 For our purposes, the important point is that formalism offers an affirmative answer to the question we are discussing in this section, for it explains normativity on the basis of the logic and content of norms and rules that have currency in relevant social contexts (Tiffany 2007; Parfit 2011, II: 308–309). H.L.A. Hart arguably has a similar view about the normativity of law (1994: 257; see Copp 2019). If normative formalism is correct, then, there is a ready answer to Mackie’s argument from queerness. For, if formalism is correct, normativity is no more mysterious than facts about the rules of games or facts about social norms and social practices.
