In a series of recent papers, Cynthia MacDonald and Graham MacDonald offer a resolution to the twin problems of mental causation and mental causal relevance. They argue that the problem of mental causation is soluble via token monism – mental events are causally efficacious physical events. At the same time, the problem of mental causal relevance is solved by combining this causally efficacious mental property instance with the systematic co-variation between distinct mental properties of the cause and the action-theoretic properties (...) of the effect in question. In this paper we argue that the solution offered by Mac- Donald and MacDonald faces significant difficulties in resolving both of the twin problems of mental causation and mental causal relevance.

This paper is about a puzzle which lies at the heart of contemporary physicalist theories of mind. On the one hand, the original motivation for physicalism was the need to explain the place of mental causation in the physical world. On the other hand, physicalists have recently come to see the explanation of mental causation as one of their major problems. But how can this be? How can it be that physicalist theories still have a problem explaining something which their (...) physicalism was intended to explain in the first place? If physicalism is meant to be an explanation of mental causation, then why should it still face the problem of mental causation? (shrink)

Nonreductivist physicalists are increasingly regarded as unwitting epiphenomenalists, since their refusal to reduce mental traits to physical properties allegedly implies that even if there are mental causes, none of them produces its effects by virtue of its being a type of mental state. I examine and reject a reply to this concern that relies on the idea of ​​"tropes". I take the failure of the tropes-based model of causal relevance to illustrate a confusion at the heart of the notion of (...) causal relevance, a notion that is central to the critique of non-reductive physicalism. I aim to dispel the idea that non-reductive physicalism is committed to epiphenomenalism. (shrink)

Dual-attribute theories are alleged to face a problem with mental causation which commits them to either epiphenomenalism or overdetermination – neither of which is attractive. The problem, however, is predicated on assumptions about psychophysical relations that dual-attribute theorists are not obliged to accept. I explore one way they can solve the problem by rejecting those assumptions.
