Imagine your mind is a rider on a massive elephant. You, the rational rider, think you're in charge, but the powerful elephant—your emotions and intuitions—often has its own agenda. In The Happiness Hypothesis, psychologist Jonathan Haidt brilliantly explores this divided self. He tests ten great ideas from ancient wisdom against modern scientific research to reveal why happiness is so elusive and how we can finally align the rider and the elephant to lead a more satisfying, meaningful life.
