Abstract

We shall defend two theses: (a) if a decision situation exhibits a certain causal structure, then decision theory is in trouble, because the derivation of expected utilities fails; (b) this causal structure in fact obtains in a specific, but very common kind of situation, namely, when the intrinsically evaluated psychological states are in the domain of the utility function. It will be apparent that the problem is but a variant of Joseph Butler's criticism of hedonism. Thus, in a sense, the point of our paper is that modern theorizing about practical deliberation has not dealt seriously with Butler's criticism.
