Rationality and Revolution

The question of an action's rationality has two aspects: 1) the ‘appropriateness’ of the action given the beliefs held and 2) the ‘reasonableness’ of the beliefs themselves or of holding those beliefs. The former involves questions of motivation, the latter epistemology. This paper will concentrate on the former aspect of the question.One way of understanding rational motivation is so widely accepted as to seem incontrovertible to many of its proponents. This is the sense of rationality as maximization of utility. Although individual action is motivated by many things, the claim is that when behavior is rational it can be understood as an attempt to maximize utility. Rationality in this view has solely to do with means, not ends. The only restriction on an agent's ends is that they form a coherent set and whatever the content of the utility at which the agent aims, it is presumed to be open-ended. The theory is descriptive in that it says that (normal) people act this way most of the time and also normative in that behavior which does not fit the model is Judged irrational.
