The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

This paper demonstrates that there is an inconsistency in functionalism in psychology and philosophy of mind. Analogous inconsistencies can be expected in functionalisms in biology and social theory. (edited).

D. H. Hodgson has argued that among highly knowledgeable and rational act-Utilitarians there is no non-Circular reason to be truthful or to expect truthfulness from others; wherefore these utilitarians forfeit the benefits of communication. I reply that hodgson goes wrong by tacitly assuming that his utilitarians have no premises to reason from except those that hodgson lays down in specifying the example under consideration.
