Some properties are causally relevant for a certain effect, others are not. In this paper we describe a problem for our understanding of this notion and then offer a solution in terms of the notion of a program explanation.

This book, based on Jaegwon Kim's 1996 Townsend Lectures, presents the philosopher's current views on a variety of issues in the metaphysics of the mind...

It has been argued that nonreductive physicalism leads to epiphenominalism about mental properties: the view that mental events cannot cause behavioral effects by virtue of their mental properties. Recently, attempts have been made to develop accounts of causal relevance for irreducible properties to show that mental properties need not be epiphenomenal. In this paper, I primarily discuss the account of Frank Jackson and Philip Pettit. I show how it can be developed to meet several obvious objections and to capture our (...) intuitive conception of degrees of causal relevance. However, I argue that the account requires large-scale miraculous coincidence for there to be causally relevant mental properties. I also argue that the same problem arises for two apparently very different accounts of causal relevance. I suggest that this result does not show that these accounts, on appropriate readings, are false. Therefore, I tentatively conclude that we have reason to believe that irreducible mental properties are causally irrelevant. Moreover, given that there is at leastprima facie evidence that mental properties can be causally relevant, my conclusion casts doubt on nonreductive physicalist theories of mental properties.

In this paper I will revisit an argument that I have called “the supervenience argument”; it is sometimes called “the exclusion argument” in the literature. I want to reconsider several aspects of this argument in light of some of the criticisms and comments it has elicited, clarifying some points and offering a slightly reformulated—and improved—version of the argument. My primary aim, however, is to discuss and respond to Ned Block’s edifying and challenging critique of the argument in his “Do Causal (...) Powers Drain Away?”—in particular, his claim that the argument has the consequence that if there is no bottom microphysical level, causal powers will “drain away”, leaving us with no causation anywhere. The supervenience argument was designed to show that on a certain popular and influential view of mentality and its relationship to the physical, mental properties turn out to be epiphenomenal, that is, without causal powers of their own.
