Abstract
Specific moral facts seem to be grounded in relevant natural facts, together with relevant moral principles. This picture—according to which moral principles play a role in grounding specific moral facts—is a very natural one, and it may be especially attractive to non-naturalist, robust realists. A recent challenge from Selim Berker threatens this picture, though. Moral principles themselves seem to incorporate grounding claims, and it’s not clear that this can be reconciled with according the principles a grounding role. This chapter responds to Berker’s Challenge, utilizing a grounding pluralism. In particular, it argues that distinguishing between normative and metaphysical grounding is the key to saving the natural picture. It also shows how such a distinction is one that you have a reason to endorse independently of this challenge, as it does important work elsewhere in moral philosophy.
