I 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 HaidtWhile it is useful to rebut charges and get your arguments out in circulation, you have to understand that arguments and evidence have little impact on people as long as their feelings tilt them against you.
Jonathan HaidtMany species reciprocate, but only humans gossip, and much of what we gossip about is the vale of other people as partners for reciprocal relationships.
