 Suppose that we rejected this idea in an especially radical way, insisting instead on the reverse order of metaphysical explanation everywhere. The nature of every property, we might say, is wholly grounded in some relevant subset of the true propositions. Provided that we can recover the idea of metaphysical explanation within this framework, we will be able to isolate the set of propositions that state metaphysically unexplained necessary connections. And it is natural to think that the brute necessities worry could be expressed within this framework as objecting to accepting such propositions. The problem is that fundamental normative principles, as invoked in the ‘ethical explanation’ strategy, would seem to be of exactly the objectionable sort.
