Psychologist Paul Bloom discusses about his new book The Sweet Spot, and ponders whether it’s necessary to experience suffering in order to live a fulfilling, meaningful life. He discusses the rich philosophical history of the question: what does it mean to be happy? He also talks about why some people are drawn to scary movies, whether or not to plug in to the Matrix, and why a good paradigm for a well-lived life might be found in the example of… a stand-up comedian.
