Physicalist Christology? Notes on Merricks
"And the Word was made flesh, and dwelt among us . . . . (John 1:14)
Physicalism is popular among philosophers these days. So it is no surprise that Christian philosophers are drawn to it as well, including those who subscribe to the central teaching that God the Son, the second person of the Trinity, the Logos or Word, became man in Jesus of Nazareth.
Incarnation, whatever else it involves, involves embodiment. How is God the Son during his earthly tenure related to his body? Trenton Merricks assumes that "God the Son . . . is related to his body just as you and I are related to our respective bodies." ("The Word Made Flesh," 261.) One might have thought that the embodiment relation that connects the Son to his body would have to be very special or even sui generis; after all, the Logos is sui generis and so it might naturally be thought that any relation into which it enters would inherit that sui-generic quality. Merricks, however, assumes that divine and human cases of embodiment are cases of one and the same embodiment relation. The divine case is just a special case. Call this the Same Relation assumption. (My tag, not Merrick's).
And what relation is that? On physicalism, "You have a body if and only if you are identical with that body." (294) So the Same Relation assumption in conjunction with physicalism yields the conclusion that the Incarnate Son is "identical with the body of Jesus." (294) So in becoming human, the Incarnate Son "became [numerically identical to] a body."
This does not make much sense to me and I find it more worthy of rejection than of acceptance. My problems begin with physicalism itself.
Physicalism
The physicalism in question is not physicalism about everything, but about beings like us, minded organisms, if you will, which include all human animals. (If there are so-called 'abstract objects,' then they are not physical, and presumably before the Incarnation, no member of the Trinity was a physical object.) Physicalism is "the claim that each of us is a physical object." (294). Now there is a sense in which it is obviously true that each of us is a physical object, and that is the sense in which it is obviously true that each of us has a body; but one quits the precincts of the obvious and the datanic and enters the space of philosophical theories when one claims that one has a body by being numerically identical to a body, or that the the 'is' in 'Each of us is a body' is the 'is' of identity.
For this is not obvious. How do you know that the 'is' in 'Each of us is a body' is not the 'is' of composition? (Compare: 'Each of these statues is bronze.' That can't mean that each of the statues is identical to bronze or to a particular hunk of bronze. A statue and its proximate matter have different persistence conditions both temporally and modally.)
But we are discussing physicalism. I am not asserting that we are composite beings. And I am not espousing substance dualism either. I am merely considering whether physicalism about minded organisms is an intellectually satisfying position. Does it command our assent? Merricks thinks it is "pretty obvious" that physicalism is true. (294) I don't find it obvious at all. And as Hilary Putnam once quipped, "It ain't obvious what's obvious."
On physicalism, I am identical to the living, breathing, sweating animal wearing my clothes. Of course, I am not always sweating and not always wearing clothes; but if I cease breathing, I cease living and, on physicalism, I cease existing. (The physicalist claim is obviously not that I am identical to a corpse or an inanimate hunk of human-looking flesh and bones wearing my clothes.) To underscore the obvious, when I speak of identity I mean numerical identity.
One might find physicalism hard to swallow. If x and y are identical, then whatever is true of x is true of y and vice versa. That is necessarily so, and part of what we mean by 'identity.' But it is true of me that I am a "spectator of all time and existence," (Plato, Republic VI) whereas that is not true of my body. So I can't be identical to my living body. To take a less grand example, I am now thinking of a girl I used to know. So is my body thinking of her? The whole body? Some proper part or parts thereof? Presumably not the plantar fascia in my left foot. My brain? The whole brain? Some proper part thereof? How could any portion of the brain be the subject of acts of thinking? That doesn't make much sense. In fact, it does not make any sense. A bit of highly organized meat is the subject of acts of thinking in the broad Cartesian sense of 'thinking' which includes memorial acts? Are you serious?
Could it nonetheless be true that what thinks in me when I think is the brain or some portion thereof? I suppose, but then it would be a mystery how it is true. The Incarnation may be a mystery, but if we are trying to understand the Incarnation physicalistically, then physicalism had better not be a mystery too. I'll come back to this point below.
The obviousness of physicalism seems to have vanished. Merrick does not give the following invalid argument, but what he says on 294 ff. suggests it:
Whatever has physical properties is a physical object.
Socrates has physical properties.
Therefore
Socrates is a physical object.
Therefore
Physicalism is true.
The argument is rendered invalid by an equivocation on 'is' as between the 'is' of class inclusion and the 'is' of identity.
What I have said does not refute physicalism, but it does show that physicalism is far from obvious and does not follow from such Moorean facts as that you and I have shape and mass. So I balk at Merricks' "it seems pretty obvious that physicalism . . . is true." (294) It is not obvious at all.
Property Dualism
Can these objections be met by adopting property dualism? Merricks' view is that while we are physical objects having physical properties, we are not merely physical objects: we also have mental properties. "Persons also have mental properties." (295) Furthermore, these mental properties are irreducible to physical properties. Merricks tells us that his physicalism is consistent with property dualism. (295) I think it is fair to say that with respect to beings like us, he is a substance monist and a property dualist.
The idea is that the human individual having properties is a physical object, but that it has two different mutually irreducible sorts of properties, physical properties and mental properties. But how does this help? I am thinking about a girl I used to know, a particular girl, Darci. Is there a mental property corresponding to the predicate '___ is thinking about Darci'? I doubt it, for reasons I don't have ther space to go into, but suppose there is this strange property. Call it 'D.' Presumably it is an abstract object unfit to do any thinking. So it is not the subject of the thinking, that in me which thinks when I think.
Should we say that I am thinking about Darci in virtue of my instantiating of D? But who am I? On physicalism, I am identically this living body. So this animal body instantiates the mental property. But this brings us right back to our earlier question as to which part of the animal body does the thinking. Introducing a dualism of properties does not answer this question.
How Could a Non-Physical Object Become a Physical Object?
But even if physicalism is true, how could it, in tandem with the Same Relation assumption mentioned above, be used to make sense of the Incarnation, or rather the embodiment the Incarnation implies? How could the second person of the Trinity, a purely spiritual, nonphysical person, at a certain point in history become numerically identical to the body of Jesus? How could an immaterial being become a material being? I should think that an item's categorial status is essential to it. So if an abstract object such as the number 7 or the set of primes is nonphysical, then this object is nonphysical in all possible worlds in which it exists, and indeed in all possible worlds, full stop, given that 7 and the number of primes are necessary beings. If so, then in no possible world could the number 7 or the set of primes become a concrete item sporting causal properties and spatiotemporal locations.
Something similar holds for that necessary being which is the second person of the Trinity. Its purely spiritual, wholly nonphysical nature is essential to it. So, on the face of it, its embodiment in a particular human being cannot be understood as its becoming numerically identical to that human being. For then, per impossibile, it would have to quit its kind and become another kind of thing.
Rejecting Kind-Essentialism
Now the above is an obvious and obviously powerful objection to which Merricks makes a daring response. He recommends rejecting the kind-essentialism that is at the back of it:
Believers in the Incarnation must reject kind-essentialism. Once kind-essentialism is rejected, it is hard to see why the non-physical God the Son could not become [numerically identical to] a human organism. Perhaps this is the sort of thing that might not seem possible merely upon reflection, given no relevant revelation. But the same thing goes for God the Son's becoming human. This is the mystery. (296)
I don't follow the reasoning here. Let us assume that we accept as revealed truth that God became man in Jesus of Nazareth. And let us assume that the Incarnation is, as Merricks says, a mystery. Now faith seeks understanding. Fides quarens intellectum. In this case we want to understand how God became man. How is understanding helped by the rejection of what appears to the unaided intellect as obviously true, namely, kind-essentialism? Is its falsity supposed to be a mystery too?
If I want to understand the Incarnation, I have to use principles that to the unaided discursive intellect appear secure. If I use the Incarnation to reject kind-essentialism, which is one of the principles that appear secure to the finite intellect, then I haven't made sense of the Incarnation; I have wreaked havoc on the discursive intellect. Would it not be better simply to rest with the Incarnation as mystery and forgo desperate attempts to make sense of it that violate very secure principles that are arguably definitive of finite understanding?
Why Not Reject the 'Same Relation' Assumption?
Suppose one wants to retain one's physicalism about humans at all costs and to accept the Incarnation as well. Would it not be better to jettison the 'same relation' assumption? Would it not be better to say that embodiment in the divine case is a different relation from embodiment in (merely) human cases? Suppose that in the merely human cases, to have a body, i. e., to be embodied, is just to be a body, i.e., to be identical to a (living) body, while in the divine case to have a body is something else, something perhaps incomprehensible to us in our present state. One could then be a physicalist without rejecting kind-essentialism.
Note that Merricks is not a physicalist about God or any of the persons of the Trinity prior to the Incarnation. He does not hold that every mind is physical. He makes an exception for the divine mind. Well, then he can make an exception in the way a divine mind becomes embodied should such a mind become embodied.
There seems to be two ways to go for one who aims to accept the Incarnation while also accepting physicalism about minded organisms. Accept either package A or package B:
Package A
Incarnation; physicalism; 'same relation' assumption; rejection of kind-essentialism.
Package B
Incarnation; physicalism; 'different embodiment relation' assumption; acceptance of kind-essentialism.
I should think that Package B is the more attractive of the two.
Merricks' paper is here. Many thanks to Professor Andrew M. Bailey for uploading it! Ditto to Kevin Wong for drawing my attention to it and for supplying me with a bibliography of recent work on physicalist Christology. Mr. Wong is a gentleman and a scholar!
Thinking Meat?
Question: Is it my brain that feels and thinks when I feel and think?
Argument A. Meat can't think. My brain is meat. Therefore, what thinks in me when I think is not my brain.
A in Reverse: What thinks in me when I think is my brain. My brain is meat. Therefore, meat can think.
The proponent of A needn't deny that we are meatheads. Of course we are. We are literally meat (and bone) all the way through. His point is that the res cogitans, that in us which thinks, cannot be a hunk of meat.
Both arguments are valid, but only one is sound. The decision comes down to the initial premises of the two arguments. Is there a rational way of deciding between these premises?
A materialist might argue as follows. Although we cannot at present understand how a hunk of living meat could feel and think, what is actual is possible regardless of our ability or inability to explain how it is possible. The powers of certain configurations of matter could remain hidden for a long time from our best science, or even remain hidden forever. What else would be doing the thinking and feeling in us if not our brains? What else could the mind be but the living and functioning brain well-supplied with oxygen-rich blood? The fact that we cannot understand how the brain could be a semantic engine, an engine productive of and sensitive to meanings, is not a conclusive reason for thinking that it is not a semantic engine.
It is worth noting that the reverent gushing of the neuro-scientistic types over the incredible complexity of the brain does absolutely nothing to reduce the unintelligibility of the notion that it is brains or parts of brains that are the subjects of intentional and qualitative mental states. For it is unintelligible how ramping up complexity could trigger a metabasis eis allo genos. Are you telling me that meat that means is just meat that is more complex than ordinary meat? You might as well say that the leap from unmeaning meat to meaning meat is a miracle. Some speak of 'emergence.' But that word merely papers over the difficulty, labeling the problem without solving it. You may as well say, as in the cartoon, "And then a miracle occurs." But then it's Game Over for the materialist.
Our materialist would do better to insist that unintelligibility to us does not entail impossibility. Our inability to explain how X is possible does not entail that X is not possible.
My response would be that while unintelligibility does not entail impossibility, it is excellent evidence of it. If you tell me that a certain configuration of neurons is intrinsically object-directed, directed to an object that may or may not exist without prejudice to the object-directedness, then you are saying something unintelligible. It is as if you said that .5 volts intrinsically represents 1 and .7 volts intrinsically represents 0. That's nonsense. Or it as if you said that a pile of rocks intrinsically indicates the direction of the trial. (See The Philosophizing Hiker: The Derivative Intentionality of Trail Markers.)
No rock pile has intrinsic meaning or intrinsic representational power. And the same goes for any material item or configuration of material items no matter how complex. No such system has intrinsic meaning; any meaning it has is derived. The meaning is derived either from an intelligent being who ascribes meaning to the material system, or from an intelligent being whose purposes are embodied in the material system, or both.
Thus I am rejecting the view that meaning could inhere in material systems apart from relations to minds that are intrinsically intentional, minds who are original Sinn-ers, if you will, original mean-ers. We are all of us Sinn-ers, every man Jack of us, original Sinn-ers, but our Sinn-ing is not mortal or venial but vital. Intrinsic, underived intentionality is our very lifeblood as spiritual beings.
So if the materialist says that the brain means, intends, represents, thinks, etc., then I say that makes no sense given what we understand the brain to be. The brain is a material system and the physical, chemical, electrical, and biological properties it and its parts have cannot be meaningfully predicated of mental states. One cannot speak intelligibly of a voltage drop across a mental state any more than can one speak intelligibly of the intentionality of synapses or of their point of view or of what it is like to be one.
Of course, the materialist can pin his hope on a future science that understands the brain in different terms, terms that could be sensibly attached to mental phenomena. But this is nothing more than an empty gesturing towards a 'possibility' that cannot be described except in the vaguest terms. It is nothing but faith, hope, and hand-waving.
There is also the dogmatism of the materialist who insists that the subject of thinking must be the functioning brain. How does he know that? He doesn't. He believes it strongly is all.
So I give the palm to Argument A: Meat can't think. My brain is meat. Therefore, what thinks in me when I think is not my brain.
I do not absolutely foreclose on the abstract possibility that there be thinking meat. For I grant that unintelligibility to us is not invincible proof of impossibility. But when I compare that vaguely described abstract possibility with the present certainty that matter as we know it cannot think due to the very unintelligibility of the idea, then the present certainty wins over the abstract possibility and over the faith and hope of the materialist.
If you need to pin your hopes on something, pin them on the possibility that you are more than meat.
Conscious Experience: A Hard Nut to Crack
This is an addendum to Thomas Nagel on the Mind-Body Problem. In that entry I set forth a problem in the philosophy of mind, pouring it into the mold of an aporetic triad:
1) Conscious experience is not an illusion.
2) Conscious experience has an essentially subjective character that purely physical processes do not share.
3) The only acceptable explanation of conscious experience is in terms of physical properties alone.
Note first that the three propositions are collectively inconsistent: they cannot all be true. Any two limbs entail the negation of the remaining one. Note second that each limb exerts a strong pull on our acceptance. But we cannot accept them all because they are logically incompatible.
This is one hard nut to crack. So hard that many, following David Chalmers, call it, or something very much like it, the Hard Problem in the philosophy of mind. It is so hard that it drives some into the loony bin. I am thinking of Daniel Dennett and those who have the chutzpah to deny (1). But eliminativism about conscious experience is not worth discussing outside of the aforementioned bin.
Sophistry aside, we either reject (2) or we reject (3). Nagel and I accept (1) and (2) and reject (3). Those of a scientistic stripe accept (1) and (3) and reject (2).
What I didn't do in my original post was to state why a Nagel-type answer is better than a scientistic one.
Why not just reject (2)? One way to reject it is by holding that some physical processes are essentially subjective. Consider any felt sensation precisely as felt, a twinge of pain, say, or a rush of euphoria. Why couldn't that felt sensation be identical to a physical process transpiring in one's brain?
Here is an argument contra. Not every brain event is identical to a conscious experience. There is a lot going on in the brain that does not manifest itself at the level of consciousness. What then distinguishes those brain events that are conscious experiences from those that are not? There will have to be a difference in properties. But if the only properties are physical properties, taking 'physical' in a broad sense to include the properties mentioned in physics, chemistry, electro-chemistry, and so on, then there will be no way to distinguish between conscious and non-conscious brain events. Since there is that distinction, conscious experiences cannot be identical to brain events. (Don't forget: eliminativism has been eliminated.)
More simply, perhaps, the claim that a particular conscious experience is numerically identical to a brain event violates the Indiscernibility of Identicals. Necessarily, if x, y are identical (one and the same), then whatever is true of x is true of y and vice versa. Equivalently, if x = y, then x, y share all properties. (After all, if two putatively distinct items are in reality one item, then it is trivially the case that 'they' share all properties.) But conscious experiences and physical states do not share all properties. It could be true of a pain that it is bearable, excruciating, throbbing, non-throbbing, etc. But these phenomenal predicates cannot be true of a physical state such as brain state. Why not? Because physical states have only physical properties, and no phenomenal properties.
"But if the pain and the brain state are identical, then they must share all properties!" True, but which properties are those? The physicalist/materialist/naturalist can admit only physical properties. His aim is to reduce the mental (or at least the qualitatively mental) to the physical, but without eliminating the mental. That I claim is impossible. For again, conscious experiences are essentially subjective, as Nagel says, but there is nothing essentially subjective about physical states as physics and the related natural sciences conceive them. The materialist reduction doesn't work. Sensory qualia have not been show to be material in nature.
Going Mysterian
Someone who thinks that qualia just have to be material in nature might at this point go mysterian along the lines of Colin McGinn. The mysterian grants that we cannot understand how that twinge of pain or that sense of euphoria could be just a complex state of the brain, a pattern of neuron firings. But he insists that it is nevertheless the case. It is just that our cognitive architecture makes it impossible for us to understand how it could be the case. After all, if x is actual, then it is possible even if we cannot understand how it is possible. It is and will remain a sort of secular mystery.
In other words, the unintelligibility of the reduction of consciousness to matter is not taken as an argument against this reduction, but as an argument against our ability to grasp certain fundamental truths. Thus (2) and (3) above are both true and hence logically consistent; it is just that insight into this consistency is beyond our ken. What is unintelligible to us is intelligible in itself. In reality, my felt pain is identical to something going on intracranially; it is just that insight into how this is possible is impossible for us given how were are constructed.
There are problems with this mysterian way out that I may discuss in a separate post.
Two Ways of Referring to the Same Thing?
Another option for the materialist is to invoke the familiar idea that linguistic and epistemic access to one and the same item can be had in different ways, and that duality of linguistic and/or epistemic access need not be taken to argue ontological duality in that to which one gains access. Reference to one and the same item can be routed through different senses or modes of presentation. Different terms, with different senses, can be used to target one and the same referent. 'Morning Star' and 'Evening Star,' though differing in sense, can be used to refer to the same celestial body, the planet Venus.
Why not say something similar about the physical state I am in when I feel pain? Why not say that there are two ways of accessing the same physical state? The one mode of access is via neuroscience, the other is 'from the inside' via the pain's qualitative feel to the one who endures it. If so, there are not two states or events one physical and the other mental differing in mode of existence; there is exactly one state or event, and it is physical. Dualism is avoided. The upshot is that, contra Nagel, the third-person physicalistic approach to the mind does not leave anything out. One may go on to tax Nagel, Searle, and Co. with illicitly inferring a difference in mode of existence from a difference in mode of linguistic/epistemic access. Something like this objection is made by Christopher Peacocke in his review of Nagel's The View from Nowhere (Philosophical Review, January 1989.)
It's a nice try, a very nice try. And it is exactly what one would expect from someone who takes an objectifying third-person view. What's more, it would be in keeping with Occam's Razor if mind could be seamlessly integrated into nature. Unfortunately, the pain I am in is not a mode of presentation, or means of epistemic access, to the underlying brain state. Thus the Fregean analogy collapses. The sense of 'morning star' mediates my reference to Venus; but my pain quale, even if it is caused by the brain state, does not mediate my reference to it.
Let me see if I can make this clear. The suggestion is that the same physical reality appears, or can appear, in two different ways, a third-person way and a first-person way, and that this first-person way of access is no evidence of a first-person way of being. One problem is the one I just alluded to: there is no clear sense in which a pain quale is an appearance of a brain state. The former may be caused by the latter. But that is not to say that the pain quale is of the brain state. The felt pain does not present the brain state to me. It does not present anything (distinct from itself) to me. After all, the felt pain is a non-intentional state. No doubt it has a certain content, but not an intentional or representational content. One can describe it without describing what it is of, for the simple reason that there is nothing it is of. An intentional state, however, cannot be described without describing what it is of.
The Fregean sense/reference analogy therefore breaks down. The basic idea was that one and same reality can appear in different ways, and that the numerical difference of these ways is consistent with a unitary mode of existence of the reality. A felt pain, however, is not an appearance of a reality, but an appearance that is a reality. The appearing of a felt pain is its being, and its being is its appearing. And because this is so, the felt pain is a distinct reality from the brain state. Not only is it a distinct reality, it is a distinct reality with a distinct, irreducibly subjective, mode of existence.
Nagelus vindicatus est. There is something essentially incomplete about a third-person approach to reality. It leaves something out, and what it leaves out is precisely that which makes life worth living. For as Wilfrid Sellars once said to Daniel Dennett over a fine bottle of Chambertin, "But Dan, qualia are what make life worth living!" (Consciousness Explained, p. 383)
In vino veritas.
I conclude that if our aporetic triad has a solution, the solution is by rejecting (3).
Thomas Nagel on the Mind-Body Problem
Nagel replies in the pages of NYRB (8 June 2017; HT: Dave Lull) to one Roy Black, a professor of bioengineering:
The mind-body problem that exercises both Daniel Dennett and me is a problem about what experience is, not how it is caused. The difficulty is that conscious experience has an essentially subjective character—what it is like for its subject, from the inside—that purely physical processes do not share. Physical concepts describe the world as it is in itself, and not for any conscious subject. That includes dark energy, the strong force, and the development of an organism from the egg, to cite Black’s examples. But if subjective experience is not an illusion, the real world includes more than can be described in this way.
I agree with Black that “we need to determine what ‘thing,’ what activity of neurons beyond activating other neurons, was amplified to the point that consciousness arose.” But I believe this will require that we attribute to neurons, and perhaps to still more basic physical things and processes, some properties that in the right combination are capable of constituting subjects of experience like ourselves, to whom sunsets and chocolate and violins look and taste and sound as they do. These, if they are ever discovered, will not be physical properties, because physical properties, however sophisticated and complex, characterize only the order of the world extended in space and time, not how things appear from any particular point of view.
The problem might be condensed into an aporetic triad:
1) Conscious experience is not an illusion.
2) Conscious experience has an essentially subjective character that purely physical processes do not share.
3) The only acceptable explanation of conscious experience is in terms of physical properties alone.
Take a little time to savor this problem. Note first that the three propositions are collectively inconsistent: they cannot all be true. Any two limbs entail the negation of the remaining one. Note second that each limb exerts a strong pull on our acceptance. But we cannot accept them all because they are logically incompatible.
Which proposition should we reject? Dennett, I take it, would reject (1). But that's a lunatic solution as Professor Black seems to appreciate, though he puts the point more politely. When I call Dennett a sophist, as I have on several occasions, I am not abusing him; I am underscoring what is obvious, namely, that the smell of cooked onions, for example, is a genuine datum of experience, and that such phenomenological data trump scientistic theories.
Sophistry aside, we either reject (2) or we reject (3). Nagel and I accept (1) and (2) and reject (3). Black, and others of the scientistic stripe, accept (1) and (3) and reject (2).
I appreciate the appeal of the naturalistic-scientistic worldview and I don't dismiss it in the way I dismiss eliminativism about the mental:
Look, there is just one world, this physical world, and we are physical parts of it including all your precious thoughts, moods, and sensations. If you are serious about explaining consciousness, then you have to explain it the way you explain everything else: in terms of our best natural science. With the progress of science over the centuries, more and more of what hitherto was thought inexplicable scientifically has been explained. The trend is clear: science is increasingly de-mystifying the world, and it is a good induction that one day it will have wholly de-mystified it and will have cut off every obscurantist escape route into the Cloud Cuckoo Land of religion/superstition.
It is essential to see, however, that this worldview is precisely that, a worldview, and therefore just another philosophy. This is what makes it scientistic as opposed to scientific. Scientism is not science, but philosophy. Scientism is the epistemology of naturalism, where naturalism is not science but ontology. No natural science can prove that reality is exhausted by the physical, and no natural science can prove that all and only the scientifically knowable is knowable.
But it is not irrational to be a naturalist and a scientisticist — an ugly word for an ugly thing — in the way that it is irrational to be an eliminativist. But is also not irrational to reject naturalism and scientism.
And so the strife of systems will continue. People like me will continue to insist that qualia, intentionality, conscience, normativity, reason, truth and other things cannot be explained naturalistically. Those on the other side will keep trying. Let them continue, with vigor. The more they fail, the better we look.
Do those on our side have a hidden religious agenda? Some do. But Nagel doesn't. He is just convinced that the naturalist project doesn't work. Nagel rejects theism, and I believe he says somewhere that he very much does not want it to be the case that religion is true.
Nagel, then, has no religious agenda. But this did not stop numerous prominent, but viciously leftist, academics from attacking him after he published Mind and Cosmos. See the following articles of mine:
Should Nagel's Book be on the Philosophical Index Librorum Prohibitorum?
Mental Act Nominalism with an Application to Divine Simplicity
This entry continues a discussion with Dan M. begun here.
Before we get to the main event, a terminological quibble. A view that denies some category of entity I would call eliminativist, not nominalist. I say this because one can be a nominalist about properties without denying their existence. Tom is a tomato of my acquaintance. Tom is red and ripe and juicy and other things besides. It is a Moorean fact, I would say, that Tom has properties, and that, in general, things have properties. After all, Tom is red and ripe, etc. It's a datum, a given, a starting point. A sensible question is not whether there are properties, but what they are. Of course there are properties. What is controversial is whether they are universals or particulars, mind-dependent or mind-independent, immanent or transcendent, constituents or not of the things that have them, etc.
Still, there are those parsimonious souls who deny that there are properties. They accept predicates such as 'red' and 'ripe' but deny that in extralinguistic reality there are properties corresponding to these or to any predicates. These people are called extreme nominalists. It's a lunatic position in my view valuable only as a foil for the development of a saner view. But moderate nominalism is not a lunatic view. This is the view that there are properties all right; it's just that properties are not universals, but particulars, trope theory being one way of cashing out this view. My Trope category goes into more detail on this.
The present point, however, is simply this: a moderate nominalist about properties does not deny the existence of properties. So my suggestion is that if you are out to deny some category K of entity (i.e., deny of a putative category that it has members) then you should label your position as eliminativist about Ks, not nominalist about Ks. Dan is an eliminativist about mental acts, not a nominalist about them.
But this is a merely terminological point. Having made it, I will now irenically acquiesce in Dan's terminology for the space of this post. Dan writes with admirable clarity:
As you explain my proposal (I'll call it "Mental Act Nominalism" or "MAN"), an ontological assay of propositional attitudes will only turn up two entities, the agent and the proposition. The agent's having the relevant attitude (e.g., belief, doubt) to the proposition is not itself construed as an additional entity. You say that this view is committed to "a denial of mental acts and thereby a denial of the act-content distinction."
[. . .]
Turning to your concern. You suggest that "such a parsimonious scheme cannot account for the differences among" various propositional attitudes (belief, doubt, etc.). And after discussing some examples, you say they provide "phenomenological evidence that we cannot eke by with just the subject and the object/content but also need to posit mental acts." And you add: "The differences among [various attitudes] will then be act-differences, differences in the type of mental acts."
The gist of my reply is that we can perhaps account for the differences you speak of without committing ourselves to the existence of the relevant mental acts/states.
Consider these two situations:
(A) Dan wonders whether Bill owns cats.
(B) Dan believes that Bill owns cats.
(We may suppose there was a time lapse between them.) What should the ontological assays of (A) and (B) include? As you described MAN, its ontological assays of propositional attitudes deliver just two entities, the relevant agent and proposition. So on this approach, we get these two assays:
(A Assay 1) Dan, the proposition Bill owns cats.
(B Assay 1) Dan, the proposition Bill owns cats.
These assays fail to differentiate situations A and B. However, it's not clear to me that MAN has to be implemented in this way. Consider these alternative assays:
(A Assay 2) Dan, the relation wondering whether, the proposition Bill owns cats.
(B Assay 2) Dan, the relation believing that, the proposition Bill owns cats.
These assays do differentiate A and B, by virtue of the different relations. I think MAN is prima facie compatible with these assays, since the main aim of MAN is not to deny the existence of propositional attitude relations per se, but to deny the existence of mental acts or states consisting in the agent's having the relevant attitude. So, MAN must reject, for example, these assays:
(A Assay 3) Dan, the proposition Bill owns cats, the state Dan's wondering whether Bill owns cats.
(B Assay 3) Dan, the proposition Bill owns cats, the state Dan's believing that Bill owns cats.
So perhaps we can be realists about propositional attitude relations, but nominalists about propositional attitude states (of affairs). The former would give us a robust basis to differentiate different kinds of propositional attitudes, while the latter would preserve MAN.
BV: The issue is now one of deciding which tripartite assay to accept, mine, or Dan's. Where I have mental acts or states, he has relations. Mental acts are datable particulars, where a particular is an unrepeatable item. Dan's relations are, I take it, universals, where a universal is a repeatable item.
Suppose that Dan, who has not seen his elderly neighbor Sam come out of his house in a week, fears that he is dead. What does the world have to contain for 'Dan fears that Sam is dead' to be true? Suppose that it contains Dan, the relation fears that, and the proposition Sam is dead, but not the mental act, state, or event of Dan's fearing that Sam is dead. Then I will point out that Dan, the relation fears that, and the proposition Sam is dead can all three exist without it being the case that Dan fears that Sam is dead. The collection of these three items does not suffice as truthmaker for the sentence in question.
This is the case even if the relation in question is an immanent universal, that is, one that cannot exist instantiated. It could be that Dan exists, the proposition Sam is dead exists, and the relation fears that exists in virtue of being instantiated by the pair (Pam, the proposition Hillary is sad.) It is possible that all three of these items exist and 'Dan fears that Sam is dead' is false.
We need something to tie together the three items in question. On my tripartite analysis it is the mental act that ties them together. So I am arguing that we cannot get by without positing something like the particular Dan's fearing that Sam is dead.
How can a simple God know contingent truths, such as Bill owns cats? On the version of MAN that accepts bona fide relations, we say: God bears the relation believing that to the proposition Bill owns cats. There are just three entities to which this situation commits us: God, the relation, and the proposition. There is no state (construed as a bona fide entity) of God's believing that Bill owns cats.
BV: But if S bears R to p, this implies that R is instantiated by the ordered pair (S, p), and that this relation-instantiation is a state or state of affairs or event. It is clearly something in addition to its constituents inasmuch as it is their truthmaking togetherness. And this bring us back to our original difficulty of explaining how a simple God can know contingent truths.
Nagel on Dennett: Is Consciousness an Illusion?
A NYRB review. (HT: the enormously helpful Dave Lull)
To put it bluntly and polemically: Thomas Nagel is the real thing as philosophers go; Daniel Dennett is a sophist.
My Nagel category; my Dennett category.
Killer Quote:
I am reminded of the Marx Brothers line: “Who are you going to believe, me or your lying eyes?” Dennett asks us to turn our backs on what is glaringly obvious—that in consciousness we are immediately aware of real subjective experiences of color, flavor, sound, touch, etc. that cannot be fully described in neural terms even though they have a neural cause (or perhaps have neural as well as experiential aspects). And he asks us to do this because the reality of such phenomena is incompatible with the scientific materialism that in his view sets the outer bounds of reality. He is, in Aristotle’s words, “maintaining a thesis at all costs.”
That's right. When a line of reasoning issues in an absurdity such as the absurdity that consciousness and its deliverances are illusions, then what you have is a reductio ad absurdum of one or more of the premises with which the reasoning began. Dennett assumes physicalism and that everything can be explained in physical terms. This leads to absurdity. But Dennett, blinded by his own brilliance — don't forget, he counts himself one of the 'brights' — bites the bullet. He'd rather break his teeth than examine his assumptions.
Another thing struck me. Dennett makes much of Wilfrid Sellars' distinction between the manifest and scientific images. 'Image' is not quite the right word. An image is someone's image. But whose image is the scientific image? Who is its subject? It is arguably our image no less than the manifest image. Nagel quotes Dennett as saying of the manifest image: "It’s the world according to us." But the same, or something very similar, is true of the scientific image: it's the world in itself according to us. Talk of molecules, atoms, electrons, quarks, and strings is our talk just as much as talk of colors and plants and animals and haircuts and home runs.
The world of physics is the world as it is in itself according to us. Arguably, the 'according to us' gets the upper hand over the 'in itself' relativizing what comes within the former's scope much like Kant's transcendental prefix, Ich denke. Das 'ich denke' muss alle meine Vorstellungen begleiten koennen . . . . "The ''I think' must be able to accompany all my representations." (KdrV, B 131-2)
Arguably, the world of physics is a mind-involving construct arrived at by excluding the mental and abstracting away from the first-person point of view and the life world it reveals. I am alluding to an idealist approach to the problem of integrating the first- and third-person points of view. It has its own problems. But why is it inferior to a view like Dennett's which eliminates as illusory obvious data that are plainly not illusory?
Time was when absolute idealism was the default position in philosophy. Think back to the days of Bradley and Bosanquet. But reaction set in, times have changed, and the Zeitgeist is now against the privileging of Mind and for the apotheosis of Matter. (But again, matter as construed by us. Arguably, the scientific realist reifies theoretical constructs that we create and employ to make sense of experience.) Because idealism is out of vogue, the best and brightest are not drawn to its defense, and the brilliant few it attracts are too few to make much headway against the prevailing winds.
Now I'll tell you what I really think. The problem of integrating the first- and third-person points of view is genuine and perhaps the deepest of all philosophical problems. But it is insoluble by us. If it does have a solution, however, it certainly won't be anything like Dennett's.
Although Dennett's positive theory is worthless, his excesses are extremely useful in helping us see just how deep and many-sided and intractable the problem is.
The Primacy of the Intentional Revisited
Long-time reader writes,
I was going through some of your posts from earlier this month (Belief, Designation, and Substitution, January 10, 2017) and was interested in seeing your comment that "[l]inguistic reference is built upon, and nothing without, thinking reference, or intentionality.". . . I have to say that your above sentence was the first time I've heard anyone articulate what you have articulated in such a direct manner. It's something that certainly makes the most sense to me in terms of thinking about some of the broad discussion points in the field, but I'm surprised, actually, that no one I've come across has articulated this, and I'm curious whether that lacuna has to do with the analytic tradition's anti-metaphysical tendencies (of a more robust type of metaphysics, in any event): if one moves the object of analysis from questions about how language refers to how the mind refers, perhaps it gets one into hoary metaphysical waters that people back in the day would rather have left alone. Is this actually the case or am I missing something or is the whole thing simply too obvious for most people to bother mentioning?
It is actually an old debate within analytic philosophy. I would refer you to the 1957 Roderick Chisholm-Wilfrid Sellars correspondence although the debate antedates their discussion. Your note warrants the reposting of an old entry from six years ago. This is a redacted and expanded version.
Note to the Astute Opponent: Can you come up with a powerful counterargument to the primacy of the intentional? I'd like to test whether there is perhaps an aporia here.
The Primacy of the Intentional Over the Linguistic
Following Chisholm, et al. and as against Sellars, et al. I subscribe to the broadly logical primacy of the intentional over the linguistic.
But before we can discuss the primacy of the intentional, we must have some idea of (i) what intentionality is and (ii) what the problem of intentionality is. Very simply, (mental) intentionality is object-directedness, a feature of some (if not all) of our mental states. (The qualifier 'mental' leaves open the epistemic possibility of what George Molnar calls physical intentionality which transpires, if it does transpire, below the level of mind. I take no position on it at the moment. Dispositionality would count as physical intentionality.)
Suppose a neighbor asks me about Max Black, a stray cat of our mutual acquaintance, who we haven't seen in a few weeks. The asking occasions in me a thought of Max, with or without accompanying imagery. The problem of intentionality is to provide an adequate account of what it is for my thought of Max to be a thought of Max, and of nothing else. Simply put, what makes my thought of Max a thought of Max? How is object-directedness (intentionality, the objective reference of episodes of thinking) possible? How does it work? How does the mental act of thinking 'grab onto' a thing whose existence does not depend on my or anyone's thinking?
Why should there be a problem about this? Well, an episode of thinking is a datable event in my mental life. But a cat is not. First of all, no cat is an event. Second, no cat is a content of consciousness. It's an object of consciousness but not a content of consciousness. Cats ain't in the head or in the mind. Obviously, no cat is spatially inside my skull, or spatially inside my nonspatial mind, and it is only a little less obvious that no cat depends for its existence on my mind: it's nothing to Max, ontologically speaking, if me and my mind cease to exist. He needs for his existence my thinking of him as little as my thinking needs to be about him. We are external to each other. Cats are physical things out in the physical world. And yet my thinking of Max 'reaches' beyond my mind and targets — not some cat or other, but a particular cat. How is this possible? What must our ontology include for it to be possible?
To get the full flavor of the problem, please observe that my thinking of Max would be unaffected if Max were, unbeknownst to me, to pass out of existence while I was thinking of him. (He's out on the prowl and a hungry coyote kills him while I am thinking of him.) It would be the very same thought with the very same content and the very same directedness. But if Max were to cease to exist while a flea was biting him, then the relation of biting would cease to obtain. So if the obtaining of a relation requires the existence of all its relata, it follows that intentionality is not a relation between a thinker (or his thought) and an external object. But if intentionality is not a relation, then how are we to account for the fact that intentional states refer beyond themselves to objects that are (typically) transcendent of the mind?
How is it that the act of thinking and its content 'in the mind' hooks onto the thing 'in the world' and in such a way that true judgments can be made about the thing, judgments that articulate the nature and existence of thing as it is in itself apart from any (finite) thinking directed upon it?
Now it seems to me that any viable solution must respect the primacy of the intentional over the linguistic. This thesis consists of the following subtheses:
A. Words, phrases, clauses, sentences, paragraphs and the like, considered in their physical being as marks on paper or sounds in the air or carvings in stone (etc.) are entirely lacking in any intrinsic referential, representative, semantic, or intentional character. There is nothing in the nature of the mark 'red' that makes it mean red. After all, it doesn't mean red to a speaker of German. It doesn't mean anything to a speaker of German qua speaker of German. In German 'rot' means red while in English the same sign is in use but has a different meaning. Clearly, then, marks on paper, pixels on screen, etc. have no intrinsic sense or reference grounded in their very nature. It is a matter of conventional that they mean what they mean. And that brings minds into the picture.
B. So any sense or reference linguistic signs have must be derivative and relational as opposed to intrinsic: whatever intentionality they have they get from minds that are intrinsically intentional. Mind is the source of all intelligibility. Linguistic signs in and of themselves as mere marks and sounds (etc.) are unintelligible.
C. There can be mind without language, but no language without mind. Laird Addis puts it like this:
Conscious states can and do occur in beings with no language, and in us with no apparent connection to the fact that we are beings with language. Thus we may say that "mind explains language" in a logical or philosophical sense: that while it is perfectly intelligible to suppose the existence of beings who have no language but have much the same kinds of conscious states that we have, including introspections of other conscious states, it is unintelligible to suppose the existence of beings who are using language in all of its representative functions and who are also lacking in conscious states. The very notion of language as a representational system presupposes the notion of mind, but not vice versa. (Natural Signs: A Theory of Intentionality, Temple University Press, 1989, pp. 64-65)
These considerations strike me as decisive. Or are there counter-considerations that 'cancel them out'?
Intentionality, Potentiality, and Dispositionality: Some Points of Analogy
The influential Austrian philosopher Franz Brentano took intentionality to be the mark of the mental, the criterion whereby physical and mental phenomena are distinguished. For Brentano, (i) all mental phenomena are intentional, (ii) all intentional phenomena are mental, and (iii) no mental phenomenon is physical. (Franz Brentano, Psychologie vom empirischen Standpunkt (1874), Bk. II, Ch. 1.)
What is intentionality? ‘Intentionality’ is Brentano's term of art (borrowed from the Medievals) for that property of mental states whereby they are (non-derivatively) of, or about, or directed to, an object. Such states are intrinsically such that they 'take an accusative.' The state of perceiving, for example is necessarily object-directed. One cannot just perceive; if one perceives, then one perceives something. The idea is not merely that when one perceives one perceives something or other; the idea is that when one perceives, one perceives some specific object, the very object of that very act. The same goes for intending (in the narrow sense), believing, imagining, recollecting, wishing, willing, desiring, loving, hating, judging, knowing, etc. Such mental states refer beyond themselves to objects that may or may not exist, or may or may not be true in the case of propositional objects. Reference to an object is thus an intrinsic feature of mental states and not a feature they have in virtue of a relation to an existing object. This is why Brentano speaks of the "intentional in-existence of an object." It is also why Husserl can 'bracket' the existence of the object for phenomenological purposes. Intentionality is not a relation, strictly speaking, though it is relation-like. This is an important point that many contemporaries seem incapable of wrapping their heads around.
There are some interesting points of analogy between intentionality and potentiality. An intentional state exhibits
a. directedness to an object
b. an object that may or may nor exist
c. an object that may be, and typically is, indeterminate or incomplete.
For example, right now I am gazing out my study window at Superstition Mountain. The gazing is an intentional state: it is of or about something, a definite something. It takes an accusative, and does so necessarily. The accusative or intentional object in question presumably exists. But the intentional object is what it is whether or not it exists. The phenomenological description of object and act remains the same whether or not the object exists. Moreover, the object as presented in the act of gazing is incomplete: there are properties such that the intentional object neither has them nor their complements. Thus, to a quick glance, what is given in the intentional experience is 'a purplish mountain.' Just that. Now anything purple or purplish is colored, and anything colored is extended; but being colored and being extended are not properties of the intentional object. No doubt they are properties of the mountain itself in reality; but they are not properties of the precise intentional object of my gazing, which has all and only the properties it is seen to have. Furthermore, in reality, yonder mountain is either such that someone is climbing on it or not; but the intentional object of my momentary gazing is indeterminate with respect to the property of being climbed on by someone.
The potentiality inherent in a thing exhibits
a*. something analogous to intentional directedness: a potentiality is a potentiality for something, or to something. For example, a human embryo has the potentiality to develop, in the normal course of events, into a human neonate. But a human sperm cell lacks this potentiality. It has a different potentiality: it can combine with a human egg cell to form a zygote. A thing cannot just have a potentiality: every potentiality is a potentiality for something or to something. This something is not merely a something or other, but a definite something, analogously as in the case of intentional directedness.
b*. something analogous to the feature of an intentional experience whereby, from the occurrence of the intentional experience, one cannot infer the existence of its intentional object. Just as the intentional object may or may not exist without prejudice to its being an intentional object, a potentiality may or may not be realized. The embryo's potentiality to develop into a neonate may go unrealized — and this without prejudice to the potentiality's being something quite definite and quite real.
c*. something analogous to the incompleteness of intentional objects. To revert to a hackneyed example, an acorn has the potentiality to become an oak tree. But this is not to say that there is some perfectly determinate (definite) oak tree that an acorn has the potentiality to become, a 50 foot oak tree the diameter of whose trunk is two feet, etc.
The same points can be made about dispositions. If a piece of glass is fragile, then it is disposed to shatter if suitably struck. There cannot be a disposition that is not a disposition to do something, to shatter, or explode, or melt. Second, the reality of a disposition is independent of its manifestation: a fragile piece of glass is fragile whether or not it ever breaks. From the fact that x is disposed to F one cannot infer that x ever Fs. This parallels a feature of intentionality: from the fact that x is thinking about Fs one cannot infer that there exist Fs that x is thinking about. (If I am thinking about unicorns it does not follow that there exist unicorns I am thinking about; if I want a sloop it doesn't follow that there is a sloop I want; if Ernest is hunting lions it doesn't follow that there are any lions he is hunting.)
Third, although a manifested disposition is a fully determinate state of affairs, this complete determinateness is not present in the disposition qua disposition. The disposition to shatter if suitably struck is not the disposition to shatter into ten pieces if suitably struck, although it is of course the disposition to shatter into some number or other of pieces, the exact number being left indeterminate.
Now here is a tough question: are dispositionality and intentionality merely analogous, or can we take it a step further and say that utimately there is no difference between dispositionality and intentionality? If that case could be made, then Brentano would be shown to be wrong in his claim that intentionality is the mark of the mental. For if the three characteristics of intentionality mentioned above are found below the level of mind in the physical world, then it looks as if intentionality cannot be the mark of the mental. Or should we stay instead that, since intentionality is the mark of the mental, and intentionality is found in nature below the level of mind, that there is something mind-like about all of nature?
These are just (half-formulated) questions.
An Indiscernibility Argument for Dualism: Does it Beg the Question?
Here is a simple indiscernibility argument for substance dualism, presented simply:
1. If two things are identical, then whatever is true of the one is true of the other, and vice versa.
2. It is true of me that I can (logically) exist disembodied.
3. It is not true of any body that it can (logically) exist disembodied.
Therefore
4. I am not identical with any body.
The argument is valid in point of logical form, and (1), the Indiscernibility of Identicals, cannot be reasonably disputed. (3) too is irreproachable: it is surely impossible that a physical body exist without its body. My coffee cup can survive the loss of its handle, but not the loss of its very self. Destroy all its parts and you destroy it. So the soundness of the argument rides on the truth of (2). If (2) is true, there is no escaping the truth of (4). For an argument to be probative, however, it is not enough that it be sound; the premises must either be known to be true or at least reasonably believed to be true.
Do I have good reason to think that it is logically possible that I exist without a body? If so, then it is not necessarily the case that if you destroy all my physical parts, you destroy me. Well, the following is true and known to be true:
5. It is conceivable that I exist without a body.
By 'conceivable,' I don't just mean thinkable — round squares are thinkable — I mean thinkable without logical contradiction. And surely it is thinkable without logical contradiction that I exist without a body. Read your Descartes. I had a student once, a hopeless materialist, albeit otherwise alert and intelligent, who just could not appreciate the point. He kept repeating, "But if I shoot you dead, then you cease to exist!" What I found bizarre was that his religious upbringing hadn't even softened him up for the conceivability of post-mortem existence. It was as if he was so sunk into his bodily existence that the mere thought of not being identical to his body was unavailable to him. So I branded him a Cave-dweller and gave up on him. And then some years later, I gave up on teaching entirely. Why spend your life among unteachable troglodytes?
But now comes the hard part. How do we move validly from conceivability to possibility, from (5) to (2)? (2) affirms the (broadly) logical possibility of disembodied existence. But it is not clear why being able to conceive a state of affairs should guarantee its logical possibility. Note that it would serve no purpose to stipulate that logical possibility just is conceivability. That would have all the advantages of theft over honest toil. Broadly logical possibility is a species of real possibility, and one cannot just assume that what one can conceive without contradiction is possible in reality. (On the other hand, one can be certain that a concept harboring a contradiction cannot have anything answering to it in reality.)
Consider the FBI, the floating bar of iron. If my thought about the FBI is sufficiently abstract and indeterminate, then it will seem that there is no 'bar' to the FBI's logical possibility. If I think of the FBI as an object that has the phenomenal properties of iron (e.g., hardness) but also floats, then those properties are combinable in my thought without contradiction. There seems to be no logical contradiction in the thought of a hard metal that floats.
But if I know more about iron, including its specific gravity, and I import this information into my concept of iron, then the concept of the FBI will harbor a contradiction. The specific gravity of iron is 7850 kg/cu.m, which implies that it is 7.85 times more dense than water, which in turn implies that it will sink in water. For someone with this richer understanding, the FBI is a bar of iron that both floats and does not float — which is a contradiction.
What this example seems to show is that my failing to find a contradiction in my concept of X does not entail that X is logically possible; for it may be that my concept of X is insufficiently determinate, and that if I had a sufficiently determinate concept of X, then I would see from the concept alone that X is logically impossible. Now let's apply this to our problem. My disembodied existence is conceivable. But it might well be that my identity with my body is hidden from my powers of conception in a way similar to, but more radical than, the way the logical impossibility of floating iron is hidden from someone whose concept of iron is inadequate. It may be that my belief in the possibility of disembodied existence feeds on ignorance. How can I rule out this possibility?
If the only way to rule it out is by assuming the truth of (4), then the modal argument begs the question. So I conclude that the above argument is not rationally compelling or rationally coercive: a consumer of the argument can reasonably resist it. But the argument is rationally defensible and does provide a good though not compelling argument for dualism.
Two Senses of ‘Mystery’ and McGinn’s Mysterianism
Joel Hunter writes,
In the context of an exchange between a Catholic and a Protestant, I came across a quote of Gerard Manley Hopkins that reminded me of your posts on mysterianism.
You do not mean by mystery what a Catholic does. You mean an interesting uncertainty: the uncertainty ceasing, interest ceases also. This happens in some things; to you, in religion. But a Catholic by mystery means an incomprehensible certainty; without certainty, without formulation, there is no interest … The clearer the formulation, the greater the interest. At bottom, the source of interest is the same in both cases, in your mind and in ours; it is the unknown, the reserve of truth beyond what the mind reaches and still feels to be behind. But the interest a Catholic feels is, if I may say so, of a far finer kind than yours.
-Gerard Manley Hopkins, letter to Robert Bridges
This made me wonder whether mind-body mysterians like McGinn are really of the second type. If one holds that our inability to understand how a mental state could be a brain state is because of a natural limitation on our cognitive powers, like our inability to smell things that a dog can smell, then we might yet hold that this mystery is of type 1 – an "interesting uncertainty." One way that a materialist like McGinn might hold that consciousness is a type 1 mystery is to argue that, as with other of our physical powers, say vision, we could develop ways to augment our cognitive powers to understand thoughts we cannot (yet) think. The recent movie Lucy tangentially explores this.
Also, there's always the alien hypothesis, which seems to interest some very bright people, like Hawking. Intellectually, we may be bonobos compared to a more advanced race in the universe, whose cognitive powers far surpass our own, and for whom the solution to the mind-body problem is discussed and proven in the first year of their grade school. Of course, this is nothing more than an alien-of-the-gaps conjecture.
……………………………………….
BV responds:
In the Hopkins passage, which I find very obscure, two senses of 'mystery' are distinguished. They seem to me to be as follows.
Mystery-1: A proposition which, if true, is knowable, presently unknown, and interesting to know, but the interest of which evaporates upon being known. For example, the proposition Jimmy Hoffa's body was fed through a wood chipper is, if true, knowable, unknown, interesting to know but such that, if it came to be known, then the question of the final disposition of Hoffa's body would be settled and would no longer be interesting. A more timely example: The singer Prince's death came about as a result of his opioid addiction in tandem with a grueling work schedule. The aim of research is to banish mysteries in this first sense of 'mystery.'
Mystery-2: A proposition which, if true, cannot by us in this life be known to be true, and cannot even be known by us in this life to be logically-possibly true, i.e., free of logical contradiction, and is of the highest interest to us, but whose interest would in no way be diminished should we come to know it.
An example is the doctrine of the Trinity as understood by Roman Catholics (but not just by them). The Trinity is an exclusively revealed truth; hence it cannot be known by us by natural means. What's more, it cannot even be known by us to be free of logical contradiction and thus logically possible. Our finite intellects cannot see into its logical possibility let alone into its actual truth. We cannot understand how it is possible. But what is actual is possible whether or not we have the power to understand how it is possible. (Compare: motion is possible because actual, whether or not the Zenonian arguments to the contrary can be adequately answered.)
So from the fact that the Trinity appears to us in our present state as contradictory, and thus as logically impossible, it does not follow that it is not true. For it could be like this: given our unalterable ('hard-wired') cognitive architecture, certain revealed truths must appear to us as contradictory when the propositions which must so appear are not only in themselves not contradictory, but are also actually true!
One sort of mysterian is a person who holds that there are mysteries in the second sense. Is Colin McGinn a mysterian in this sense?
McGinn 'takes it on faith' that all mental activity is brain activity. He no more questions this than a believing Catholic questions the Trinity, the Incarnation, the Real Presence, etc. It just seems obvious to him and therefore a thesis that cannot be reasonably questioned. Of course mental activity is brain activity! What the hell else could it be? You think and feel with your brain, not your johnson, and certainly not with some 'spook in the skull' (my coinage) or "ghost in the machine." (Ryle)
But there are powerful arguments which I have rehearsed many times why qualia and object-directed mental states cannot be physical states. Confronted with these arguments, McGinn goes mysterian. He grants their force and then says something like this:
It is incomprehensible to us how consciousness could be a brain process. But it is a brain process. It is just that our unalterable cognitive architecture makes it impossible for us to see into this truth. It is true and therefore possibly true even though we cannot understand how it is true or even how it could be true due to our cognitive limitations.
As I read McGinn, these limitations are in our human case unalterable. And so I read McGinn as a mysterian in much the same sense that a theological mysterian is a mysterian. What is common to the doctor angelicus and the decidedly less than angelic McGinn is a commitment to the thesis that there are true, non-contradictory propositions that we humans by our very nature are not equipped to understand as either true or non-contradictory.
This leaves open the possibility for McGinn that there be extraterrestrials who are equipped to grasp mind-brain identity. And it leaves open for Aquinas the possibility that there be angelic intellects who are equipped to grasp God-Man identity (the Incarnation) and how Jesus Christ could ascend into heaven soul and body!
It would be very interesting to hear what James Anderson and Dale Tuggy have to say about this. They have gone far deeper into the mysteries of mysterianism than I have.

On the Separation and Attachment of Soul and Body
I was purchasing shotgun ammo at a gun store a while back. The proprietor brought out a box of double-aught buckshot shells which he recommended as having "the power to separate the soul from the body." The proprietor was a 'good old boy,' not someone with whom a wise man initiates a philosophical discussion. But his colorful phraseology got me thinking.
The words 'soul' and 'spirit' carry a cargo of both religious and substance-dualist connotations. And that is the way I will use them. The soul is that in us which thinks in the broad Cartesian sense of 'think.' it is the subject of consciousness and self-consciousness and moral sense (conscience). It is the thinker of our thoughts and the agent of our actions. It is the ultimate reference of the first person singular pronoun 'I' in its indexical use. But I must add that the soul is these things construed as capable of independent existence, as having not only an immaterial nature, but also an immaterial nature capable of existing on its own apart from these gross physical bodies with which we are all too familiar. So 'soul' is a theoretical term; it is not datanic or theory-neutral. 'Consciousness,' by contrast, is theory neutral. If you deny that there are souls, you will be forgiven, and you may even be right. If you deny that there is consciousness, however, then you are either a sophist, a lunatic, or an eliminativist, which is to say, a lunatic. Sophists and lunatics are not to be debated; they are to be 'shown the door.'
A substance, among other things, is an entity metaphysically capable of independent existence. The soul is a substance. It does not require some other thing in which to exist. (Nulla res indiget ad existendum.) So it is capable of independent existence. We encounter it as 'attached' to the body, but it can 'separate' from the body. The question is what these words mean in this context. The problem is to ascribe some coherent sense to them. What is the nature of this strange attachment?
1. Only physical things can be physically separated and physically attached. (The toenail from the toe; the stamp to the envelope; the spark plug from the cylinder; the yolk from the white, etc.) The soul is not a physical thing; ergo, souls cannot be physically separated from or attached to anything. So in this context we are not to take 'separation' and 'attachment' in any physical or material sense, whether gross or subtle. So don't think of ghosts or spooks floating out of gross bodies. Spook-stuff is still stuff, while what we are talking about now is not 'stuffy' at all.
2. It follows from this that every physical model is inadequate and just as, or more, misleading than helpful. The soul is not like the pilot in the ship, the man in his house, the oyster in the shell, the prisoner in his cell. These analogies may capture certain aspects of the soul-body relation, but they occlude others so that on balance they are of little use. But they are of some use. The morally sensitive, for example, experience a tension between their higher nature and their animal inclinations. There is more to the moral life than a struggle against the lusts of the flesh, but that is part of it. Thus the resonance of the Socratic image of the body as the prison-house of the soul.
3. The soul-body relation cannot literally be an instance of a physical relation, nor could it be an instance of a logical or mathematical or mereological or set-theoretical relation. We can lump these last four together under the rubric 'abstract relations.' Presumably the soul-body relation is sui generis. It's its own thing. Just as it would be absurd to say that entailment is an instance of a physical relation, it is absurd to suppose that soul-body is an instance of a physical or a logico-mathematical relation. The soul is neither a physical entity nor an abstract entity.
4. It seems to follow that if the the soul-body relation is sui generis, then there can be no model for it borrowed from some more familiar realm. The relation can only be understood in 'soulic,' or as I will say, spiritual terms. It can only be understood in its own terms. So let's consider mental or spiritual attachment. I am attached to my cat in the sense that, were he to die, I would grieve. Clearly, this is not a physical relation. Whether he is on my lap or far away, the attachment is the same. Spiritual attachment is consistent with physical separation. And spiritual non-attachment (spiritual separation) is consistent with physical proximity and indeed contact.
We allow ourselves to become attached to all sorts of things, people, and ideas, especially our own ideas. Attachments wax and wane. Many are foolish and even delusional. We become attached to what cannot last as if it will last forever. We become attached to what has no value. We have trouble apportioning our degree of attachment to the reality and value of attachment's object. As has been appreciated in many religions and wisdom traditions, much of our misery arises from desire and attachment to the objects of desire. For Pali Buddhism it is desire as such that is the problem; on more moderate views inordinate and misdirected desire. We are also capable of non-attachment or detachment, and this has been recommended in different ways and to different degrees by the religions and the wisdom traditions. There can be no doubt that non-attachment is a major component in wisdom.
5. None of this attaching and detaching would be possible without intentionality. The spiritual self, by virtue of its intentionality, flees itself and loses itself among the objects of its attachment. Chief among these is the mundane self: the body, the personality, their pasts, and the myriad of objects that one takes to be one's own. My car, my house, my wife, my children, my brilliant insights . . . . And now I come to my speculation. The soul attaches itself to this body here in a manner similar to the way it attaches itself to everything else to which it attaches itself. So attaching itself, my soul makes this body here my body. I come to 'inhabit' this body here, thereby making it my body, by my having chosen this body as the material locus of my subjectivity, as the vehicle of my trajectory through space-time. But when" Where? How? I chose this fall into time?
I am telling a Platonic story. I am penning yet another footnote to Plato. Who can believe it? Well, consider the alternatives! You are not your body and yet you are attached to it. What is your theory as to the nature of this attachment? I know what you will say. And I will have no trouble poking holes in it.
A Curious Extrapolation
The old man's libido on the wane, he thinks more clearly and more truly about sexual matters. And when the waning of all his physical forces and endowments reaches its term — will he then think best of all, or not at all?
The dove soars through the air and imagines it could soar higher and with less effort if there were no air to offer resistance. But the dove is mistaken. The dove on the wing does not understand the principle of the wing, Bernoulli's principle. Are we like the dove? The dove needs the air to fly. Do we need the body to think? Is the body necessary for thought? Pascal says that our whole dignity consist in thought. Is our dignity tied of necessity to the flesh ?
Or are we like the rocket whose propulsion has nothing to do with wings, the rocket the principle of whose propulsion is Newton's Third Law of Motion: To every action there is an equal but opposite reaction?
A curious extrapolation and a strange analogy.
God and Mind: Indiscernibility Arguments
Are the Christian and Muslim Gods the same? Why not settle this in short order with a nice, crisp, Indiscernibility argument? To wit,
a. If x = y, then x, y share all intrinsic properties. (A version of the Indiscernibility of Identicals)
b. The God of the Christians and that of the Muslims do not share all intrinsic properties: the former is triune while the latter is not.
Therefore
c. The God of the Christians is not identical to that of the Muslims.
Not so fast!
With no breach of formal-logical propriety one could just as easily run the argument in reverse, arguing from the negation of (c) to the negation of (b). They are the same God, so they do share all intrinsic properties!
But then what about triunity? One could claim that triunity is not an intrinsic property. A Muslim might claim that triunity is a relational property, a property that involves a relation to the false beliefs of Christians. In other words, triunity is the relational property of being believed falsely by Christians to be a Trinity.
Clearly, a relational property of this sort cannot be used to show numerical diversity. Otherwise, one could 'show' that the morning and evening 'stars' are not the same because Shlomo of Brooklyn believes of one that it is a planet but of the other than it is a star.
Now consider a 'mind' argument.
a. If x = y, then x, y share all intrinsic properties. (A version of the Indiscernibility of Identicals)
b*. This occurrent thinking of Venus and its associated brain state do not share all intrinsic properties: my mental state is intentional (object-directed) whereas my brain state is not.
Therefore
c*. This occurrent thinking of Venus is not identical to its associated brain state.
Not so fast! A resolute token-token mind-brain identity theorist will run the argument in reverse, arguing from the negation of (c*) to the negation of (b*).
But then what about intentionality? The materialist could claim that intentionality is not an intrinsic property, but a relational one. Taking a page from Daniel Dennett, he might argue that intentionality is a matter of ascription: nothing is intrinsically intentional. We ascribe intentionality to what, in itself, is non-intentional. So in reality all there is is the brain state. The intentionality is our addition.
Now Dennett's ascriptivist theory of intentionality strikes me as absurd: it is either viciously infinitely regressive, or else viciously circular. But maybe I'm wrong. Maybe the infinite regress is benign. Can I show that it is not without begging the question?
Question for the distinguished MavPhil commentariat: Are there good grounds here for solubility-skepticism when it comes to philosophical problems?
“And the Word Was Made Flesh and Dwelt Among Us” (John 1:14)
Let us meditate this Christmas morning on the sheer audacity of the idea that God would not only enter this world of time and misery, but come into it in the most humble manner possible, inter faeces et urinam nascimur, born between feces and urine, entering between the legs of a poor girl in a stable. Just like one of us, a slob like one of us. The notion is so mind-boggling that one is tempted to credit it for this very reason, for its affront to Reason, and to the natural man, accepting it because it is absurd, or else dismissing it as the height of absurdity. A third possibility is to accept it despite its being absurd, and a fourth is to argue that rational sense can be made of it. The conflict of these approaches, and of the positions within each, only serves to underscore the mind-boggling quality of the notion, a notion that to the eye and mind of faith is FACT.
The Most High freely lowers himself, accepting the indigence and misery of material existence, including a short temporal career that ends with the ultimate worldly failure: execution by the political authorities. And not a civilized Athenian execution by hemlock as was the fate of that other great teacher of humanity, but execution by the worst method the brutal Romans could devise, crucifixion.
In the Incarnation the Word nailed itself to the flesh in anticipation of later being nailed to the wood of the cross to suffer the ultimate fate of everything material and composite: dissolution. Christ dies like each of us will die, utterly, alone, abandoned. But then the mystery: He rises again. Is this the central conundrum of Christianity? He rises, but not as a pure spirit. He rises body and soul.
God is the Word ("In the beginning was the Word, and the Word was with God, and the Word WAS God"); the Word becomes flesh; the flesh nailed to wood becomes dead matter and nothing Wordly or Verbal or Logical or Spiritual or Sense Bearing, and so next-to-nothing; but then the next-to-nothing rises and ascends body and soul to the Father by the power of the Father. Christ rises bodily and ascends bodily. A strange idea: bodily ascension out of the entire spatio-temporal-bodily matrix! He ascends to the Father who is pure spirit. So, in ascending, Christ brings matter, albeit a transformed or transfigured matter, into the spiritual realm which must therefore be amenable to such materialization. It must permit it, be patient of it. The divine spiritual milieu cannot be essentially impervious to material penetration.
Before the creation and before the Incarnation of the Creator into the created order divine spirit had the power to manifest itself materially, and in the Incarnation the power not only to manifest itself materially but to become material. The divine Word becomes flesh; the Word does not merely manifest itself in a fleshly vehicle. It becomes that vehicle and comes to suffer the fate of all such vehicles, dissolution. The divine spirit was always already apt for materialization: it bore this possibility within it from the beginning. It was always already in some way disposed toward materialization. On the other hand, matter was always already apt for spiritualization.
We humans know from experience that we can in some measure spiritualize ourselves and indeed freely and by our own power. We know ourselves to be spiritual beings while also knowing ourselves to be animals, animated matter, necessarily dependent on inanimate matter including air, water, dead plants and dead meat. (When an animal eats another animal alive, the first is after the matter of the second, not after its being animated.)
Whether or not we exercise our severely limited power of self-spiritualization, we are spiritual animals whether we like it or not and whether we know it or not: we think. Each one of us is a hunk of thinking meat. We are meaning meat. How is this possible? The matter of physics cannot think. But we are thinking matter. This is the mystery of the entanglement of spirit and matter in us. We live it and we experience it.
We could call it the 'The Little Incarnation.' Mind is incarnated, enfleshed, in us. The Little Word, the Little Logos, has always already been incarnated is us, separating us as by an abyss from the rest of the animals. Here, in us, we have an ANALOGY to the Incarnation proper. In the latter, the Second Person of the Trinity does not take on a human body merely, but an individual human nature body and soul. So I speak of an analogy. Incarnation in the case of Christ is not a mere enfleshment or embodiment. The Little Incarnation in us is the apparently necessary enfleshment of our spiritual acts in animal flesh.
The mystery of the entanglement of spirit and matter in us reflects the mystery of the entanglement of spirit and matter in God. Divine spirit is pregnant with matter, and accepting of the risen matter of Christ, but matter is also pregnant with divine spirit. Mary is the mother of God. A material being gives birth to God. This is how the Word, who is God, is made flesh to dwell among us for our salvation from meaninglessness and abandonment to a material world that is merely material.
Matter in Mary is mater Dei. Matter in Mary is mother and matrix of the birth of God.
