 Though the term ‘Representational Theory of Mind’ is sometimes used almost interchangeably with ‘Computational Theory of Mind’, I will use it here to refer to any theory that postulates the existence of semantically evaluable mental objects, including philosophy’s stock-in-trade mentalia – thoughts, concepts, percepts, ideas, impressions, notions, rules, schemas, images, phantasms, etc. – as well as the various sorts of “subpersonal” representations postulated by cognitive science. Representational theories may thus be contrasted with theories, such as those of Baker (1995), Collins (1987), Dennett (1987), Gibson (1966, 1979), Reid (1764/1997), Stich (1983) and Thau (2002), which deny the existence of such things.
