What philosophical names, concepts and questions are hidden behind the now so fashionable, but difficult to pronounce and not entirely understandable word “existentialism”? How has the philosophy of existentialism influenced culture and expressed the worldview of modern man? What is the border situation, axial time and authentic existence? The philosopher and historian Pyotr Ryabov talks and reflects on Blaise Pascal, Søren Kierkegaard, Miguel de Unamuno and José Orgeta y Gasset, Lev Shestov and Nikolai Berdyaev in a course of lectures.
