In the article the author tells us about the religious essence of Russian philosophy as its basic characteristic since in was founded in the middle of the 19th century until now. Russian philosophy never existed or couldn?t have existed in the European state of mind because it?s essentially a philosophic interpretation of religious faith. According to the author?s opinion, European philosophy, as a whole, has left the borders of the Christian spiritual plain by making the anthropocentric principle of thinking the absolute, which took it into positivism and nihilism. Russian philosophy hasn?t left the Christian spiritual field and has kept a theocentric (classical) type of thinking till the present day. The stand-point of the believing mind which rejects transcendental, as well as any other self foundation of the European philosophy. From the beginning until the present day, Russian philosophy has been opposed to the Descartes-Kant?s way of thinking. Western modern philosophy killed God intellectualy, and postmodern killed the Man as well, moving its philosophy into an empty space of ?transindividual constructions?. Ivan Kirejevski founded an ontological-gbnoseological model of Russian secular Christian philosophy in the middle of the 19th century, and from that, later, other branches of Russian philosophy developed: ontological-cultural (Danilevski, Leontjev), ontological-anthropological (Solovjov, Berdjajev, Ern). Briefly, Russian philosophy is what Russian national culture, based on Orthodox Christian views, can say about the World and the Man using the conceptual language.
