Ep134 "What do brains teach us about morality?" with Joshua Greene

Joshua Greene's 'Moral Tribes' delves into the complexities of human morality, arguing that our brains evolved for cooperation within groups, but struggle with intergroup relations. The book introduces the concept of 'deep pragmatism' as a metamorality to foster cooperation between groups with conflicting moral intuitions. Greene uses the analogy of 'thinking fast and slow' to differentiate between intuitive moral judgments and detached moral reasoning. He suggests that utilitarianism, or 'deep pragmatism,' can serve as a common currency for making trade-offs among competing values and interests. By understanding our evolved moral psychology, Greene proposes ways to bridge divides and promote cooperation in an increasingly interconnected world.
