 What’s more, the possibility of cultural diversity raises a troubling question for philosophers who want to establish normative claims on the basis of analyses of concepts, such as the concept of justification. Suppose, for example, that East Asian culture offers a different concept of justification than the one that is embedded in Western commonsense thought (assuming for sake of argument that there is a single concept of justification in each culture). In addition, suppose that East Asians employ different inferential practices than our own and that their practices do a fair job of conforming to their concept of justification and that ours do a fair job of conforming to our own. On what basis, then, are we to compare and evaluate these differing practices? Does it really make sense to say that ours are superior on the ground that they conform better to our concept of justification? Wouldn’t this just be a form of epistemic prejudice? After all, the question arises whether, given the two concepts of justification, ours is the one that ought to be used for performing normative epistemic evaluations (Stich 1990; for further discussion see Williamson 2005, Sosa 2009, Stich 2009, Weinberg, Nichols, &amp; Stich 2001, Weinberg et al. 2010).
