Abstract

Perhaps the ultimate significance of Kant's Copernican revolution in philosophy lies in its attempted reconciliation of the transcendental, logical orientation of continental rationalism with the humanistic, psychological approach of British empiricism. With the rationalists, Kant distinguished sharply between questions concerning the causes and origins of our knowledge and questions about its limits and objective validity. Thus, a rigorous critique of psychologism, i.e. of any attempt to explain, or explain away the validity of either our cognitive or moral principles by means of an analysis of their basis in human nature or their genesis in human experience, is one of the most characteristic traits of the Kantian philosophy. Yet this transcendental, logical investigation of the nature and limits of knowledge, and of the fundamental principles of morality leads Kant back to the human subject, in whose cognitive faculties he finds the a priori principles of human knowledge and in whose autonomy he finds the basis of the categorical imperative. This gives rise to a paradoxical conception of man as on the one hand, together with the rest of creation, a part of nature, subject to its laws, and on the other hand, in his capacity as knower and actor, a rational being who not only transcends nature in the sense that he is not completely determined by its laws, but who is actually the author of these laws.
