Owing to a genral dissatisfaction with hedonistic theories of value, a number of recent discussions have sought to identify an agent's selfinterest, individual utility, or personal welfare with what the agent most wants to do, all things considered. Two features of these accounts merit special attention for the argument in this paper. First, on such accounts any desire or aversion which persists in the face of complete information is logically relevant to the determination of an agent's self interest. This includes (...) apparently altruistic desires like a desire for another's happiness as well as more narrow and self-regarding desires like a desire to eat a good meal. Second, when the agent finds himself in a situation where he must choose between incompatible desires, his informed preference determines the act which is most in his self-interest. (shrink)
