Moral skepticism

This paper explores the landscape of moral skepticism by delineating three principal forms. First, noncognitivism denies that moral judgments express beliefs at all, rejecting their status as propositions. Second, error theory accepts that moral judgments are truth-apt but contends they are uniformly false. Third, justification skepticism allows moral beliefs may be true but holds that agents are never epistemically justified in believing them. These positions are systematically clarified and contrasted.
