If well-informed, honest and intelligent people are unable to resolve conflicts of opinion, we should, some relativists argue, accept that all parties to such disputes could be right and their conflicting positions have equal claims to truth, each according to their own perspective or point of view. Their disagreement is faultless (Kölbel 2004; Brogaard 2007; Hales 2014). Many relativistically inclined philosophers, (e.g., Max Kölbel (2004), Wright (2006) and John MacFarlane with terminological qualification (2014: 133–136)) see the presence of faultless disagreements as central to motivating and justifying relativism. The anti-relativists counter that the very notion of a “faultless” disagreement is incompatible with our common understanding of what it means to disagree. It is a hallmark of disagreement, as commonly understood, that the parties involved find fault with the other sides’ views. When people disagree at least one of them is making a mistake or is failing to believe what he or she ought to believe given his or her cognitive aims. Relativism accordingly offers a revisionary account of what it means to disagree (e.g., MacFarlane 2007, 2014; see §5 where the point has been discussed in some detail); but it is not clear if the account can explain what is left of a disagreement to preserve once we allow that both parties to a disagreement could be right (Carter 2013; Dreier 2009).
