In this work, Berdyaev tells us that man''s "I," his consciousness, is thrust up against a world of impersonal objects (the "objectified" world) and thus finds itself in a condition of alienation and isolation. In five ontological and epistemological meditations Berdyaev clarifies this condition of "objectification" and suggests ways it can be overcome, based on his "personalistic," "existential" philosophy. He shows how this philosophy can serve to counteract objectification and human isolation. Emphasis throughout is placed on modes of human communion and solitude in society. The Russian philosopher Nikolai Berdyaev (1874-1948) was one of the greatest religious thinkers of the twentieth century. His philosophy goes beyond mere thinking, mere rational conceptualization, and tries to attain authentic life itself: the profound layers of existence that are in contact with God''s world. Berdyaev directed all of his efforts, philosophical as well as in his personal and public life, at replacing the kingdom of this world with the kingdom of God. According to him, we can all attempt to do this by tapping the divine creative powers which constitute our true nature. Our mission is to be collaborators with God in His continuing creation of the world. This is what Berdyaev said about himself: "Man, personality, freedom, creativeness, the eschatological-messianic resolution of the dualism of two worlds - these are my basic themes."
