In lecture three, we analyze how early 20th-century intellectual movements like Shaw's cynicism about moral values and Italian Futurism's violent rejection of the past helped create conditions for World War I. We explore Shaw's dismissal of traditional ethics and embrace of Stalin's violence, alongside the Futurists' glorification of war and destruction as progress. The discussion concludes with WWI's catastrophic toll and its shattering of civilization's faith in progress, creating a generation that lost innocence and trust in institutions.
