Priest of the Russian Orthodox Church Pavel Aleksandrovich Florensky (1882–1937) is a man-university, a man-epoch, a man-universe. Turning to the biography and key works of Father Paul, you understand that there is not a single field of knowledge in which Florensky would not leave a mark: theology and philosophy, art history and linguistics, ethnography and anthropology, mineralogy and engineering... And this is not only the genius of the human mind or an unquenchable thirst for knowledge. First of all, this is the desire for the Truth. And Truth does not tolerate division, it is revealed only in unity and unity. Modern society, the author believes, needs such a person, an example of such a unifying gift, an integral worldview, and a tireless pursuit of Truth. The martyrdom of Pavel Florensky and his ascent to Calvary became the triumph of Orthodoxy. And the light of his spiritual achievement continues to shine on all of us. This is what inspired the author to write the book.
