 So far we have looked at Davidson’s three premises in support of Anomalous Monism—the interaction, cause-law and anomalism principles. In this section, we examine the conclusion that Davidson draws on the basis of these principles—the token-identity theory of mental events, according to which every causally interacting mental event is token-identical to some physical event. We will look at the derivation and nature of this theory, some questions about its adequacy, as well as the additional thesis that mental properties supervene on physical properties. As we shall see, both the token-identity and supervenience claims turn out to be controversial, in their motivation as well as in their consistency with mental anomalism. One key point to keep in mind at this point is that monism is supposed to be derived from the principles and other assumptions that, taken individually, could be acceptable to positions opposing monism.
