and founder of the Marburg School. Cohen defended Kantian views of the a priori, but without leaving a place for the noumenal. He found Kantian respect for the moral subject implicit in the Judaic tradition, and in later years became a major influence on Jewish thought. His principal legacy is Die Religion der Vernunft aus den Quellen des Judentums (1919) trs. as Religion of Reason out of the Sources of Judaism (1972).
