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.

[opening paragraph]: Nicholas Humphrey's ambitiously titled paper falls into two main parts. In the first, he offers a diagnosis of the current state of the mind-body debate and a general prescription for how to go about seeking its solution. In the second, he aims to fill that prescription with a specific proposal that he regards as bringing us much closer to a resolution of the underlying problem. Though I will take issue below with a few important details, I largely agree with his diagnosis of the current debate. However, I remain sceptical about just how far his more specific suggestions can take us toward an adequate understanding of the brain-consciousness relation. Perhaps with more development, they might cut deeper to the core, but in present form they seem subject to the same sorts of objections that Humphrey himself raises against other prior proposals, for example, absent qualia challenges

Functionalism, in one form or another, is probably at present the most commonly held position concerning the nature of mental states among philosophers. Functionalists all accept the basic thesis that mental kinds are functional kinds, and that what makes a mental item an item of a given mental type is the functional role it plays within a relevantly organized system. This chapter considers arguments meant to show that various forms of functionalism are unable to accommodate or explain some of the real features of qualia, as well as functionalist replies to those arguments. The traditional idea of qualia is closely linked with the classic representational theory of perception. The most influential qualia‐based anti‐functionalist arguments rely on intuitions about certain imaginary cases or thought experiments, especially those involving so‐called “inverted qualia” and “absent qualia”.
