Imagine waking up to discover that your deepest moral convictions-the principles you've built your life around-are actually products of evolutionary psychology rather than timeless truths. This realization forms the heart of Joshua Greene's groundbreaking work. While morality evolved as nature's solution to cooperation problems within groups, it created a new problem: conflict between groups with different moral systems. Today's political divisions aren't just disagreements about facts; they reflect fundamentally different moral intuitions that feel self-evidently correct to those who hold them. Liberals prioritize care and equality, while conservatives emphasize loyalty, authority, and sanctity. Each side believes their moral feelings reflect objective truth rather than tribal adaptations. This explains why moral disagreements feel so intractable-our moral machinery wasn't designed to resolve them.
