The central issue of this essay is whether contextualism in epistemology is genuinely in conflict with recent claims that ‘know’ is not in fact a contextsensitive word. To address this question, I will first rehearse three key aims of contextualists and the broad strategy they adopt for achieving them. I then introduce two linguistic arguments to the effect that the lexical item ‘know’ is not context sensitive, one from Herman Cappelen and Ernie Lepore, one from Jason Stanley. I find these and related arguments quite compelling. In particular, I think Cappelen and Lepore (2003, 2005a) show pretty definitively that ‘know’ is not like ‘I’/‘here’/‘now’, and Stanley (2004) shows that ‘know’ is not like ‘tall’/‘rich’.1 One could try to find another model for ‘know’. Instead, I consider whether one can rescue ‘‘the spirit of contextualism in epistemology’’—that is, achieve its aims by deploying a strategy of appealing to speaker context—even while granting that ‘know’ isn’t a context-sensitive word at all. My conclusion, in a nutshell, is this: If there are pragmatic determinants of what is asserted/stated, and contextualism can overcome independent problems not having to do specifically with the context-sensitivity of the word ‘know’, then the spirit of contextualism can be salvaged. Even though, for reasons sketched by the aforementioned authors, ‘know’ doesn’t actually belong in the class of context-sensitive words.

Contextualist solutions to skeptical puzzles have recently been subjected to various criticisms. In this paper, I will defend contextualism against an objection prominently pressed by Stanley 2000. According to Stanley, contextualism in epistemology advances an empirically implausible hypothesis about the semantics of knowledge ascriptions in natural language. It is empirically implausible because it attributes to knowledge ascriptions a kind of semantic context-sensitivity that is wholly unlike any well- established type of semantic context-sensitivity in natural language.

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.

In the recent debate on the semantic/pragmatic divide, Herman Cappelen and Ernie Lepore (2005) on the one hand, and Fran¸ cois Recanati (2004) on the other, occupy almost diametrically opposed positions as regards the role of semantics for communication, while largely agreeing on important features of pragmatics. According to Cappelen and Lepore (CL), semantic context sensitivity of natural language sentences is restricted to what is determined by a particular minimal set of canonically context sensitive expressions. If you try to go beyond that set, as has often been done in recent semantic theories, to reach a position of moderate contextualism, your reasons will force you to the much more extreme position of radical contextualism. That is CL’s instability thesis. They argue for it by means of a number of examples intended to illustrate how you are off on a slippery slope if you admit any context sensitivity beyond the basic one. If radical contextualism is true, systematic semantics is not possible, since, according to CL, there cannot be any systematic theory of speech act content. The one exception is that whatever is said by the utterance of a sentence, its minimally context dependent content is part of it.

David Lewis, Stewart Cohen, and Keith DeRose have proposed that sentences of the form S knows P are indexical, and therefore differ in truth value from one context to another.1 On their indexical contextualism, the truth value of S knows P is determined by whether S meets the epistemic standards of the speakers context. I will not be concerned with relational forms of contextualism, according to which the truth value of S knows P is determined by the standards of the subject Ss context, regardless of the standards applying to the speaker making the knowledge claim. Relational contextualism is a form of normative relativism. Indexical contextualism is a semantic theory. When the subject is the speaker, as when S is the first person pronoun I, the two forms of contextualism coincide. But otherwise, they diverge. I critically examine the principal arguments for indexicalism, detail linguistic evidence against it, and suggest a pragmatic alternative.

Contextualism, in its standard form, is the view that the truth conditions of sentences of the form ‘S knows that P’ vary according to the context in which they are uttered. One possible objection to contextualism appeals to what Keith DeRose calls a warranted assertability maneuver (or WAM), according to which it is not our knowledge sentences themselves that have context-sensitive truth conditions, but what is pragmatically conveyed by the use of such sentences. Thus, proponents of WAMs argue, the context sensitivity of knowledge attributions is not a semantic phenomenon but a pragmatic one. I examine a number of WAMs and show that each (i) is seriously flawed, or (ii) undercuts standard contextualism if we hold a minimalist conception of semantic content. I propose an alternative form of contextualism that accommodates minimalism and is immune to the second type of WAM, and show that this new form of contextualism shares the virtues of standard contextualism.

I will begin with a brief presentation of C & H’s arguments against nonindexical contextualism, temporalism, and relativism. I will then offer a general argument against the monadic truth package. Finally, I will offer arguments in favor of nonindexical contextualism and temporalism.

Contextualism about vagueness (hereafter ‘Contextualism’) is the view that vagueness consists in a particular species of context-sensitivity and that properly accommodating this fact into our semantic theory will yield a plausible solution to the sorites paradox.[1],[2] But Contextualism, as many commentators have noted, faces the following immediate objection: if we hold the context fixed, vagueness still remains, therefore vagueness is not a species of context-sensitivity. Call this ‘the simple objection’.[3] Absent a convincing reply to the simple objection, Contextualism is in very bad shape. Oddly enough, defenders of Contextualism have said very little in reply. Proponents of the objection have tended to assume that this is because no reply is in the offing—the simple objection is taken to be unassailable. In this short paper, we sketch two replies to the simple objection which result in two very different kinds of Contextualism: Epistemicist Contextualism and Radical Contextualism. With these two theories in hand, the simple objection loses its force.

Abstract   MacFarlane distinguishes “context sensitivity” from “indexicality,” and argues that “nonindexical contextualism” has significant advantages over the standard indexical form. MacFarlane’s substantive thesis is that the extension of an expression may depend on an epistemic standard variable even though its content does not. Focusing on ‘knows,’ I will argue against the possibility of extension dependence without content dependence when factors such as meaning, time, and world are held constant, and show that MacFarlane’s nonindexical contextualism provides no advantages over indexical contextualism. The discussion will shed light on the definition of indexicals as well as the meaning of ‘knows,’ and highlight important constraints on the way meaning can be represented in semantics.

According to Semantic Minimalism, every use of "Chiara is tall" (fixing the girl and the time) semantically expresses the same proposition, the proposition that Chiara is (just plain) tall. Given standard assumptions, this proposition ought to have an intension (a function from possible worlds to truth values). However, speakers tend to reject questions that presuppose that it does. I suggest that semantic minimalists might address this problem by adopting a form of "nonindexical contextualism," according to which the proposition invariantly expressed by "Chiara is tall" does not have a context-invariant intension. Nonindexical contextualism provides an elegant explanation of what is wrong with "context-shifting arguments" and can be seen as a synthesis of the (partial) insights of semantic minimalists and radical contextualists.
