As part of his ongoing critique of metaphysical realism, Hilary Putnam has recently argued that current materialist theories of mind that locate mental phenomena in the brain can make no sense of the proposed identifications of mental states with physical (or physical cum computational) states, or of the supervenience of mental properties with physical properties. The aim of this paper is to undermine Putnam's objections and reassert the intelligibility – and perhaps the plausibility – of some form of mind-body identity and supervenience.

The aim of this paper is to defend the causal homogeneity of functional, mental properties against Kim’s attack. It is argued that (a) token identity is sufficient for mental causation, that (b) token identity implies a sort of functional reduction, but that (c) nonetheless functional, mental properties can be causally homogeneous despite being multiply realizable: multiple composition is sufficient for multiple realizability, but multiple composition does not prevent the realizers from having their pertinent effects in common. Thus, the causal exclusion problem provides no argument for abandoning the position that there are functional, mental properties that are natural kind properties.

That there is an epistemological difference between the mental and the physical is well- known. Introspection readily generates knowledge of one’s own conscious experience, but fails to yield evidence for the existence of anything physical. Conversely, empirical investigation delivers knowledge of physical properties, but neither finds nor requires us to posit conscious experience. In recent decades, a series of neo-Cartesian arguments have emerged that rest on this epistemological difference and purport to demonstrate that mind-brain identity is false and that consciousness is not even realized by or supervenient on physical properties. Where Descartes argued he could clearly and distinctly conceive mind and body as existing separately, contemporary anti-physicalists hold that the conceivability of worlds in which actual world correlations between physical and phenomenological properties fail shows that these correlations are contingent rather than logically or metaphysically necessary. Together with Descartes, they conclude from conceivability that identity, as well as strong supervenience, is false.¹ If the argument of this paper is correct, however, then there is an argument for dualism that arises from the epistemological distinction, is grounded in the Meditations, and is yet distinct from the

conceivability arguments pursued both by Descartes and contemporary anti-physicalists. Furthermore, the argument is immune to the standard objections to conceivability arguments: its conclusion follows even if there are a posteriori identities between physical and phenomenal properties.

Scientific essentialism is the view that some necessities (e.g., water = H2O) can be known only with the aid of empirical science. The thesis of the paper is that scientific essentialism does not extend to the central questions of philosophy and that these questions can be answered a priori. The argument is that the evidence required for the defense of scientific essentialism (e.g., twin earth intuitions) is reliable only if the intuitions required by philosophy to answer its central questions is also reliable. Included is an outline of a modal reliabilist theory of basic evidence and a concept-possession account of the reliability of a priori intuition.

Argument for Epiphenomenalism [I]: (A) Mental event-tokens are identical with physical event-tokens. (B) The causal powers of a physical event are determined only by its physical properties; and (C) mental properties are not reducible to physical properties.
