The relation between subjective consciousness and the physical brain is widely regarded as the last mystery facing science. Papineau argues that consciousness seems mysterious not because of any hidden essence, but only because we think about it in a special way. He exposes the resulting potential for confusion, and shows that much scientific study of consciousness is misconceived.

(I) John Searle's conception of consciousness in the 'Mind the Gap' issue of the Journal of Consciousness Studies remains short on content, no advance on either materialism or traditional dualism. Still, it is sufficiently contentful to be self-contradictory. And so his Biological Subjectivity on Two Levels, like materialism and dualism, needs replacing by a radically different conception of consciousness -- such as Consciousness as Existence. (II) From his idea that we can discover 'gaps', seeming absences of causal circumstances, in our experience of deciding and acting, Searle is led to the positing of a self and to mysterious causing. (III) In fact philosophers of determinism and freedom over three centuries have concerned themselves with what are now termed 'gaps'. Searle's advance is a useful terminological one. Compatibilist philosophers of freedom, contrary to what is said, have not missed any point at all. A successor to both Compatibilism and Incompatibilism is needed. (IV) Searle's previous account of deciding and acting in Biological Subjectivity on Two Levels does indeed fail because of its epiphenomenalism. (V) The culmination of his paper, his preferred hypothesis now about deciding and acting, is that down-up causation is true of it but not left-right causation. Quantum Theory as often interpreted doesn't work down-up but does work left-right. The hypothesis is entirely in the tradition of the Incompatibilist and Libertarian philosophers of determinism and freedom, whom Searle has joined, but is factually incredible.

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 begins his recent article “Dualism Revisited” by stating his belief that the philosophical problem of consciousness has a scientific solution. He then claims to refute dualism. It is therefore appropriate to examine his arguments against dualism from a scientific perspective.

Searle suggests biological naturalism as a solution to the mind-brain problem that escapes traditional terminology with its seductive pull towards either dualism or materialism. We reconstruct Searle's argument and demonstrate that it needs additional support to represent a position truly located between dualism and materialism. The aim of our paper is to provide such an additional argument. We introduce the concept of "autoepistemic limitation" that describes our principal inability to directly experience our own brain as a brain from the first-person perspective. The neglect of the autoepistemic limitation leads to inferences from epistemic properties to ontological features - we call this "epistemic-ontological inference." Searle attempts to avoid such epistemic-ontological inference but does not provide a sufficient argument. Once the autoepistemic limitation is considered, epistemic-ontological inference can be avoided. As a consequence, one can escape traditional terminology with its seductive pull towards either dualism or materialism.
