The Self as Center of Narrative Gravity?

According to the The New York Times, Daniel Dennett has a new book coming out entitled Intuition Pumps and Other Tools for Thinking. Here are a couple of tidbits from the NYT piece:

The self? Simply a “center of narrative gravity,” a convenient fiction that allows us to integrate various neuronal data streams.

The elusive subjective conscious experience — the redness of red, the painfulness of pain — that philosophers call qualia? Sheer illusion.

This sure sounds like the sort of sophistry Dennett is known for. Selves are fictions that allow us — selves — to integrate data streams. I hope I will be forgiven for finding that unintelligible.

Now which is more likely to be true, that qualia are "sheer illusion" or that Dennett is a sophist?

You know my answer. Here are a couple of anti-Dennett posts:

Matter Thinks?

I dedicate this post to Victor Reppert who thinks along similar lines, and shares my love of the oldies.

…………

If matter could think, then matter would not be matter as currently understood.

Can abstracta think? Sets count as abstracta. Can a set think? Could the set of primes contemplate itself and think the thought, 'I am a set, and each of my members is a prime number'? Given what we know sets to be from set theory, sets cannot think. It is the same with matter. Given what we know or believe matter to be from current physics, matter cannot think. To think is to think about something, and it is this aboutness or intentionality that proves embarrassing for materialism. I have expatiated on this over many, many posts and I can't repeat myself here. (Here is a characteristic post.)

But couldn't matter have occult powers, powers presently hidden from our best physics, including the power to think? Well, could sets have occult powers that a more penetrating set theory would lay bare? Should we pin our hopes on future set theory? Obviously not. Why not? Because it makes no sense to think of sets as subjects of intentional states. We know a priori that the set of primes cannot lust after the set of evens. It is impossible in a very strong sense: it is broadly logically impossible.

Of course, there is a big difference between sets and brains. We know enough about sets to know a priori that sets cannot think. But perhaps we don't yet know enough about the human brain. So I don't dogmatically claim that matter could not have occult or hidden powers. Maybe the meat between my ears does have the power to think. But then that meat is not matter in any sense we currently understand. And that is my point. You can posit occult powers if you like, and pin your hopes on a future science that will lay them bare; but then you are going well beyond the empirical evidence and engaging in high-flying speculations that ought to seem unseemly to hard-headed empiricistic and scientistic types.

Such types are known to complain about spook stuff and ghosts-in-machines. But to impute occult powers, powers beyond our ken, to brain matter does not seem to be much of an improvement. For that is a sort of dualism too. There are the properties and powers we know about, and the properties and powers we know nothing about but posit to avoid the absurdities of identity materialism and eliminativism. There is also the dualism of imagining that matter when organized into human brains is toto caelo different from ordinary hunks of matter. There is also a dualism within the brain as between those parts of it that are presumably thinking and feeling and those other parts that perform more mudane functions. Why are some brain states mental and others not? Think about it. (I have a detailed post on this but I don't have time to find it.)

The materialist operates with a conception of matter tied to current physics. On that conception of matter, it is simply unintelligible to to say that brains feel or think. If he nonetheless ascribes mental powers to matter, then he abandons materialism for something closer to panpsychism. I seem to recall Reppert making this point recently.

It is worth noting that the reverent gushing of the neuro-scientistic types over the incredible complexity (pound the lectern!) 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 can trigger a metabasis eis allo genos, a shift into another genus. 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, labelling the problem without solving it. Do you materialists believe in miracle meat or mystery meat? Do you believe in magic?

Are Propositions Counterexamples to Brentano’s Thesis?

Franz Brentano, for whom intentionality is the mark of the mental, is committed to the thesis that all instances of (intrinsic) intentionality are instances of mentality. Propositions and dispositions are apparent counterexamples. For they are nonmental yet intrinsically object-directed. Whether they are also real counterexamples is something we should discuss. This post discusses (Fregean) propositions. Later, dispositions — if I am so disposed.

On one approach, propositions are abstract objects. Since abstracta are categorially barred from being mental, it is clear that if intrinsic intentionality is ascribed to abstract propositions, then the thesis that all instances of intentionality are instances of mentality must be rejected. For specificity, we consider Frege's theory of propositions. He called them Gedanken, thoughts, which is a strangely pyschologistic terminological choice for so anti-psychologistic a logician, but so be it.

A proposition is the sense (Sinn) of a certain sort of sentence in the indicative mood, namely, an indicative sentence from which all indexical elements, if any, such as the tenses of verbs, have been extruded. Consider the following sentence-tokens each of which features a tenseless copula:

1. The sea is blue
2. The sea is blue
3. Die See ist blau
4. Deniz mavidir.

(Since Turkish is an agglutinative language, the copula in the Turkish sentence is the suffix 'dir.')

The (1)-(4) array depicts four sentence-tokens of three sentence-types expressing exactly one proposition. Intuitively, the four sentences say the same thing, or to be precise, can be used by people to say the same thing. That same thing is the proposition they express, or to be precise, that people express by uttering them. The proposition is one to their many. And unlike the sentence-tokens, it is nonphysical, which has the epistemological consequence that it, unlike the sentence-tokens, cannot be seen with the eyes. It is 'seen' (understood) with the mind. Frege is a sort of latter-day Platonist.

So one reason to introduce propositions is to account for the fact that the same meaning-content can be expressed by different people using different sentences of different languages. Another reason to posit propositions is to have a stable entity to serve as vehicle of the truth-values. The idea is that it is the proposition that is primarily either true or false. Given that a proposition is true, then any sentence expressing it is derivatively true.

There is quite a lot to be said for the view that a sentence-token cannot be a primary truth-bearer. For how could a string of marks on paper, or pixels on a screen, be either true or false? Nothing can be either true or false unless it has meaning, but how could mere physical marks (intrinsically) mean anything? Merely physical marks, as such, are meaningless. You can't get blood from a stone, or meaning from meat, no matter how hard you squeeze, and no matter how wondrously organized the meat.

Fregean propositions are especially useful when it comes to the necessary truths expressed by such sentences as '7 is prime.' A necessary truth is true in all possible worlds, including those worlds in which there is nothing physical and so no means of physically expressing truths. If truth is taken to be a property of physical items or any contingent item, then it might be difficult to account for the existence of necessary truths. The Fregean can handle this problem by saying that propositions, as abstract objects, exist in all possible worlds, and that true ones have the property of being true in all possible worlds. The Fregean can also explain how there can be necessary truths in worlds in which there is nothing physical and nothing mental either.

Propositions also function as the accusatives of the so-called 'propositional attitudes' such as belief. To believe is to believe something. One way to construe this is de dicto: to believe is to stand in a relation to a proposition. Thus if I believe that the river Charles is polluted, then the intentional object of the belief is the proposition expressed by 'The river Charles is polluted.' (Of course, there is also a de re way of construing the belief in question: To believe that the Charles is polluted is to believe, of the river Charles, that is is polluted.)

Well, suppose one endorses a theory of propositions such as the one just sketched. You have these necessarily existent Platonic entities called propositions some of which are true and some of which are false. My believing that p is an intentional state directed upon p; but is it not also the case that p is directed upon the world, or upon a truth-making state of affairs in the world in the case in which p is true?

But now it looks as if we have two sorts of intentionality, call them noetic and noematic, to borrow some terminology from Husserl. Noetic intentionality connects a mental state (in Frege's Second Reich) to a proposition (in Frege's Third Reich), and noematic intentionality connects, or purports to connect, a proposition to an object in Frege's First Reich. Frege wouldn't think of this object as a state of affairs or concrete fact, of course, but we might. (The peculiarities of Frege's actual views don't matter for this discussion.)

The problem for Brentano's thesis above is that propositions — which are abstract objects — seem to display intrinsic aboutness: they are about the concrete world or states of affairs in the world. Thus the proposition expressed by 'The Charles is polluted' is intrinsically about either the river Charles or else about the state of affairs, The Charles River's being polluted. Intrinsically, because the proposition's being about what it is about does not depend on anyone's interpretation.

If this is right, then some instances of intentionality are not only not conscious but not possibly conscious. Does this refute Brentano's thesis? Brentano himself denied that there were such irrealia as propositions and so he would not take propositions as posing any threat to his thesis. But if there are (Fregean) propositions, then I think they would count as counterexamples to Brentano's thesis about intentionality.

Is there a way to uphold Brentano's thesis that only the mental is intrinsically intentional? Yes, if there is a way to identify propositions with thoughts or rather content-laden thinkings. My thinking that 7 is prime is intrinsically intentional. Unfortunately, my thinking is contingent whereas the content of my thinking is necessarily true and hence necessarily existent. To identify propositions with content-laden thinkings one would have to take the thinkings to inhere in a necessarily existent mind such as the mind of God.

So I end on an aporetic note. Intentionality cannot be the mark of the mental if there are Fregean propositions. But given that there are necessary truths and that truth-bearers cannot be physical items, then only way to avoid Fregean propositions is by identifying propositions with divine thoughts, in which case they are Gedanken after all.

Thinking Meat?

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 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 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 functioning brain? The fact that we cannot understand how the brain could be a semantic engine 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 can 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, labelling 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.

Galen Strawson versus Nicholas Humphrey on Consciousness

A couple of days ago I had Nicholas Humphrey in my sights. Or, to revert to the metaphor of that post, I took a shovel to his bull. I am happy to see that Galen Strawson agrees that it is just nonsense to speak of consciousness as an illusion. Strawson's trenchant review of Humphrey's Soul Dust: The Magic of Consciousness is here. Unfortunately, I cannot see that Strawson has shed much light either, at least judging from the sketch of his position presented in the just-mentioned review:

There is no mystery of consciousness as standardly presented, although book after book tells us that there is, including, now, Nick Humphrey's Soul Dust: The Magic of Consciousness. We know exactly what consciousness is; we know it in seeing, tasting, touching, smelling, hearing, in hunger, fever, nausea, joy, boredom, the shower, childbirth, walking down the road. If someone denies this or demands a definition of consciousness, there are two very good responses. The first is Louis Armstrong's, when he was asked what jazz is: "If you got to ask, you ain't never goin' to know." The second is gentler: "You know what it is from your own case." You know what consciousness is in general, you know the intrinsic nature of consciousness, just in being conscious at all.

"Yes, yes," say the proponents of magic, "but there's still a mystery: how can all this vivid conscious experience be physical, merely and wholly physical?" (I'm assuming, with them, that we're wholly physical beings.) This, though, is the 400-year-old mistake. In speaking of the "magical mystery show", Humphrey and many others make a colossal and crucial assumption: the assumption that we know something about the intrinsic nature of matter that gives us reason to think that it's surprising that it involves consciousness. We don't. Nor is this news. Locke knew it in 1689, as did Hume in 1739. Philosopher-chemist Joseph Priestley was extremely clear about it in the 1770s. So were Eddington, Russell and Whitehead in the 1920s.

One thing we do know about matter is that when you put some very common-or-garden elements (carbon, hydrogen, oxygen, sodium, potassium, etc) together in the way in which they're put together in brains, you get consciousness like ours – a wholly physical phenomenon. (It's happening to you right now.) And this means that we do, after all, know something about the intrinsic nature of matter, over and above everything we know in knowing the equations of physics. Why? Because we know the intrinsic nature of consciousness and consciousness is a form of matter.

The main point of Strawson's first paragraph is surely correct: we know what consciousness is in the most direct and and unmistakable way possible: we experience it, we live through it, we are it. We know it from our own case, immediately, and we know it better than we know anything else. If Dennett doesn't know what a sensory quale is, then perhaps the cure is to administer a sharp kick to his groin. Feel that, Dan? That's a quale. (I am assuming, of course, that Dennett is not a 'zombie' in the technical sense in which that term is used in philosophy of mind discussions. But I can't prove he isn't. Perhaps that is the problem. If he were a zombie, then maybe all his verbal behavior would be understandable.)

In the second paragraph Strawson rejects an assumption and he makes one himself. He rejects the assumption that we know enough about the intrinsic nature of matter to know that a material being cannot think. The assumption he makes is that we are wholly physical beings. So far I understand him. It could be that (it is epistemically possible that) this stuff inside my skull is the thinker of my thoughts. This is epistemically possible because matter could have hidden powers that we have yet to fathom. On our current understanding of matter it makes no bloody sense to maintain that matter thinks; but that may merely reflect our ignorance of the intrinsic nature of matter. So I cannot quickly dismiss the notion that matter thinks in the way I can quickly dismiss the preternaturally boneheaded notion that consciousness is an illusion.

I agree with Strawson's first paragraph; I understand the second; but I am flabbergasted by the third. For now our man waxes dogmatic and postures as if he KNOWS that consciousness is a wholly physical phenomenon. How does he know it? Obviously, he doesn't know it. It is a mere conjecture, an intelligible conjecture, and perhaps even a reasonable one. After all it might be (it is epistemically possible that) the matter of our brains has occult powers that physics has yet to lay bare, powers that enable it to think and feel. I cannot exclude this epistemic possibility, any more than Strawson can exclude the possibility that thinkers are spiritual substances. But to conjecture that things might be thus and so is not to KNOW that they are thus and so. All we can claim to KNOW is what Strawson asseverates in his first paragraph.

Here is Strawson's argument in a nutshell:

1. We know the intrinsic nature of consciousness from our own case.

2. We know that consciousness is a form of matter.

Ergo

3. There is nothing mysterious about consciousness or about how matter gives rise to consciousness; nor is there any question whether consciousness is wholly physical; the only mystery concerns the intrinsic nature of matter.

The problem with this argument is premise (2). It is pure bluster: a wholly gratuitous assumption, a mere dogma of naturalism. I can neutralize the argument with this counterargument:

4. If (1) & (2), then brain matter has occult powers.

5. We have no good reason to assume — it is wholly gratuitous to assume — that brain matter has occult powers.

Therefore

6. We have no good reason to assume that both (1) and (2) are true.

7. We know that (1) is true.

Therefore

8. We have good reason to believe that (2) is false.

Bull Meets Shovel: Could Consciousness Be A Conjuring Trick?

The following statement by Nicholas Humphrey (Psychology, London School of Economics) is one among many answers to the question: What do you believe is true though you cannot prove it?

I believe that human consciousness is a conjuring trick, designed to fool us into thinking we are in the presence of an inexplicable mystery. Who is the conjuror and why is s/he doing it? The conjuror is natural selection, and the purpose has been to bolster human self-confidence and self-importance—so as to increase the value we each place on our own and others' lives.

If this is right, it provides a simple explanation for why we, as scientists or laymen, find the "hard problem" of consciousness just so hard. Nature has meant it to be hard. Indeed "mysterian" philosophers—from Colin McGinn to the Pope—who bow down before the apparent miracle and declare that it's impossible in principle to understand how consciousness could arise in a material brain, are responding exactly as Nature hoped they would, with shock and awe.

Can I prove it? It's difficult to prove any adaptationist account of why humans experience things the way they do. But here there is an added catch. The Catch-22 is that, just to the extent that Nature has succeeded in putting consciousness beyond the reach of rational explanation, she must have undermined the very possibility of showing that this is what she's done.

But nothing's perfect. There may be a loophole. While it may seem—and even be—impossible for us to explain how a brain process could have the quality of consciousness, it may not be at all impossible to explain how a brain process could (be designed to) give rise to the impression of having this quality. (Consider: we could never explain why 2 + 2 = 5, but we might relatively easily be able to explain why someone should be under the illusion that 2 + 2 = 5).

Do I want to prove it? That's a difficult one. If the belief that consciousness is a mystery is a source of human hope, there may be a real danger that exposing the trick could send us all to hell.

Humphrey mentions the 'hard problem.' David Chalmers formulates the 'hard problem' as follows: "Why is all this processing accompanied by an experienced inner life?" (The Conscious Mind, Oxford 1996, p. xii.) Essentially, the 'hard problem' is the qualia problem. To explain it in detail would require a separate post. Humphrey offers us an explanation of why the 'hard problem' is hard. It is hard because nature or natural selection — Humphrey uses these terms interchangeably above — meant it to be hard. Her purpose is to "fool us into thinking we are in the presence of an inexplicable mystery." She wants to fool us in order to "bolster human self-confidence and self-importance." How thoughtful of her. Of course, to say that she is fooling us implies that consciousness is not mysterious but just another natural occurrence.

Not only does Nature fool us into thinking that consciousness is mysterious, when it is not, she also makes it impossible for us to see that this is what she has done. But there may be a loophole: it may be possible to "explain how a brain process could be (designed to) give rise to the impression of having this quality," i.e., the quality of consciousness. By 'impression,' Humphrey means illusion as is clear from his arithmetical example. So what he is suggesting is that it may be possible to explain how brain processes could give rise to the illusion that there is consciousness, the illusion that brain processes have the quality of consciousness.

But this 'possibility' is a complete absurdity, a complete impossibility. For it is self-evident that illusions presuppose consciousness: an illusion cannot exist without consciousness. The 'cannot' expresses a very strong impossibility, broadly logical impossibility. The Germans have a nice proverb, Soviel Schein, so viel Sein. "So much seeming, so much being." The point being that you can't have Schein without Sein, seeming without being. It can't be seeming 'all the way down.'

The water espied by a parched hiker might be an illusion (a mirage), but it is impossible that consciousness be an illusion. For wherever there is illusion there is consciousness, and indeed the reality of consciousness, not the illusion of consciousness. If you said that the illusion of consciousness is an illusion for a consciousness that is itself an illusion you would be embarked upon a regress that was both infinite and vicious. Just as the world cannot be turtles all the way down, consciousness cannot be illusion all the way down.

In the case of the mirage one can and must distinguish between the seeming and the being. The being (reality) of the mirage consists of heat waves rising from the desert floor, whereas its seeming (appearance) involves a relation to a conscious being who mis-takes the heat waves for water. But conscious states, as Searle and I have been arguing ad nauseam lo these many years, are such that seeming and being, appearance and reality, coincide. For conscious qualia, esse est percipi. Consciousness cannot be an illusion since no sort of wedge can be driven between its appearance and its reality.

A French philosopher might say that consciousness 'recuperates itself' from every attempt to reduce it to the status of an illusion. The French philosopher would be right — if interpreted in my more sober
Anglospheric terms.

It is also important to note how Humphrey freely helps himself to intentional and teleological language, all the while personifying Nature with a capital 'N.' Nature meant the hard problem to be hard, she had a purpose in fooling us. She fooled us. Etc. This is a typical mistake that many naturalists make. They presuppose the validity of the very categories (intentionality, etc.) that their naturalistic schemes would eliminate. How could they fail to presuppose them? After all, naturalists think about consciousness and other things, and they have a purpose in promoting their (absurd) theories.

There is no problem with using teleological talk as a sort of shorthand, but eventually it has to be cashed out: it has to be translated into 'mechanistic' talk. Eliminativists owe us a translation manual. In the absence of a translation manual, they can be charged with presupposing what they are trying to account for, and what is worse, ascribing meanings and purposes to something that could not possibly have them, namely, Natural Selection personified. What is the point of getting rid of God if you end up importing purposes into Natural Selection personified, or what is worse, into 'selfish' genes?

So Humphrey's statement is bullshit in the sense of being radically incoherent. It is pseudo-theory in the worst sense. One of the tasks of philosophers is to expose such pseudo-theory which, hiding behind scientific jargon (e.g, 'natural selection'), pretends to be scientific when it is only confused.

A central task of philosophy is the exposure of bad philosophy.

Galen Strawson and Nicholas Humphrey on Consciousness

Alex Kealy (Institute of Art and Ideas, London) writes:

I'm getting in contact from the Institute of Art and Ideas in Britain as we've just released a video I thought you might be interested in. Called "The Mind's Eye", the video is of a discussion that took place at our philosophy festival HowTheLightGetsIn last year. The panel includes philosopher of mind Galen Strawson and evolutionary psychologist Nicholas Humphrey, and the debate focusses on the nature of the consciousness, whether the term soul is useful and if — as Strawson alleges — consciousness is merely an unproblematic result of certain combinations of physical elements. I know that in the past you've blogged on consciousness / qualia and so I thought you might perhaps be interested in posting a link to the video on your blog (it can be found at http://www.iai.tv/video/the-mind-s-eye ), if you find find it of interest and think it might appeal to your readers.

I don't have time now to watch the entire video, but from the opening frames it looks promising.

Ignorabimus

We are ignorant about ultimates and we will remain ignorant in this life. Perhaps on the Far Side we will learn what we cannot learn here. But whether there is survival of bodily death, and whether it will improve our epistemic position, are again things about which — we will remain ignorant in this life.

It is admittedly strange to suppose that death is the portal to knowledge. But is it stranger than supposing that a being capable of knowledge simply vanishes with the breakdown of his body?

The incapacity of materialists to appreciate the second strangeness I attribute to their invincible body-identification.

On Light

Today I preach on a text from Joseph Joubert:

Light. It is a fire that does not burn. (Notebooks, 21)

Just as the eyes are the most spiritual of the bodily organs, light is the most spiritual of physical phenomena. And there is no light like the lambent light of the desert. The low humidity, the sparseness of vegetation that even in its arboreal forms hugs the ground, the long, long vistas that draw the eye out to shimmering buttes and mesas — all of these contribute to the illusion that the light is alive. This light does not consume, like fire, but allows things to appear. It licks, like flames, but does not incinerate. ('Lambent' from Latin lambere, to lick.)

Light as phenomenon, as appearance, is not something merely physical. It is as much mind as matter. Without its appearance to mind it would not be what it, phenomenologically, is. But the light that allows rocks and coyotes to appear, itself appears. This seen light is seen within a clearing, eine Lichtung, which is light in a transcendental sense. But this transcendental light in whose light both illuminated objects and physical light appear, points back to the onto-theological Source of this transcendental light.

Augustine claims to have glimpsed this eternal Source Light upon entering into his "inmost being." Entering there, he saw with his soul's eye, "above that same eye of my soul, above my mind, an unchangeable light." He continues:

It was not this common light, plain to all flesh, nor a greater light of the same kind
. . . Not such was that light, but different, far different from all other lights. Nor was it above my mind, as oil is above water, or sky above earth. It was above my mind, because it made me, and I was beneath it, because I was made by it. He who knows the truth, knows that light, and he who knows it knows eternity. (Confessions, Book VII, Chapter 10)

'Light,' then, has several senses. There is the light of physics, which is but a theoretical posit. There is physical light as we see it, whether in the form of illuminated things such as yonder mesa, or sources of illumination such as the sun, or the lambent space between them. There is the transcendental light of mind without which nothing at all would appear. There is, above this transcendental light, its Source.

One could characterize a materialist as one who is blind to the light, except in the first of the four senses lately mentioned.

Eben Alexander: “We Are Conscious in Spite of Our Brains”

I am at the moment listening to Dennis Prager interview Dr. Eben Alexander. Prager asked him whether he now maintains, after his paranormal experiences, that consciousness is independent of the brain. Alexander made a striking reply: "We are conscious in spite of our brains." And then he made some remarks to the effect that the brain is a "reducing filter" or something like that.

That is to say much more than that consciousness can exist independently of the brain. For the latter would be true if consciousness existed in an attenuated form after the dissolution of the body and brain. Alexander is saying that embodiment severely limits our awareness.

Well, why couldn't that be true? Why is it less plausible than a form of materialism that views consciousness as somehow dependent on brain functioning and impossible without it?

Let us assume you are not a dogmatist: you don't uncritically adhere to the unprovable materialist framework assumption according to which consciousness just has to be brain-based. And let us assume that you don't have a quasi-religious faith that future science has wonderful revelations in store that will vindicate materialism/physicalism once and for all. By the way, I have always found it passing strange that people would "pin their hopes on future science." You mean to tell me that you hope you can be shown to be nothing more than a complex physical system slated for utter extinction!? That's what you hope for? It may in the end be true, but I for one cannot relate to the mentality of someone who would hope for such a thing. "I hope I am just a bag of chemicals to be punctured in a few years. Wouldn't it be awful if I had an higher destiny and that life actually had a meaning?"

But I digress. Let's assume you are not a dogmatist and not a quasi-religious believer in future science. Let's assume you are an open-minded inquirer like me. You are skeptical in the best sense: inquisitive but critical. Then I put the question to you: Can you show that the Alexander claim is less plausible that the materialist one?

I don't believe that there can be talk of proof either way, assuming you use 'proof' strictly. You have to decide what you will believe and how you will live. In the shadowlands of this life there is light enough and darkness enough to lend support to either answer, that of the mortalist and that of his opposite number.

So I advance to the consideration that for me clinches the matter. Bring the theoretical question back down to your Existenz. How will you live, starting right now and for the rest of your days? Will you live as if you will be utterly extinguished in a few years or will you live as if what you do and leave undone right now matters, really matters? Will you live as if life is serious, or will you live as if it is some sort of cosmic joke? Will you live as if something is at stake in this life, however dimly descried, or will you live as if nothing is ultimately at stake? It is your life. You decide.

Now suppose that when Drs. Mary Neal and Eben Alexander die the body's death, they become nothing. Suppose that their phenomenologically vivid paranormal experiences were revelatory of nothing real, that their experiences were just the imaginings of malfunctioning brains at the outer limits of biological life. What will they have lost by believing as they did?

Nothing! Nothing at all. You could of course say that they were wrong and were living in illusion. But no one will ever know one way or the other. And if the body's death is the last word then nothing ultimately matters, and so it can't matter that they were wrong if turns out that they were.

If they were right, however, then the moral transformation that their taking seriously of their experiences has wrought in them can be expected to redound to their benefit when they pass from this sphere.

Plantinga Reviews Nagel

I am beginning to feel a little sorry for Thomas Nagel. It looks as if the only favorable mainstream reviews he will receive for his efforts in Mind and Cosmos will be from theists. What excites the theists' approbation, of course, are not Nagel's positive panpsychist and natural-teleological suggestions, which remain within the ambit of naturalism, but his assault on materialist naturalism. As Alvin Plantinga writes in his excellent review, Why Darwinist Materialism is Wrong, "I applaud his formidable attack on materialist naturalism; I am dubious about panpsychism and natural teleology." And so Nagel's predicament, at least among reviewers in the philosophical mainstream, seems to be as follows. The naturalists will reject his book utterly, both in its negative and positive parts, while the theists will embrace the critique of materialist naturalism while rejecting his panpsychism and natural-teleologism.

Plantinga's review, like ancient Gaul, est in partes tres divisa.

In the first part, Plantinga take himself to be in agreement with Nagel on four points. (1) It is extremely improbable that life could have arisen from inanimate matter by the workings of the laws of physics and chemistry alone. (2) But supposing life has arisen, then natural selection can go to work on random genetic mutations. Still, it is incredible that that all the fantastic variety of life, including human beings, should have arisen in this way. (3) Materialist naturalism cannot explain consciousness. (4) Materialist naturalism cannot explain belief, cognition, and reason.

In the second part of his review, Plantinga discusses Nagel's rejection of theism. Apart from Nagel's honestly admitted temperamental disinclination to believe in God, Plantinga rightly sees Nagel's main substantive objection to theism to reside in theism's putative offense against the unity of the world. But at this point I hand off to myself. In my post Nagel's Reason for Rejecting Theism I give a somewhat more detailed account than does Plantinga of Nagel's rejection.

In the third part of his review, Plantina expresses his doubts about panpsychism and natural teleology. I tend to agree that there could not be purposes without a purposer:

As for natural teleology: does it really make sense to suppose that the world in itself, without the presence of God, should be doing something we could sensibly call “aiming at” some states of affairs rather than others—that it has as a goal the actuality of some states of affairs as opposed to others? Here the problem isn’t just that this seems fantastic; it does not even make clear sense. A teleological explanation of a state of affairs will refer to some being that aims at this state of affairs and acts in such a way as to bring it about. But a world without God does not aim at states of affairs or anything else. How, then, can we think of this alleged natural teleology?

Plantinga ends by suggesting that if it weren't for Nagel's antipathy to religion, his philosophical good sense would lead him to theism.

My posts on Nagel's book are collected here.

Addendum (11/19): In case you missed it, Nagel reviewed Plantinga.

What is Reason? How Did it Arise? Nagel and Non-Intentional Teleology

This is the sixth in a series of posts, collected here, on Thomas Nagel's Mind and Cosmos (Oxford 2012). In my last post I suggested that Nagel needs a principle of plenitude in order to explain the actual existence, as opposed to the mere possibility, of rational organisms. But maybe not, maybe teleology will turn the trick for him. So we need to see what he says about teleology.

Nagel distinguishes "constitutive" from "historical" questions. What is reason? is an example of the former; How did reason arise? of the latter. Now one might wonder whether reason is the sort of thing that could arise. I am tempted to say that reason could no more arise than truth could arise, but then I'm a theist. Nagel, however, must hold that reason arises given his monism. As a monist, he maintains that there is exactly one world, this natural world.

Off the top of my head, I suggest we have at least six options concerning the nature and origin of reason.

A. Interventionist Theism. Reason didn't arise, but always existed. God is its prime instance and source. Reason in us did not arise or emerge from irrational or pre-rational elements but was implanted by God in us. It is part of what makes us of higher origin, an image and likeness of God.

B. Noninterventionist Deism. Reason didn't arise, but always existed. God is its prime instance and source. But God did not infuse or implant reason in certain animals at any point in the evolutionary process; what he did is rig up the world in such a way that rational animals would eventually emerge. Nagel mentions something like this possibility on p. 95.

C. Transcendental Subjectivism. Reason didn't arise, but neither is God its prime instance and source. Reaon is an a priori structure of our subjectivity, a transcendental presupposition without which we cannot carry out our cognitive operations. A view like this could be read out of Kant. A transcendental idealism as opposed to the Hegelian objective idealism that Nagel supports. (17)

D. Reason is a fluke. Reason arose, but it was a cosmic accident. That there are rational beings is simply a brute fact. Nagel rightly rejects this view.

E. Materialist evolutionary naturalism operating by "directionless physical law." (p. 91)

F. Nature-immanent non-intentional teleology.

Nagel rejects all of these options except the last. Unfortunately, Nagel's proposal is so sketchy it is hard to evaluate. To get a handle on it we need to study Nagel's final chapter on value in a separate post. According to natural teleology, the world has an in-built propensity to give rise to beings for whom there is a difference between what is good for them and what is bad for them. There is no agent who intends that such beings should arise; there is just this tendency toward them in nature below the level of mind. And so the explanation of the existence of such beings is not merely causal but teleological: there is is a sort of axiological requiredness in rerum natura that pulls as it were from the future these beings into existence. (See p. 121) This is my way of putting it.

Why Can’t Reason Be a Fluke? Intelligibility and the Existence of Rational Animals

This is the fifth in a series of posts, collected here, on Thomas Nagel's Mind and Cosmos. The question that concerns me in this entry is whether we can forge a link between the intelligibility of nature and the existence of rational beings.

For Nagel, the existence of rational animals is not a brute fact or fluke or cosmic accident. Nagel's somewhat sketchy argument (see p. 86) is along these lines:

1. There are organisms capable of reason.
2. The possibility of such beings must have been there from the beginning.
3. This possibility, however, must be grounded in and explained by the nature of the cosmos.
4. What's more, the nature of the cosmos must explain not only the possibiity but also the actuality of rational animals: their occurrence cannot be a brute fact or cosmic accident.

I take Nagel to be maintaining that the eventual existence of some rational beings or other is no accident but is included in the nature of things from the beginning — which is consistent with maintaining that there is an element of chance involved in the appearance of any particular instance of reason such as Beethoven. So eventually nature must produce beings capable of understanding it. We are such beings. "Each of our lives is part of the lengthy process of the universe waking up and becoming aware of itself." (85)

Nagel's thesis is not obvious. Why can't reason be a fluke? Even if we grant Nagel that the intelligibility of nature could not have been a fluke or brute fact, how does it follow that the actual existence of some rational beings or other, beings capable of 'glomming onto' the world's intelligible structure, is not a fluke? Nagel's argument needs some 'beefing up' so that it can meet this demand.

1. Let's start with the idea that nature is intelligible. Why? That the world is intelligible is a presupposition of all inquiry. The quest for understanding rests on the assumption that the world is understandable, and indeed by us. The most successful form of this quest is natural science. The success of the scientific quest is evidence that the presupposition holds and is not merely a presupposition we make. The scientific enterprise reveals to us an underlying intelligible order of things not open to perception alone, although of course the confirmation of scientific theories requires perception and the various instruments that extend it.

2. Now what explains this underlying rational order? Two possibilities. One is that nothing does: it's a brute fact. It just happens to be the case that the world is understandable by us, but it might not have been. The rational order of things underpins every explanation but itself has no explanation. The other possibility is that the rational order has an explanation, in which case it has an explanation by something distinct from it, or else is self-explanatory. On theism, the world's rational order is grounded in the divine intellect and is therefore explained by God. On what I take to be Nagel's view, the rational order is self-explanatory, a necessary feature of anything that could count as a cosmos.

Nagel views the intelligibility of the world as "itself part of the deepest explanation why things are as they are." (17). Now part of the way things are is that they are understandable by us. Given that the way things are is intelligible, it follows that the intelligibility of the world is self-explanatory or self-grounding.

Our second premise, then, is that the intelligibilty of the world is self-explanatory, hence a necessary feature of anything that could count as a cosmos.

3. Our third premise is that intelligibility is an an inherently mind-involving notion. Necessarily, if x is intelligible, then x is intelligible to some actual or possible mind. Nothing is understandable unless it is at least possible that there exist some being with the power of understanding.

The conjunction of these three premises entails the possibility of rational beings, but not the actuality of them. There would seem to be a gap in Nagel's reasoning. The world is intelligible, and its intelligibility is a necessary feature of it. From this we can infer that, necessarily, if the cosmos exists, then it is possible that there be rational beings. But that is as far as we can get with these three premises.

4. What Nagel seems to need is a principle of plenitude that allows us to pass from the possibility of rational beings to their actual existence. J. Hintikka has ascribed to Aristotle a form of the principle according to which every genuine possibility must at some time become actual. This would do the trick, but to my knowledge Nagel make no mention of any such principle.

5. I suggest that theism is in a better position when it comes to explaining how both intelligibility and mind are non-accidental. Intelligibility is grounded in the divine intellect which necessarily exists. So there must be at least one rational being. We exist contingently, but the reason in us derives from a noncontingent source.
