 The attractions of moral non-objectivism are that it ticks a lot of boxes that its competitors fail to tick. Unlike noncognitivism or error theory, moral non-objectivism is a form of moral anti-realism that allows for the existence of moral beliefs, moral facts, and moral truth, and thus also potentially makes conceptual space for such things as moral progress and moral knowledge. Unlike moral realism, by making the moral facts depend on us, moral non-objectivism seems to have an easier time accounting for a moral ontology that is both naturalistic and normative.
