I look upon it as a Point of Morality, to be obliged by those who endeavour to oblige me.
– Richard Steele
I’m not saying that atheists can’t act morally or have moral knowledge. But when I ascribe virtue to an atheist, it’s as a theist who sees the atheist as conforming to objective moral values. The atheist, by contrast, has no such basis for morality. And yet all moral judgments require a basis for morality, some standard of right and wrong.
– William A. Dembski
