The relativist must plausibly take issue with (2) or (3), (or both). For an attempt to meet Evans’ challenge, MacFarlane has defended a way to effectively reject (2) via what Marques has called a “meet-the-challenge” norm of assertion (cf. MacFarlane 2003; though see also his 2014: ch. 5; cf., Stanley 2016: 181–2)—according to which (à la Brandom 1983), in asserting p one undertakes a commitment to either defending p or giving up p if the challenge cannot be met satisfactorily (see Kölbel (2004: 308) for some other discussions of this objection).
