A Tension in Some Non-Naturalistic Explanations of Moral Truths
A Tension in Some Non-Naturalistic Explanations of Moral Truths

Summary/Abstract: Recently, there has been some excitement about the potential explanatory payoffs the newish metaphysical notion of grounding seems to have for metaethical non-naturalism. There has also been a recent upsurge in the debate about whether non-naturalism is implausibly committed to some acts being wrong because of some sui generis piece of ontology. It has, in response, been claimed that once we have a clear enough picture of the grounding role of moral laws on non-naturalism, this is not (objectionably) so. This move, I argue, is inconsistent with certain constraints on what non-naturalist-friendly moral laws must be for them to do the explanatory work non-naturalism requires of them elsewhere. In other words, there is tension between the grounding reply to the supervenience objection and the grounding structure implied by some responses to the normative objection.
