Autonomy, Understanding, and Moral Disagreement

Should the existence of moral disagreement reduce one’s confidence in one’s moral judgments? Many have claimed that it should not. They claim that we should be morally self-sufficient: that one’s moral judgment and moral confidence ought to be determined entirely one’s own reasoning. Others’ moral beliefs ought not impact one’s own in any way. I claim that moral self-sufficiency is wrong. Moral self-sufficiency ignores the degree to which moral judgment is a fallible cognitive process like all the rest. In this paper, I take up two possible routes to moral self-sufficiency.
