferraris), leaders, and members (customers). Religious institutions differ from the others only in that they purport to be about God. (there are exceptions. Buddhism in its original form denies the reality of anything like a God with whom one can have a relationship and yet remains a “religious institution”).

There is only an accidental relation between the teachings of the institution and the individual’s relationship to God. By-in-large, the individual accepts for her own belief system the teachings of the institution. Such intellectual acquiescence impacts the comprehension of the individual’s relationship to God, what they take to be their “personal religion”. But it does not actually alter the relationship as it is (or would be) from God’s viewpoint.

These two meanings (institution versus relationship) of ‘religion’ are literal. A further, metaphorical meaning, might or might not refer to God, but to whatever one takes to be a “founding world view”. This metaphor is captured in utterances like “science is my religion” meaning that science (what the individual takes it to be) is the foundation, the set of propositions on which every other belief (consistently or not) rests. There are many of these metaphorical religions. Almost anything over which human beings can obsess can become one. I will not be concerned with these metaphors here, but I note that if the individual’s intellectual foundation is a God-concept then the metaphor becomes a literal personal religion.

Besides being ambiguous about religion, question #1 is vague about science. Are we speaking of physics, chemistry, and biology, or psychology and “social science”? Are these all ‘sciences’ in the same sense of that term? I suspect not. In fact, what separates the hard from the soft sciences is the latter are in one manner or other entangled with the doings of minded beings while the former are not. The hard sciences are strictly about the material world and discoveries are (or would be) valid even should no minds exist in the universe. But if mind did not exist, there would be no psychology nor any other of the “social sciences”. It is this intrinsic mind-entanglement that makes them problematic, quasi-sciences.

If God is real, then the personal relationship is real even if one denies it. One can say “I have no father” suggesting various possible metaphorical meanings, but they remain only metaphors. If you are a living vertebrate, you must literally have a biological father. The failure to make this distinction between different meanings of ‘religion’ muddies questions 1 and 4 which are otherwise different ways of asking more or less the same question. I will keep this distinction in mind throughout the essay.

Question #1. To the first part, The short answer is NO, To the second, YES. Science (hard science) is about the material world. Religion is about the relation between human beings as subjective entities and God. Religion (personal or institutional) has no business saying anything about physical mechanisms other than that God is ultimately their source.

The greatest and most important insight of hard science is that physical mechanisms are free of teleological encumbrance; they are purposeless! This does not mean the existence of the physical as such is purposeless. God (if he exists) might have a purpose for a physical universe of purposeless mechanism (see “Why Free Will”). Religion has no business making pronouncements about any detail of physical mechanism, while science has no business declaring God’s non-existence based solely on its evaluation of physical mechanism whose [possible] overall purpose science is not qualified to evaluate.

Mind, whatever it is, complicates this picture because science is done in mind by minded entities. Clearly mind of the individual variety with which we are familiar is a part of the universe. There are minds in the physical universe. But whether mind itself is physical, or takes origin solely from the physical is problematic. The methods of science so well adapted to explicating purposeless mechanism are ill suited to evaluating purposeful mind. Purpose enters the universe through mind.

If God is real, then substance dualism is possible and not problematic except for the infamous “interaction problem” (see “Fantasy Physics and the Genesis of Mind”) which science is not qualified to resolve other than to say the interaction must take place in brains whose material mechanisms are within its scope. Nor is there any reason to believe that religion (or philosophy) is qualified to explicate the interaction. My relationship to God does not require that I understand how mind is evoked from (or evokes) events in my brain. There are several related interaction problems. I will not concerned myself with their details here (see essay linked just above).

The first question throws together so much it is impossible to answer it straightforwardly. For example libertarian free will (or the illusion of it) is something that only appears, like purpose, in association with minds. Science (meaning the “hard sciences”) by itself suggests that such a thing is impossible, but then again as John Searle says (“MIND” 2005, “Making the Social World” 2011, and “The Construction of Social Reality” 1997) nothing about human experience makes sense unless libertarian free will is genuine (Searle being an atheist admits that he cannot resolve this riddle). Indeed, accepting that a contra-causal (meaning that, as Sean Carroll puts it, “mind causes physics”, something Carroll denies — see  “The Big Picture” 2017) free will must be genuine is among the strong philosophical reasons to believe there must be [something like] God.

Ethics (also lumped into question #1) only makes sense in a free will context and resides in mind where decisions of moral import originate. Ethics is a social reflection of morality. It entangles the physical world only after some free willed choice made in mind. There is nothing for science to do here other than to illuminate the limits of what is possible given the bodies our minds control are physical. This includes, for example, the discovery that certain disease states of the brain might make ethical evaluation impossible by the consciousness evoked in such brains.

The contemporary notion that we can derive an ethics scientifically is ridiculous. Ethics, being about the interactions of the bodies of minded persons can be described by [soft] science and [soft] science can help to determine the reason-ability of various ethical ideas,  but ethics cannot be logically derived from science in any normative sense.

Question #2. Intelligent design is a hypothesis but not scientific because it implies purpose-directed (i.e. not purposeless) mechanism underlying certain observed physical phenomena. That doesn’t mean it has nothing to contribute to the debate. Intelligent Design is not Creationism!

Dr. Caruso’s book includes William Dembski (“No Free Lunch” 2001 and “The Design Inference” 2006) as a contributor. Dembski concedes his belief in an Abrahamic God, but his work does not commit him to this detail. Dembski’s point is that an accidental origin of life and its evolution (on Earth) to its present state is highly unlikely.  Dembski’s hypothesis is a statistical argument from empirical data — life’s extraordinary information content! It looks to Dembski like intelligence is involved in the process, but he is strictly committed only to the unlikeliness of its being an accident.

Dembski can easily get what he wants in a Darwinian context. His work only requires that not all genetic mutations are random! If I drop 1000 coins onto a floor and then deliberately flip 10 of them, will any statistician (looking only at the result) dare to say that the distribution of heads and tails is not random? If over 3 or 4 billion years 99% of mutations were random, but 1% were not, how would we from our present perspective ever tell the difference?

The origin of life (like the origin of the big bang and the value of the cosmological settings) is a special case. Physics entails that a contingent origin of life must be possible. Dembski concedes this. His claim is that such a beginning is unlikely and he makes a well argued case for that view. He does not insist that therefore an Abrahamic God must be responsible for it. Dembski exposes the unreasonableness of the near universal belief of science that life originated and evolved to its present state entirely by accident. That no one has come up with an alternative between accident and intelligent design is not really Dembski’s problem.

Question #3. The problem here (“faiths” referring to “religious institutions”) is that all the [major] faiths are based on “holy books”, the writings of their founders usually (but not always) taken to be divinely authored in some direct or indirect manner. The people (and leaders) of these faiths have, by in large, absorbed the idea that their textual sources are infallible. Not every religious institution on Earth believes this basic falsehood but to one extent or another, they hold the value of all parts of these texts to be roughly equal.

In these texts, statements consistent with a first principles theology (see “Prolegomena to a Future Theology”) are admixed with others that plainly contradict them. Moreover, these books (in particular the Bible) purport to tell not only the history of the faith, but of the world beginning with its origin and all of history between then and their writing. Some of this exposition concerns mechanisms of the physical world. They are all pre-scientific and should not today be taken seriously, other than as [possibly] great literature! I return to this in my answer to question #5.

Question #4. This question is implicitly answered above in my reply to question #1. To be brief, the scope of the sciences is the purposeless mechanism of subsystems of the physical world. Strictly speaking scientific method (methodological naturalism) cannot be applied (experimentally) to the universe as a whole. It cannot be applied, for example, to discover if the physical cosmos has a purpose in the mind of some god.

Because the mechanisms (events) of subsets of the physical are purposeless they behave always in the same way under the same relevant conditions. It is this consistency that enables mind (in which and by which the scientific method is deployed) to explicate the mechanisms themselves through observation and, where possible, experimental tuning of conditions. None of this has to do with the question of whether a god has brought all of this cosmos about or how that god might relate to minded observers arising within its physical context.

Once science turns its method on mind itself ambiguities necessarily appear. Mind isn’t [apparently] material for one, but it is unambiguously purposeful. There is nothing preventing a purposeful mind from starting different causal chains under identical material conditions. Science can address the material roots of mind, but applying itself to mind as such can never complete its explanations. This doesn’t mean it cannot help to narrow mysteries about the nature of mind’s relation to brains, but it cannot remove them as it can with regard to the behavior of the macroscopic physical world.

Question #5. This question is the most equivocal between the two literal definitions of ‘religion’, personal versus institutional. Conflict between “the faiths” and science will not end until the institutions (and by extension their leaders and members) give up the false claim that their texts are the work of God (see “Misquoting Jesus” Bart Ehrman 2009). There is a ready substitute (at least philosophically) in a “first principles theology” (see Prolegomena linked above).

Once institutions identify in their texts that which is consistent with first principles (legitimately discovered by human beings; there are a few qualities we can infer about God) the rest is free to be interpreted as literature. Literature has value, culturally and otherwise, but as science, as a description of the mechanisms of the physical world, it is only speculative fiction. Indeed, and for the same reason, “the faiths” have as much conflict with one another as they do with science. Different holy books contradict one another as much as they contradict themselves. The real God, like the real physical universe, must be free of intrinsic contradictions!

Science has, in the end, the easier job here. It must merely give up the claim to any authority on the question of God’s reality leaving all the rest of science unchanged. Because they are automatic, the purposeless mechanisms of the physical world can be explicated without reference to God (see “The Blind Watchmaker” Richard Dawkins 2006). But this truth has nothing whatever to do with the question of whether the cosmos as a whole is the product of a design having a purpose for purposeless mechanism observable and manipulable by purposeful mind!

Mind itself, its subjective qualities, is the evidence, albeit not scientific evidence, there is something more to reality than science can legitimately address. Because this evidence, experience itself, is not scientific the individual scientist is free (though ironically we might ask how so?) to reject, intellectually, the conclusion that there must therefore be something more than physics. But such a rejection is philosophical and not scientific. Speaking as a scientist, one should stop asserting there is not or (in some claims) cannot be, anything more than physics.

There is no question #6 but one comes neatly to mind. “What, if anything, can religion say about the purposeless mechanisms of the physical universe”? In “The Goldilocks Enigma” (2008) Paul Davies, speaking of “fine-tuning” from the cosmological settings to the geophysical evolution of the Earth, notes that “if God is real, none of this would be surprising”. This is what religion in its institutional form can say about physical mechanisms. Their existence as such is not mysterious; there is an over-all purpose to their being just the way they are, a  purpose to physical purposelessness!

What purpose, or what range of purposes? Religion can address these questions (see “Why Free Will” linked above), but doing so takes us immediately away from physical mechanism into mind and mind’s sensitivity to values, our only (and strictly mental; subjective) contact with spirit; the character of God. It should not be surprising that we must account for purposeless mechanism, purposeful mind, and mind’s sensitivity to values, in any inference towards an answer to such questions.

Institutional religion however does disservice to its flock if it claims absolute authority to specify every detail of what it can reasonably infer of God’s purposes. This is the same disservice done by scientists who claim that science as such rejects God’s reality. Religion must face its own limitations. It is it not qualified to make pronouncements regarding physical mechanisms, and it can never declare its interpretations, inferences, and conclusions about the relation between persons and God final! Philosophically it faces the same insurmountable “interaction problem” as does physics, though unlike some physicists (see “The Beginning of Infinity” David Deutsch 2012), it does not assert that mind must in the end be able to resolve every such question.

I would like to add one note tying this subject to what I take to be Dr. Caruso’s view that contra-causal and libertarian (not the same concept but always found together) will is physically impossible. None of the answers given above make sense if a robust libertarian freedom, at least for human mind, is not presupposed. Yes philosophers have constructed a conundrum called “theological fatalism” in which libertarian freedom is rendered impossible by the very infinity (omniscience) of God claimed by religionists (see “The Mistake in Theological Fatalism”). Here I note only that the matter is resolved by observing that human freedom is limited both as to conceiving and to acting in time while God’s foreknowledge is not. The outcome of this from our perspectival viewpoint is that God’s knowledge is not a cause of our choice. God’s knowledge also includes all possibilities from which our choice might be made. It is because we have real freedom from our perspective within mind that any choice, and in particular moral choice (the only domain in which our freedom is absolute) has any real meaning.

So following Searle, I have to say that nothing about the human experience, including all of its social history (including religion in both senses distinguished here), makes sense unless the robust reality of a libertarian free will is presupposed! I differ from Searle however. I do not automatically also suppose that this cannot be right because of the philosophical claim that this is impossible as no evidence of contra-causal cause has ever been found by physics.

It is my contention that the manifest freedom I exercise in dozens of choices made every day (most trivial, some of import) is that evidence! I concede that this is not scientific. This evidence, should it be evidence, exists in, and is only available to, subjective mind. Freedom is the quintessential manifestation of my agency, the central quality of my experience (noted ironically by Schopenhauer “The World as Will and Representation” 1844). There is in effect only one example of it in the universe, the connection between subjective consciousness and brains. But while brains can be studied by science, the experience they effect cannot except by report which is physical and can not evoke experience as such!

If then I take my experience of free will to be real then its [seeming] physical impossibility must mean that there is something else going on in the universe, something that must in some sense be independent of physics! If such considerations ultimately point to the conclusion that something like God must exist, then so be it. My aim is philosophical rigor based on experience, not rejection of possibility based on illegitimate philosophical induction on the part of physicists.

Fantasy Physics and the Genesis of Mind

selfie

Physics rests on the “causal closure principle” (CCP). The CCP has three legs:

CCP(1): Physics comes only from physics.
CCP(2): Physics produces only physics.

Together these say the physical effects we observe come only from prior physics, and physical causes (using cause in its common language sense) produce only physical effects.

CCP(3): There is no teleology in physical mechanism, no goal-directedness. CCP(3) is something of a corrollary of the first two legs. Physical relations and interactions are either determinate or indeterminate, but either way they are not “before the fact” directed at particular outcomes.

If God does not exist, the only philosophy of mind (PoM) consistent with all three legs of the CCP is eliminative materialism. Every other nontheistic PoM that rejects eliminative materialism and accepts that mind cannot be logically reduced to physics, violates the CCP in one or more ways.

PoM theories that claim mind exists in some sense of that word, that mind is real and emerges from ordinary physics without anything “in principle undetectable” (QM aside) added to physics to make it happen violate CCP(2) but not CCP(3).  They assert, plainly enough, that physics results in something that is in some sense non-physical, but mind’s emergence is just as accidental (contingent) as all other [physical] emergent phenomena (from stars to liquid water to life).

PoMs claiming that physics is incomplete, that something else must be added to ordinary (measurable) physics to make mind emerge (dual-aspect monism and panpsychism of various sorts) violate both CCP(2) and CCP(3).

Only theism can both accept all the CCP while accommodating mind’s reality (and for that matter libertarian free will). Theism also grounds our conviction of agency which nontheistic theories universally deride. I write about theism extensively but my purpose in this essay is to show that the [supposed] problems with theism for physics and PoM are no worse than those of nontheistic PoMs. This is to say both suffer from equally serious metaphysical and epistemological problems.

Being inaccessible to empirical (or for that matter logical) demonstration (or falsification), a “God hypothesis” is a speculative solution, a curve drawn arbitrarily to fit points (mechanistic nature of the universe joined with free will for example). Other speculative solutions, so it is claimed, are equally possible and equally impossible to confirm or deny. In fact however it is more difficult than it seems to come up with these alternative solutions. Speculative solutions that fit all the points (the mind-independent world and everything in experience) and remain logically coherent are difficult to invent. Many have tried. Like theism, atheistic attempts at solving the mind problem are also data-free speculative solutions because the data, mind emerging from brains, cannot be observed!

Physicists are often eliminative materialists (nothing emerges strictly speaking) or reductive-materialists (only an epiphenomenon emerges).  Only eliminative materialism is fully compliant with the CCP and logically coherent, but it is also the solution that is most prima fascia absurd from the subjective viewpoint it denies exists! Reductive-materialism either violates CCP(2) if epiphenomenal-mind is taken to be something real or it is logically incoherent! Physics causes the external conditions of a mirage, but the illusion that is the mirage happens only in a mind. An illusion presumes a subjective experience in which the illusion occurs.

The view that a non-material mind emerges from ordinary physics violates CCP(2)! The idea is coherent because mind is not taken to be an illusion. The problem is that no physicist has ever seen a physical phenomenon emerging into (or as) a nonphysical one. We see physics emerging from physics all over the universe from galaxies and stars to liquid water to life, but all of what comes of these events (causes and effects) is physical! The retort from physics is that we do not see any other non-physical emergence because the one such thing that has happened in the universe is the very mind we are trying to explain. Mind is the evidence that physics can produce mind. Surely this argument is circular? It plainly begs the question to say that the evidence physics alone can explain the appearance of mind is mind!

There are a few philosophers who follow the physicists here (John Searle, Bob Dole among others), but many philosophers see problems in this approach. First there is the circularity already mentioned, but in addition, this solution (whether it includes a role for quantum mechanics commonly cited by both physicists and philosophers) entails that mind’s appearance is contingent. Not only might it not have appeared in the universe, something every materialist accepts, but its appearance is mysterious. The mystery applies to mind in general, and individual minds in particular. Why is consciousness ubiquitous in animals with complex nervous systems?

Troubled by these problems, materialist philosophers seek solutions that remain [purportedly] physical while, at the same time, channeling universe evolution towards consciousness and by doing so taking its mystery away. But every one of these solutions violates CCP(2) and CCP(3)! The idea that universe evolution is directed is plainly teleological! This is what prompts philosophers (and some physicists) to grasp the straw of quantum mechanics,  but this (I will argue) doesn’t help them.

To explain genuine mind in a Godless universe there are dual-aspect monisms (Henry Stapp, Donald Davidson, Thomas Nagel) and panpsychisms (David Chalmers, Philip Goff, John Leslie). Under normal circumstances both of these theories would count as metaphysical, that is not physical theories at all! They are physical not logically, but merely by ancestry. Purportedly they remain physical (or physics grounded) because their novel (never specified) qualities can only have originated in the big bang!

Dual-aspect monisms make the claim that physics is incomplete in the sense that there are additional fundamental properties in micro-physics not yet (and perhaps never to be) discovered. The physical in this view includes the mental in a proto-property form. This undiscovered addition is not conscious; atoms are not aware. Nevertheless the qualities of this extra-physics direct event unfolding towards that which yields consciousness. Working backwards from consciousness, this channeling must also encompass the preconscious stages of life’s evolution and the origin life throughout the universe. To our empirical experience, only life, some life, becomes conscious, and that only as it gains the right sort of complexity following millions of years of evolution.

If dual-aspect monism of any sort was true however, we would expect its effect to show up in the equations describing the regularity of physical evolution. There is no such term in the equations of macro physics so to say that this extra aspect of the physical is a part of physics surely begs the question.

This is why I think so many philosophers grasp at quantum dynamics to locate proto-mental qualities. We cannot directly measure quantum phenomena until they interact with the macro physical world, and quantum phenomena, technically, are not random but indetermined. Perhaps (so they speculate) we can locate the proto-mental in the difference between ‘random’ and ‘indeterminate’, in effect shielding teleology from possible detection? But surely a proto-mental is not the only possibility accounting for the restriction from random to indeterminate (see note on this distinction at end of essay).

Furthermore no one (physicist or philosopher) has been able to say what properties the proto-mental has, how they restrict random to indeterminate, or how the indeterminateness of the quantum phenomena we know push the macro universe towards consciousness. Even Henry Stapp’s “Quantum Zeno Effect” addresses only the narrow interface between brain and the human type of consciousness. Even if this speculative connection turns out to be a measurable phenomenon, no one has suggested how the physical world accommodates it. They all seem to agree that the proto-mental cannot be conscious in the sense that we experience it, but that tells us nothing of what properties it does, or even might, have and how they work!

What all of these theories entail however is that the mental (the proto-mental at least) must be antecedent to the physical! If it has a downward influence on the physical, which these views entail, it has to be ontologically real! Where does it come from? If the foundation of the universe is physical, what is it in or of the physical that grounds the proto-mental? The idea of a proto-mental here is not incoherent by any means. But it’s coherence largely depends on there being something about the fundamental ontology of the universe that isn’t physical! Moreover something that directs with intention!  Teleology is here introduced something the more honest of the philosophers admit they cannot seem to avoid.

For these reasons, dual-aspect monisms violate CCP(2) but they also violate CCP(3) because whatever else the extra might be it is clearly teleological. Instead of the universe ending in one state or another driven only by contingent process, the extra-physics channels evolution toward a specific outcome! It is therefore purposeful in the sense of being goal-directed.

Panpsychism is the converse of dual-aspect monism. It isn’t that mind builds up particle by particle thanks to some undiscovered property of particle physics, but rather it is the universe taken as a whole that comes to embody the extra physical qualities. Philip Goff (in a paper) neatly distinguishes two forms of panpsychism, micro and cosmo versions. Micropanpsychism is much like dual-aspect monism. The mental is attached to physics at the particle level but it isn’t effective except as contributor to a totalizing affect of the cosmos. Micropanpsychism has dual-aspect monism as a foundation but asserts that its impact is felt only in relation to the whole universe. You might think of this like neurons and brains. Every neuron in your brain is a foundation of brain functionality. But mind doesn’t show itself other than at the level of the whole brain, or at least large parts of it. In Micropanpsychism, the properties of the whole emerge from properties of the parts.

Cosmopanpychism abandons the dual-aspect foundation and asserts it is only the universe as a whole that reveals proto-mental properties. This view needs no micro-alteration to physics. Mind emerges from brains the way stars emerge from gas clouds because special properties of the totality, properties described by laws parallel to those of physics, are able to invoke it. Somehow, the entire universe acquires properties (usually not taken to be conscious as such) that come to direct physical evolution, and then biological evolution, towards consciousness.

This idea clearly violates CCP(3) (it is teleological) but is precisely an attempt to avoid violating CCP(2).  It is unsuccessful because the panpsychist claim is essentially that from the total state of the universe there emerges a parallel collection of qualities (properties and laws) that evoke mind from brains!  At one level or another, physics results in non-physics and so violates CCP(2). Besides Goff, David Chalmers is a proponent of this view.

For the cosmopanpsychists the “mental qualities” do not (typically) amount to the emergence of a literal Cosmic Mind, a “thinking universe”. Such a view would amount to substance dualism at the level of biological mind! But the philosophers who assert this do not, with one exception that I know of, specify what any of these properties are. As is the case with all the other theories, none of the qualities that supposedly effect the transformation nor any part of the mechanics of their interaction with the other-than-mental are anywhere given.

The exception here is John Leslie who asserts the property or quality characterizing this emergence is goodness. We normally think of goodness as a quality of the character of persons and so, by extension, of their minds. Emerging with the big bang is not only purposeless physical mechanism, but a parallel quality of goodness. A universe pushed in that direction is so pushed because goodness is a quality of it from the beginning, and mind is good!

To get the job done, any of these extras must, necessarily, be effective. It does no good to say that something besides the physics we know, something that is nevertheless physical (or quasi-physical), might or might not push cosmological evolution towards life and life towards consciousness. If the operation of these extras is itself contingent then what would be their point? To do the job they must not only have the necessary power, but that power must result in their goal-directed effect. The extra-in-physics, its goal-directedness, must be logically antecedent to the physics we measure that does not, in any aspect, appear goal-directed.

Where does antecedence come from? Since all of these philosophers are materialists, it must originate, with everything else, in the big bang. But there is nothing in the physics of the big bang that contains anything of the mental, anything of this extra there, and certainly nothing to which we can point that bears value; goodness. The big bang is a quintessentially physical event. What is  the proto-mental property in physics? How does it arise from within an other-than-mental physics and yet be logically antecedent to physics?

The extra-in-physics, under any of these approaches, hangs, metaphysically, on literally nothing! In John Leslie’s view, not only is universal mechanism goal directed, it is also moral! For him, morality happens to pop into the universe with the big bang and it is this quality that underlies drift towards the mental. How, presumably in the absence of any mind, has this direction become good? Even if it is, how does goodness effect the direction of physical contingency?

Does physics itself have an analogous problem with this last point? Where does the physical universe come from? Why is there any physics at all? Physicists have an out. They have the quantum vacuum which, while purportedly physical, cannot in principle be directly probed. This boundary layer between physics and nothing insulates physics. As concerns physics itself, and anything it gleans of quantum phenomena, the CCP is not violated. It is for this reason, I think, that so many philosophers reach for the quantum straw. We have already seen that this move is ad hoc. Moreover it goes against that which we have discovered about quantum behavior. No “mental term” is needed in the equations of quantum mechanics any more than in macrophysical equations, and goal-directedness is not implied by any of our multiple quantum interpretations.

To be fair, many of the philosophers who propose the solutions outlined above recognize that these suggestions violate the CCP. All claim (often citing Occam’s Razor) that violating the CCP is less onerous than supposing there is, for example, a God who knows the trick of making all of this work out the way it has. Working out a way, that is, for purposeless physical mechanism, mind, and even libertarian free will, to coexist in the universe. What troubles me about these philosophers is their refusal to admit that these problems (what brings about cosmological mental properties. How precisely do they interact with physics) are in some respects more mysterious than God! At least God can be supposed to “know the trick”.

Perhaps in the greatest twist of irony,  many of these minds have thrown up their hands and returned to idealism, abandoning the CCP entirely! Not only is the mental logically antecedent to physics, it is ontologically prior! The above mysteries are resolved because mind causes physics and not the other way around! The irony is that, in essence, this is what theism has claimed all along! I should not need to point out that in God’s absence, the metaphysical ground, prior to physics, of the mental is unfathomably mysterious!

How does a “God hypothesis” avoid violating CCP(1) with particular regard to free will? Doesn’t a genuinely (libertarian) free will entail (as Sean Carroll has put it in “The Big Picture”) that “mind causes physics”? In a narrow sense yes, theism violates CCP(1) but theism has an out. Mind is presupposed after all and constitutes the one exception to CCP(1) in the universe! The Theist is free to change CCP(1) to read: “physics comes only from physics and mind”. This move doesn’t help the physicalist because for her, the issue is the emergence of mind from physics without presupposing mind. They can, of course, say that mind is the only exception to CCP(1), but that surely begs the question, there not being any other evidence that physics can do this.

The change to CCP(1) is not circular in Theism. Yes mind is an exception. It is in truth a cause of physics. But here mind is presupposed. CCP(1) is not violated because mind doesn’t emerge only from physics. The exception, that part that evokes subjective experience from brain activity, comes not from physics but by some indirect route from God. It must be indirect (I do not believe God personally manages emerging individual minds) because God is changeless while mind, individual mind, changes with time. Mind’s direct source (besides brains) must be inside time.

Theism does not violate CCP(2) because physical mechanism still produces only physics. The result of mind-producing-physics, say the movement of my arm, remains physical. Theism does not violate CCP(3) because physical mechanism remains perfectly purposeless. Purpose as such remains entirely in mind. Notice that CCP(3) does not say that the physical universe has no purpose, only that the local operation of its mechanism (macro and micro)  is purposeless.

The goal of this essay has been to argue that nontheistic notions of mind’s emergence (or lack of existence) have problems equal to or exceeding the problematic aspects of theism. Let’s review.

God is a fantastical being. Positing his existence demands at the least an addition to what physicists take to be the only ontology of the universe; the physical. A God hypothesis demands that this entity has the power and knows the trick to producing the physical as well as causing minds to arise from the physical work of brains and interact downward with the material world. This mystery cries out for a physical explanation; at least a suggestion of what it is about the physical that makes that connection. Theism does not supply this physical answer, but nor does physicalism or any of the extra-physical theories covered above.

On first blush, the extra-physical ideas demand less addition to our fundamental ontology. The physicalist theories demand, if not technically an addition to ontology, at least that the physical can do that which no observation, no experiment, has seen it do; bring about something nonphysical. The extra-physical theories do demand a new, non-material addition to ontology. It isn’t God, but yet it must have the power to bring life and then mind about. Not only must it have this power, it must surely succeed. If the emergence of consciousness remained contingent and might not have happened the extra-physical qualities of the universe would be redundant. Further, any direction, anything other than absolute contingency, implies a teleology that has to be antecedent to the physics it influences!

The atheist philosophers who hold such theories recognize that they do move partway towards God (at least a Deistic version of him). In effect they are a “functional God”. But if there is no real God, then in what, metaphysically speaking, do any of these properties cohere? If you add to this stand-in the property of “having purpose”, and to backstop an infinite chain of prior cause, being first (and so uncaused) cause, you pretty much have gone all the way to God. In the end, the purely physicalist theories are nonsensical because mind is both prima facia obvious and non-physical. The extra-physical theories, if they do not need all the qualities of an “Abrahamic God”, require enough of these properties (non-materiality, purpose, antecedent cause) to be equally fantastical! When, in addition, you accommodate the problem of these mysterious properties emerging, literally from nothing, you end at a full-blown God concept that is at least deistic if not fully theistic.

Note on the distinction between ‘random’ and ‘indeterminate’

The distinction is important in quantum mechanics (I believe) because quantum phenomena come out in a well known and repeatable probability distribution even though there is no reason, no cause that we know of, why they should not be actually random. An electron could, theoretically be anywhere in the universe but there is a 99.9% probability that it will be found in bounded range of locations.

Here is a mundane macrophysical example I hope captures the idea. Imagine a fair six-sided die. Any face from 1 to 6 can come up with equal probability. The die is random within the confines of possibility (even an electron cannot be outside the universe). Now suppose you have a heavily-loaded die in which two sides, 1 or 6 are likely (and repeatedly) to come up on 90% of the throws, but within that 90% a 1 or a 6 are equally likely. That die is no longer random, but it is indeterminate.

 

Review: The Order of Time by Carlo Rovelli

By sheer coincidence I published the essay, “What is Time”, shortly before reading Carlo Rovelli’s book. Rather than writing additional commentary here, I put a pointer to that essay. While it does not address Rovelli directly (I hadn’t read him yet) it covers the points made in the review included below. But I do not want to discourage people from reading this excellent book. It is always good to understand the arguments of authors with which you (in this case I) happen to disagree. One cannot claim to be a well rounded philosopher without understanding what it is that those you disagree with are saying.

The Order of Time by Carlo Rovelli (2018) Amazon review

Like consciousness, time is a subject that no philosopher or physicist has ever managed to nail down completely. Thanks to their slippery character, being so close to us (the first one IS us) they are endless sources for fountains of speculation. In this book, Rovelli’s subject is time, but consciousness comes into this narrative as well.

Rovelli is a “time denier”. OK, that’s being a little unfair but not by much. What he denies is that there exists an independent, fundamental property or quality of the universe that is time. Of course the universe is full of movement and change, events unfolding into other events. His basic position is that time emerges into our perspective, our viewpoint, from these phenomena, but it is merely an illusion. The movement is real, the changing is real, but the time in which all of this seems to occur is nothing more than a manifestation of human (possibly animal) mind and the illusion, in turn, is supported by the entropy generated in the functioning of our brains.

The book (not long read) is divided into three parts. In the first Rovelli covers the various sub-disciplines of physics and their temporal implications (or lack thereof). He begins with classical physics (the equations work backwards in time), and moves on to General and Special Relativity, and quantum mechanics. Here he demonstrates that our simple intuition of a universal time flowing from past to future is untenable. Time, mind-independent time, if it exists at all, cannot be like that. In part two he further demolishes time. Not only is it not what we think, in and for physics, it doesn’t really exist at all; even the present is an illusion! In part three, he puts time back together for and in the perspective of an subjective viewpoint.

He argues it is the fact that we view the world from a perspective, that when we perceive the world we inevitably blur the details into a sort of summary or gestalt for our perspective, that causes time to appear to mind, The physics supporting that appearance comes down to thermodynamics. Human time, brain time, is “thermal time”. Certainly Rovelli thinks thermodynamics (in particular the 2nd law) is real, but while responsible for what consciousness perceives of time and so a real enough subjective experience, from the 3rd party perspective of physics, change is real, but time is a mirage.

This book is written for a lay audience. There is almost no math in it (what there is appears in footnotes), and it defends a view common to much of the physics and philosophy community. To be sure Rovelli differs a bit from some of his peers. He argues that relativistic “block time” is no more a “true portrait of objective time” than any other theory. In Rovelli’s view remember there is no such thing as “objective time”.

In 2015 a philosopher (Roberto Unger) and a physicist (Lee Smolin) wrote “The Singular Universe and the Reality of Time”. This book (reviewed by me on Amazon) makes precisely the opposite case from that of Rovelli. Of course they recognize what Relativity and quantum mechanics imply about time, but they maintain, nevertheless, that a notion (and reality) of objective, “universal time”, is more fundamental than any other phenomena of the universe, even more than space! Rovelli mentions this book in a footnote and admits that Unger and Smolin’s view “is defensible”, but he leaves it there and never addresses what is defensible about it.

The Unger/Smolin book goes against the grain of 95% of today’s physicists. Personally I agree with Smolin and Unger. The fact (thanks to limiting effect of the speed of light) that we cannot map our present to any present in a remote galaxy, or even the nearest star does not mean there is no present there, in fact everywhere. Something is happening, NOW, everywhere in the universe. We do not know what it is, but that does not mean the present isn’t real as Rovelli believes. Had Rovelli directly addressed Unger and Smolin I would have given this book another star. Had he not mentioned them at all, I would have taken another away.

In summary this is a decent and well written book advocating for a particular view of time (or no time) that I happen to think is wrong, but what do I know? It happens to be the dominant view in physics today. Rovelli is a well respected physicist and a good writer. Those of you interested in the subject will find this book valuable whether you agree with the author or not.
