According to a view widely held by epistemic contextualists, the truth conditions of a knowledge claim depend on features of the context such as the presuppositions, interests and purposes of the conversational participants. Against this view, I defend an intentionalist account, according to which the truth conditions of a knowledge attribution are determined by the speaker’s intention. I show that an intentionalist version of contextualism has several advantages over its more widely accepted rival account.

The paper explicates a new way to model the context-sensitivity of 'knows', namely a way that suggests a close connection between the content of 'knows' in a context C and what is pragmatically presupposed in C. After explicating my new approach in the first half of the paper and arguing that it is explanatorily superior to standard accounts of epistemic contextualism, the paper points, in its second half, to some interesting new features of the emerging account, such as its compatibility with the intuitions of Moorean dogmatists. Finally, the paper shows that the account defended is not subject to the most prominent and familiar philosophical objections to epistemic contextualism discussed in the recent literature.

A very simple contextualist treatment of a sentence containing an epistemic modal, e.g. a might be F, is that it is true iff for all the contextually salient community knows, a is F. It is widely agreed that the simple theory will not work in some cases, but the counterexamples produced so far seem amenable to a more complicated contextualist theory. We argue, however, that no contextualist theory can capture the evaluations speakers naturally make of sentences containing epistemic modals. If we want to respect these evaluations, our best option is a relativist theory of epistemic modals. On a relativist theory, an utterance of a might be F can be true relative to one context of evaluation and false relative to another. We argue that such a theory does better than any rival approach at capturing all the behaviour of epistemic modals.

The paper is concerned with the semantics of knowledge attributions(K-claims, for short) and proposes a position holding that K-claims are contextsensitive that differs from extant views on the market. First I lay down the data a semantic theory for K-claims needs to explain. Next I present and assess three views purporting to give the semantics for K-claims: contextualism, subject-sensitive invariantism and relativism. All three views are found wanting with respect to their accounting for the data. I then propose a hybrid view according to which the relevant epistemic standards for evaluating K-claims are neither those at the context of the subject (subject-sensitive invariantism), nor those at the context of the assessor (relativism), but it is itself an open matter. However, given that we need a principled way of deciding which epistemic standards are the relevant ones, I provide a principle according to which the relevant standards are those that are the highest between those at the context of the subject and those at the context of the assessor/attributor. In the end I consider some objections to the view and offer some answers.

Contextualism in epistemology is the doctrine that the proposition expressed by a knowledge attribution relative to a context is determined in part by the standards of justification salient in that context. The (non-skeptical) contextualist allows that in some context c, a speaker may truly attribute knowledge at a time of a proposition p to Hannah, despite her possession of only weak inductive evidence for the truth of that proposition. Relative to another context, someone may make the very same knowledge attribution to Hannah, yet be speaking falsely, because the epistemic standards in that context are higher. The reason this is possible, according to the contextualist, is that the two knowledge attributions express different propositions.

Conversational contextualism in epistemology is characterized by four main theses: 1. the indexicality of knowledge claims thesis; 2. the attributor contextualism thesis; 3. the conversational contextualism thesis, and 4. the main thesis of contextualism according to which a knowledge claim can be true in one context and false in another context in which more stringent standards for knowledge are operant. It is argued that these theses taken together generate problems for contextualism. In particular, it is shown that there is no context in which the contextualist can truthfully claim to know her theory is true. Since these results were obtained only with principles the contextualist cannot give up—like the principle of epistemic closure and the principle that knowledge implies truth—it seems that contextualism is in need of a thoroughgoing revision if it is to become a successful epistemic theory.

According to Antonia Barkes version of contextualism, epistemic contextualism, a context is defined by a method and its associated assumptions. The subject has to make the assumption that the method is adequate or reliable and that good working conditions hold in order to arrive at knowledge by employing the method. I will criticize Barkes claim that epistemic contextualism can provide a more satisfactory explanation or motivation for context shifts than conversational contextualism (in particular, David Lewiss contextualism). Two more points of criticizm will be presented, which are meant to show that epistemic contextualism presupposes epistemic internalism, and that (epistemic) contextualism leads to an implausible view about which parameters the special achievement that is constitutive of knowledge depends on. I suggest that, contra (epistemic) contextualism, knowledge is a more robust phenomenon that does not depend on whether anyone calls into question any assumptions or raises skeptical doubts in conversation or in his or her mind (as, for example, Fred Dretskes account says). I indicate how this can be reconciled with the phenomenon that knowledge attributions are somewhat unstable and seemingly context-dependent.

In this paper I develop a version of contextualism that I call interests contextualism. Interests contextualism is the view that the truth-conditions of knowledge ascribing and denying sentences are partly determined by the ascriber’s interests and purposes. It therefore stands in opposition to the usual view on which the truth-conditions are partly determined by the ascriber’s conversational context. I give an argument against one particular implementation of the usual view, differentiate interests contextualism from other prominent versions of contextualism and argue that, unlike those versions, interests contextualism can mitigate against the epistemic descent objection put forward by Duncan Pritchard in his ‘Contextualism, Scepticism, and the Problem of Epistemic Descent’ (the objection is that, on the contextualist view, an ascriber of knowledge cannot, for some subject S and proposition p, properly ascribe knowledge that p to S if that ascriber has previously retracted an earlier ascription of knowledge that p to S).
