US author Robert Wright delves into the science and philosophy of meditation, mindfulness and Buddhism in his latest book, Why Buddhism is True. Wright argues that through meditation and mindfulness, humans can overcome the constraints imposed by natural selection. Those constraints are things like anxiety, regret and hatred which cloud the way humans perceive the world and their place in it. Robert has been writing about science, history and religion for thirty years and is the author of several books including The Evolution of God, Nonzero: The Logic of Human Destiny, The Moral Animal and Three Scientists and Their Gods: Looking for Meaning in an Age of Information. He joins Kathryn to talk about how humans can live kinder, happier lives.
