Epistemic contextualism in the style of Lewis (1996) maintains that ascriptions of knowledge to a subject vary in truth with the alternatives that can be eliminated by the subject’s evidence in a context. Schaffer (2004, 2005, 2007, 2008, 2015), Schaffer and Knobe (2012), and Schaffer and Szabo ́ (2014) hold that the question under discussion or QUD always determines these alternatives in a context. This paper shows that the QUD does not perform such a role for "know" and uses this (...) result to draw a few lessons about the metasemantics of context- sensitivity. (shrink)

Conversational contextualists claim that the truth-conditions of knowledge claims depend upon the dynamics of the conversation in which the knowledge claim is made. However, they have failed to appreciate the ways in which conversational dynamics are influenced by unjust distributions of power. What would the implications be for conversational contextualism if its proponents were not guilty of this oversight? I ask this question for Blome-Tillmann’s presuppositional epistemic contextualism (PEC), perhaps the most sophisticated form of conversational contextualism. The investigation turns up (...) a host of counterintuitive implications of PEC that count against it. I suggest placing moral constraints on conversational dynamics as a way of revising PEC in order to avoid the identified counterintuitive implications. (shrink)
