In his recent _The Rediscovery of the Mind_ John Searle tries to destroy cognitive science _and_ preserve a future in which a ``perfect science of the brain'' (1992, p. 235) arrives. I show that Searle can't accomplish both objectives. The ammunition he uses to realise the first stirs up a maelstrom of consciousness so wild it precludes securing the second.

Everyone agrees that consciousness is a very special phenomenon, unique in several ways, but there is scant agreement on just how special it is, and whether or not an explanation of it can be accommodated within normal science. John Searle's view, defended with passion in this book, is highly idiosyncratic: what is special about consciousness is its "subjective ontology," but normal science can accommodate subjective ontology alongside (not within) its otherwise objective ontology. Once we clear away some widespread confusions about (...) what science requires, and dismiss the misbegotten field of cognitive science that has been engendered by those confusions, the subjective ontology of the mind, he claims, will lose its aura of unacceptable mystery.

In my book _The Conscious Mind_ , I deny a number of claims that John Searle finds "obvious", and I make some claims that he finds "absurd". But if the mind/body problem has taught us anything, it is that nothing about consciousness is obvious, and that one person's obvious truth is another person's absurdity. So instead of throwing around this sort of language, it is best to examine the claims themselves and the arguments that I give for them, to see (...) whether Searle says anything of substance that touches them.

_The Chinese room argument_ - John Searle's (1980a) thought experiment and associated (1984) derivation - is one of the best known and widely credited counters to claims of artificial intelligence (AI), i.e., to claims that computers _do_ or at least _can_ (someday might) think. According to Searle's original presentation, the argument is based on two truths: _brains cause minds_ , and _syntax doesn't_ _suffice for semantics_ . Its target, Searle dubs "strong AI": "according to strong AI," according to Searle, "the (...) computer is not merely a tool in the study of the mind, rather the appropriately programmed computer really _is_ a mind in the sense that computers given the right programs can be literally said to _understand_ and have other cognitive states" (1980a, p. 417). Searle contrasts "strong AI" to "weak AI". According to weak AI, according to Searle, computers just. (shrink)

In this article, I examine and criticize John Searle's account of the relation between mind and body. Searle rejects dualism and argues that the traditional mind-body problem has a 'simple solution': mental phenomena are both caused by biological processes in the brain and are themselves features of the brain. More precisely, mental states and events are macro-properties of neurons in much the same way that solidity and liquidity are macro-properties of molecules. However, Searle also maintains that the mental is 'ontologically (...) irreducible' to the physical, a view which follows from his understanding of the status and nature of consciousness. Consciousness is essential to the mind; subjectivity is essential to consciousness; and no purely objective, physical description of consciousness could ever capture or explain its essentially subjective character. None the less, Searle maintains that irreducibility is a 'trivial' result of our 'definitional practices' and is entirely compatible with his theory. I contend that this latter claim is based on an equivocation: Searle's conclusion only seems to follow because he alters and trivializes what philosophers ordinarily mean by 'reduction'. I also maintain that Searle's position is reductionist in the ordinary, nontrivial sense. For this reason, his theory fails to accommodate the subjective character of consciousness and fails to solve the traditional mind-body problem. Finally, I briefly discuss Searle's claim that he is not an epiphenomenalist, and argue that given the assumptions of his view there is no interesting causal role for consciousness in the physical world.

The title of The Rediscovery of the Mind suggests the question "When was the mind lost?" Since most people may not be aware that it ever was lost, we must also then ask "Who lost it?" It was lost, of course, only by philosophers, by certain philosophers. This passed unnoticed by society at large. The "rediscovery" is also likely to pass unnoticed. But has the mind been rediscovered by the same philosophers who "lost" it? Probably not. John Searle is an (...) analytic philosopher, with some of the same notions as the positivists and behaviorists who rejected consciousness and "lost" the mind in the first place, but he also does not sound like the kind of reductionist who would have joined that crowd. His views, indeed, are sensible enough, and some of his insights so important, that it is a shame to find his thought profoundly limited by some of the same mistakes and prejudices that ruined philosophy, and not just philosophy of mind, under the influence of those positivists and behaviorists. There is enough of genuine value in his treatment, that it can easily be taken up and, with relatively slight modification, added to what is of permanent value in the history of philosophy. (shrink)

In his book The rediscovery of the mind John Searle claims that unconscious mental states (1) have first-person "aspectual shape", but (2) that their ontology is purely third-person. He attempts to eliminate the obvious inconsistency by arguing that the aspectual shape of unconscious mental states consists in their ability to cause conscious first-person states. However, I show that this attempted solution fails insofar as it covertly acknowledges that unconscious states lack the aspectual shape required for them to play a role (...) in psychological explanation.
