The article brings to light the idea that Russian Neo-Kantians were among the first in the history of European philosophy to recognize the significance and originality of Hermann Cohen’s philosophical system. In particular, they identified two related points that revealed the ingenuity of the great Marburg thinker: the creation of a new philosophical system and the synthesis of Kant and Hegel within that system. The article also discusses the particular focus on the part of Russian philosophers at the turn of the twentieth century on Cohen’s ethical theories. It is argued that the full value of the German-Jewish thinker’s work for Russian philosophy is only starting to be appreciated, and that the work of Russian Neo-Kantians will be a great help in this endeavor. © Taylor & Francis Group, LLC.
