Essentialism and Nonnaturalist Normative Supervenience

In this essay I defend a kind of nonnatural- ist normative supervenience, grounded in the essences of things. Essentialist theories, in fact, give us the tools to treat the nexus of normative supervenience as a nexus of metaphysical necessity, holding between the normative and the natural. In this context, essentialist grounding provides an explanation of normative supervenience that allows us to keep together both supervenience and nonnaturalism. Moreover, to achieve this significant result, I do not make use of hybrid properties, which are both normative and nat- ural. Rather, I endeavour to show that the notion of hybrid property is based on an erroneous notion of grounding.
