Luke Burgis on Mimetic Desire, Catholicism, and the Age of Social Contagion show art Luke Burgis on Mimetic Desire, Catholicism, and the Age of Social Contagion

Conversations with Tyler

Luke Burgis left Wall Street after two years, founded a few successful companies in his twenties, then walked away to spend three years in a Roman seminary on the path to the priesthood. He now runs the Cluny Institute and teaches at Catholic University. His book Wanting made René Girard legible to a general audience; the new one, The One and the Ninety-Nine, takes mimetic theory into the dynamics of self and crowd in an age of social contagion. He joined Tyler to discuss whether the age of pessimism is ending, why the Anglo world in particular seems so unhappy, whether Dostoevsky or Thomas...

Daron Acemoglu on Liberalism, Automation, and the Educated Elite show art Daron Acemoglu on Liberalism, Automation, and the Educated Elite

Conversations with Tyler

Daron Acemoglu returns for his second appearance with a new book, What Happened to Liberal Democracy?, which Tyler reads as an attempt to redefine and revitalize liberalism for our times. Where Daron’s first visit was about how states and societies contend for the narrow corridor in which liberty survives, this one asks what liberals themselves got wrong, and the answer implicates the educated elite—that is to say, you. Tyler and Daron discuss what's wrong with social contract theories and Rousseau's general will, whether Acemoglu is more objectivist than Rorty, why he blames left...

Julia Ioffe on Russian Women, Missing Men, and the Roots of Autocracy show art Julia Ioffe on Russian Women, Missing Men, and the Roots of Autocracy

Conversations with Tyler

Julia Ioffe left the USSR as a child and came back as an adult journalist to find that the confident, credentialed women she remembered from her Soviet childhood had largely been supplanted by those chasing marriage and domesticity instead. That disorienting reversal is the engine of her book Motherland, a National Book Award finalist that reconstructs modern Russian history almost entirely through its women. Her account, drawn from her own family's history as well as the archives, keeps returning to one plain observation: Soviet policy pushed women into the workforce, the medical schools,...

Andrew Graham-Dixon on Vermeer, a Forgotten Sect, and Underrated Artists show art Andrew Graham-Dixon on Vermeer, a Forgotten Sect, and Underrated Artists

Conversations with Tyler

Andrew Graham-Dixon’s new book, Vermeer: A Life Lost and Found, rests on the conviction that you cannot understand what's in a painting without knowing what its maker was thinking about. In Vermeer's case, that context includes a forgotten liberal sect — the Remonstrants and Collegiants, Christians without a church who believed peace would come through reading and toleration rather than a returning Messiah. Recover that world and a woman alone in a sunlit room is a radical image in a Europe where half of Germany had just died in war. If he's right, the label beside every Vermeer in every...

Chase Koch on Principles, Music, and Overcoming Entropy show art Chase Koch on Principles, Music, and Overcoming Entropy

Conversations with Tyler

Chase Koch grew up receiving Sunday philosophy lessons from his father Charles and, by his own account, spent most of them half asleep while his sister supplied the answers. The principles didn’t land until he lived them: throwing tennis matches as a bored teenager, getting shipped off to shovel manure at a feed yard twelve hours later, then spending five years battling Brazilian bureaucracy to build a fertilizer terminal that should have taken one. Today he is Executive Vice President of Origination and Partnerships, leader and donor to Stand Together, plays lead guitar in a band...

Joel Mokyr on Clans, Corporations, and a Culture of Growth show art Joel Mokyr on Clans, Corporations, and a Culture of Growth

Conversations with Tyler

Joel Mokyr co-won the 2025 economics Nobel for exploring the question that traces back to the beginning of economics: how did sustained economic growth suddenly become normal? For nearly all of human history, cleverness didn't compound. What changed, according to Mokyr, was twofold: first, you need to know why something works, so that one advance can seed the next; second, you need a culture willing to tolerate the disruption. His new book contrasts Europe with China, showing how Europeans learned to cooperate with people they weren't related to, in guilds, monasteries, cities, and...

Joanne Paul on Thomas More and the Tudor World show art Joanne Paul on Thomas More and the Tudor World

Conversations with Tyler

Joanne Paul is a historian at the University of Sussex, author, and a go-to Tudor expert on YouTube. She tells Tyler she's drawn to the 16th century because it sits between the medieval and the modern, and because its paths not taken are a way of asking whether our own world had to turn out this way. Her biography Thomas More: A Life takes its subject in that spirit, refusing to reduce More to either martyr or monster. Tyler and Joanne discuss how More influenced Erasmus, what to make of Utopia, why fear drove More's persecution of heretics, how Holbein's portraits of More and Cromwell differ,...

Dave Baszucki on Roblox, Teen Entrepreneurs, and the Future of Play show art Dave Baszucki on Roblox, Teen Entrepreneurs, and the Future of Play

Conversations with Tyler

Dave Baszucki is co-founder and CEO of Roblox, the user-generated gaming platform where all the games are built by the community itself. With over 100 million daily active users and projected revenue bookings of $7 billion this year, it is one of the largest gaming economies in the world—and one that has made millionaires out of teenage developers in Argentina, South Korea, and everywhere in between. Tyler and Dave explore why Roblox decided early against prioritizing advertising revenue, why Dave thinks the main competition of Roblox is its own execution speed rather than Fortnite, whether...

Katja Hoyer on Weimar, the GDR, and the German Character show art Katja Hoyer on Weimar, the GDR, and the German Character

Conversations with Tyler

Katja Hoyer is a German-British historian who has made a career out of explaining Germany to the world—and, just as importantly, to Germans themselves. Born in East Germany in 1985 and now based in Britain, she has written acclaimed histories of the German Empire, the GDR, and most recently the Weimar Republic. Tyler and Katja discuss why communism made East Germans more loyal to the system while it bred dissidents in Poland and Hungary, how happy or unhappy life in the GDR actually was, Tyler's own bleak day-trip to East Berlin in 1984, the underrated literature of the GDR (Christa Wolf,...

Toby Wilkinson on Ptolemaic Egypt and the First Great Commercial Civilization show art Toby Wilkinson on Ptolemaic Egypt and the First Great Commercial Civilization

Conversations with Tyler

Toby Wilkinson is one of the world's leading Egyptologists, whose books have ranged across the full sweep of pharaonic history. His latest, The Last Dynasty: Ancient Egypt from Alexander the Great to Cleopatra, covers the 300-year Ptolemaic period — stranger and more modern-feeling than the Egypt of the pyramids, built around commerce and cosmopolitanism rather than divine kingship, and home to the greatest concentration of scientific talent the ancient world ever saw. Tyler and Toby cover how Alexander took over the empire almost without a fight, why Alexandria became the Manhattan of the...

Tyler considers Diarmaid MacCulloch one of those rare historians whose entire body of work rewards reading. This work includes his award-winning Cranmer biography, his sweeping histories of Christianity and the Reformation, and his latest on sex and the church, which demonstrates what MacCulloch calls the historian's true vocation: unsettling settled facts to keep humanity sane.

Tyler and Diarmaid explore whether monotheism correlates with monogamy, Christianity's early instinct towards egalitarianism, what the Eucharistic revolution reveals about the cathedral building boom, the role of Mary in Christianity and Islam, where Michel Foucault went wrong on sexuality, the significance of the clerical family replacing the celibate monk, why Elizabeth I—not Henry VIII—mattered most for the English Reformation, why English Renaissance music began so brilliantly but then needed to start importing Germans, whether Christianity needs hell to survive, what MacCulloch plans to do next, and more.
