We can tolerate great diversity in our aesthetic beliefs, but we can't tolerate much diversity in our moral beliefs.
Jonathan HaidtI think that moral philosophy is useful for framing questions, but terrible at answering them. I think moral psychology is booming right now, and we're making a lot of progress on understanding how we actually work, what our moral nature is.
Jonathan HaidtI think moral philosophy is speculation on how we ought to live together done by people who have very little clue how people work. So I think most moral philosophy is disconnected from the species that we happen to be. In fact, they like it that way. Many moral philosophers insist that morality grows out of our rationality, that it applies to any rational being anywhere in the universe, and that it is not based on contingent or coincidental facts about our evolution.
Jonathan HaidtSacredness binds people together, and then blinds them to the arbitrariness of the practice.
