From a review of a book by Steven Pinker: Shakespeare: One of the First and Greatest Psychologists:
If you were to add up the number of killings by people in pursuit of what they think are moral aims, whether it’s personal vengeance, implementing justice, or hastening a utopia or messianic age, the body count would surely be higher than the victims of amoral predation and exploitation.
That’s why pure moralism does more harm than good, and why a legitimate moral concern with human welfare must work together with a scientific drive to understand the causes of wrongdoing. If, as moralists, our responsibility is to reduce suffering and enhance flourishing, then the most powerful way to do that is through analytic engagement: moral philosophy, reasoned jurisprudence, legal scholarship, and the sciences of human nature. When we can say what makes us tick, we can rearrange our environments in ways that inhibit aggression and enhance empathy, compassion and reason.
He is a Psycho-utopian. Keep dreaming, Steven.
