Ideas of the 20th Century

In our introductory lecture, Dr. Bonevac reveals the interdisciplinary roots of 20th-century thought, tracing how the Scientific, Agricultural, and Industrial Revolutions reshaped society and human life. He shows that as progress brought prosperity, it also sparked a lasting philosophical tension between the “manifest image” of free, rational agency and the “scientific image” of a physically-governed world. We see how this unresolved clash—between reason, morality, and determinism—remains a defining challenge of modernity.

In lecture two, we encounter the crisis of belief in the 20th century, examining how tensions between scientific and manifest worldviews led to abandoning traditional values. We discuss Hume's is-ought problem and responses from Wittgenstein's transcendental ethics, Nietzsche's relativism and "death of God," to Dostoevsky's Grand Inquisitor. The lecture concludes by examining constrained versus unconstrained visions, highlighting the dangers of abandoning absolute values and the slide toward narcissism without external moral anchors.

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.

In our introductory lecture, we learn about early 20th-century thinkers who warned against intellectual and cultural trends that threatened Western civilization—Miguel de Unamuno, Julien Benda, and José Ortega y Gasset. Unamuno rejected reductive views of humanity, emphasizing emotion, individuality, and treating people as ends in themselves. Benda criticized intellectuals who abandoned transcendent ideals for political fanaticism, while Ortega’s perspectivism and critique of mass media warned of conformity, “mass man,” and the erosion of civilization—developments that foreshadowed totalitarianism.

In lecture two, we examine the rise of totalitarianism in 20th-century Europe through fascist and communist movements in Italy, Russia, and Germany. First, we study Mussolini’s fascism as a nationalist system built on state supremacy, propaganda, and the subordination of individual rights. Next, we analyze Stalin’s Soviet Union, focusing on collectivization, political purges, and mass repression. Finally, we learn about Hitler’s rise in Germany, showing how economic crisis and political instability enabled the Nazi regime to establish the most destructive form of totalitarian rule. We conclude by examining how Western intellectuals defended these brutal regimes despite evidence of their atrocities.

In lecture three, we explore existentialism, which emerged prominently during and after World War II, focusing on its themes of absurdity and meaning in human life. Dr. Bonevac covers key thinkers like Jean-Paul Sartre, Albert Camus, and Simone de Beauvoir, who argue that existence precedes essence and that individuals must create their own meaning in an inherently meaningless world. The discussion examines critical responses from Saul Bellow and C.S. Lewis, who argue that existentialism artificially isolates individuals from universal moral truths and spiritual dimensions that are inherently known to all humans, suggesting that meaning and purpose are not self-created but discovered through our shared humanity and objective moral order.
