Ideas of the 20th Century

Mar 19, 2026

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 lecture four, we examine the rise of conservatism and progressivism in the 1910s and 1920s and their lasting impact on American politics. Focusing on Woodrow Wilson’s top-down, state-centered vision of freedom, we contrast it with the laissez-faire policies of Harding and Coolidge that fueled the economic boom and cultural dynamism of the Roaring Twenties. Dr. Bonevac concludes by highlighting both the era’s remarkable achievements and a growing intellectual elite increasingly at odds with the society it was meant to serve.

In lecture five, we study the Russian Revolution's roots in Marxist philosophy, examining how Marx's materialism reduced ethics to tactics serving class interests and identified human essence with production. We trace Lenin's radical departure from Marx's economic determinism, implementing totalitarian rule through systematic terror that killed hundreds of thousands. The discussion highlights fundamental problems with communist theory including problems of motivation, the emergence of new ruling elites, and economic collapse that forced Lenin to partially restore private property before his death.

In lecture six, we explore the profound impact of World War I on Western intellectual thought through the poetry of W. B. Yeats and T. S. Eliot, examining how both poets grappled with the collapse of traditional values and the search for meaning in a fractured civilization. We analyze Yeats's cyclical view of history in "The Second Coming" and his quest for spiritual permanence in "Sailing to Byzantium," alongside Eliot's fragmented vision in "The Waste Land," which depicts a spiritually barren modern world. The lecture concludes by highlighting how both poets, despite their different approaches, ultimately argue that life requires connection to something eternal or larger than oneself to have meaning.

In lecture seven, we explore the contrasting perspectives of Rudyard Kipling and F. Scott Fitzgerald as voices of the 1920s, examining their different responses to the post-World War I era. We examine Kipling's "ethics of civilization," emphasizing traditional wisdom, social institutions, and long-term survival over abstract ideals, illustrated through poems like "If" and "The Gods of the Copybook Headings." We then analyze Fitzgerald's "This Side of Paradise," depicting the lost generation's moral drift after WWI, torn between external values and internal meaning, ultimately finding only self-knowledge amid disillusionment.

In our eighth and final lecture, we investigate how World War I trauma created "unfathomable reservoirs of the absurd" that veterans couldn't express, leading to Freud's psychoanalytic theories gaining cultural prominence. We explore Freud's dream interpretation, his id-ego-superego model, and his controversial death drive theory. We then analyze how Freudian ideas influenced cultural movements, particularly Luigi Pirandello's theatrical exploration of multiple, contradictory selves, and the Surrealist movement's attempt to access and express this hidden psychological truth through art that suspends rational consciousness.

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.

In lecture four, Dr. Bonevac discusses freedom through Friedrich Hayek’s economic philosophy and George Orwell’s warnings about totalitarianism. Hayek argues that socialism, despite its appeal as a rational pursuit of the common good, ultimately undermines individual liberty, concentrates power, and fails because centralized planning cannot manage the complexity of society. Orwell complements this critique by showing how totalitarian systems manipulate language and reality, eroding truth, integrity, and human dignity. The lecture concludes by considering democratic socialism and the dangers of political language manipulation.

In lecture five, we study how mind and language connect to reality, asking whether human beings have direct access to truth or are trapped within conceptual frameworks that distort the world. Through Iris Murdoch’s work, we explore the concern that language and thought act as “nets” that filter and potentially falsify reality, casting doubt on objective knowledge. The lecture then turns to postmodernism, particularly Jean-François Lyotard’s rejection of grand narratives and universal truth in favor of multiple local forms of knowledge. We consider how these metaphysical questions connect to moral imperatives—ultimately arguing that the pursuit of truth is itself an ethical commitment.

In lecture six, we analyze how cultural and political upheavals of the 1960s and 70s—including the Vietnam War and Watergate—generated moral confusion and skepticism about connecting mind to reality. We examine how these crises undermined trust in institutions, leadership, and shared moral frameworks. The lecture then turns to Saul Kripke’s theory of names as “rigid designators,” arguing that language can directly connect us to reality rather than merely to concepts. We also examine Joan Didion’s reflections on morality and self-respect, which suggest that beneath cultural disagreement lies a shared moral core grounded in survival, loyalty, responsibility, and love.

In lecture seven, we consider the post-World War II revival of moral normativity, driven by the recognition of real evil and the need for objective moral standards beyond personal preference. We examine two major theories of distributive justice: John Rawls’s “justice as fairness,” grounded in the social contract, original position, and veil of ignorance, and Robert Nozick’s historical theory of justice, which emphasizes legitimate acquisition and individual liberty over patterned distributions. The lecture concludes by considering the tension between fairness and liberty, as well as Rawls’s later concerns about maintaining consensus in increasingly diverse societies.

In our eighth and final lecture, we explore the intellectual and political movements that contributed to the collapse of the Soviet Union through figures such as Aleksandr Solzhenitsyn and Václav Havel, who exposed the lies sustaining communist societies and emphasized the importance of “living in truth.” We examine Solzhenitsyn’s critique of ideology and his experiences in the Gulag system, Havel’s analysis of conformity and “living within the lie,” and the role leaders like Reagan and Thatcher played in challenging Soviet power. Dr. Bonevac concludes by considering Solzhenitsyn's warning that Western civilization's focus on human happiness rather than higher spiritual duties may lead to its own form of moral decay.
