Rational Choice and Action Omnipotence

A theory of rational choice is a theory of how an agent should, rationally, go about deciding what actions to perform at any given time. For example, I may want to decide whether to go to a movie this evening or stay home and read a book. The actions between which we want to choose are perfectly ordinary actions, and the presumption is that to make such a decision we should attend to the likely consequences of our decision. It is assumed that these decisions must be made in the face of uncertainty regarding both the agent’s initial situation and the consequences of his actions.
