Abstract

This thesis is a critique of functionalism in the philosophy of mind. I distinguish three tenets, or 'dogmas' of functionalism, viz: Mental states are causes of behaviour; Mental states can, in principle, be defined in non-mental terms; We understand everything, or at least everything of importance, about the mental states of people, by subsuming token mental states under one or other mental state type. ;The first dogma is rejected in the form which identifies mental state types with physical types, on the ground that it commits us to the doubtful possibilities of mental states without any relevant behaviour, and behaviour without a relevant mental state . It is found to be not mandatory in the form which identifies mental state types with functional types, on the ground that the phenomena appealed to in support of the dogma is consistent with a view of mental states which endorses the dogma in at best a trite and philosophically uninteresting sense . The second dogma is rejected on the ground that cannot account for what I call the 'affective animation' of the behaviour of creatures with mental states . I develop a concept I call personal response---the kind of response we have to other human beings as opposed to inanimate nature---and defend principle which says: Commonsense understanding that someone is in a mental state requires proneness to a personal response in relation to that person. ;Certain implications are drawn from for reductionism, for meta-ethics, and for the third dogma . I argue that the third dogma is false on the around that it cannot account for our sense of the individuality of persons, unless that very notion of individuality, which comes from quite outside functionalism, is used to gloss the idea of subsumption under a type
