‘When we see, hear, smell, taste, feel, meditate, or will anything, we know that we do so. … Consciousness … is inseparable from thinking, and essential to it. …’John Locke, Essay Concerning Human Understanding ‘Psycho-analysis … cannot accept the identity of the conscious and the mental. It defines what is mental as processes such as feeling, thinking and … willing. … ’Sigmund Freud, Introductory Lectures on Psycho-analysis.In this paper I shall provide a novel version of a traditional epistemic criterion for (...) distinguishing mental entities from nonmental ones, and defend it from likely sorts of objections. By the phrase ‘criterion of the mental’ I mean a set of conditions which is necessary and sufficient for an entity's being mental. (shrink)

In this paper I argue against the view, defended by some philosophers, that it is part of the meaning of mental that being mental is incompatible with being physical. I call this outlook metalinguistic dualism, and I distinguish it from metaphysical theories of the mind-body relation such as Cartesian dualism. I argue that MLD is mistaken, but I don't try to defend the contrary view that mentalistic terms can be definitionally reduced to nonmental ones. After criticizing arguments by certain philosophers (...) which purport to establish MLD, I formulate a criterion for a phenomenon's being mental. I then show that this criterion is neutral between monistic and dualistic theories of the mind-body relation. Since if MLD were true it should be impossible to construct such a criterion, I conclude that it is false. The significance of my paper is that if I am right then I remove one important type of objection to aposteriori, noneliminative forms of the identity theory of mind, namely that such theories ought to be rejected merely on the basis of semantical considerations about the word mental. Beyond that, I believe that my criterion of mental phenomena correctly captures our intuitions about the nature of the distinction between mental and nonmental phenomena. (shrink)
