The Moral Molecule

A Revolution in the Science of Good and Evil Why do some people give freely while others are cold hearted? Why do some people cheat and steal while others you can trust with your life? Why are some husbands more faithful than others—and why do women tend to be more generous than men? Could they key to moral behavior lie with a single molecule? From the bucolic English countryside to the highlands of Papua New Guinea, from labs in Switzerland to his campus in Souther California, Dr. Paul Zak recounts his extraordinary stories and sets out, for the first time, his revolutionary theory of moral behavior.  Accessible and electrifying, The Moral Molecule reveals nothing less than the origins of our most human qualities—empathy, happiness, and the kindness of strangers.
