“In accounts of men in battle, there is an incredible adrenaline rush from group-versus-group conflict. The fervor and passion of partisans is clearly rewarding; and if it's rewarding, it involves dopamine; and if it involves dopamine, then it is potentially addictive.”

“It really is a fact that liberals are much higher than conservatives on a major personality trait called 'openness to experience.'

“Let me say it diplomatically: Most religions are tribal to some degree.”

“Liberals are my friends, my colleagues, my social world.”

“Morality binds and blinds. It binds us into teams... but thereby makes us go blind to objective reality.”
