Eliminative materialism



[Update here:  http://worldofdrjustice.blogspot.com/2014/04/eliminative-materialism-expanded-update.html ]

…those bright and breezy Americans  who call themselves Behaviourists.  They declare with some warmth that there is really nothing in their minds, and that they only think with their muscles.
-- G.K. Chesterton,  Robert Louis Stevenson (1927)

Biology is only the Fascist substitute for sociology.
-- Arthur Koestler, Scum of the Earth (1940)

Maxfield Parrish:  Cadmus
We did not have to wait for the tribe of those laboratory nihilists known as neuroscientists, to behold an academic school dedicated to reducing free will and cogitation to the level of meat.  The behaviorists were there first.    And it is our great good fortune that we are spared the chore of actually reading and refuting their earlier and generally gratingly ill-written output, since their fifteen minutes have expired(*), the quietus marked by a famous and scathing review of B. F. Skinner’s Verbal Behavior, by Noam Chomsky, way back in 1959 (a good year -- aye, a vintage year).
 
Skinner himself, and others of his spawn, continued to “engage in writing behavior”.(**)   And like the dragon’s-teeth of Cadmus, the doctrine springs up ever anew, in this or that contorted form.





[(*)  I spoke too soon.  Savor my groveling retraction here.]

[(**)  The phrase was made famous by a journalist who, to test the nature of asylum-based therapy in general  and involuntary commitment in particular, had himself commited, and immediately began acting perfectly normal, and telling the doctors he’d like to go home.  He kept a journal of his experiences.   This latter fact did not go unnoticed by the keenly observant psychiatric nurses, who wrote in his chart, “Patient engages in writing behavior.”  An immortal and dactylic line.]

Skinner, apart from his paid occupation of making life miserable for rats, is best known as the author of Beyond Freedom and Dignity (1971 -- not such a good year).  The title echoes that of Jenseits von Gut und Böse,  by that other evil troll, Nietzsche:   beyond, not in the sense of uplift, but of, “Get O-o-o-vah-rit!” -- A similar bit of titular legerdemain (sugar-coated in the title, rat poison on the inside) was perpetrated by Patricia Churchland, in Neurophilosophy: Toward a Unified Science of the Mind/Brain (1986).  What is really being proposed there is not Unity, but Anschluss, with the mind playing the hapless role of Austria.


Professor Skinner, hard at work in the lab

Again, prior to contemporary neuroscientists, there were philosophers who ground much the same axe.   Wikipedia (s.v. “Self-refuting idea”), re eliminative materialism, speaks of identity theorists like the philosophers Boring and Smart, who “claim that ideas exist materially as patterns of neural structure and activity.”  Now, that is one unilluminating and bone-headed idea.  By which I mean, of course, no more than that it is an unilluminating and bone-headed pattern of neural structure and activity.  Owing possibly to an excess of calcium at one of the synapses.

And why, indeed, stop short at the level of the cells, themselves already doubtless epiphenomenal?  Take it right down to quantum mechanics!   Let some gaggle of labcoats come up with the Schrödinger equation for the Bible, and another for “Paradise Lost”, and show us how certain passages -- excuse us, certain Hermitian forms -- of the former, lead directly to the eigenkets of the latter.  Put literary critics  plumb out of work.
(Something more than just a joke:  Cf. entomologist/ultrareductionist Edward Wilson donning the robe of a Milton scholar here.)

-- A further word about this scenario of ideas as “patterns of neural structures and activity".  It really is little more than ye olde idea of Ideas as Pictures-in-the-head, but dressed up in a modern labcoat (the sort worn by actors playing doctors on TV); and this is one subterranean source of  plausibility of a doctrine that  on logical (and indeed theological) grounds  is a tissue of absurdity.

~

What gives the “thought is a physical pattern” account some specious plausibility, is our modern picture of vision:  which, to be sure, is vastly more complex than the everyman’s pre-theoretical account, whereby the vision of an apple is like a little apple in my eye.  (Compare, indeed, the etymology of the word pupil.)  -- Actually, the completely pre-theoretical account doesn’t even involve vision at all;  it’s just, “Behold! an apple!”  (or, holophrastically:  Gavagai!)

In that account, we begin with the beheld object.  
  (a)  It is, as a ding-an-sich, as hopelessly unknowable in its totality as a black hole;  yet like those reticent celestial bodies -- the veiled houris of the stellar harem -- by their corona ye may know them (that, and a bit of math).
  (b)  From this object -- let us take it to be specifically a coffee-cup, since we have proved the existence of these -- photons and phonons and perhaps even an occasional Higgs boson, bounce and boing and go-or-do-not-go through visual slits, in some inextricable and inexplicable quantum fashion, to wind up
  (c ) landing on, and lighting up, this or that spot on the retina.  From there,
  (d) ganglia shiver and synapses thrill, and eventually
  (e) the visual cortex receives various rude jolts, after which
  (f) the rest of the brain somehow sorts it all out, until finally
  (g) the mind says, “Aha!  There it is!  Time for a spot of java!”

Unfortunately, this comparatively simple scenario won’t do for the generality of ideation.  It would seem that, when these reductionist gentlemen contemplate an “Idea”, they go no farther than an analogue of (f) or at best (g), for an object of thought as simple as a coffee-cup (or, in their own case, their own endlessly contemplated navel) -- the ‘idea’ of one, rather than the image of one.  -- One is reminded of Hadamard’s plaint, in The Psychology of Mathematical Invention, that previous researchers into thought-processes had restricted themselves to the elementary thumb-sucking mental-motions of the Beoetians, which simply do not display the richness of thought-processes of research mathematicians, so that his own researches had to start from scratch.
(Similarly, generative linguistics would not have gotten far, had it never considered sentences more complex than "John is fat.")

For consider:
What the cognitive eliminativists are proposing, is not that a thought consists of some pattern of little electrochemical twitches and irritations plus ideation (the thinker contemplating the canvas of his own neuroprocesses, as it were);  their explicandum cannot involve the explicans.  No, it is really just -- splat -- that.

Now consider the following ideas:
  (a)  A topological space T is regular.
  (b)  T has a countable basis for its topology.
To each of these corresponds -- in Henry’s head -- a cortical panorama (A, B) not unlike a TV test-pattern plus static, or a Jackson Pollock painting on a bad day.

And consider that, as we all know by now, (a) and (b) imply
  (c)  T is metrizable.
which in turn duly corresponds to some porridge of pixels (C) on Henry's cortex.  Fine, we grant that.
But how  by all that is holy  do (A) and (B) imply (C)?  The moreso as Henry’s cortical idiosyncrasies  differ from those of Hector (A’, B’,C’), let alone those of the silicon-based mathematicians of the planet Gnorf:  who, whatever their physiological differences from ourselves, must reach exactly the same conclusion as did Urysohn, since that conclusion is, in fact, a fact (laid up in heaven, where Churchlands do not penetrate, and the worm corrupts it not)

~     ~      ~

Ethicists should likewise soon be out of a job.  The latest in the public press:

The End of Evil?
Neuroscientists suggest there is no such thing.
Are they right? 


A word:  I have no quarrel at all with the reductionist program as propounded and practiced by, say, Steven Weinberg (who embraces the term).  The problem comes in with the eliminativists who do not really mean to explain things, but to explain them away.

What tends to get eliminated, in these proceedings, are things like consciousness and free will -- features of which we had grown rather fond.   Their very familiarity (as “folk theory”), for these gentlemen,  somehow tells against them.  As though a good rule of thumb were, If the ancient Greeks believed it, it must be wrong.  An eternal verity gets rechristened a “stagnant theory”. 

(Extraordinary idea, that, in any case: that to be any good, a theory must, like a fashion-slut, annually change the length of her skirts.  By that measure, the truths of numbers known to Diaphantos must be positively mildewed.)
Here  phlogiston plays ever and again the useful role of whipping-boy.  (Indeed, given the continued prominence of this ethereal etwas in philosophical debate, it must count as one of the most fruitful scientific hypotheses ever.  If it didn’t not-exist, someone would have to uninvent it.)  

The line of reasoning, reduced to its essentials, runs:  Well if that thing turned out not to exist, maybe freedom and God and all that lot   are just illusions too.


One problem with this angle of attack is that there's more to physics than phlogiston.  Also on the roster of theoretic posits  we find:  acceleration, force, electromagnetism, atoms, protons …  Phlogiston went out on a limb, which broke;  atoms & co. went out on a limb, and so far it seems to have held.   The eliminativists are being rather choosy in what to highlight.

Another problem with their reasoning  is that it’s nonsense.   Shooting down this or that hypothesis of theoretical physics, or even the whole lot of them, is not at all the same thing as denying what every mother has been telling her children since the beginning of time.   We are rather more certain of our own consciousness and free will, than we are of protons.

Let us examine another favorite butt of their mirthless hilarity.  Your great-great-grandsires believed in God, and that the sun set in the west.  The more fools they!   We New Atheists proclaim triumphantly that the earth circles the sun, and not the other way about.  Therefore, everything else you believe is false as well.
But in point of fact, you haven’t got much further along by taking the sun as the rest-point of your dynamical system, than when you stood firm on the earth.  For now you may be held to depict a system in which the entire galaxy whirls lumbrously around the axis of a single, peripheral, faint star.
In reality, none of these choices of a reference frame intend the absurdities ascribed to them.   Each has its use for some purpose or other.  Grandpa was well within his rights, both cosmologically and theologically.

All biochemists and molecular biologists today are ‘mechanical materialists’.
J. Maynard Smith & E. Szathmáry, The Origins of Life (1999), p. 11

Probably no harm in that, so long as the molecularists  stick to their last, and don't go sounding off in the Sunday supplements about matters that concern them not;  indeed, it would be more concerning, were they all Cantorian Realists, or Presbyterians.   But the day when all musicologists, or mathematicians, or literary critics, take mechanical materialism for their lodestar and touchstone, is the day when we shall cease to learn anything of interest about music, math, or literature.

We earlier glanced at the program of consilience, which (speaking somewhat informally) depicts the sciences stacking up one atop the other, like proverbial pancakes, while the life-giving maple syrup of shared method and ontology, seeping from one to the next, unites them.   (That summary, while not perfect, is both more concise and somewhat clearer than what you may glean from scattered passages in Wilson’s book.)  Eliminative materialism takes all this a step further:  the whole stack is squashed flatter than flat (again, the individual pancake has passed into legend for this very quality) into an inedible paste: the which, however, is declared to be the sole reality, things like syrup and pats of butter being just figments of your imagination (which itself does not exist).  Understandably, this philosophy was quite popular among the guards at Belsen-Belsen.

That may sound harsh, but truly, the often creepy frisson of the behaviorist/neuroscientific mindset does recall certain experiments during that unlamented Reich which were better left undone.  Steven Pinker, The Blank Slate, p. 19, on the founder of American Behaviorism:

Watson presented a baby with a white rat, and then clanged a hammer against an iron bar, alledgedly making the baby associate fear with fur.

Thus, to all our weightier indictments against Nominalism in all its forms, we add this slogan:   
Behaviorists Hate Bunnies.”
(Our own favorite behaviorist, jolly Dr. Quine, does suffer from a certain lagomorphobia,  in his obsession with "undetached rabbit parts", documented here.)



Wilson pens a highly entertaining parable of the termite ethical code, extoling:

…the deep, saprophytic, basidiomycetic penetralia of the soil …. the sanctity of the physiological caste system; the evil of personal rights (the colony is ALL!); … the aesthetic pleasure of eating feces from nestmates’ anuses  after the shedding of our skins; and the ecstasy of cannibialism … (it is more blessed to be eaten than to eat).
Edward O. Wilson, Consilience (1998), p.  148

This is jolly stuff, skillfully done; probably give Donald Trump an erection.  Yet one senses a sour note, as the (“consilient”) goal of the eliminative materialists   is to provide a similar account of human morality, decency, caring, flights of fancy, love …. Ever again and inevitably, these proctoscopists return to the anus, the central life-ring of their Weltanschauung.

~     ~      ~


To be fair to the reductionist program, let us briefly consider a proposal narrated by Wilson, who is both a much more graceful writer  and a more congenial companion than Skinner or the Churchlands.

Wilson offers one worked-out example of  basically eliminative reduction (or ‘consilient’ explanation): from oneirology straight down to biochemistry.  Here is a sketch of the bad old days of Freud:

Mysticism and science meet in dreams.  … When we sleep, the ego releases its grip on the id…  Freud … -- to put it as kindly as possible -- guessed wrong.
Edward O. Wilson, Consilience (1998), p. 74

Wilson is in fact a kind and temperate man; that mild rebuke is as strongly-worded as anything in the book.  (He is even able to discuss the Postmodernists without resorting to scatological invective, a task far beyond my own capacities.)

But now (p. 75) for the good news:

The competing and more modern hypothesis of the basic nature of dreaming  is the activation-synthesis model of biology.  … Sleep descends upon the brain when chemical nerve cell transmitters … such as norepinephrine and serotonin, decline in amount… Simultaneously a transmitter of a second kind, acetylcholine, rises in amount.  …

Etc., etc.; we skip to the exciting climax on the next page:

The electrical membrane activity, still mediated by acetylcholine at the nerve junctions, moves from the pons (the P of PGO), a bulbous mass of nerve centers located at the top of the brain stem, upward to the lower center of the brain mass, where it enteres the geniculate nuclei (G) of the thalamus, which are major switching centers in the visual neuronal pathways.  The PGO waves then pass on to the occipital cortex (O), at the rear of the brain, where integration of visual information takes place.

Voilà ! Any questions?  No?  We're done then.

Oh dear -- did I type all that up aright?  Was it not perhaps the serotonin that flows into the thingummy, thereby (de)activating the thalamo-geniculo-pataphysico reaction?  Well, no matter;  for you will notice that we have so far learned absolutely nothing about actual dreams.(*)

(*  Don’t misunderstand:  this is sound, painstaking work, and it is excellent that someone is doing it.  No doubt it will prove crucial to some hyperspecialists in the approriate microcompartment of biochemistry.  For the general man of science and letters, on the other hand, it is precisely as fascinating as the mysteries of the pancreas.)

This lacuna Wilson hastens to remedy by rushing in with his own broad-brush description, eclipsing that of that bungler Freud:

We fly through the air, swim in the deep sea, walk on a distant planet, converse with a long-dead parent … In dreams we are insane.  We wander across our limitless dreamscapes as madmen.

Hm.   Doesn’t ring a bell, either with my own experience or that of friends with whom I have discussed such things.    In my own dreams, I tend to be at work, or in a classroom, or (oddly) at some sprawling party on the grounds of a great country house.   No flying through the air;  more like, irksome difficulties catching the right bus.  But let that pass.   No doubt spending your days as a reductionist  means you must compensate with florid fantasies at night.
But the real killer is that last line.   It is, I believe, wildly and crucially false.   The real mind-set of the typical dreamer was captured perfectly by Louis Carroll:  Alice retains her level-headedness, while all around her are acting fantastically, and she rather taxes them for their behavior.  (A similar depiction occurs in the long-running comic strip, "The Strange World of Mr Mum".  The eponymous everyman wanders bemused through the strangest situations.)  In our dreams we remain our real selves:  we retain, in particular, our unbanishable morality, not doing in dreams what we would not do or at least fantasize doing in waking life. (Morality: a word anathema to some of these gentlemen -- though here Wilson himself is sound enough -- yet it survives the oneiric lysis, as it shall survive their nihilism.)  We remain perfectly rational, only…. just not at our best.   For instance, in dreams I often work out etymologies, or expound mathematical ideas.  These are without exception in error -- hey, happens to the best of us -- but that is what I do, I don’t imagine I’m a prophet, or a giant cockroach, or that everyone is out to get me, or what not.

Freud may not have nailed it, but you’ll learn more about actual dreaming from Die Traumdeutung than from this ultrareductionist stuff.

[Update]  I am currently re-reading Die Traumdeutung;  some actual reflections might follow.

That only somewhat facetious polemic brings me to another point.   While specialists of this or that stripe  may want to drill down to the last detail, what most of us require -- expressing this somewhat provocatively -- is an explanation that is as shallow as possible, in that it digs down only as far as it needs to, to clear things up a bit.  (Compare Quine's "Maxim of shallow analysis:  Where it doesn't itch, don't scratch.")  And even if you wind up doing a deep-dive yourself, what you intellectually retain is likely to be an explanatory skeleton. 
Thus, take mathematics.  When a proof is truly “irreducibly reductionist” (to coin a phrase), like that of the Four-Color Theorem,  where intermediate guiding Ideas, of general application, do not emerge, but everything is tediously and computationally broken down into a bad-infinity of special cases, mathematicians are disappointed and frustrated.   What we want ultimately is an agencement of Leading Ideas.  We might dutifully check the details of the proof, but these we shall probably not retain.
(Keynes, whose Treatise on Probability  brims with Leading Ideas, charmingly prefaces one particularly symbol-ridden chapter with absolution for any reader who wishes to skip it.  “We do it, to show that the thing can be done;  the exercise is more for the benefit of the writer, than the reader.” [Quoting from memory, so you might not be able to Google that.])

So, suppose we wish to know what launches birds or butterflies on their migrations.  What we hope to hear about is an account in terms of concepts antecedently familiar or at least learnable without too much fuss -- things like average temperature, extremal (trigger) temperature, average length of daylight, or depletion of ambient foliage.  Or, how do they find their way.   We are prepared for an explanation in terms of magnetism, starlight, or even “an instinct, varying in its details from species to species, whose guiding factors are as yet unknown”.   In the first-named case, we are open to talk about iron molecules in the inner ear;  but if the account in inextricably entangled in the details of the cross-effects between the ornithoboson cycle and the L-dextro-retro-feniculation mechanism, it’s TMI, and we tune out.  A ‘molar’ elucidation suffices for the general public and for the general zoologist   (and indeed, even this much is often too much to ask in practice;  apparently major mysteries remain about many migration-patterns, including the celebrated case of the Monarch butterfly).  An avian histologist might want to know more about those iron particles and their interaction with the inner ear.  But at some point even he is satified to call it a day, content to say, of levels yet further down, The Thing Can Be Done.

And sharks (a segment this morning on NPR).

Now, sometimes, perhaps usually, no such shallow-draught explanation will be forthcoming.  Thus, the saga of individual animals gets you only so far towards the understanding the appearance and disappearance of species; a lower-level unit, the gene, turns out to be quite handy; and to further understand the behavior of these, we occasionally have to get down among the DNA.
Consider further,  the symmetries of snowflakes.  The usual explanation is straightforwardly intuitive, local and deterministic.  But somehow I don’t buy it.   It just feels as though such endlessly varied detail, with symmetries nonetheless rigidly enforced, brewed in a whirling cauldron of stochastic accident, must have some energy-minimizing post-editing -- something global (or “holistic”, if you like that word) along the lines of surface tension, or of standing waves on tympani.  In which case you’ll be dragging in Bessel functions, or calculus of  variations, or quantum mechanics.   And in that case  snowflakes will be one of those phenomena that can barely be intuitively understood.  In this, it would join ranks with what may be a host of questions that Homo sapiens will never really understand.  -- This is the Mysterian stance.  Believe it or not, this is also the orthodox Judeo-Christian-Muslim position towards the ultimate unknowability of the mind of God -- certain TV preachers and football coaches to the contrary.

So:  Reduce as you can and as you must, but not for its own sake.  Practically, cognitively, there is a price to pay.   The naturalist tracking an ecosystem knows he may need to have recourse to natural selection, perhaps to geology, a bit of statistics -- but it’s not as though he can’t wait to get his hand on the string theory of the thing. 
Or consider the case of generative syntax, which over the years has dug ever deeper, and become increasingly abstract in its ontology of explanation, drifting further and further from categories familiar to Jespersen.  Yet it did this, not out of any fetishism for abstraction, nor reductionism for its own sake, but rather because earlier, more traditional and intuitive attempts just did not work.  Indeed, the principle figure behind this sweep of developments has also consistently been in the forefront of debunking popular but vacuous styles of reductionism.

~     ~      ~

Again, to be fair, let us quote a man whose mind we entirely admire, whose prose sparkles like dew-bedecked blooms at break of dawn.  None other than -- but you have already guessed -- the master himself, Mr. Willard (“Van”) Orman Quine:

Corresponding to every mental state … the dualist is bound to admit the existence of a bodily state  that obtains when and only when the mental one obtains..  The bodily state is trivially specifiable in the dualist’s own terms, simply as the state of accompanying a mind that is in that mental state.  Instead of ascribing the one state to the mind, then, we may equivalently ascribe the other to the body.  The mind goes by the board, and will not be missed.(*)

(*In fairness to Quine, let us hasten to add, that his core concern here is quite abstractly ontological, even quantificational, as befits a symbolic logician.   It may even be compared to the notion, not of dualism, but of duality, in mathematics, being related rather like the positive and the negative of a photograph, where either one will do.  --  Still, his chosen periscopic viewpoint leads to some no very edifying reflections: “Mental states, construed as states of nerves, are like diseases.”  And such reasonings spawned venomous afterbirths  with Dennett and the Churchlands.)

This nifty epiphany casts our Quine into something of a Little-Jack-Horner state (= excitation of synapse #5328b), for (coming to his senses) he straightly confesses that “this effortless physicalism smacks of trickery”.   Yet what he says is true enough. --  True… enough, for sake of argument; that no such isometric reduction has ever actually been made and perhaps never will, is beside the present point.  Let us grandly grant it done;  Nobels all round, lads!  What then?  Well, then, nothing.  We are back where we were.

For: every carpet has an underside.  We may even concede (perhaps over-generously) that both sides are interderivable:  given the one, you can work out the other.  Now, you and I prefer the upper side, where green birds are depicted in an azure sky, and the prince urges his huntsmen  forward in the chase.  Equally -- and it is their right, -- the proctoscopic philosophers prefer to ogle the underside, an unintuitive tangle of knots and loose ends.  You and I can observe why the green beings  appear on a background of blue;  whereas the proctoscopists can only stare miserably at their welter of circumanal shorthairs.

Such, indeed, is the case most favorable to the proctoscopists, where we are concerned only with a single static pattern.  Consider now -- well, our old friend, the Urysohn Metrization Theorem.  All the proctoscopists can do, in trying to wrangle with that, is to examine the brains (not, note:  the thought processes) of actual people trying to wrangle with it, since the theorem itself is incorporeal.  (Compare the Competence:Performance  distinction, in linguistics. Recall as well the unprofitability of obsession with the latter.)  And granting our epistemological vivisectionists  superhuman abilities  far beyond the offing of likelihood, they will be able to peer into everybody's brain-pan  and inspect the various chemical blurps, electric fizz, and meandering fat-globules  of the would-be topologists.  Yet worse, far worse for their case -- even granted their ability to somehow read off, from this mephitic brew, such messages as “SMITH - NOW - CONSIDERING - FIRST-COUNTABILITY.  UH-OH, SMITH SAD.   MEBBE FIRST-COUNTABILITY NOT ENOUGH. OH NOES!!”, -- they will be not a whit closer to understanding the theorem.  For their data-set consists of all the various blunderers of the earth, barging about, running into dead-ends, committing fallacies, thinking they’ve proved it whereas in reality (victims of a misfolded protein) they did not -- really one would like to see Monty Python work this one up into a skit.  (They did the complete works of Marcel Proust;  why not Urysohn?)  For the truth of the theorem resides, not in the cloaca which these gentlemen are pleasured to inspect, but in the realm of Invisibilia, the kingdom of the Lord of Hosts.  And the valid mathematical moves made by this or that fallible incarnated creature, in their groping attempts to approach the truth, gain their validity, not from thermodynamic or statistical considerations, but from our miraculous harmony with such abstract truth itself, which stems, we know not whence;  though some of us have an inkling.

That, technically, one might perform such fundamental (or rather fundament-level) analyses or rather catalyses,  shows only that it is possible, by the wrong sort of reduction, to reduce meaningful phenomena to the meaningless.  We may dub this excretory reduction, as opposed to explanatory reduction.  And the craft practiced by these proctoscopic coprophiles, we may dub stercochemistry.  (Not a typo, that:  sterco-, not stereo-.)  Indeed, in this perspective, we notice that the doctrine of -- eliminative materialism, is singularly well-named.
