The bond we share with dogs runs deep. The satisfaction of gentle head scratches or a round of playing fetch is simple and pure, but in other ways, the connection we have is truly unknowable.

One of the toughest things about trying to understand climate change – arguably the most important story of our time — is wrapping our minds around it. To even imagine something so enormous, so life-changing, we need a story. Some characters, a metaphor, and even some lessons learned.

What would it be like to live in a world where magic is still alive? Not weird, not woo-woo, just ordinary. 400 years ago, consulting a magician in downtown London was as unremarkable as calling a plumber today.

Do you ever feel like there’s something missing in your life? You don’t know exactly what it is. And there’s never enough time to really think about it.

America is in the midst of a new debate over how we tell our history.

In the world of internet influencers and YouTube stars, it’s not enough to be ordinary anymore. You need to be special. But where did this craze for personal branding come from? Why are we so obsessed with ourselves? To understand this cult of the self, we need to go back to 19th century spiritual movements and the rise of the huckster — and also the myth of rugged individualism. But if we’re always shouting “Me me me,” what are we losing? What has it cost us?Original Air Date: February 03, 2024Interviews In This Hour: If nobody sees you online, do you exist? — How personal branding became an American religion — Why rugged individualism is a dangerous myth — The philosophers who invented the modern selfGuests: Angelo Bautista, Tara Isabella Burton, Alissa Quart, Andrea WulfNever want to miss an episode?
