The study of the outstanding Russian thinker Lev Alexandrovich Tikhomirov (1852-1923) is unique in its content. For the first time, human history has been analyzed in full and from a religious point of view. The book shows the emergence and logical development in human societies of religious movements, the mutual connection and continuity of religious ideas of different times, which either disappear from the historical scene or reappear, putting on new faces.
