Pico Iyer gives us an end of summer lift in today’s podcast. The long-time travel writer and philosopher reflects on the persistent human struggle to understand the world and find peace. Despite millennia of evolution, division and conflict remain central to civilization. While science offers definitive answers, understanding life and relationships is more complex, according to Iyer, a longtime California figure. He says we each search for solace, aiming to piece together life’s puzzle to form an ideal picture, a theme that runs through his work, including, most recently, “The Half Known Life: In Search of Paradise.”
