John Searle Interviewed

Searle with gunThis shot of the old philosopher by the fire with his shootin' ahrn nicely complements some of the combative things he says in the Zan Boag interview at NewPhilosopher.  (HT: Karl White.) For example, "I don’t read much philosophy, it upsets me when I read the nonsense written by my contemporaries, the theory of extended mind makes me want to throw up…so mostly I read works of fiction and history."

The surly (Searle-y?) reference is to externalist theories of mind such as Ted Honderich's and Clark and Chalmers' The Extended Mind.

I found this exchange interesting:

You say that consciousness is a real subjective experience, caused by the physical processes of the brain, and that where consciousness is concerned, the appearance is reality. Can you elaborate on this?

John Searle: Consciousness exists only insofar as it is experienced by a human or animal subject. OK, now grant me that consciousness is a genuine biological phenomenon. Well, all the same it’s somewhat different from other biological phenomena because it only exists insofar as it is experienced. However, that does give it an interesting status. You can’t refute the existence of consciousness by showing that it’s just an illusion because the illusion/ reality distinction rests on the difference between how things consciously seem to us and how they really are. But where the very existence of consciousness is concerned, if it consciously seems to me that I’m conscious, then I am conscious. You can’t make the illusion/reality distinction for the very existence of consciousness the way you can for sunsets and rainbows because the distinction is between how things consciously seem and how they really are.

You also say that consciousness is a physical property, like digestion or fire.

John Searle: Consciousness is a biological property like digestion or photosynthesis. Now why isn’t that screamingly obvious to anybody who’s had any education? And I think the answer is these twin traditions. On the one hand there’s God, the soul and immortality that says it’s really not part of the physical world, and then there is the almost as bad tradition of scientific materialism that says it’s not a part of the physical world. They both make the same mistake, they refuse to take consciousness on its own terms as a biological phenomenon like digestion, or photosynthesis, or mitosis, or miosis, or any other biological phenomenon.

Part of what Searle says in his first response is importantly correct.  Since the distinction between illusion and reality presupposes the reality of consciousness, it makes no sense to suppose that consciousness might be an illusion, let alone assert such a monstrous thesis.  It amazes me that there are people who are not persuaded by such luminous and straightforward reasoning.  But pace Searle it does not follow that consciousness is a biological phenomenon.  If biological phenomena are those phenomena that are in principle exhaustively intelligible in terms of the science of biology, then I don't see how consciousness could be biological even if it is found only in biologically alive beings.  Can the what-it-is-like feature be accounted for in purely biological terms?  (That's a rhetorical question.)  And that's just for starters.

In the second response, Searle claims that consciousness is a biological property and that this ought to be  "screamingly obvious" to anyone with  "any education."  Come on, John!  Do you really want to suggest that the philosophical problem of consciousness as this is rigorously formulated by people like Colin McGinn is easily solved just be getting one's empirical facts straight?  Do you really mean  to imply that people who do not agree with your philosophy of mind are ignorant of plain biological facts?  If consciousness were a biological phenomenon just like digestion or photosynthesis or mitosis or meiosis, then consciousness would be as unproblematic as the foregoing.  It isn't. 

Why is it that there is a philosophical problem of consciousness, but no philosophical problem of digestion?  Note the obvious difference between the following two questions.  Q1: How is consciousness possible given that it really exists, arises in the brain, but is inexplicable in terms of  what we know and can expect to know about animal and human brains?  Q2: How is digestion possible given that it really exists, takes place in the stomach and its 'peripherals,' but is inexplicable in terms of what we know and can know about animal and human gastrointestinal systems? 

Obviously, there is a philosophical problem about consciousness but no philosophical problem about digestion.  And note that even if some philosopher argues that there is no genuine philosophical problem about consciousness, because one has, say, been bewitched by language, or has fallen afoul of some such draconian principle as the Verifiability Criterion of Cognitive Meaningfulness,  no philosopher would  dream of arguing that there is no genuine philosophical problem of digestion.  It needs no arguing.  For whether or not there is a genuine problem about consciousness, there is a putative problem about it.  But there is not even a putative philosophical problem about digestion. The only problems concerning digestion are those that can be solved by taking an antacid or by consulting a gastroenterologist or by doing more empirical gut science.

This is why it is at least possible with a modicum of sense to argue that the philosophy of mind collapses into the neuroscience of the brain, but impossible sensibly to argue that the the philosophy of digestion collapses into gastroenterology or that the philosophy of blood filtering and detoxification collapses into hepatology.  There is no philosophy of digestion or philosophy of blood filtering and detoxification.

It is obviously not obvious that consciousness is a biological phenomenon.  Searle is brilliant when it comes to exposing the faults of other theories of mind, but he is oblivious to the problems with his own. Searle 'knows' in his gut that naturalism just has to be true, which is why he cannot for a second take seriously any suggestion that consciousness might have a higher origin.  But he ought to admit that his comparison of consciousness to digestion and photosynthesis and mitosis and meiosis is completely bogus.  He can still be a naturalist, however, either by pinning his hopes on some presently incoceivable future science or by going mysterian in the manner of  McGinn.

More on Searle in my appropriately appellated Searle category.

Christian Physicalism?

J. P. Moreland is against it.  Me too.  More generally, I oppose any amalgamation of classical theism and materialism about the mind.  (See my "Could a Classical Theist be a Physicalist?" Faith and Philosophy, vol. 15, no. 2, April 1998, pp. 160-180.) Here are some  excerpts from Moreland's piece:

Christianity is a dualist, interactionist religion in this sense:  God, angels/demons, and the souls of men and beasts are immaterial substances that can causally interact with the world.  Specifically, human persons are (or have) souls that are spiritual substances that ground personal identity in a disembodied intermediate state between death and final resurrection . . . .

[. . .]

In my view, Christian physicalism involves a politically correct revision of the biblical text that fails to be convincing . . . .

[. . .]

The irrelevance of neuroscience also becomes evident when we consider the recent best seller Proof of Heaven by Eben Alexander.  Regardless of one’s view of the credibility of Near Death Experiences (NDEs) in general, or of Alexander’s in particular, one thing is clear.  Before whatever it was that happened to him (and I believe his NDE was real but no not agree with his interpretation of some of what happened to him), Alexander believed the (allegedly) standard neuroscientific view that specific regions of the brain generate and possess specific states of conscious.  But after his NDE, Alexander came to believe that it is the soul that possesses consciousness, not the brain, and the various mental states of the soul are in two-way causal interaction with specific regions of the brain.  Here’s the point:  His change in viewpoint was a change in metaphysics that did not require him to reject or alter a single neuroscientific fact.  Dualism and physicalism are empirically equivalent views consistent with all and only the same scientific data.  Thus, the authority of science cannot be appropriated to provide any grounds whatsoever for favoring one view over another.

I'm with J.P on the irrelevance of neuroscience to the philosophy of mind, and vice versa, but with three minor exceptions that I explain in the third article cited below.

Sophistry in True Detective: On the Supposed Illusion of Having a Self

The other day I referred to the following bit of dialogue from the new HBO series, True Detective, as sophistry. Now I will explain why I think it to be such.  Here is the part I want to focus on.  The words are put in the mouth of the anti-natalist Rustin Cohle.  I've ommitted the responses of the Woody Harrelson character.

I think human consciousness is a tragic misstep in  evolution. We became too self aware; nature created an aspect of nature separate from itself. We are creatures that should not exist by natural law. We are things that labor under the illusion of having a self, a secretion of sensory experience and feeling, programmed with total assurance that we are each somebody, when in fact everybody’s nobody. I think the honorable thing for our species to do is deny our programming, stop reproducing, walk hand in hand into extinction, one last midnight, brothers and sisters opting out of a raw deal.

Sorting through this crap is as painful as reading the typical student paper.  Where does one start with such a farrago of Unsinn?  But here goes. The main points made above are these:

1. The emergence of consciousness and self-consciousness in human animals is an accident, a fluke of evolution.

2. We are each under the illusion of having, or being, a self when in fact there are no selves.

3. We have been programmed by nature to suffer from this illusion.

4. The honorable thing to do is to deny our programming, refuse to procreate, and embrace our extinction as a species.

Each of these theses is either extremely dubious or demonstrably incoherent, taken singly, not to mention the dubiousness of the 'is'-'ought' inference from (3) to (4).  But in this entry I will address (2) alone.

'There are no selves' is what our anti-natalist means when he say that everybody is nobody.  For it is a Moorean fact, undeniable even by our anti-natalist, that every living human body is some living human body or other.  He is not denying that plain fact but that these living human bodies are selves. 

Performative Inconsistency

Now 'There are no selves,' if asserted  by a being  who understands what he says and means what he says, is asserted by a conscious and self-conscious being.  But that is just what a self is.  A self is a conscious being capable of expressing explicit self-consciousness by the use of the first-person singular pronoun, 'I.'  Therefore, a self that asserts that there are no selves falls into performative inconsistency.  The very act or performance of asserting that there are no selves or that one is not a self falsifies the content of the assertion.  For that performance is a performance of a self.

The claim that there are no selves is therefore self-refuting.

Assertion is a speech act.  But we get the same result if one merely thinks the thought that one is not a self without expressing it via an assertive utterance.  If I think the thought *I am not a self,* then that thought is falsified by the act of thinking it since the act is the act of a self.

The point can also be made as follows.  If there are no selves, then I am not a self.  But if I am not a self, then I do not exist.  Perhaps some living human body exists, but that body cannot be my body if I do not exist.  What makes this body my body is its connection with me.  So I must exist for some body to be my body.  My body is my body and not my body's body.  So I am not identical to my  body.  I have a body.   'This body is this body' is a tautology. 'I am this body' is not a tautology. If I exist, then I am distinct from my body and from any body.

So if I am not a self, then I do not exist.  But the thought that I do not exist is unthinkable as true.  Only I can think this thought, and my thinking of the thought falsifies its content, and this is so even if 'I' picks out merely a momentary self.  (I am not committed by this line of reasoning to a substantial self that remains numerically the same over time.)  So we have performative inconsistency. 

This reasoning does not show that I am a necessary being, or that I have or am an immortal soul, or even that I am a res cogitans in Descartes' sense.  What it shows is that the self cannot be an illusion.  It shows that anyone who carefully considers whether or not he is a self can attain the certain insight that he is at least as long as he is thinking these thoughts. 

Soviel Schein, soviel Sein

There is another way of looking at it.  If each of us is under the illusion of having a self or being a self, then who is being fooled?  To whom does this false seeming appear?  There cannot be illusions in a world without conscious beings.  An illusion by its very nature is an illusion to consciousness.  So if consciousness is an illusion, then it is not an illusion.  The same holds for the self.  If the self is an illusion, then the self is not an illusion.

There cannot be Schein (illusion) without Sein (being).  "So much seeming, so much being."

 

Conscience, Brain, and Scientistic Pseudo-Understanding

One of the tasks of philosophy is to expose and debunk bad philosophy.  And there is a lot of it out there, especially in the writings of journalists who report on scientific research.  Scornful of philosophy, many of them peddle scientistic pseudo-understanding without realizing that what they sell is itself philosophy, very bad philosophy.  A particularly abysmal specimen was sent my way by a reader.  It bears the subtitle: "Without recognising it, Oxford scientists appear to have located the consience [sic]."  In the body of the article we read:

This isn't some minor breakthrough of cognitive neuroscience. This is about good and bad, right and wrong. This is about the brain's connection to morality. This means that the Oxford scientists, without apparently realising what they've done, have located the conscience. 

For centuries we thought that the conscience was just some faculty of moral insight in the human mind, an innate sense that one was behaving well or badly – although the great HL Mencken once defined it as, "the inner voice which  warns us that someone may be looking". It's been used by religions as a numinous something-or-other, kindly bestowed by God, to give humans a choice between sin and Paradise.

Now, thanks to neuroscience, we've found the actual, physical thing itself. It's a shame that it resembles a Brussels sprout: something so important and God-given should look more imposing, like a pineapple. But then it wouldn't fit in our heads.

Henceforth, when told to "examine our conscience", we won't need to sit for hours cudgelling our brains to decide whether we're feeling guilty about accessing YouPorn late at night; we can just book into a clinic and ask them for a conscience-scan, to let us know for sure.

Part of what is offensive about this rubbish is that a great and humanly very important topic is treated in a jocose manner.  (I am assuming, charitably, that the author did not write his piece as a joke.) But that is not the worst of it.  The worst of it is the incoherence of what is being proposed.

I'll begin with what ought to be an obvious point.  Before we can locate conscience in the brain or anywhere else we ought to know, at least roughly, what it is we are talking about.  What is conscience?

Conscience is the moral sense, the sense of right, wrong, and their difference.  It is the sense whereby we discern, or attempt to discern, what is morally (not legally, not prudentially) permissible, impermissible, and obligatory.  It typically results in moral judgements about one's thoughts, words and deeds  which in turn eventuate in resolutions to amend or continue one's practices.

The deliverances of conscience may or may not be 'veridical' or revelatory of objective moral demands or or objective moral realities on particular occasions.  Some people are 'scrupulous': their consciences bother them when they shouldn't.  Others are morally insensitive: their consciences do not bother them when they should.  If subject S senses, via conscience, that doing/refraining from X is morally impermissible, it does not follow that it is.  Conscience is a modality of object-directed consciousness and so may be expected to be analogous to nonmoral consciousness:  if I am thinking that a is F, it does not follow that a is F.

So  just as we can speak of the intentionality of consciousness, we can speak of the intentionality of conscience.  Pangs of conscience are not non-intentional states of consciousness like headache pains.  Conscience purports to reveal something about the morally permissible, impermissible, and obligatory (and perhaps also about the supererogatory and suberogatory); whether it does so is a further question.  Suppose nothing is objectively right or wrong.  That would not alter the fact that there is the moral sense in some of us.

Can conscience be located in the brain and identified with the lateral frontal pole?  If so, then a particular moral sensing, that one ought not to have done X or ought to have done Y, is a state of the brain.  But this is impossible.  A particular moral sensing is an intentional (object-directed) state.  But no physical state is object-directed.  So, by the Indiscernibility of Identicals, a moral sensing cannot be a brain state. 

So that is one absurdity.  A second is that it is absurd to suggest, as the author does, that one can examine one's conscience by examining a part of one's brain.   Examination of conscience is a spiritual practice whereby, at the end of the day perhaps, one reviews and morally evaluates the day's thoughts, words, and deeds.  What is being examined here?  Obviously not some bit of brain matter.  And if one were to examine that hunk of meat, one would learn nothing as to the thoughts, words, and deeds of the person whose hunk of brain meat it is.

If a person's feeling of guilt is correlated with an identifiable brain state, then one could perhaps determine that a person was feeling guilt by way of a brain scan.  But that would provide no insight into (a) what the guilt is about, or (b) whether the guilt is morally appropriate.  No brain scan can reveal the intentionality or the normativity of guilt feelings.

There is also a problem about who is doing the examining in an examination of conscience. A different hunk of meat, or the same hunk?  Either way, absurdity.  Examining is an intentional state.  So, just as it is absurd to suppose that one's thoughts, words, and deed are to be found in the lateral frontal pole, it is also absurd to suppose that that same pole is doing the examining of those contents.

I have emphasized the intentionality of conscience, which fact alone sufficies to refute the scientistic nonsense.  And I have so far bracketed the question whether conscience puts us in touch with objective moral norms.  I say it does, even though how this is possible is not easy to explain.  Well, suppose that torturing children to death for sexual pleasure  is objectively wrong, and that we have moral knowledge of this moral fact via conscience.

Then two problems arise for the scientistic naturalist:  how is is possible for a hunk of meat, no matter how wondrously complex, to glom onto these nonnatural moral facts? And second, if there are such facts to be accessed via conscience, how do they fit into the scientistic naturalist's scheme?  Answers:  It is not possible, and they don't.

Have I just wasted my time refuting rubbish beneath refutation?  Maybe not.  Scientism, with its pseudo-understanding poses a grave threat to the humanities and indeed to our very humanity.  David Gelernter is good on this.

On Seeing: Intentionality without Aspectuality?

Consider this argument:

1. Tom believes that the man at the podium is the Pope

2. The Pope is an Argentinian

Therefore

3. Tom believes that the man at the podium is Argentinian.

The argument is plainly invalid.  For Tom may not believe that the Pope is an Argentinian.  Now consider this argument:

4. Tom sees the Pope

2. The Pope is an Argentinian

Therefore

5. Tom sees an Argentinian.

Valid or invalid?  That depends.  'Sees' is often taken to be a so-called verb of success:  if S sees x, then it follows that x exists.  On this understanding of  'sees' one cannot see what doesn't  exist. Call this the existentially loaded sense of 'sees' and contrast it with the existentially neutral sense according to which 'S sees x' does not entail 'X exists.'

If 'sees' is  understood in the existentially loaded way, then the second argument is valid, whether or not Tom knows that the Pope is Argentinian.    For if Tom sees the Pope, then the object seen exists.  But nothing can exist without properties, properties most of which  are had independently of our mental states.  If the object has the property F-ness, then the perceiver sees an F-thing, even if he doesn't see it as an F-thing.  So Tom sees an Argentinian despite not seeing him as an Argentinian.

Now seeing in the existentially loaded sense might seem to be a perfectly good example of an intentional or object-directed state since one cannot see without  seeing something. One cannot just see.  Seeing takes an object. 

But whether existentially loaded seeing is an intentional state depends on what all enters into the definition of an intentional state.  Now one mark of intentionality is aspectuality.  What I am calling aspectuality is what John Searle calls "aspectual shape":

I have been using the term of art, "aspectual shape," to mark a universal feature of intentionality.  It can be explained as follows: Whenever we perceive anything or think about anything, we always do so under some aspects and not others.  These aspectual features are essential to the intentional state; they are part of what makes it the mental state that it is. (The Rediscovery of the Mind, MIT Press, 1992, pp. 156-157)

IMG_0882The phrase I bolded implies that no intentional state is such that every aspect of  the object is before the mind of the person in the state.  Suppose you see my car.  You won't help being able to see it is as bright yellowish-green sport-utility vehicle.  But you could easily see it without seeing it as a 2013 Jeep Wrangler.  I take this to imply that the set of perceived aspects of any object of perception not only can be but must be incomplete. This should  be obvious from the fact that, as Husserl liked to point out, outer perception is essentially perspectival.  For example, all sides of the car are perceivable, but one cannot see the car from the front and from the rear simultaneously. 

This aspectuality holds for  intentional states generally.  To coin an example, one can believe that a certain celestial body is the Evening Star without believing that it is the Morning Star.  One can want to drink a Manhattan without wanting to drink a mixture of bourbon, sweet vermouth, and Angostura bitters. As Searle says, "Every belief and every desire, and indeed every intentional phenomenon, has an aspectual shape." (157)

Intentional states are therefore not only necessarily of something; they are necessarily of something as something.  And given the finitude of the human mind, I want to underscore the fact that  even if every F is a G, one  can be aware of x as F without being aware of  x as G.   Indeed, this is so even if necessarily (whether metaphysically or nomologically) every F is a G. Thus I can be aware of a moving object as a cat, without being aware of it as spatially extended, as an animal, as a mammal, as an animal that cools itself by panting as opposed to sweating, as my cat, as the same cat I saw an hour ago, etc.

But now it seems we have a problem.  If that which is (phenomenlogically, not spatially) before my mind is necessarily property-incomplete, then either seeing is not existentially loaded, or existentially loaded seeing is not an intentional state.  To put the problem as an aporetic tetrad:

1. If S sees x, then x exists

2. Seeing is an intentional state

3. Every intentional state has an aspectual shape: its object is incomplete

4. Nothing that exists is incomplete.

The limbs of the tetrad are collectively logically inconsistent.  Any three of them, taken together, entails the negation of the remaining one.  For example, the conjunction of the first three limbs entails the negation of the fourth.

But while the limbs are collectively inconsistent, they are individually very plausible. So we have a nice puzzle on our hands.  At least one of the limbs is false, but which one?   I don't think that (3) or (4) are good candidates for rejection.  That leaves (1) or (2).

I incline toward the rejection of (1).  Seeing is an intentional state but it is not  existence-entailing.  My seeng of x does not entail the existence of x.  What one sees (logically) may or may not exist.  There is nothing in or about the visual object that certifies that it exists apart from my seeing it. Existence is not an observable feature.  The greenness of the tree is empirically accessible; its existence is not.

It is of course built into the intentionality of outer perception that what is intended is intended as existing whether or not the act or intentio exists.  To put it paradoxically (and I owe this formulation to Wolfgang Cramer), the object intended is intended as non-object.  That is, objects of outer perception are intended as existing independently of the mental acts that 'target' them, and thus not as merely intentional objects.  But there is nothing like an 'ontological argument' in the vicinity.  I cannot validly infer that the tree I see exists because it is intended as existing apart from my seeing.  This is is an invalid 'ontological' inference:

A. X is intended as existing independently of any  and all mental acts

ergo

B. X exists.

If the above is right, then seeing is an intentional state that shares the aspectuality common to all such states.  A consequence of this is a rejection of  'externalism' about outer perception: the content of the mental state I am in when I see a tree does not depend on the existence of any tree.  The object-directedness of the mental state is intrinsic to it and not dependent on any extrinsic relation to a mind-independent item.  To turn Putnam on his head: the meaning is precisely 'in the head.' 

Are there problems with this?  We shall see.  Externalism is a fascinating option.  But I am highly annoyed that that typical analytic philosopher, Ted Honderich, who defends a version of externalism in his book On Consciousness, makes no mention of the externalist theories of Heidegger, Sartre or Butchvarov.  How typical of the analytic ignoramus, not that all 'analysts' are ignorant of the history of philosophy.

Mind and Matter

Here are a couple of theses that are part of my credo, though I do not merely believe them, but think I have good reasons for believing them:

Thesis 1:  One cannot get mind from matter no matter how the matter is arranged  or how complexly arranged.  That mind should arise from matter is unintelligible.

To appreciate the force of this thesis, let's run through some objections.  And I do mean run: what follows has to be cursory.

Objection 1.  "There is no question of getting mind from matter; mental states and properties  just are states and properties of the material world, patterns of behavior perhaps, or patterns of neural activity."

Response 1.  Of course I reject identity theories that reduce the mental to the physical, whether they be type-type identity theories or merely token-token identity theories.  I have written an 'unconscionable' number of posts on this topic I and am not inclined to repeat myself in any detail.  But if you tell me that, say, my thinking about Prague is identical to a complex state of my brain, I would dismiss that as obvious nonsense and for a very good reason.  My occurent thinking, at this moment, is of or about or directed to  an object that, for all I know, was nuked out of existence — God forbid — a second ago and this without prejudice to my act of thinking's now being about precisely the object it is about.    Now this intrinsic object-directedness  or intrinsic intentionality of my act of thinking — to use the philosopher's term of art — is not a property that it makes any sense to ascribe to any physical object or state. Now if x has a property that y lacks, or vice versa, then of course x cannot be identical to y.

Objection 2.  "There simply are no mental states as you claim, and the argument from intentionality you give can be run in reverse so as to prove it."

Response 2.  The objector is suggesting the following argument: "(1) If mental states such as thinking about Prague are anything, then they are brain states; (2) such mental states exhibit intrinsic intentionality; (3) no physical state, and thus no brain state, exhibits intrinsic intentionality; therefore (4) there are no mental states."

This eliminativist argument issues in a conclusion that is obviously, breathtakingly false, and so one of the premises must be false.  The stinker is of course (1).

Objection 3.  "Granted, it is unintelligible that mind should arise from matter as conceived in current physics.  But the matter that we know might hide and contain within itself occult powers beyond the ken of current or any future physics, including the power to give rise to mind."

Reply 3.  The game is up when materialists reach for occult powers.  The only matter we know about is the matter of ordinary experience and physics.  And there is no place in matter so conceived for occult powers that give rise to mind. If you tell me that what thinks when I think is an intracranial hunk of meat, then you are ascribing  a power to matter that destroys the very concept of matter that you started with and that you need to articulate your materialism.

Thesis 2:  That matter should arise from mind is not unintelligible. 

Why not?  Because intrinsic to mind is object-directedness, or object-positing.  Mind by its nature is of objects distinct from mind.  Mind has the power to create objects distinct from itself and its states.  This power is not occult.  It is open to us in reflection.  The entire material cosmos could be be just a huge system of intentional objects for a sufficiently capacious and powerful mind.  The thought is thinkable.  It is intelligible.  That is not to say it is true or to say that we have good reasons for believing it.  It has its difficulties, but  it makes sense in the way it makes no sense to maintain that mind arises from matter.  That is an absurdity that can be seen to be such by hard thinking.

So we get an asymmetry.  Matter could, for all we know, be the product of mind, but mind could not, for all we know, be the product of matter.

Ted Honderich is One Quirky Writer

HonderichI am reading Ted Honderich, On Consciousness (Edinburgh UP, 2004) and trying to get a handle on just what his theory of consciousness as existence amounts to.  An awkward and quirky writer, he doesn't make things easy on the reader, and doesn't seem to realize  that in this very fast brave new world of ours the writer must get to  the point without unnecessary circumlocution if he wants to keep his reader glued to the page.  Here is an example of Honderich's style, from p. 206:

The other option from spiritualism now deserves the name of being devout physicalism. You can say and write, in a career that keeps an eye on some of science, maybe two, and is forgetful of reflective experience, that being conscious or aware of something is only having certain physical properties in the head. Usually this cranialism is a matter of only neural properties as we know them — thought of computationally or with microtubules to the fore or in any other way you like.

[Note the awkward placement of "Maybe two." It belongs right after "eye."]

Nobody not on the philosophical job of trying to approximate more to some of science or horse sense believes this either. We all know, to make use of a pefectly proper and enlightening parody,  that consciousness, isn't just cells, however fancily or fancifully conceived. Everybody on the job tries to give a place to or register what they know when they're not on the job. But they can't do it if they have it that consciousness has only neural properties or conceivably silicon or otherwise physical properties, no matter how they are conceived additionally.

Honderich's thought is not so much expressed as buried in the above  mess of verbiage. Here is the thought which is correct as far as it goes expressed in three sentences.

Devout physicalism is the main alternative to spiritualism, or substance dualism.  But only someone who fails to reflect on his actual experience could suppose that being conscious of something is a matter of the instantiation of neural properties in the brain.  Both philosopher and layman know that consciousness is not brain cells, but the philosopher trying to be scientific is apt to forget it.

Here is Colin McGinn's savage review of Honderich's book.  Be aware that there is personal animus between the two men.

On Multiplying Modes of Existence

UnicornAm I committed to an uneconomical multiplication of modes of existence?  I said that the following set of propositions is logically consistent:

a. Tom is thinking of a unicorn
b. Unicorns do not exist in reality
c. Tom's mental state is object-directed; it is an intentional state.
d. The object of Tom's mental state does not exist in reality.
e. The merely intentional object is not nothing.
f. The merely intentional object enjoys intentional existence, a distinct mode of existence different from existence in reality.

David Brightly in a comment constructs a similar set:

By analogy with your (a)–(f) can we not also consistently assert the following?

a. This tapestry, rather beautifully, depicts a unicorn.
b. Unicorns do not exist in the (C1)-sense.
c. The tapestry is object-directed; it is a depictional entity.
d. The object of the tapestry does not (C1)-exist.
e. The merely depicted object is not nothing.
f. The merely depicted object enjoys depictional existence, a distinct mode of existence different from (C1)-existence.

Likewise,

Whereas my view is that when Tom thinks of a unicorn, he is thinking of something, an item that exists merely as the object of Tom's act of thinking, but does not exist mind-independently,

has the analogy,

When the tapestry depicts a unicorn, it is depicting something, an item that exists merely as the object of the tapestry's depicting, but does not exist tapestry-independently.

Three points.

First, the intentionality of Tom's thinking is original while the intentionality of the tapestry is derivative.  The tapestry is not intrinsically  intentional, but derives its intentionality from a mind's taking of the merely physical object as a picture or image of something else.  By itself, the tapestry depicts nothing.  It is just a piece of cloth.

Given the first point, my second is that there are not two kinds of intentionality or object-directedness, but only one, the intentionality of the viewer of the tapestry who takes it as representing something, a unicorn. 'Derivative' in 'derivative intentionality' is an alienans adjective.

Third, if there are not two kinds of intentionality, then there is no call to distinguish, in addition to (C1)-existence (real existence) and intentional existence, depictional existence.

In this way I think I can avoid multiplying modes of existence by the multiplicity of types of physical things (scribbles on paper, trail markers, grooves in vinyl, etc.) that can be taken to represent something.

Sexuality and Sex Organs

Can one learn all about human sexuality by studying the human organs of generation?  The very notion is risible.  Can one learn all about human affectivity by studying that most reliable and indefatigable of pumps, the human heart?  Risible again.  It is similarly risible  to think that one can learn all about the mind by studying that marvellously complex hunk of meat, the brain.

 

Paul Churchland on Eliminative Materialism

Via Ed Feser, I see that that Paul Churchland's Matter and Consciousness has appeared in a third edition.  Just what the world needs.  I concur with Ed's judgment:

The only thing more outrageous than Churchland’s persistence in superficiality and caricature would be the continued widespread use of his book as a main text for introductory courses in philosophy of mind — at least if it were not heavily supplemented with readings that correct his errors, and actually bother to present the main arguments for dualism.  

To 'celebrate' this great event in the publishing world, I post a revised version of an entry from about five years ago: 

The most obvious objection to eliminative materialism (EM) is that it denies obvious data, the very data without which there would be no philosophy of mind in the first place. Introspection directly reveals the existence of pains, anxieties, pleasures, and the like. Suppose I have a headache. The pain, qua felt, cannot be doubted or denied. Its esse is its percipi. To identify the pain with a brain state makes a modicum of sense, at least initially; but it makes no sense at all to deny the existence of the very datum that gets us discussing this topic in the first place. But Paul M. Churchland (Matter and Consciousness, rev. ed. MIT Press, 1988, pp. 47-48) has a response to this sort of objection:



The eliminative materialist will reply that that argument makes the same
mistake that an ancient or medieval person would be making if he insisted that
he could just see with his own eyes that the heavens form a turning sphere, or
that witches exist. The fact is, all observation occurs within some system of
concepts, and our observation judgments are only as good as the conceptual
framework in which they are expressed. In all three cases — the starry sphere,
witches, and the familiar mental states — precisely what is challenged is the
integrity of the background conceptual frameworks in which the observation
judgments are expressed. To insist on the validity of one's experiences,
traditionally interpreted, is therefore to beg the very question at issue. For
in all three cases, the question is whether we should reconceive the
nature of some familiar observational domain.

Even if we grant that "all observation occurs within some system of concepts," is the experiencing of a pain a case of observation? If you know your Brentano, you know that early on in Psychology From an Empirical Standpoint he makes a distinction between inner observation (innere Beobachtung) and inner perception (innere Warhnehmung). Suppose one suddenly becomes angry. The experiencing of anger is an inner perception, but not an inner observation. The difference is between living in and through one's anger and objectifying it in an act of reflection. The act of inner observation causes the anger to subside, unlike the inner perception which does not.

Reflecting on this phenomenological difference, one sees how crude Churchland's scheme is. He thinks that mental data such as pains and pleasures are on a par with outer objects like stars and planets. It is readily granted with respect to the latter that seeing is seeing-as. A medieval man who sees the heavens as a turning sphere is interpreting the visual data in the light of a false theory; he is applying an outmoded conceptual framework. But there is no comparable sense in which my feeling of pain involves the application of a conceptual framework to an inner datum.

Suppose I feel a pain. I might conceptualize it as tooth-ache pain in which case I assign it some such cause as a process of decay in a tooth. But I can 'bracket' or suspend that conceptualization and consider the pain in its purely qualitative, felt,  character. It is then nothing more than a sensory quale. I might even go so far as to abstract from its painfulness.  This quale, precisely as I experience it, is nothing like a distant object that I conceptualize as this or that.

Now the existence of this rock-bottom sensory datum is indubitable and refutes the eliminativist claim. For this datum is not a product of conceptualization, but is something that is the 'raw material' of conceptualization. The felt pain qua felt is not an object of observation, something external to the observer, but an Erlebnis, something I live-through (er-leben). It is not something outside of me that I subsume under a concept, but a content (Husserl: ein reeller Inhalt) of my consciousness. I live my pain, I don't observe it. It is not a product of conceptualization — in the way a distant light in the sky can be variously conceptualized as a planet, natural satellite, artificial satellite, star, double-star, UFO, etc. — but a matter for conceptualization.

So the answer to Churchland is as follows. There can be no question of re-conceptualizing fundamental sensory data since there was no conceptualization to start with. So I am not begging the question against Churchland when I insist that pains exist: I am not assuming that the "traditional conceptualization" is the correct one. I am denying his presupposition, namely, that there is conceptualization in a case like this.

Most fundamentally, I am questioning the Kantian-Sellarsian presupposition that the data of inner sense are in as much need of categorial interpretation as the data of outer sense. If there is no categorization at this level, then there is no possibility of a re-categorization in neuroscientific
terms. 

What is astonishing about eliminative materialists is that they refuse to take the blatant falsity of their conclusions as showing that they went wrong somewhere in their reasoning.  In the grip of their scientistic assumptions, they deny the very data that any reasonable person would take as a plain refutation of their claims.

Pascal on Materialism

"Atheists should say things that are perfectly clear.  Now it is not perfectly clear that the soul is material." (Krailsheimer, #161, p. 82)  An atheist needn't be a mortalist, and a mortalist needn't be an atheist.  But let that pass.  Although the one does not logically require the other, or the other the one, atheism and mortalism naturally 'go together.'  (McTaggart, for example, was an atheist but an immortalist with, apparently, no breach of logical consistency.)

If it were perfectly clear that that the soul is mortal as the body is mortal, then then why all the wild disagreement among materialists/naturalists/physicalists?  Think of all their different theories.  For example, there are eliminative materialists who rely on the (true) premise that no brain state is intrinsically intentional.  They conclude that there are no mental states given that mental states are intrinsically intentional.  But other materialists reject the (true) premise, maintaining that some brain states are intrinsically intentional, namely, the ones that are identical to mental states.

So here is a deep dispute within the materialist camp.  Identity theorists affirm what eliminativists deny, namely, that there are mental states.  Members of each camp believe that materialism is true, but they contradict each other as to why it is true.  Now if it not clear why materialism is true, then it is hardly clear that it is true.  That, I take it, is Pascal's point.

It is not clear that the soul is material (and thus mortal) and it is not clear that it isn't.  Neither view is ruled out or ruled in by the reason resident in the thinking reeds we are.  So you are free to believe either way.  And you are free to act either way.  If you act and live as if the soul is immortal, then you may come to believe that it is.  (See the 'holy water' passage.)  What's more, if you believe that it is then you will live better in this world if not beyond it.  So why not believe?

Of course, you may be constitutionally incapable of believing.  In that case you have a problem that is better addressed by a psychotherapist than by a philosopher.

Made for Thinking

Blaise Pascal, Pensées, Krailsheimer #620:

Man is obviously made for thinking.  Therein lies all his dignity and his merit; and his whole duty is to think as he ought.  Now the order of thought is to begin with ourselves, and with our author, and our end.

Now what does the world think about?  Never about that, but about dancing, playing the lute, singing, writing verse, tilting at the ring, etc., and fighting, becoming king, without thinking about what it means  to be a king or to be a man. 

The Relevance of Conscious Robots for the Philosophy of Mind

Do you understand lasagne?  Of course you do.  But I understand it better because I know how to make it from ingredients none of which is lasagne.  (If I were to 'make' lasagne by fusing eight squares of lasagne, and you were a philosopher, you would protest that I hadn't made lasagne but had 'presupposed' it.  And you'd be right. That would be like making coffee by pouring eight cups of coffee into a carafe.)

It is tempting to suppose that what we know how to make, we understand.  (He said with a sidelong glance in the direction of Giambattista Vico.)  Let's give into the temptation.  Suppose one day humans create a robot that is really conscious, conscious in the way I believe my wife is conscious.  Whether or not I know that she is, in that tough sense of 'know' that entails being certain, I do not doubt for a second that my wife is a genuine bearer of intentional and non-intentional mental states.  She has feelings just as I do and she thinks about things just as I do, and this is not a matter of ascription on my part as when I ascribe to my chess computer the 'desire' to inflict mate.  Her verbal and non-verbal behavior do not merely simulate, even if exactly, behavior that is expressive of real consciousness; it is behavior that is expressive of real consciousness.

So suppose we have a really conscious robot fabricated to look like a woman, so well fabricated, let us assume, as to fool a gynecologist.    If we know that that conscious being is a robot, we may find it hard to believe that she is really conscious.  But suppose we can convince ourselves that our robot is really conscious and enjoys an 'inner' life just as we do.

What implications would this have for the mind-body problem?  Would the existence of a really conscious robot that we had constructed from non-conscious material parts show that consciousness was a natural phenomenon that arises or emerges from sufficently complicated configurations of wholly material parts?  Would it put paid to substance dualism?  Would it show that there was nothing supernatural about consciousness?  Could one refute substance dualism and the notion that consciousness (including self-consciousness and all spiritual functions) has a higher (non-natural) origin by building a conscious robot?

Many would say 'yes.'  But I say 'no.'

If we make a really conscious robot, if we 'synthesize' consciousness and the unity of consciousness from non-conscious materials, what we have done is to assemble components that form a unified physical thing at which consciousness is manifested.  But this neutral description of what we have done leaves open two possibilities:

1. The one is that consciousness simply comes into existence without cause at that complex configuration of physical components but is in no way caused by or emergent from that complex configuration.  In this case we have not synthesized consciousness from nonconscious materials; we have simply brought together certain material components at which consciousness appears.

2. The other possibility is that consciousness comes into manifestation at the complex configuration of physical componets ab extra, from outside the natural sphere.  A crude theological way of thinking of this would be that a purely spiritual being, God, 'implants' consciousness in sufficiently complex physical systems.

On both (1) and (2), consciousness arises at a certain level of materal complexity, but not from matter.  On (1) it just arises as a matter of brute fact. On (2), consciousness comes from consciousness.  On neither does consciousness have a natural origin.  On (1) consciousness does not originate from anything.  On (2) it has a non-natural origin.

Given these two possibilities, one cannot validly infer that consciousness is a wholly natural phenomenon from the existence of conscious robots.  The existence of conscious robots is logically consistent with (1), with (2), and with the naturalist hypothesis that consciousness is purely natural.

My point could be put as follows.  Even if we succeed in creating machines with (literal) minds, this has no bearing on the mind-body problem.  This is because it leaves open the three possibilities mentioned.  Suppose you are a conscious robot who is thinking about the mind-body problem.  Substance dualism would be an option for you.  You could not validly infer that your mind is not an immaterial substance from the fact that you were created in Palo Alto by robotics engineers.  Same goes with me.  I am not a robot, but a conscious animal who came into the world inter faeces et urinam.  (Actually, if the truth be told, I came into the this vale of tears by Caesarean section; but let's not quibble: you came into it inter faeces et urinam.)  But I cannot validly infer from the fact of my animal origin that my consciousness is a wholly natural function.

Now suppose naturalism is true.  There is still the problem of the unintelligibility of the arisal of consciousness from brain matter, an unintelligibility that Colin McGinn, naturalist and atheist, has rightly insisted on.  This unintelligibility will not be diminished one iota by the arrival of conscious robots should such robots make the scene in the coming years.
