Clearly, RES-2 is a better definition of “mental simulation of” than RES-1. Hurley (2008), however, argued that it won’t do either, since it fails to distinguish ST from its main competitor, i.e., the Theory-Theory (TT), according to which mindreading depends on a body of information about mental states and processes (section 5). The crux of Hurley’s argument is this. Suppose that a token visual image V* resembles a token visual experience V and, in doing so, fulfils one of its functions.
