This detailed study examines the close cooperation between the two main figures of the Marburg School, Hermann Cohen (1842-1918) and Paul Natorp (18541924), primarily from the time that Natorp came to the University of Marburg in 1880 to write his HabilitatiollSschrift under Cohen until Cohen's resignation from Marburg in 1912. It is a common view that during this period Cohen and Natorp were of one philosophical mind: Cohen developed the basic premises of Marburg Kantianism, first in his explications of Kant's three Critiques, and later in his own philosophical system [Logic of Pure Cognitioll (1902), Ethics of the Pure Will (1904), and Aesthetics of Pure Feeling (1912)], while Natorp used these premises in his historical studies (e.g., on Descartes and Plato) and in the construction of his social pedagogy.
