 The appeal to fundamental laws may seem to raise the same concerns that a brute supervenience relation did, however: Why is there a metaphysical law linking these distinct properties? The contrast with essentialist explanations is striking: in the latter case, facts about the natures of the related properties explain the links between them. However, some have argued that metaphysical grounding relations are either commonly, or even universally, law-mediated (e.g. Kment 2014, §6.2.3; Wilsch 2015). For a taste of the currently flowering literature on the explanatory role of ethical laws or principles, see (Eliot 2014; Scanlon 2014, Ch. 2; Schroeder 2014; Skarsaune 2015; §7; Rosen 2017a; 2017c; Berker forthcoming; and Morton forthcoming).
