Emotion, Reason, and the Gap Between Us and Them

Neuroscientist Joshua Greene argues that our brains were designed for tribal life, for getting along with a select group of others (Us) and for fighting off everyone else (Them). But modern times have forced the world’s tribes into a shared space, resulting in epic clashes. Moral Tribes: Emotion, Reason, and the Gap Between Us and Them combines neuroscience, psychology, and philosophy to reveal the underlying causes of modern conflict. Dr. Greene is an award-winning teacher and scientist, and he directs Harvard University’s Moral Cognition Lab, which uses neuroscience and cognitive techniques to understand how people really make moral decisions.
