Karen Bennett has recently articulated and defended a “compatibilist” solution to the causal exclusion problem. Bennett’s solution works by rejecting the exclusion principle on the grounds that even though physical realizers are distinct from the mental states or properties that they realize, they necessarily co-occur such that they fail to satisfy standard accounts of causal over-determination. This is the case, Bennett argues, because the causal background conditions for core realizers being sufficient causes of their effects are identical to the “surround” (...) conditions with which the core realizers are metaphysically sufficient the states or properties that they realize. Here we demonstrate that the background conditions for the causal sufficiency of core realizers for their effects are not identical to the core realizer’s surrounds, nor do backgrounds necessitate such surround conditions. If compatibilist solutions to exclusion can be defended, a different argument will be needed. (shrink)

Abstract: I offer a novel objection to Jaegwon Kim's Supervenience Argument. I argue that the Supervenience Argument relies upon an untenable conception of the base physical properties upon which mental properties are supposed to supervene: the base properties are required to be both ordinary physical/causal properties and also unconditionally sufficient for the properties that they subvene. But these requirements are mutually exclusive; as a result, at least two premises in the Supervenience Argument are false. I argue that this has disruptive (...) consequences both for the reductive position that Kim defends and the non-reductive position that he attacks. Neither side in the debate over the status of functionally conceived mental properties comes out unscathed. (shrink)

In this paper I discuss the kinds of dependence relation that philosophers have argued may obtain between neural events and conscious events; between Ns and Cs. Three major candidate relations are constitution, realization, and identity. There are other candidates for the mind/body relation, but these will serve as the major options. Indeed, these are already more than three options, because philosophers do not agree on the best way to understand constitution; still less to understand realization. I argue that dispute is (...) not merely "metaphysical": each candidate has distinct empirical consequences. (shrink)

The realization relation is commonly explicated via, or identified with, the causal role playing relation. However, the realization relation does not formally match the causal role playing relation. While realization is a relation between a base realizer property and a single higher level realized property, I argue that the causal role playing relation as typically defined is a relation between a base property and two higher-level role properties. Advocates of using causal role playing to explicate realization must therefore decide which (...) of the two kinds of role property they identify with realized properties; I argue that neither choice is good, and the fact that one must make a choice is worse. A search for a new way of defining realization is in order. (shrink)
