A moral order of free persons rejects appeal to the natural authority of some people’s private judgments over those of others. A social morality that allows the (self-appointed?) “enlightened” to make moral demands on others that as free and equal moral persons those others cannot see reason to acknowledge is authoritarian. Just as authoritarians in politics hold that they should rule over others who are too unenlightened or corrupt to see the wisdom of their laws, so too do these “enlightened” moralists hold up their “right reasoning” about morality as the standard that warrants their demands about how others should live, even when those others, exercising their rational moral autonomy, cannot endorse the imperatives to which they are subject.
