 What alternative foundations could legal moralism have if Devlin’s brand of moral relativism is to be rejected? In the light of Devlin’s stress on wrongdoing as a prima facie ground for legal coercion, one possibility might be an ethics of prima facie duty associated with W.D Ross (Ross 1930; Skelton 2012). And of course, any of the other numerous theories of what makes wrong action wrong—consequentialist, Kantian, natural law, rights-based, virtue ethics—could potentially form such a foundation (Timmons  2013).[10]  Michael Moore combines his legal moralism with a strong version of metaphysical realism (Moore 1997). Presumably, however, such strong metaethical commitments can be bracketed for the more specific questions raised by legal moralism. Jeremy Waldron for example suggests that an anti-realist or quasi-realist view, positing moral truth, albeit based ultimately on subjective sources “inside our own attitudes, desires, and natures”, could serve as well as an out-and-out realist view of Moore’s variety (Waldron 1999: 171). Again, while a legal moralist must surely reject a “vulgar” relativist view of Devlin’s stripe, it may not follow that a more sophisticated moral relativist grounding for legal moralism could not be attempted (Wong 2006; Rovane 2013; Velleman 2015; cf. Fricker 2013). Indeed Duff’s legal moralism is alleged by others to contain moral relativist commitments, a claim he himself rejects (Moore 2014: 199; Tadros 2016a: 121–128; Duff 2018: 232)
