Kim Bowes is an archaeologist at the University of Pennsylvania whose book, Surviving Rome: The Economic Lives of the Ninety Percent, Tyler calls perhaps his favorite economics book of 2025. By sifting through the material remains of Roman life — shoes, bricks, ceramics, and the like — she uncovers a picture of ordinary Romans who could evidently afford to buy multiple sets of colorful clothes, use gold coins for daily transactions, and eat peppercorns sourced from thousands of miles away. This vast web of commerce, she argues, both bound the empire together and provided the tax base that kept it running — and when it unraveled, Rome unraveled with it.

Tyler and Kim discuss what would surprise a modern visitor to a Roman elite home, what early Roman Christianity actually looked like on the ground, why Romans never developed formal economic reasoning, what decentralized money-lending reveals about the Roman state, whether there were anything like forward markets, why Romans continued to use coins even as the empire debased them, the economics of Roman slavery, whether Roman recipes taste any good, the Romans as hyper-scalers rather than inventors, what Rome made of China and Egypt, why Kim's not a fan of the Vesuvius challenge, the practicalities of landscape archaeology, how a vast belt of factories along the Tiber Valley went undiscovered until twenty years ago, where to go on a three-week tour of the Roman Empire, what she thinks is ultimately behind Rome's unraveling, and much more.

Arthur Brooks reckons he's on the fourth leg of a spiral-shaped career: French horn player, economist, president of the American Enterprise Institute, and now Harvard professor and evangelist for the science of happiness. His new book, The Meaning of Your Life: Finding Purpose in an Age of Emptiness, argues that happiness isn't a feeling but a combination of enjoyment, satisfaction, and meaning — the macronutrients of happiness, he calls them — and that most of us are gorging on the wrong ones. Tyler, naturally, wants to know: what's the marginal value of a book on happiness, and what does spiral number five look like?

Along the way, Tyler and Arthur cover how scarcity makes savoring possible and why knowing you'll die young sharpens the mind, what twin studies tell us about the genetics of well-being and why that's not actually depressing, the four habits of the genuinely happy, the placebo theory of happiness books, curiosity as an evolved positive emotion, the optimal degree of self-deception, why Arthur chose Catholicism rather than Orthodoxy, what the research says about accepting death, how he became an economist via correspondence school, AI's effect on think tanks, the future of classical music, whether Trumpism or Reaganism is the equilibrium state of American conservatism, whether his views on immigration have changed, what he and Oprah actually agree on, which president from his lifetime he most admires, Barcelona versus Madrid, what 60-year-olds are especially good at, why he's reading Josef Pieper, how he'll face death, and much more.

Tyler calls Paul Gillingham's new book, Mexico: A 500-Year History, the single best introduction to the country's past—and one of the best nonfiction books of 2026. Paul brings both an outsider's eye and ground-level knowledge to Mexican history, having grown up in Cork — a place he'd argue gave him an instinctive feel for fierce local autonomy and land hunger —earning his doctorate on the Mexican Revolution under Alan Knight at Oxford, and doing his fieldwork in the pueblos of Guerrero.

He and Tyler range across five centuries of Mexican history, from why Mexico held together after independence when every other post-colonial superstate collapsed, to why Yucatán is now one of the safest places on earth, what two leaders from Oaxaca tell us about Mexican politics, how Mexico avoided the military coups that plagued the rest of Latin America, what Cárdenas's land reform actually achieved versus what it promised, whether the ejido system held Mexico back, why Mexico worried too much about land and not enough about human capital, how Mexico's fertility rate fell below America's, why Guerrero has been violent for two centuries, why the new judicial reforms are a disaster, where to find the best food in Mexico and Manhattan, what a cache of illicit Mexican silver sitting on a ship in the English Channel has to do with his next book, and more.
