 Other reasons have been offered for thinking that FP is an inferior theory when compared to the theories of scientific psychology. It has been argued that the contents of propositional attitudes are necessarily world-relating in a way that requires us to look beyond the bounds of an organism’s skin when assigning contents to such attitudes (Stich 1983). On this analysis, the ways we attribute mental state concepts and contents involves recourse to “similarity conditions” and normative principles of charity that could not possibly feature in a mature science of the mind (Davidson 1984, 1987). On this view, FP involves the ascription of contentful attitudes by employing interpretative methods that are inescapably bound up with norms of rationality. For those persuaded by such arguments, to the extent that FP is properly characterized as a theory at all, it must be regarded as a domestic theory of very limited scope: one that is unfit to predict or explain the behavior of exotic subjects, such as very young children and animals (Stich 1983). If this analysis is correct, it reveals FP to be inherently wedded to an explanatory schema that is incompatible with the demands of serious scientific psychology.
