For Every Theist there are One Hundred Materialists

selfie

As concerns philosophy of mind, for every theist, there are one hundred materialists in the present-day philosophical community. Theism, purportedly has many problems, but it does do a nice job explaining the seemingly qualitative difference between subjective experience (that is, mind) and the perceived (and purportedly) mind-independent world. I will return to theism at the end.

Among materialists, for every eliminative materialist (as concerns mind) there are five pure property dualists. For every property dualist, there are ten Russellian monists of one stripe or another and a like number of panpsychists. These last two categories often overlap with some versions of Russellian monism (sometimes called dual-aspect monism) becoming panpsychism at larger scales. There are also monisms that do not become panpsychism, and panpsychisms that do not rest on monisms. While materialist philosophers of these various philosophies of mind talk to one another about the differences in their theories (each intended to overcome specific problems seen in their competitors), none of them ever mention their over-arching issues, problems that all of these various theories have in common. This essay is the result of my attempts to discuss these common problems with several of these philosophers all of which have been met with stony silence.

Each of these materialist approaches to mind is supposed to solve the “problem of mind” without reference to a Deity who would, should he exist, obviously have the power to create both the physical universe and mind within it. The starting point for all materialist solutions is the physical universe (that’s why they are materialisms), in particular “causal closure”. This fundamental principle comes down to the idea there is only physics in the universe and all the physics that now exists came from physics and nothing else. There is another axiom and a few corollaries to the causal closure principle. The other axiom is that only physics (besides being produced by only physics) itself produces only [more] physics. The corollaries are (1) nothing of physical mechanism is purposeful, or “there is no teleology in physics”, and (2) there is reciprocity in physical mechanism. A cause is always in someway changed by its effect. Physics recognizes two sorts of causes in the universe: macro-physical determinism, and micro-physical indeterminism. Both types of cause fully comply with causal closure, axioms and corollaries.

The central problem addressed in all of these theories (except eliminative materialism) is that consciousness, in particular human mind (though applies also to the higher animals), does not appear on its surface to be material at all. Yet mind does very much appear to be a cause productive of physical effects; the manipulation of some associated individual body. If mind emerges purely from physics, is nonmaterial in some sense, and a cause in the physical, then the causal closure principle as it stands is false.

ELIMINATIVE MATERIALISM

Eliminative materialism is the only PoM that does not entail some change to causal closure. Indeed, it does not suffer from any particular metaphysical issue (there being nothing needing any metaphysical ground), nor any problem with property specification or “interaction”, one or more of which, as we will see, plague every other theory including theism. The problem with eliminative materialism is that it achieves all of this by denying consciousness exists. It saves all of causal closure by claiming that consciousness does not belong in the list of real phenomena (ontology) filling our universe, making itself prima facia absurd! It is to overcome this absurdity (and at the same time avoid supposing an existential intentional source of mind) that all the other PoMs were invented!

PROPERTY DUALISM and EPIPHENOMENALISM

Property Dualism is almost always a basis of the other theories except for theism and even here there are sensible interpretations that are largely property-dualistic and not Cartesian substance or Thomistic hylomorphic dualism. Both monisms and panpsychism, at least in many of their interpretations, come out to mind of our sort being a property that emerges from brains. In pure property dualism, there is nothing other than the physics and biology of brains involved, that is causally closed physics as understood by most physicists. Yet in this view, the second axiom of physics, that physics produces only physics is seemingly violated. In one special case, the case of brains, physics produces something that while yet supervening on physical properties displays novel properties, a seemingly nonmaterial subjectivity, and with this the power to cause physics, to cause a physical change in the brain that results in the uncontroversially physical control of a body. This breaks the first causal closure axiom, and amounts to proposing a third kind of cause in the universe, mental-cause.

As with all of these theories there are variations. Some property dualists avoid proposing a third cause with a variation called epiphenomenalism. Here the idea is that consciousness, our subjective, seems real enough from within it, but as concerns the external world, its powers are purely illusory. Brains do produce consciousness, but consciousness does not “cause physics” (Sean Carroll “The Big Picture” 2016). Epiphenomenalism, however, while preserving the first causal closure axiom doesn’t save the second.

Pure property dualism doesn’t suffer from any particular metaphysical or property specification problem. Since mind comes only from brains there is no need for further metaphysical grounding and since only these brain-based minds are at all mental there is nothing to discriminate or specify as concerns the mental properties of anything other than brain-minds. Property dualism does have an “interaction problem”. As noted above causal closure is violated in at least one (epiphenomenalism), and often two directions.

How exactly does the new dualistic entity emerge from pure physics (we have found no other example of such an emergence), and how, by what means exactly, in its bi-directional variation, does it “cause physics” in turn? No one can say. Henry Stapp’s Quantum Zeno Effect is an interesting speculation (mind can partly-constrain wave function collapse in special micro-structures of the brain). QZE only pushes the problem up one level. It is a suggestion regarding what mind does to brains, not how it accomplishes this feat.

RUSSELLIAN MONISM and PANPSYCHISM

Both Russellian monisms (of various sorts) and panpsychism (also of various sorts) are, conceptually, advanced to suggest solutions to this mystery in pure property dualism. How does ordinary physics under causal closure come to have the extraordinary ability to produce something nonphysical and how does that entity come to have causal effect on the manifestly physical brain? Maybe physics isn’t as purely physical as physicists think. Maybe all they can detect and measure is the physical, but physical law has psychic or proto-psychic (I use these terms interchangeably throughout) qualities built into it? Whenever we measure the physical, we are measuring combined physical and proto-psychic qualities.

When brains come along, they produce mind as we know it because these psychic qualities somehow sum up in brains in a way that expresses them in what we experience as subjective consciousness. Supposedly this avoids violating causal closure because what physics calls causal closure already has the psychic built into it. Brains evoking minds are merely the culminating expression of these qualities.

This is, in essence, the core of both the monisms and panpsychism. One-way or another, either at the micro-level or the universe taken as a totality, psychic-potentials in the form of something positive attached to physics, add up to consciousness as we know it when brains come along. These qualities have to be positive. If they are merely potentials, possibilities, then they are no different from all other phenomena presently in the universe including galaxies, stars, life, and so on. All of them were obviously possible, made that way by the conditions of the Big Bang and the cosmological settings.

Yet while monisms or panpsychisms seem to resolve one issue, and not even that very well as we will see, they raise more than one of their own. Where do they come from? How is it “psychic-properties” pervade physics (or cosmology)? What is their origin? Physics, cosmology, itself has the quantum vacuum. There is all this material stuff and process in the universe because the quantum vacuum is unstable and the macroscopic universe, the Big Bang, is the result (see “A Universe From Nothing” Lawrence Krauss 2012). Importantly, the resulting galaxies, stars, planets, and all cosmological evolution at least up to the appearance of life, fall out of our physical equations given the measured cosmological settings. Getting all this requires no extra-influence, no psychic-qualities. Significantly, there are no extra [psychic] terms in the mathematical equations describing any of this.

Monists and panpsychists say the proto-psychic properties are brute, built-in to physics at the micro (monism) or cosmological (panpsychism) scale and what we measure as such in physical measurements already includes the proto-psychic properties. Yet, no psychic-placeholders are needed to represent physical phenomena in our equations. For cosmology, the properties of the big bang, including the values of the cosmological settings, are sufficient to ground (make possible), all of physical reality as we find it, including life. Life’s origin perhaps presents a special problem, but not a topic I will address here (See “Answering Five Questions: The Relation between Science and Religion”). Only mind seems to need something more. Something more that is than the possibilities inherent in pure physics. Other than this, the psychic properties, at any other level, are explanatorily redundant.

Another problem raised by panpsychism and Russellian monism are the properties of the proto-psychic. We can say something about what “psychic qualities” are for our own minds. They are the substance of our experience, our “what is it like to be” and include qualia and intentionality (our free capacity to direct our attention) among other properties. Yet except for a negative characterization “it isn’t that”, none can say anything positive about what these micro or cosmological psychic properties actually are. They are not consciousness. So what are they? Nor can anyone answer the related question: what do these psychic qualities do exactly to physics? How would physics be different if they weren’t there?

The retort here is that these qualities are what they are such that when material organization becomes dynamic and complex enough, subjectivity, mind, emerges. This is after all the reason these speculations exist. But if these psychic properties have no effect on physics until complex brains evolve, this solution becomes ad hoc. If brains are utterly contingent (as pure physics has to claim) then they might not have ever evolved. That being the case, psychic properties in the micro physical or cosmological would have had no purpose what-so-ever, more explanatory redundancy.

On the other hand, perhaps the psychic qualities we cannot describe do something long before life and brains come about. What? They would act in such a way as to push physical evolution towards strengthening the likelihood of otherwise contingent evolution to produce life and eventually brains! If this is the case, then to be clear, teleology, purpose, is put back into physics, the purpose, in this case, of evolving minds! Now we are face-to-face with some purposeful mind behind all of this, or we must accept that, purely by accident, there is attached to physics that which cannot be detected, comes from nowhere (the Quantum Vacuum doesn’t help here), and happens by sheer chance to push cosmological and biological evolution towards mind.

All of this though begs again the question of the mechanism of this influence. A self-respecting chemist will scoff at the notion that any process, even one as finely tuned as a living being or a brain does anything, on the purely physical level, but satisfy the physical equations. Any influence the psychic has would have to be invisible to what pure physical theory addresses perfectly well, for example selecting mutation X over the equally likely mutation Y. Since no such influence can be detected, we face again, although the devoted will object, a manifestly nonphysical phenomenon (except by stipulation that it must be physical because there is nothing else) that has some effect in (and on) the physical. We have, in short, an “interaction problem!”

In short, philosophers put up a placeholder that supposedly explains the capacity of the material world (at the micro or cosmological level) to invoke consciousness from brains, but can say nothing positive about this placeholder. They cannot say how it happens to exist or where it comes from. They cannot describe any of its properties, they cannot say how it manages to work, how it interacts with physics. On top of all this the theoretical edifice must either add teleology back into physics and cosmology or it is explanatorily redundant until brains happen, contingently, to arrive on the scene!

THEISM

Theism is the notion that some minded and purposeful entity, God, exists and has the power to spawn the physical universe by some mechanism (perhaps the big bang), and purposefully direct its evolution towards life and mind. Under theism, there must be a purpose to otherwise purposeless physical mechanism. Since God is purportedly infinite (eternal) and uncaused-cause (unique in the universe [of which the physical is but a part] having no prior-cause), postulating him puts a stop to infinite-recursion of causes.

Theism has an inverse counterpart to Eliminative Materialism, Berkeley-ian style “pure idealism”. The idea is that nothing is real except mind, our individual mental arenas. What “appears to mind” as the external world from the inanimate to other persons, even our own bodies, is put into our minds by God. This idea is not as prima facea absurd as eliminative materialism. It accepts mind, at least my own mind (idealism can drift towards the solipsistic), as obvious and since God is infinite he has the capacity to do exactly what idealism claims he does.

Idealism is even less popular than eliminative materialism because God is needed to make it work. But it has other problems. For example, why should this mind of ours find, what amounts to a simulated mind-independent world, so complicated? It is one thing for God to put a virtual tree outside my virtual window, but as I further explore the tree I discover incredible complications. Not only the tree’s cells their macroscopic (deterministic) intricacies, but all the rest down to quarks and the Schrödinger wave equation. Doesn’t all of this amount to God deluding us about what seems to be a reality independent of mind even if recognized only from within it? For these reasons the preponderance of evidence favors a genuine, mind-independent, world whose properties we discover through application of mind.

A good God would not be in the business of deluding us. If there seems to be a mind-independent world, and if, with mind we appear capable of grasping its intricacies, then evidential experience suggests the mind-independent world is real. At least at middle size scales (roughly dust motes to mountains) there is a remarkable correspondence between the world and its representation in mind.

Besides idealism there are two well-known theistic PoMs, Cartesian-style substance dualism and Thomistic (Aquinas) hylomorphism, the first being much better known than the second. I do not believe either is satisfactory. Hylomorphism is vague about what exactly is formed, or what mind is a form of or in. Cartesian substance dualism has never given enough credit to brains. For Descartes, mind, being immaterial, should in theory be able to float free of any particular instantiation. Why is mind associated always and only with brains?

My own view is closely related to materialistic property dualism adding a catalyst that evokes the nonmaterial mind from the activity of brains. The catalyst (Cosmic Mind, perhaps a poor choice of names) is not mind as such and combining the two (brains and catalyst) is required. For more on this and how it differs from Cartesian dualism see “From What Comes Mind”. My interest here is how theism in general compares with the materialistic theories as concerns their metaphysical issues: origins, teleology, psychic qualities, and the interaction problem.

Regarding origins, brains are physical and come up an evolutionary chain. The catalyst comes, in one-way or another by some direct of indirect route, from God as does the physical universe within which evolution occurs. God, being eternal-uncaused-omnipotent, has no particular metaphysical problems of his own granting his existence for the sake of argument. The question “from whence comes God?” is answered. God comes from God.

The relation between the teleological and causal closure, a problem for panpsychism and Russellian monisms is also solved. Causal closure in physics is true. Mechanisms in the physical are well and truly purposeless. At the same time God has, seemingly, a purpose for purposeless physical mechanism. Universe physical outcomes, governed by the conditions of the big bang and the cosmological settings, do not merely allow for life and later mind, but were intended, deliberately, to deliver them over time. Even if Cosmic Mind has no teleological role before the appearance of brains (I do not assert this to be true, but my argument does not hang on its truth) it is not redundant (as are proto-psychic properties with no teleological impact) because the eventual appearance of brains is not, under a theistic view, contingent.

The description or properties problem, acute for panpsychism and the various monisms, is not an issue for theism because there are no proto-psychic qualities to describe! Stars, rocks, and thermostats have no proto-psychic qualities, nor does the physical universe as a [physical] totality. The equations of physics need no proto-psychic term because there are none to apply. Nothing is psychic until brains evolve and then the interaction between Cosmic Mind and brains evokes subjective consciousness. Notice that this not only includes animal brains, but supports exactly the hierarchy of consciousness that we find on Earth. Lower-order brains have lower-order consciousness. There is something it is like to be a bat, and something less to be a lizard, and less still a fish, and so on. Cosmic mind, uniform throughout the universe, invokes mind only to that level the underlying brain makes possible.

This then brings us to the interaction problem. Theism does little better here than panpsychism, Russellian monism, or for that matter both two-way property dualism and one-way epiphenomenalism. Every PoM apart from eliminative materialism suffers from the same interaction problem! Even so, theism does a little better than the others. Nobody can say how any of these theories (their implied ontologies) work to evoke mind from brains, but theists can say, at least, there is someone who knows the trick. Further we have no reason to suppose that this trick of God’s is comprehensible to the minds invoked by it.

It does no-good for the Russellian monists or panpsychists to argue that they have no interaction problem because the claimed “proto-psychic” properties are built-in to physics and so physical by stipulation. This move is part of the whole point of these theories but it is disingenuous, merely pushing the lump to another part of the rug. The proto-psychic presumably has some impact on what would happen in the physical. Physics would presumably come out differently in its absence. Without being able to say what this impact is, how physics differs thanks to these properties, and merely stipulating that they are physical without distinguishing them from a physics without them, makes them explanatorily redundant.

Of the three problems, metaphysical ground, property specification, and interaction, theism resolves two and makes sense of our epistemic incapacity to resolve the third — God’s powers are beyond our ken. The gap between mind and the doings of the physical brain is intrinsic to the nonmaterial character of mind and the causally closed qualities of physics. Mind cannot be directly probed from the third person perspective, and from the first person, its own origin is phenomenally transparent.

Theism gives something additional that all the various alternative solutions never address directly, free will! Free will is the elephant in the consciousness room (see “All Will is Free”). Pure property dualism can only scratch its head about its appearance, its power, seemingly automatically embedded in mind. Panpsychism and the monisms do accommodate its possibility, but offer no clue as concerns its origin or mechanism. Theism grounds free will.  A free intentionality is possible and exists because a free intentionality with the relevant power put it there, the integral facet of our subjective experience (a truth ironically recognized by atheistic Schopenhauer). It turns out there is a point to everything after all (see “Why Free Will”)

Meanwhile, the PoM consequences of theism fit experience. Why does the evolution of mind in the universe seem to be something more than purely contingent? The intuition is true, mind was intended. Why is mind alone, within a teleology-free physical mechanism, purposeful (intentional)? Because the source of both mind and physics is intentional, minded.  Why does consciousness appear nonmaterial from its own viewpoint and invisible from the viewpoint third parties? Because the catalyst (Cosmic Mind) is not material, but in mind of the biological type, the nonmaterial is grounded in all three of the “fundamental joints” in reality (see “Prolegomena to a Future Theology” and “Why ‘One Size Fits All’ Ontologies Never Work”).

I could go on and others of my papers explore some of this from different perspectives. The point here is that Theism answers questions and resolves ontological and epistemic mysteries much better than do any of the non-theistic PoMs. In fact, these theories leave everything out! Their only reason for existence is to reject theistic explanations. There cannot be a God, so what then supports mind? Is it mysterious proto-psychic properties that have no discernible origin or metaphysical ground that we can find or even speculate about, no properties we can say anything about, and suffer from the interaction problem they were stipulated to avoid?

Of course philosophy must be free to speculate about experiential phenomena from any perspective whether theistic or atheistic. My problem with the atheists in PoM is not that they advocate for their ideas, but in my extensive reading not a single one acknowledges any of the fundamental problems I have here raised. What happens if the proto-psychic is subtracted from physics? Materialists can say only that, while the cosmos would look much the same, mind would never appear. Even if brains evolved, the creatures animated by them would be David Chalmers’ P-Zombies! By contrast, if God were subtracted from the universe, there wouldn’t be any universe at all, but rather nothing. This outcome is philosophically advantageous. It is this common origin of both mind and physics that grounds the metaphysical possibility of their interaction. No, we cannot fathom the interaction mechanism, but under materialist PoMs even the possibility of the proto-psychic is left unexplained.

Review: Philosophy of Mind by Edward Feser 2006

One would expect a book on this broad subject to leave some dangling issues. Dr. Feser’s sympathies clearly lay with Aristotelian dualism, even theism. He begins with a nuanced statement of Cartesian Substance Dualism. His aim is to explicate the logical strength of substance dualism, aware also of its primary weakness (the “interaction problem”) and then ask if the various alternatives to it, particularly those promulgated by materialist philosophers of the 20th and 21st centuries, are coherent in their own right and if so, successfully defeat dualism’s logic.

As noted in the review (reproduced below with a link to the book on Amazon) Feser spends the bulk of the book on this latter task. He demonstrates that none of the suggested alternatives actually work. Some (eliminativism of two kinds and epiphenominalism) are incoherent, while others (functionalism, behaviorism, and many others) fail to capture the substance of subjective first person experience, in effect explaining it away. Most of these critiques focus on epistemological issues, but some also run into metaphysical issues, indeed the same “interaction problem” faced by Cartesian dualism (see also “From What Comes Mind” and “Fantasy Physics and the Genesis of Mind”).

Having demolished the contenders, Feser asks if there is something else, a different sort of dualism that might work and yet not require or point to theism? His solution is Aristotelian Hylomorphic dualism. Alas, as noted in the review, here he fails but doesn’t seem to notice it. Either the form emerges from the facts of the assemblage that is the brain, or it is added intentionally from the outside. Hylomorphism either collapses into reductive (or supervenient) materialism, or it leads back to something that must stand in the place of, if not be, God. Feser leaves this matter dangling.

Other issues dangle. Feser cites many authors I’ve read, among them David Chalmers, but as I read Feser, he seems to misunderstand Chalmers’ “property dualism”, more or less equating it with epiphenomenalism,  the idea that our mental arena is merely an accidental by-product of brain function with absolutely no causal consequence. It is precisely the point of Chalmers’ property dualism that it does have causal consequence and so is not epiphenomenal but rather a radical emergence.

From the physics of brains alone emerges what amounts to a substance with novel properties, the upward property of subjective experience itself, and a downward causal power, subjective will, on that same physics. Chalmers, being bothered by the radical character of the emergent subjectivity, speculates on panpsychism or various types of monisms that might be embedded in physics and so support such an emergence (see above linked “Fantasy Physics…” essay for details). These various ideas for sources of the phenomenal in a hidden property of the physical are quasi-material in Feser’s taxonomy.

Another matter of interest to me is Feser’s characterization of substance dualism. His sketch is more nuanced than that usually given by his materialist peers but there are other possibilities that yet remain broadly Cartesian. For example, a property dualism supported by the presence of a spacetime field that is not physical but also not phenomenal (or proto-phenomenal).

The field need not be mind as such. It need have no phenomenal/proto-phenomenal properties of its own. Viewed from the material, mind is a radical emergence (upward) and has, as a result of its novel properties, also downward causal qualities. Its appearance, however, its form and nature, is the result of an interaction with this everywhere present (and yes, mysterious) field and not equally mysterious undetectable properties embedded in physics. For a detailed explication of this model see my “From What Comes Mind?”

Of course an “interaction problem” comes immediately forward. This hypothetical field is, after all non-material. But this interaction issue is the same faced by property dualism generally along with panpsychism, and Russelian or dual-aspect monism. All of these theories propose proto-phenomenal properties embedded in micro physics or the universe as a whole, but none ever say how exactly to identify the proto-phenomenal, in what exactly its properties consist. Nor do they speculate on their origin, and how they interact with the physical we know; how exactly they perform their teleological function driving the physical towards [genuinely] phenomenal expression.

Feser notes that materialist philosophers always cite “Occam’s Razor” as reason for rejecting theism and so any sort of substance dualism. He should somewhere have noted Occam’s Razor is supposed to apply to two or more theories that equally explain all the data! Theism answers two of the questions left dangling by quasi-materialisms. It explains why it is we find the phenomenal, any phenomenal proto or otherwise, only in association with brains. It has also an origin story in theistic intentionality, the phenomenon we find at the core of the recognizably phenomenal, our phenomenal, itself!

Quasi-materialisms deny intention in the proto-phenomenal leaving the transition to intention in brains hooked (metaphysically) on nothing. None of this, not the postulation of a field or the proto-phenomenal explains how exactly interaction occurs. The problem with theism isn’t merely the interaction (about which at least “God knows the trick”) equally suffered by all the non-eliminative materialisms. The problem is the postulation of an intentional source of the field supporting intentionality as we experience it. Yes this is a big pill to swallow, but without it we can say nothing about how any of this works anyway. Rejecting the possibility of theism leaves behind more mysteries than it resolves.

Surely suggesting that there is an intentional (minded) source of intentional, subjective mind begs the question. Of course it does! It remains, however, a coherent, possibility! God can not only be conceived, his necessary qualities can be specified to considerable detail (see my “Prolegomena to a Future Theology”). It isn’t clear that the proto-phenomenal can be conceived, and even if we allow its conceivability there seems to be nothing that can be said at all about any  of its qualities.

I said at the end of the book review I would say something about free will. Feser does not mention it. Free will is related to intentionality. The ability to direct our attention purposefully is the core of the matter and some (Schopenhauer) would say it, is the essence of the conscious self! “Mental causation” or in Rescher’s terms initiation is, when not subconscious, agent-directed. We experience our agency as will (and this why the ‘free’ in ‘free will’ is redundant’ see “All Will is Free”). Will’s  relation to “philosophy of mind” should be obvious. We experience our volitional agency in mind, and like qualia and intention, the nature of volitional agency is mysterious, doubly so because it is a mystery on top of a mystery!

I have said much about free will and its associated agency elsewhere in the blog. On the negative side (the absurdity of denying it) see “Arguing with Automatons”, and “The Nonsensical Notion of Compatibilism”. On the positive side, “Why Free Will”, “Why Personality”, and “The Mistake in Theological Fatalism”.

The two best books on the subject are “Free Will: A Philosophical Reappraisal” by Nicholas Rescher and E. J. Lowe’s “Personal Agency”. My own books, “Why this Universe” and “God, Causal Closure, and Free Will” both address the subject.

 

Philosophy of Mind by Edward Feser (2006)

I picked up Feser’s “Philosophy of Mind”, a book in an introductory series, for the sake of little else to read at the time, but I’m glad I did. It is, perhaps the best basic-evaluation of this subject (one of my specialty areas) I have ever read. It doesn’t merely introduce and review the subject. It makes an argument, a point about the present philosophical state-of-the art on the nature of mind, and does it very well.

Feser begins by introducing the subject and settles on representative-realism (the external world is real more or less as we experience it, but what we experience as subjects is nevertheless a representation of it) as the fundamental datum which a philosophy of mind must account. He then moves to examine the various proposals put forth by modern philosophers, some with their roots back in classical Greek times. He begins with Cartesian (substance) Dualism, a rather more sophisticated treatment than is usually accorded by modern philosophy. He shows us that substance dualism rests on more solid logical foundations than is usually acknowledged even if it smacks of being unscientific thanks to its infamous “interaction problem”.

From that point Feser looks at what has been offered as alternatives to Dualism, various materialisms (eliminative, functionalism, behaviorism, pure epiphenomenalism, causalism, reduction and supervenience) and quasi-materialisms (panpsychism, Russelian-monism, property dualism). All of this treatment constitutes the bulk of the book and as he covers each solution there emerges the best taxonomy of philosophies-of-mind I have yet seen. The modern emphasis on qualia is explored thoroughly but he argues that intentionality, even given the representational realism with which he begins, is more important, more central to mind and consciousness, than qualia.

In doing all of this Feser drives home the point that none of the alternatives is without serious metaphysical or epistemological problems. All of the quasi-materialisms, in fact, come up against the same interaction problem as substance dualism, and the others are either incoherent (two sorts of eliminativism), or simply do not get at two core problems: why do we experience anything at all and why does the subject that appears throughout all experience seem so obviously causally potent?

In the last chapter Feser asks if there is anything else that does address the core issue without having to invoke what ultimately comes down to God? His answer is Aristotle’s “Hylomorphic Dualism” (also championed by Thomas Aquinas though his variation relies directly on God). To explain consciousness, to get at its core and resolve the ever-present interaction problem, Feser says all we have to do is reject the contemporary physicalist insistence that material and efficient causes (two of Aristotle’s four leaving out formal and final cause) exhaust causality in the universe. This would be, to say the least, a big pill for 21st Century science, and most of philosophy, to swallow.

Further while Hylomorphic dualism might deal nicely with the epistemological issues Feser everywhere touches, it does no better than the quasi-materialisms concerning the metaphysical. Either the form of the human mind springs entirely from the arrangement and dynamics of physical particles, in which case we are back to reductive or supervenient materialism, or it does not. But if it does not, where does it come from? That physics cannot detect any teleology in the physical universe does not mean it isn’t there. It does mean that it has to come from somewhere other than physics and be prior to individual human minds. We are on the way back to God.

There is also a notable absence. Feser never mentions free will. A discussion might be beyond Feser’s scope in this book, but I’m surprised he did not at least note its obvious relation to intentionality. I will cover this and other implications in a blog commentary.

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.

Comments on “Mind” by John Searle

In a wonderfully written book, “Mind” (2004 — see my Amazon review here) John Searle introduces us to issues in the philosophy of mind and promotes his own version of a theory of mind. While carefully rejecting present views of dualism (substance and property versions), and a larger set of variations grounded in materialism. He proposes his own view grounded, in the end, in materialism, but claims to avoid all the problems with other versions. What makes his version materialistic is that he assumes both the necessity and sufficiency of brains to be causally responsible for consciousness, that is agent subjectivity and intentionality. In large part, it is because of the causal relationship that presentation to consciousness via sensory experience, and causal action by an agent who can “make things happen” that the “interaction problem” (the “mind-body problem”) largely disappears in Searle’s philosophy of mind.

But it never completely disappears. Searle runs into problems with free will and personal identity that the theory fails to accommodate. Free will does fit into his view of mind as it relates both to the individual and the collective. It has “conditions of satisfaction” that can be easily specified in Searle’s terms. Personal identity is far more problematic. I discuss both below.

While the necessity of brains to consciousness is these days not controversial, Searle’s assumption of their sufficiency begs the question in the debate between dualists (particularly substance dualists) and materialists, including Searle. It is precisely the point of the debate here that no one has established sufficiency of brains to minds, and it turns out the whole debate turns on what evidence there might be that brains are insufficient. It turns out the evidence, not proof, comes from physics itself; the causal closure principle!

Searle implicitly recognizes this “begging of the question”. At the end of chapter 4, having said that he belives his arguments fully refute the various materialist variations he explores, he says this about dualism.

“Notice that these arguments still leave dualism as a logical possibility, though I think extremely unlikely, that when our bodies are destroyed, our souls will go marching on. I have not tried to show that this is an impossibility (indeed I wish it were true), but rather that it is inconsistent with just about everything else we know about how the universe works and therefore it is irrational to believe in it.”

I do not believe he really “wishes it were true”. If he did, he might have found a more sophisticated version of the argument (see  also “From What Comes Mind?”). He also says, in the same conclusion to chapter 4 that as goes the two ontological realms (the mental and the physical), “No one has ever succeeded in giving an intelligible account of the relationships between these two realms”. Part of the purpose of this essay is to give such an account consistent with his structural analysis of mind. In the end, the precise mechanism of the connection remains a mystery, but in my view, it is no longer a connection between realms. One problem is that by “how the universe works” Searle is speaking of the discoveries of science, starting with physics. In physics, there simply is no evidence of any positive reality added from elsewhere (besides brains) that could constitute consciousness some separate thing added to physics. Physics finds no other realm and that is certainly true! There is no other realm that physics can possibly detect. But for physics to declare, blithely, that “nothing other than physics exists” obviously begs the question, something even physicists (those not pushing some vested interest) admit. This blatant assumption impacts both substance and property dualism.

Property dualism is a materialism where brains are necessary and sufficient causally, but what they cause comes, inexplicably, to take on a being of its own. Property dualism says that a new ontological realm emerges from physics, and once emerged has independent properties that are ontologically objective and yet remain interactive with physics. Property dualism springs from materialism and either proposes a new, fundamentally different ontology springing (who knows how) from the material, or it falls into epiphenomenalism. The core of this view falls into the same trap as many nondualistic (materialist) explanations, the naked assumption that “nothing but physics” is manifesting any such ontologically novel realm.

As for substance dualism, Searle refers explicitly to a strictly Cartesian version. In this variation, God in some direct way imposes mind on bodies. Brains are not even directly involved, although even Descartes recognized that some connection must exist between them. This view leads to all sorts of distractions (souls, disembodied minds) that are not, in fact, entailed even by a “mind realm”. Searle believes the whole idea of an ontologically objective “mental realm” (substance or property) is the root of dualist problems and he is right, but for some of the wrong reasons. His reasons stem, mostly, from belief expressions that come down to us through the history of religious institutions. These beliefs are vague and confused and may not properly distinguish between mind, soul, person, or spirit. All this vagueness was present in Descartes, and everyone (dualist or anti-dualist) since Descartes has simply imported it into their idea of what dualism must entail. Property dualism of course looses the disembodied soul notion but still comes out to an ontologically objective “realm” that brains produce. I agree with Searle, this is the wrong way to look at it.

There are more sophisticated versions of a proper substance dualism argument, but it remains the case that some of what is substantial about substance dualism has to come from something that is itself nonmaterial. This typically ends in God because that is what humans have thought must ground anything nonphysical. Once you have God, the physical too becomes grounded, and the fact of interaction between whatever it is that constitutes the mental and the physical is no longer a surprise. Nevertheless, the mystery of the interaction mechanism remains. But we need not go as far as God to paint a more sophisticated substance dualism; we can start with physics. The principle of causal closure stated briefly is that physics comes from and produces only physics. Subjective experience, being in its essential nature nonphysical, cannot emerge from physics, at least not physics alone!.

Consider a radio, powered up, properly functioning, playing some music. The music issues from the proper functioning of the radio in a way analogous to subjective mind’s issuing from our brains. Clearly the music (technically pressure waves of a certain type) is not the radio itself. But there is no music realm, only music which stops (or becomes distorted) the moment the radio stops functioning properly. Note now the properly functioning circuitry of the radio is 99% responsible for the music, but not 100%. There is something else, in this case a physical electromagnetic wave, that carries information to which the circuitry of the radio is (through a complex convolution of electron perturbation) sensitive. The important point here is the music is not merely added to the radio the way Descartes added mind to body. That is why, in the case of the music, there is no realm. The radio is responsible, the cause, of the music, and brains are similarly the cause of consciousness.

Consciousness is not added to brains, but stems from them. However, the radio while necessary is not sufficient to produce any music at all without the information bearing (and electron perturbing) radio wave to which its functioning circuits are sensitive. The music (strictly speaking the configured pressure wave) is the expression of that sensitivity transformed through the radio’s circuitry. Something to which the brain is sensitive results in a metaphorical interpretation we experience literally as experience. There is no realm because mind as such is not added from the outside to brains. Mind, subjectivity, springs from brains in response to or as a result of (transformed by brain circuitry) sensitivity to something nonphysical that must, nevertheless, exist inside the physical universe.

We must posit something, we need not go all the way to God, existing inside (is a part of) the physical universe that has three qualities. 1) It cannot itself be physical. 2) it must be able to affect brains, or put another way, brains must be sensitive to or detect this something. 3) it must be everywhere in the physical universe such that where ever the right circuitry comes to be in the universe, a subjective experience, attached to that circuitry, appears in or rather as some subject. This “hybrid-substance dualism” says this: Consciousness emerges from brains. Consciousness is not added to brains from the outside but emerges in functioning brains themselves in conjunction with or as a result of (causal) interaction with some entity that is not itself material.

Why not material? Because the material alone, the brains, cannot invoke the nonmaterial which is the essential characteristic of a subjective awareness! This is my core assumption, and I justify it not by religion but physics! No physics has demonstrated the emergence of a nonphysical phenomenon from nothing but physical forerunners (causes). It is also a fact that the only seemingly nonphysical phenomenon we know is consciousness, subjectivity, itself. Given what it is physics is competent to explore, the physical, and that we have a manifestly nonphysical subjective experience that is clearly reliant on brains, the only legitimate assertion physics can make about mind is that we cannot possibly know if physics is sufficient to produce it. This does not prove “physics doesn’t produce it”, but it also gives us no justification to say that it does.

In both of my books and a few essays here on the blog I call this entity “Cosmic Mind”, but that has the unfortunate connotation that it is itself a thinking entity or that it amounts to panpsychism. Neither is the case. Perhaps a better name might be “Cosmic Mind Field” (CMF). Existing in time and pervading all space. It is nevertheless not a panpsychism because it evokes consciousness only in brains, not rocks, individual living cells, or thermostats. But it must function as a field (albeit not electromagnetic) because it performs where ever functioning brains are present and evokes a continuum of consciousness from brains of varying levels of complexity.

Perhaps there is “something it is like to be a fish or a lizard, but we have good reason to believe that whatever that is, the consciousness of lions, apes, and parrots is richer, and that of humans richer still. Like two radios of different quality, the more primitive brains invoke a more primitive and limited consciousness in the same way the lower quality radio reproduces less of the information present in the electromagnetic wave.

This picture allows Searle’s view of consciousness to go through. Brains being causal entities evoke consciousness. There is no mystery of “causal mind” because brains do all the causing. Searle’s analysis of “aspectual intentionality”, qualia (aspectual perception), belief, desire, the subconscious, and so on all can go through as he supposes they do. My proposal avoids the Cartesian “realm business”. Mind is not some realm imposed on bodies, but stems from them. At the same time it resolves the causal closure dilemma. Mind is nonphysical because its invocation from brains isn’t entirely physical but depends on the brain’s sensitivity to the CMF.

But what is that exactly? It is precisely because the only handle we have on objective (mind-independent) ontology is perceptual and therefore physical that we cannot say. We cannot detect the CMF with physical instruments, nor conceive of any experiment that would isolate it from other phenomena because we can only so isolate physical phenomena! CMF sensitivity is common to all consciousness. There is nothing that we have from within consciousness that isolates the effect of the CMF because consciousness is that effect. But human consciousness at least effects a partial escape from this. I will come to that a bit below.

The Free Will Problem

In Mind Searle runs into two problems he cannot fit into his analysis, free will and personal identity. As concerns free will Searle admits he cannot reconcile even a causally efficacious consciousness with free will on the brain side. On the psychological side, from within subjectivity, he cannot shake the conviction that free will must somehow be genuine. We presuppose it in everything we do and every utterance we make. Does my model help us here? I could always say that free will is just a power (more in man than in fish) that consciousness has. Searle would rightly object that this doesn’t explain anything new. It doesn’t explain the ontological ground of the freedom. How in a universe of random (quantum) and deterministic phenomena does anything (even the nonmaterial) become free in the volitional sense?

This is both a physical and a metaphysical problem. It’s hard enough to accept that physics alone is sufficient to cause consciousness. Now it also happens that this consciousness is volitional, its choices neither determined nor random (both purposeless) but now directed and purposeful? The CMF is becoming extraordinary indeed.

The metaphysical issue is not merely the possibility of volition in the universe, though that is one issue. Like consciousness, free will must be possible as its exercise supports our entire intentional state. As with consciousness, free will’s possibility is something physical law makes room for. What physical law demands is that physical causal chains have some physical starting point. Physics allows its macro-deterministic behavior to arise from randomness, the quantum vacuum. If physicists were being honest, they could not rule out that something else, something not visible to scientific method, can also start causal chains.

Volitionally initiated causal chains, the causal part, all begin with some macro-physical starting point; for example the motion of a hand or a speech act. They are not causal chains until that point. But physics cannot preclude that, perhaps simultaneous with neural activity, a volitional act neither determined nor random, initiates that chain. It is, in other words, logically possible that physics alone is not enough to explain the appearance of a third source of causal chains; volition. Not only is this logically possible, physics itself recommends the conclusion. In centuries of sophisticated experiments and observation physics has found only determinism and randomness. Why should physicists concede the possibility of a type of cause they cannot, even in principle, detect? Because unlike other hypothetical entities (ghosts) and powers (remote viewing), free will is presupposed in virtually every decision we make as human beings. Volitional capacity is the closest thing to “obvious in our experience” besides experience itself. Not only must we presuppose it, our entire culture, language, art, institutions, cleverly designed experiments, and engineering feats, all imply free will.

In “Making the Social World” (2011) Searle devotes a chapter to language and the commonalities and differences between pre-linguistic and linguistic mind. He lists five possible types of “linguistic utterances”: Assertives, Directives, Commissives (e.g. promises), Expressives (e.g. apologies), and Declarations (e.g. “I pronounce you husband and wife”). The first four of these all have pre-linguistic forms (beliefs, desires, intentions, and emotions respectively) but Searle says that Declarations, making something real (e.g. a married couple) merely by declaring it, has only a linguistic form. Searle does not recognize that free exercise of will is precisely a pre-linguistic declarative. It “makes something real” by willing it, and has the same “two directions of fit with the world” as declarations.

One freely chooses (Searle’s “prior intention”, “will-to-world fit”, “world-to-will” cause) and then freely acts (“intention-in-action”, “world-to-will fit”, “will-to-world” cause). The “conditions of satisfaction” for free will are the same, indeed a combination of, those of perception and action, homologous to linguistic declarations. If I think I am free, that belief can only be true if I really am free. If I act freely and introduce into the world a new [physical] causal chain that action is satisfied only by a genuinely new causal chain initiated by a free choice. If this analysis is correct, then free will is a property of consciousness in the same sense as intentionality and the CMF must, in some sense be its metaphysical ground.

The Identity Problem

Searle demurs on free will’s “ontologically objective” reality, but he cannot bring himself to do the same for agent-identity. To be conscious, to have purposes, to choose, are, in human experience, the consciousness, intentionality, and volitional elections of an agent. All of our experience presupposes agency, some singular identity that recognizes the change all around it by reference to its constitutive changelessness. Searle doesn’t use the word ‘changeless’, but his examples are telling.

He shows that memories do not explain the phenomenon. There is an image in my mind from when I was two. I believe it is real because my parents explained to me once what it was when I was a little older. But then there is a gap and the next memories (few) I have are of events taking place when I was four. Gradually, the gaps become smaller and the number of memories grows, but gaps persist here and there even to recent times. And yet, I have the unshakable conviction, as much as the conviction that a persistent “I”, the same person, have existed since that earliest memory.

I had that memory and I have all the other memories, the same I despite gaps in the memory record spanning years! What about the future? I can plan for a future, say going to graduate and postgraduate school to become a philosopher. I can act today so eight or ten years from now I, the same I who today applies to graduate schools, becomes a philosopher. Looking backwards from that time, I will be the same person who filled out those first applications. I will recognize this. If my brain has functioned normally throughout that time, its truth (reality-representation) is immediately apparent. The “conditions of satisfaction” for changelessness are met.

Searle believes it necessary to posit some functional entity that stands for this “I”. He does not hesitate to declare that it cannot be a substance, but something must stand antecedent, logically anterior, to consciousness itself. As we experience it, agency is inseparable from our (that is human-subjective) exercise of will. Both the freedom and the will in “free will” seem, in our phenomenal arena, to come from, to be the will of, my agent-self, my “I”.

Is Searle’s “functional entity” helpful here? What does it mean for a functional entity to be changeless? How does this property emerge in a universe where everything else from physics to thought is constantly in flux? How does a functional entity dependent in some necessary sense on both a changeable brain and changeable consciousness gain this quality? Searle’s suggestion is merely a stand-in, but the qualities it must have suggest more.

Functions are processes. A changeless process is logically impossible. The agent can only be a substance whose persistence, at least, is logically possible. If that is the case agency cannot take origin in mind. The always-changing cannot produce changeless substance any more than physics alone can produce nonmaterial mind. Agency is always experienced and expressed in mind, but its metaphysical source must be external to it.

It is this substantial agency that makes possible the capacity to partially escape otherwise transparent subjectivity, something it appears only humans can do. By this I refer to our capacity to analyse mind itself. Lions have some sense of individuation from the world, but do not exhibit any ability to think about their consciousness as such. Only humans do this, and while language seems to be necessary in the exercise of this capacity it isn’t sufficient for its appearance. Even though what we experience of our own identity is experienced only in and through mind, only the existence of something in someway distinct from mind can provide a sort of “binocular perspective” that enables us to say something about mind itself, to describe our subjectivity (to ourselves or others) as if, as it were, from a third person perspective. I have much more to say about this in my essay “Why Personality”.

 

Putting it All Together

Both free will and identity raise extraordinary ontological issues. For mind, it seems an extraordinary coincidence that this CMF happened to be around to evoke consciousness from a certain organization of matter, especially as both the consciousness and the life on which it rests were contingent. Not only is the CMF implicated in consciousness (which at least we can suppose is generated by brains as music is generated by the radio), but also volition, something for which physics and philosophy cannot even account for logically let alone physically!

Identity is even more remarkable. It is one thing to suppose that some nonmaterial reality can arise out of the purely physical. It is even more of a stretch to demand that an entity that never changes in time arises in a time-drenched universe in which everything else changes! The absurdity of these impossibilities ends in two extreme positions, denial that nonmaterial phenomena exist, including consciousness, or that its existence must be purposeful. This is to say the antecedent presence of the CMF, is not an accident, but produced for the purpose of causing consciousness with free will when the right material organization comes along. Of course this has further teleological implications.

Searle insists that all explanations find their ground in physics, material reality, but he is left with three problems resulting from this demand; the mind-body problem, free will, and timeless agency. Starting with consciousness as such we have Searle’s assertion that it is just “what brains do” but he knows his explanation does not cross the gap. Dual-aspect (Russellian) monisms (Davidson, Nagel) or panpsychism (Chalmers, Goff) also fail to bridge the gap. If, as these philosophers insist, mind is nothing more than an expression of undiscovered physics then we should find evidence in physics for the emergence of something (besides mind which begs the question) even minimally nonphysical.

My own solution, the CMF, doesn’t get to the details either, but it explains why what we seek is not found in physics. It isn’t there. If the CMF and brains interact (which they seem obviously to do) then either we are back to impossible physics, or there is a third entity responsible for both. When we discover interaction between two otherwise discontinuous phenomena in the physical world we take this discovery to be evidence of some third phenomenon that mediates the interaction. In proposing such an entity, a common source of physics and mind, we are doing nothing new philosophically speaking.

The CMF makes consciousness possible, evoking subjectivity from brains, but by itself doesn’t give us free will. If free will, obviously exercised in and by mind, has a ground it must come also from our third entity. That entity must itself be willful, purposeful. It is reasonable to locate free will in mind, a power of consciousness, because its operation fits perfectly into Searle’s structural analysis of intentionality in language and both exhibit constraint by time. We choose only in the present and both the choices made and the conscious arena in which they take place are constantly changing.

But the same cannot be said of human subjective agency. This also exists in time and expresses in mind; I am here in the universe after all. But unlike everything else agency does not change. Our consciousness is always changing and our will (free or not) can act only in the present, but all this change takes place within a phenomenology of changeless self. This is such an extreme problem for Searle that he proposes a functional entity in some sense independent of both mind and physics. But just as we never see physics resulting in the nonphysical, it cannot yield up a changeless entity antecedent even to mind. Moreover, it is this agency that enables us to reflexively examine mind itself, something it could not do if it was not in ontologically distinct from mind.

Function resting on a constantly changing consciousness cannot be changeless. Unlike volition, changeless agency cannot be a product of the time-constrained CMF. Our antecedent and ontologically objective source must also be a timeless agency, able to add this agency to time-constrained mind. With this step we are all the way to a personal God outside time.

Granted this is a truncated argument. Searle is honest enough to admit that substance dualism remains logically possible but rejects it on the grounds that it adds nothing useful to the philosophy of mind. But Searle does not get any closer to the secret of subjectivity emerging out of physics alone other than to insist that it does. The dualism I propose takes nothing away from his analysis of the structure of consciousness as we experience it. My analysis of free will (above) shows that Searle’s basic insights about mind remain sound. Free will fits into his ideas about the relation of mind to language, better in fact than in his own analysis!

While not popular with physicists or philosophers, God, like dualism, always remains logically possible. Moreover, while theism does not explain the details, it does account for free willed nonmaterial agency outside physics. It tells us why physics cannot find these in physics itself but yet experiences (presumably in the minds of physicists and philosophers) them in a physical universe otherwise governed by deterministic process resting on the randomness of quantum mechanics.

That we have agency and do exercise free will is so obvious to me that I will make the extraordinary claim that what motivates most free will and agent denial is not physics as such which says only “physics cannot account for it”, but precisely that accepting the ontological objectivity of free will agency too easily opens the door to theism. Of course physicists and philosophers will greet this claim with derision but the fact remains that, in the end, only God can provide the ontological ground for both free will and agency.

 

Searle’s Quantum Mistake

In a chapter on free will (of the libertarian sort) Searle runs into something of a wall. He concedes that psychological freedom must be real, but he cannot reconcile this with what is ultimately physical biology (brains) both necessary and sufficient to produce consciousness, the arena in which psychological free will operates. He speculates on a popular suggestion, that quantum behavior, some quantum randomness essential to the brain’s function, is in some part responsible for a genuine (ontologically objective) volitional will. Searle knows that randomness is not volitional freedom, but he says that it is possible that something about the brain transforms the randomness into volitional freedom in agent consciousness.

But he doesn’t like this solution because it makes the brain different from all other organs in that only the brain requires quantum processes in its role. I believe he is mistaken here. There is good reason to suppose that life itself rests to some degree on quantum phenomena. Every bacterium, amoeba, or living cell in an organ of the body lives because quantum phenomena are an intimate part of the mechanics of living processes. The brain then would be no different from any other life in this respect though it may (I suspect does) further constrain (in Terrence Deacon’s sense, see “Incomplete Nature”) the quantum processes necessary for life. That is the brain utilizes quantum processes in some quantitatively or qualitatively “enhanced way” as compared to life in general, but it is no longer unique in its dependency on quantum process generally.

Suppose I am right here. Does it help us answer the free will question as concerns biology? No. There always remains the gap between physics and the subjective experience. How do “enhanced quantum constraints” become volitional, or for that matter subjective? The interaction problem always remains. But my suggestion does clear one of Searle’s objections to the involvement of quantum phenomena with the phenomenal experience of consciousness and free will; quantum processes are essential to life generally.

Review: After Finitude

My intuition tells me this will be an important book in the development of my own philosophical thought. It will prove important to my philosophy and theology although like all materialists, Meillassoux rejects theology as nothing more than “speculative metaphysics”. Yet he is brave enough to call what he writes here “speculative realism”, and it is speculative because his starting point is very much antirealist in orientation. Fundamentally an antirealist (he might disagree with me), he cannot know that he is correct. Like my theology (I cannot know that God exists), the evidence that Meillassoux is correct, is the result; his grounding of the insight that scientific discovery is about the world.

In my essay “Realism and Antirealism” here on the blog I note that “…one of the possibilities for explanations of experience in antirealism is realism.” This comment, made in a marginal note to Zizek’s “Less than Nothing” was made in the context of Zizek’s discussion of Meillassoux, and Meillassoux himself does not disappoint. The point of this little book is to recover realism, that is the genuineness of scientific insight into the nature of a world independent of experience, that there is a world independent of experience and that we can reliably have knowledge of it. Meillassoux achieves this with a very clever argument concerning the relation between necessity (there isn’t any except…), contingency (the only necessary thing about the world is that everything is contingent), and consistency — the reliability of the world’s regularities present to experience really is in the world itself and not merely in the “categories of our experience” a la Kant.

Meillassoux here is after nothing less than establishing a warrant for “scientific realism” on an antirealist foundation. As I note in my review below he doesn’t quite finish the job. He does manage to lay out all the elements of the argument and provide reasons for the validity of the assumption that science discovers truth about the world “as it is” in the absence of our experience of it even as he denies the validity of the Principle of Sufficient Reason, a principle “scientific realism” implicitly embraces. This is a singular achievement on his part. I’m glad I decided to read him.

Besides Meillassoux, there are two other philosophers who comprise the “New Realist” school Maurizio Ferraris and Graham Harman. I have reviews of both of them now with commentary comparing the three.

Quentin Meillassoux, “After Finitude” (Kindle edition 2013) Reviewed for Amazon

Meillassoux’s writing reminds me much of other top tier philosophers of the present day like E. J. Lowe (recently passed away), David Chalmers and a few others. Not in what he says of course his starting points and subject are different, but stylistically, carefully crafting his arguments and at each point stopping to describe and evaluate alternatives advanced by his contemporaries and historical predecessors. In “After Finitude” he begins, conceptually, with Hume and Kant, accepting with the latter that the proper starting point for philosophy is the world experienced by humans; what can be thought, but rejecting in both the idea that we cannot come to “know”, in the sense of rely-on experience, to deliver genuine insight into the world in itself.

Meillassoux rejects speculative metaphysics (mostly coming down these days to religion) and accepts the generally anti-realist notion that the Principle of Sufficient Reason, need not apply to the world apart from human experience of it, but holds that the principle of non-contradiction should not be abandoned. Even if we cannot conceptually embrace infinite possibility (totalize the world), it cannot be that the world contradicts itself. All of this comes down to there being no absolutes, no “necessary being” and no “thinkable totality of all possibility” except for the fact of contingency. The only absolute for Meillossoux is that everything is contingent and might have been other than it is.

But all of this leaves historical and present day (postmodern) anti-realists in the position of claiming that we cannot know anything beyond our experience at all, and it is this mistake that he aims to rectify. Despite his general acceptance of the Kantian starting point, he insists that the achievements of science over the last two centuries well demonstrate that we can discover (through an objectivity emerging from shared experience, the results of repeated observations and experiments) much that is true about the world of the past and the present even if such truth lacks the a priori assurance of mathematics.

That problem comes down to why, if it is correct to reject the Principle of Sufficient Reason for the world apart from human experience, the world, that is the laws of physics, seem to be so stable? If the history of the universe comes out to its not-necessary “facticity”, that it is the way it is merely by chance, why aren’t the laws and regularities constantly changing rendering our ability to comprehend anything, even to be conscious at all, impossible? Kant’s answer to Hume was that the stability is only the effect of the categories of our consciousness, and if the in-itself (Kant’s noumenon) were not stable there couldn’t be any consciousness in the first place. But Kant accepted the Principle of Sufficient Reason which Meillassoux rejects. Instead he points out than an unstable in-itself might appear stable for long periods (essentially an anthropic argument). Instability need not mean moment-by-moment instability.

Meillassoux argument rests itself on our ability to “mathematize” our shared experience. That we can describe phenomena in-the-world in mathematical terms and discover not only that 2+2=4 (a priori) but also that E=mc^2 (a posteriori) speaks to us of the world’s stability. But he never quite gets around to telling us how mathematics grounds the stability. Indeed I do not see how it can because if it did, that would render the world necessary.

But there is a further problem here. If instability were really a quality of the in-itself and the universe was infinitely (or trillions of years) old, a few tens of billions of years of stability would not be problematic. But if he is right about the meaningfulness of scientific discoveries, then the universe is only 13.8 billion years old and yet the laws have been stable at least since the moment of nucleosynthisis a second or so after the big bang. That means the laws have been the same for 13.8 billion years minus 1 second! Extraordinary stability indeed!

To sum up, a beautifully written book, well argued, a delight to read, with many insights into the relation between human experience (the for-us) and the antecedent (the for-itself) world. But it doesn’t quite finish the job, something Meillassoux says he must let go of (for now I presume) at the end of the book. A fantastic example of how good philosophy is done even if, in my humble opinion of course, he begins from the wrong starting point and never quite finishes.
