In this paper I consider the prospects for pluralism about knowledge, that is, the view that there is a plurality of knowledge relations. After a brief overview of some views that entail a sort of pluralism about knowledge, I focus on a particular kind of knowledge pluralism I call standards pluralism. Put roughly, standards pluralism is the view that one never knows anything simpliciter. Rather, one knows by this-or-that epistemic standard. Because there is a plurality of epistemic standards, there is (...) a plurality of knowledge relations. In §1 I argue that one can construct an impressive case for standards pluralism. In §2 I clarify the relationship between standards pluralism, epistemic contextualism and epistemic relativism. In §3 I argue that standards pluralism faces a serious objection. The gist of the objection is that standards pluralism is incompatible with plausible claims about the normative role of knowledge. In §4 I finish by sketching the form that a standards pluralist response to this objection might take. (shrink)

Keith DeRose defends contextualism: the view that the truth-conditions of knowledge ascriptions vary with the context of the ascriber. Mark Richard has criticised contextualism for being unable to vindicate intuitions about disagreement. To account for these intuitions, DeRose has proposed truth-conditions for “knows” called the Gap view. According to this view, knowledge ascriptions are true iff the epistemic standards of each conversational participant are met, false iff each participant's standards aren't met, and truth-valueless otherwise. An implication of the Gap view (...) is that people with divergent standards can enter conversations and thereby render knowledge claims gappy. We characterise this as a form of trolling. We argue that trolling results in unacceptably counterintuitive implications and that this constitutes a reductio against the Gap view. We also briefly explore the implications of trolling for other contextualist views about “knows,” as well as a broader class of context sensitive expressions. (shrink)

This paper defends a version of epistemic contextualism that accounts for the ordinary judgements and theoretical principles that motivate pragmatic encroachment. Adopting this contextualist view, we can avoid the counterintuitive consequences of pragmatic encroachment, while still preserving its attractive applications.

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)

The Argument from Principles, the primary motivation for impurism or pragmatic encroachment theories in epistemology, is often presented as an argument for everyone—an argument that proceeds from harmless premises about the nature of rationally permissible action to the surprising conclusion that one’s knowledge is partly determined by one’s practical situation. This paper argues that the Argument from Principles is far from neutral, as it presupposes the falsity of one of impurism’s main competitors: epistemic contextualism. As a consequence, hybrid positions combining (...) impurism and contextualism—positions that impurists have sometimes hinted at in the literature—are, while logically consistent, ill-motivated. Once the impurist embraces contextualism, the Argument from Principles can no longer get off the ground. The paper concludes that those who make use of the Argument from Principles are committed to an invariantist impurism and their case in support of impurism can only ever be as strong as their case against contextualism. Given recent contextualist work on the semantics of ‘knowledge’-attributions, this is likely to turn out problematic for the impurists. (shrink)
