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 (the materialism often amounting to little more than stipulation) 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 which must (again often coming down to stipulation) be the only source of everything  else and the physical  is founded on “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 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 of mind (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. One or both of the axioms cannot be true.

ELIMINATIVE MATERIALISM

Eliminative materialism is the only PoM that does not entail some change to causal closure. Indeed, it does not suffer from any metaphysical origin 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 not-material phenomenon having certain properties emerging 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. The problem how mind interacts with physics (even if only for physics to manifest it)  is not resolved.

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.

In the end there is no stable position in the philosophy of mind between eliminative materialism and theism. Eliminative materialism is stable because it claims there is nothing what-so-ever to explain. Theism is stable because it self-grounding (God comes from God) and because it has the resources to do the job (explain why the universe is the way it is including mind and free will), even if the matter of how exactly that job gets done remains forever beyond our pay grade.
