**Intact Gift Giving Condition book**

In this provocative and sweeping chronicle of 20th century history, acclaimed historian Paul Johnson argues that the confirmation of Einstein’s theory of relativity set in motion a chain of events that replaced moral absolutes with a destructive new era of moral relativism. The modern world began on May 29, 1919. This powerful work of intellectual history traces how the ideas of Marx, Freud, and Einstein were tragically twisted into justifications for the terrifying rise of totalitarianism. Johnson uncovers the horrifying consequences of social engineering, from Lenin's and Stalin’s brutal experiments to the collectivist ideologies that swept the globe.
