Morality is a biological adaptation no less than are hands and feet and teeth . . . Considered as a rationally justifiable set of claims about an objective something, [ethics] is illusory. I appreciate that when somebody says, ‘Love thy neighbor as thyself,’ they think they are referring above and beyond themselves . . . Nevertheless, . . . such reference is truly without foundation. Morality is just an aid to survival and reproduction, and any deeper meaning is illusory . . .
