 Suppose that, necessarily, every possible ethical instantiation fact is grounded by the combination of a base fact and an ethical law, as in this example. Then, (i) this would provide a complete explanation for supervenience: this grounding structure would explain why the instantiation of ethical properties must covary with thew instantiation of base properties. And (ii) this might look like a promising explanation on behalf of the non-naturalist, since the ethical laws could be metaphysically fundamental ethical entities. If ethical laws such as the one mentioned here are metaphysically fundamental, then one might think that this would secure non-naturalism (For this reason, Gideon Rosen calls such metaphysically fundamental laws ‘Moorean connections’ (2010, §13).
