MARBURGO, SCHOOL of. - It is one of the two principal tendencies of German neo-Kantianism; its founder was Hermann Cohen (v. 1842-1918); and its principal continuators were Paul Natorp (v. 1854-1924) and Ernst Cassirer (1874-1945).
Unlike the neo-Kantianism of the south-west, of Freiburg and Heidelberg, which applied itself to the “philosophy of values,” the school of M. instead sought to clarify the foundations of the mathematical and natural sciences through the theory of “productive thought,” elevating logic to the status of a fundamental discipline. The philosophy of N. Hartmann (1882-1950) was also connected with the school of M. in its first phase; he later approached phenomenology in order to construct a metaphysics and a theory of values that made substantial concessions to traditional realism (v. NEOCRITICISMO).
