 The general strategy just canvassed has two stages: the first stage carefully examines cases, and the second appeals to our more general understanding of the ethical. Both parts of the strategy can be useful in addressing the question of what the ethical supervenes on. For example,  Section 1.1  appealed to possible cases involving supernatural beings as part of an argument against the idea that the ethical supervenes on the natural. In terms of the first part of the strategy, this suggests that once we make salient the possibility of supernatural beings, ethical supervenience theses that posit a naturalistic base become more doubtful. In terms of the second part of the strategy, the same cases fit nicely with the Sidgwickian thesis: if an ethical claim were true in part because of some supernatural truth, it would thereby not be brutely true. As noted in  Section 1.1,  characterizing what the ethical supervenes on is an open challenge. This merely illustrates how the strategy can be applied to make progress on that challenge.
