Robert Wright famously explained in 'The Moral Animal' how evolution shaped the human brain. The mind is designed to often delude us, he argued, about ourselves and about the world. And it is designed to make happiness hard to sustain. But if we know our minds are rigged for anxiety, depression, anger and greed, what do we do? Wright locates the answer in Buddhism, which figured out thousands of years ago what scientists are only discovering now. Buddhism holds that human suffering is a result of not seeing the world clearly - and proposes that seeing the world more clearly, through meditation, will make us better, happier people.
