Abstract

A general characterization of functionalist theories of mind is offered and a number of issues are discussed which allow for alternative versions of functionalism. Some issues, such as the distinction between the implicit definition and partial specification views are of a general nature, while others raise questions more specific to functionalism, such as whether the relation between psychological and physiological properties is one of identity or instantiation. Section II attempts to undermine several arguments which have been offered to support the non-identity position. In the final section, the suggestions that the relevant notions of functional equivalence might be unpacked solely in terms of abstract automata features or entirely in terms of causal relations to nonintentionally characterized behavior are shown to be inadequate.
