When Bo Seo was 8 years old, his family moved from Korea to Australia. He did not speak a world of English. At school, to deflect attention from his inarticulacy, he became an agreeable wallflower. But that all changed when Bo’s fifth-grade teacher introduced him to competitive debate. Bo was hooked, and in the years to come, he’d not only win two debate world championships but also go on to coach the Australian national team as well as the Debating Union at Harvard, where he earned his undergraduate degree and is currently a law student.

Earlier this year, Bo published his first book, “Good Arguments: How Debate Teaches Us to Listen and Be Heard,” which was chosen by our curators as one of the year’s eight best works of non-fiction. In today’s episode, Bo sits down with one of those curators, Adam Grant, to share time-honored techniques for getting your point across, changing minds without hurting feelings, dealing with bullies, and knowing when to shut up.

“Life is a game. There’s no way to understand the human world without first understanding this. Everyone alive is playing a game whose hidden rules are built into us and that silently directs our thoughts, beliefs and actions. This game is inside us. It is us. We can’t help but play.”

So begins “The Status Game,” a new book by acclaimed writer Will Storr.

He continues: “We play for status, if only subtly, with every social interaction, every contribution we make to work, love or family life and every internet post. We play with how we dress, how we speak and what we believe. … Life is not a journey towards a perfect destination. It’s a game that never ends. And it’s the very worst of us.”

Does it have to be?

We may not be able to quit the status game, but Will says we can learn to play it better. In this episode, he explains how.

If the human race lasts as long as a typical mammalian species and our population continues at its current size, then there are 80 trillion people yet to come. Oxford philosophy professor William MacAskill says it's up to us to protect them.

In his bold new book, "What We Owe the Future," MacAskill makes a case for longtermism. He believes that how long we survive as a species may depend on the actions we take now.
