Since 2008, Big Think has been sharing big ideas from creative and curious minds. Since 2015, the Think Again podcast has been taking us out of our comfort zone, surprising our guests and Jason Gots, your host, with unexpected conversation starters from Big Think’s interview archives. 100 episodes in, like the universe itself, the show continues to expand and accelerate at speeds that boggle the imagination. One of seven siblings, Paul Theroux is the author of over 50 works of fiction and non-fiction, including The Great Railway Bazaar and The Mosquito Coast. His latest novel Mother Land is a scathing, semi-autobiographical, often painfully funny portrait of a mother’s long and insidious reign over her seven children. In this episode, Paul talks about the claustrophobia of big families, the mass migrations of peoples, colonizing Mars, and an important difference between humans and cockroaches.
