Kim's Exclusion Argument Revisited

Abstract

Critical examination will be made firstly of the exclusion argument, famously developed by Jaegwon Kim, against nonreductive physicalism, and secondly of the identity solution as suggested by Kim himself for the exclusion problem allegedly prompted by his argument. I will argue that the argument is not so much of a trouble for nonreductive physicalism as Kim claims it to be, and that his purported solution is hardly convincing. For one thing, the principles, of which use are made in the argument, concern events, not properties. That is why the argument does not have a direct force to exclude properties. Second, the identification of mental and physical properties involves the idea that a functional property is to be at the same time a structural property, and, on the other hand, it amounts to a reflexive relation such that one and the same property is to realize itself, both of which ideas make little sense. Plus, a brief consideration will be made of the exclusion problem of how it is possible for mental properties to be causally relevant along with physical properties that always suffice for the effect. It will be suggested that mental properties can be causally relevant only if they are dependent upon physical properties, a suggestion which is based on the property-exclusion principle extracted from the principle of explanatory exclusion formulated by Kim himself.
