Abstract
IT IS CHARACTERISTIC OF KANT that he interprets pure practical reason as will. He thereby revolutionizes the notions of both reason and the will. Reason is conceived as interest, a motivating power, even a self-sufficient telos. Moreover, the will is understood as a rational power, that is, as initially structured by the form of law, and striving for universality in both its inner operation and the way it ought to shape the outside world. For such a will, being rational also means being self-constituting, or autonomous, and self-willing, that is, seeking rationality as end-in-itself.
