Nikolai Berdyaev describes this book as "a philosophical autobiography or a history of spirit and self-knowledge." This book is not only autobiographical; it is also a work of critical self-inquiry: Berdyaev subjects his ideas and his life to philosophical scrutiny, in order to discover his "own image and ultimate destiny." In passing, he elucidates the most important elements of his personalistic philosophy: freedom, creativeness, and divine-humanity. By plumbing the depths of his soul, Berdyaev felt that he could help formulate and resolve certain crucial problems concerning human destiny and contribute to the understanding of our era. 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."
