The article deals with the main tendencies in the studies of Russian neo-Kantianism in Poland. Although the number and quality of research in the history of Russian neo-Kantianism still cannot be equated with those of the history of German neo-Kantianism, the situation of these studies is constantly changing for the better. The authors mark the undeniable progress in the studies of Russian neo-Kantianism in Poland in the recent years: there are monographs, articles, collections, research projects on particular thinkers or themes (...) related to the history of Russian neo-Kantianism. The authors consider A. Noras’s idea of the development of neo-Kantianism into post-neo-Kantianism rather heuristic. One of the main features of this development is the ontologization of the cognitive process. This “ontological turn”, typical of Russian neo-Kantianism, in particular as represented by S. Hessen, V. Sesemann, B. Jakovenko, is, on the one hand, the hallmark of the entire Russian philosophy and, on the other, it brings together the philosophical efforts of Russian neo-Kantians and the conception of the author of the “new ontology” – N. Hartmann. (shrink)
