In Chapter V of his book Res Cogitans — “On What One Knows” — Zeno Vendler attempts to maintain the thesis that the objects of knowledge and belief are incompatible, i.e., that the immediate object of believing is a picture of reality and “the immediate object of knowing is not a picture of reality but reality itself”. We shall argue that he fails in this attempt because his “incompatibilism” depends on the view that the that-clauses which are the basic verb (...) objects of know and believe are of a type which reflect a distinction between the subjective and objective dimensions of the mental world; and it is exactly this which he does not establish;and question the philosophical significance of the wh-nominal.In Chapter IV — “Propositions” — Vendler tries to draw a distinction between “the subjective and objective dimensions of the mental world”. The subjective dimension corresponds to the world of propositions. (shrink)

Some philosophers have conflated functionalism and computationalism. I reconstruct how this came about and uncover two assumptions that made the conflation possible. They are the assumptions that (i) psychological functional analyses are computational descriptions and (ii) everything may be described as performing computations. I argue that, if we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions. # 2004 Elsevier Ltd.
