To apply this view, suppose George says, “Bill knows that his car is in the driveway”, while Barry says, “Bill doesn’t know that his car is in the driveway”. According to the relativist, the assessment of the truth-values of Bill’s and Barry’s statements depends also on the specification of some epistemic standard. For the truth-relativist, the standard will be the operative standard in the context of assessment. George’s utterance may be true (and Barry’s false) relative to a context of assessment in which ordinary “low” standards are in place, whereas Barry’s may be true (and George’s false) relative to a context of assessment in which high “Cartesian” standards are in place. See Stanley (2005: ch. 7) for a detailed criticism of this position, though see also MacFarlane (2014: §8.5 for a reply). See also Richard (2004), for another version of truth-relativism for knowledge attributions. In MacFarlane’s more recent (2014) defense of a truth-relativist semantics for “knows”, the context of assessment is taken to fix which alternatives count as relevant. See, however, Carter 2015 for an argument that MacFarlane’s more recent view generates counterintuitive results in cases of environmental epistemic luck (e.g., barn façade-style cases) and normative defeaters.
