Abstract

The thesis that I have been trying to establish in this dissertation is that ethical systems are constructed on the basis of certain presuppositions about the temporal horizon in which human beings live, and most importantly, of the horizon within which they ought to live. In order to take a step towards establishing this claim, I examine what I take to be the two most powerful ethical theories in the western tradition, Aristotelianism and Kantianism, reconstructing their implications for the relationship between ethics and temporality. I argue that Aristotle's ethics are intended to moderate the future orientation of his psychology by stressing the importance of the past. I suggest that it is possible to provide a temporal reading of Kantian ethics by emphasizing the notion of objective ends. But since this is one of the most tenuous elements in his system, the results will always be unstable. Finally, I argue that Habermas's discourse ethics can be read as an attempt to mediate the differences between Aristotle and Kant, and that it rests on a temporal horizon that deserves serious consideration. This is a temporal horizon that results from understanding the importance of tradition for questions of self-identity, on the one hand, and on the other of universality for questions of justice
