Does morality require something that doesn't exist 'magic'

  error theorists point out that the social nature of morality requires one to act against one's self-interest while insisting on the categorical, inescapable, or overriding status of moral considerations: 

they argue that morality requires magic, then (rightly) claim that there is no such thing as magic. An alternate eudaimonist (the condition of human flourishing or of living well.) conception of morality is introduced which itself has an older provenance than the social point of view, dating to the ancient Greeks.
