N. Berdiaev (1874-1948), the "nostalgic of eternity" who struggles with the fever of visions, seeks behind the historical objectifications the genuine and living truth that guides the individual towards his divine destiny. He participates with unwavering passion in the dramatic struggle for the salvation of humanity from its historical fall, fights for its historical restoration, and calls it not to betray its cosmic responsibility. With this book, he attempts to reexamine the fundamental problems of Christianity in the light of spirit and truth. The nature of truth is not intellectual, it is not cognitive, it is not given to humans as an object, but it presupposes movement and tendency towards the infinite. It is the perfect completeness, which one reaches "from the way and the life". In his search, the author envisions the revelation of the new man, the transcendent and eternal one, "who actively fights in the creation of the world and himself".
