James Baldwin believed that America has been lying to itself since its founding. An insightful commentator on Black identity, American democracy, and racism, he saw something deep and ugly and stubborn in American culture, and never hesitated to call it by its name — to bear witness, regardless of what it cost him. As the United States continues to reckon with all aspects of its history, writer and professor Eddie S. Glaude Jr. guides us through the meaning and purpose of James Baldwin's work, and how his words can help us navigate our current moment.For sponsor-free episodes of Throughline, subscribe to Throughline+ via Apple Podcasts or at plus.npr.org/throughline.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

In 1899, Elie Metchnikoff woke up in Paris to learn that he had defeated old age. At least, that's what the newspaper headlines said. Before long he was inundated with mail from people begging him to help them live forever. The only problem? He didn't know how to do it. At the time, Metchnikoff was one of the world's most famous scientists. And he believed aging was a disease he could cure. He dedicated his life to that quest, spending his days interviewing centenarians, pulling gray hair out of colleagues and old dogs, and boiling strawberries — all in the pursuit of eternal youth. If you've ever had yogurt for breakfast, you likely have Metchnikoff to thank.Today on the show: Elie Metchnikoff's quest, his life — and his deathLearn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

In April 1938, an Oklahoma bank robber was arrested for carrying an unregistered sawed-off shotgun across state lines. The robber, Jack Miller, put forward a novel defense: that a law banning him from carrying that gun violated his Second Amendment rights.For most of U.S. history, the Second Amendment was one of the sleepier ones. It rarely showed up in court, and was almost never used to challenge laws. Jack Miller's case changed that. And it set off a chain of events that would fundamentally change how U.S. law deals with guns.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Climate change, political unrest, random violence: modern society can often feel like what the filmmaker Werner Herzog calls "a thin layer of ice on top of an ocean of chaos and darkness." In the United States, polls indicate that many people believe law and order is the only thing protecting us from the savagery of our neighbors. This idea is often called "veneer theory." But is it true?Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

They say "everything old becomes new again." Today, that's baggy jeans, shag haircuts, 90s music, TV sitcoms – the latest version of finding comfort in nostalgia and familiarity in what came before. We constantly look for safety in the permanence of the past, or at least, what we think the past was. But, when it first appeared, nostalgia itself wasn't considered a feeling; it was a deadly disease. This episode traces the history of nostalgia from its origins as an illness to the dominating emotion of our time. And in doing so, we wrestle with its eternal paradox to both hold us back and keep us going.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

We live in divided times, when the answer to the question 'what is reality?' depends on who you ask. Almost all the information we take in is to some extent edited and curated, and the line between entertainment and reality has become increasingly blurred. Nowhere is that more obvious than the world of reality television. The genre feeds off our most potent feelings – love, hope, anxiety, loneliness – and turns them into profit... and presidents. So in this episode, we're going to filter three themes of our modern world through the lens of reality TV: dating, the American dream, and the rage machine.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
