As America descends deeper into polarization and paralysis, social psychologist Jonathan Haidt has done the seemingly impossible--he has explained the origins of morality, politics, and religion in a way that speaks to everyone on the political spectrum.   Drawing on twenty-five years of groundbreaking research, Haidt shows why liberals, conservatives, and libertarians have such different intuitions about right and wrong, and why we need the insights of each if we are to flourish as a nation. Here is the key to understanding the miracle of human cooperation and the eternal curse of moralistic aggression, across the political divide and around the world.   A Vintage Shorts Selection. An ebook short.
