What, in essence, characterizes the mind? According to Searle, the potential to be conscious provides the only definitive criterion. Thus, conscious states are unquestionably "mental"; "shallow unconscious" states are also "mental" by virtue of their capacity to be conscious (at least in principle); but there are no "deep unconscious mental states" - i.e. those rules and procedures without access to consciousness, inferred by cognitive science to characterize the operations of the unconscious mind are not mental at all. Indeed, according to Searle, they have no ontological status - they are simply ways of describing some interesting facets of purely physiological phenomena.

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.

John Searle's The Rediscovery of the Min is a sustained attempt to locate the mind and the mental firmly in the realm of the physical. Consciousness ,claims Searle, is just an ordinary biological feature of the world ... More specifically,``[t]he mental state of consciousness is just an ordinary biological, that is, physical featureof the brain''. Searle is adamant: ``Consciousness,to repeat, is a natural biological phenomenon''.

In my article I evaluate Searle's account of mental causation, in particular his account of the causal efficacy of unconscious intentional states. I argue that top-down causation and overdetermination are unsolved problems in Searle's philosophy of mind, despite his assurances to the contrary. I also argue that there are conflicting claims involved in his account of mental causation and his account of the unconscious. As a result, it becomes impossible to understand how unconscious intentional states can be causally efficacious. My conclusion will be that if Searle's conception of unconscious intentionality is to play a genuine role in the causal explanation of human action, it needs to be rethought.

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.

"The philosophy of mind is unique among contemporary philosophical subjects," writes John Searle, "in that all of the most famous and influential theories are false." In Mind, Searle dismantles these famous and influential theories as he presents a vividly written, comprehensive introduction to the mind. Here readers will find one of the world's most eminent thinkers shedding light on the central concern of modern philosophy. Searle begins with a look at the twelve problems of philosophy of mind--which he calls "Descartes and Other Disasters"--problems which he returns to throughout the volume, as he illuminates such topics as the freedom of the will, the actual operation of mental causation, the nature and functioning of the unconscious, the analysis of perception, and the concept of the self. One of the key chapters is on the mind-body problem, which Searle analyzes brilliantly. He argues that all forms of consciousness--from feeling thirsty to wondering how to translate Mallarme--are caused by the behavior of neurons and are realized in the brain system, which is itself composed of neurons. But this does not mean that consciousness is nothing but neuronal behavior. The main point of having the concept of consciousness, Searle points out, is to capture the first person subjective features of the phenomenon and this point is lost if we redefine consciousness in third person objective terms. Described as a "dragonslayer by temperament," John Searle offers here a refreshingly direct and open discussion of philosophy, one that skewers accepted wisdom even as it offers striking new insights into the nature of consciousness and the mind.
