Abstract

Externalism in the philosophy of mind has been invoked by some philosophers to argue that content‐bearing mental states can’t serve as the explananda in genuinely causal explanations of behaviour. In this paper, I demonstrate that such arguments presuppose that psychological explanations are theory‐based and that, if this theoretical conception of psychological explanation is replaced by the simulation model, we remove the source of the apparent tension between externalism and caus‐ality and are in a position to understand how appeal to content‐bearing mental states may be causally explanatory.
