I show that an overlooked feature of our moral life—moral status—provides a route to vindicating naturalist moral realism in much the same way that the Humean theory of motivation and judgment internalism are used to undermine it. Moral status presents two explanatory burdens for metaethical views. First, a given view must provide an ecumenical explanation of moral status, which does not depend on the truth of its metaethical claims (say, that there are mind-independent facts about moral status). Second, its explanation must be consistent with persistent normative ethical disagreement about what constitutes moral status. I conclude that naturalist moral realism succeeds, while quasi-realism fails because it cannot meet the latter requirement. This argument has three results: we have a new route for metaethical vindication more generally and for naturalist moral realism in particular; quasi-realism's plausibility is undermined by an inability to explain disagreement, but not for the familiar reasons.
