In this paper I develop an argument against a type of Non-Analytic Normative Naturalism. This argument, the Normative Property Dualism Argument, suggests that, if Non-Analytic Normative Naturalists posit that normative properties are identical to natural properties and that such identities are a posteriori, they will be forced to posit that these properties which are both normative and natural have higher-order normative properties of their own.

This article aims to contribute to the largely neglected issue of whether metaphysical grounding – the relation of one fact’s obtaining in virtue of the obtaining of some other (or others) – can be given a reductive account. I introduce the notion of metaphysically opaque grounding, a form of grounding which constitutes a less metaphysically intimate connection than in standard cases. I then argue that certain important and interesting views in metaphysics are committed to there being cases of opaque grounding (...) and demonstrate that four representative accounts of grounding available in the literature are unable to accommodate such cases. This is argued to constitute a problem for those accounts that is likely to extend to other possible reductive accounts of grounding that employ the popular strategy of explaining grounding in terms of other hyperintensional phenomena. Unless the reductionist is willing to opt for some sophisticated modalist account, the possibility of opaque grounding cases thus provides indirect support for primitivism about grounding, a view that has previously been widely embraced but rarely supported by argument.

I argue for the viability of one neglected way of developing supervenience-based objections to metaethical non-naturalism. This way goes through a principle known as ‘Hume’s Dictum’, according to which there are no necessary connections between distinct existences. I challenge several objections to the Hume’s Dictum-based argument. In the course of doing so, I formulate and motivate modest and precise versions of Hume’s Dictum, illustrate how arguments employing these principles might proceed, and argue that the Hume’s Dictum argument enjoys some advantages (...) relative to other supervenience-based objections to non-naturalism.
