Friedrich August von Hayek (1899–1992) — one of the greatest philosophers and economists of the 20th century, a Nobel Prize laureate in Economics. In the book “The Fatal Conceit,” Friedrich August von Hayek, using an evolutionary approach from the perspective of an economist, explores the nature, origin, selection, and development of moral principles of socialism and market relations. He also summarizes his reflections on the destructive nature of socialist ideas in the 19th and 20th centuries, as well as the reasons that made the failure of all projects to build a socialist society inevitable.
