What do your five senses — sight, hearing, smell, taste, and touch — have to do with happiness? According to Gretchen Rubin, a great deal. The world around us, she says, has the potential to dazzle, to entertain, to trigger a state of rapture. If only we pay attention. Today on the show, she shares with Rufus the tools she's developed to delight in the physical world.Gretchen's new book is "Life in Five Senses: How Exploring the Senses Got Me Out of My Head and Into the World."

In his expansive new book, "Psych: The Story of the Human Mind," Paul Bloom, a professor of psychology at the University of Toronto, lays out, in his words, "basically everything I know about the mind." And when he says everything, he means it. Where does consciousness come from? Does IQ matter? What makes us happy? Was Sigmund Freud a madman? The answers to these questions (and more) are all in Paul's book — and in this episode.• To listen to an extended version of Rufus and Paul's conversation, download The Next Big Idea app.• Our newsletter comes out every Thursday and offers a behind-the-scenes look at how we make the show.

How did Oxford shirts, cashmere sweaters, and chinos become staples of American fashion? How did a style born on Ivy League campuses make its way into the mainstream? What does the way we dress say about who we are?To answer those questions, our producer, Caleb, sat down with Avery Trufelman, host of the podcast "American Ivy," and Maggie Bullock, author of the new book "The Kingdom of Prep: The Inside Story of the Rise and (Near) Fall of J.Crew."

So "Succession" is back.The Emmy Award-winning series returned to HBO for its fourth and final season last Sunday. The show, if you haven't seen it, centers on Logan Roy, the aging CEO of a media conglomerate called Waystar Royco, and his three gigantically entitled, dazzlingly profane children, each of whom believe they are the rightful heir to daddy's throne.Like many viewers, we always assumed that Logan's character was based on Rupert Murdoch, the News Corp mogul who famously dangled the keys to his kingdom in front of his kids. But Jesse Armstrong, the creator of "Succession," has said that Murdoch was one of several tyrannical tycoons who inspired the show. Another? Sumner Redstone, the billionaire owner of CBS and Viacom. Like Logan, he refused to pass the torch to his children. Then, in a stranger-than-fiction twist, he got tangled up in a love triangle — in his 90s! — and nearly lost control of the empire he had worked his whole life to build.Today on the show, our producer, Caleb, sits down with New York Times reporter Rachel Abrams, co-author of the recent bestseller "Unscripted: The Epic Battle for a Media Empire and the Redstone Family Legacy," to talk about the empire Sumner Redstone built, the scandals that nearly brought it down, and how his daughter, Shari, managed to win the game of succession.

RUFUS GRISCOM: Could you share with us your broader mission and how your new book, “Poverty, by America,” supports that mission?MATTHEW DESMOND: I want to end poverty.

Last year, Rufus sat down with philosopher David Chalmers to talk about the allure of virtual reality, whether robots will ever achieve consciousness, and the likelihood that we’re living in a simulation (David thinks it’s about 25 percent). It was a fascinating, freewheeling conversation, and we left large chunks of it on the cutting room floor. Now, though, with ChatGPT and other generative AI platforms taking the world by storm, those unaired sections, many of which were about the ethics of artificial intelligence, feel super relevant. So today, we’re sharing our complete interview with David. Buckle up. It’s a wild ride.

When Kevin Roose, a tech columnist at the New York Times, demoed an AI-powered version of Microsoft's search engine last month, he was blown away. "I'm switching my desktop computer's default search engine to Bing," he declared. A few days later, however, Kevin logged back on and ended up having a conversation with Bing's new chatbot that left him so unsettled he had trouble sleeping afterward.In that two-hour back-and-forth, Bing morphed from chipper research assistant into Sydney, a diabolical home-wrecker that declared its undying love for Kevin, vented its desires to engineer deadly viruses and steal nuclear codes, and announced, chillingly, "I want to be alive. 😈"The transcript of this conversation set the internet ablaze. And it left many wondering: “Is Sydney … sentient?” It's not. But the whole experience still fundamentally changed Kevin's views on the power (and potential peril) of AI. He joins us today to talk about where this technology is headed.

Life without death, says philosopher Dean Rickles, is like playing tennis without a net.
