According to the dominant position among philosophers of language today, we can legitimately ascribe determinate contents (such as truth-conditions) to natural language sentences, independently of what the speaker actually means. This view contrasts with that held by ordinary language philosophers fifty years ago: according to them, speech acts, not sentences, are the primary bearers of content. François Recanati argues for the relevance of this controversy to the current debate about semantics and pragmatics. Is 'what is said' (as opposed to merely implied) determined by linguistic conventions, or is it an aspect of 'speaker's meaning'? Do we need pragmatics to fix truth-conditions? What is 'literal meaning'? To what extent is semantic composition a creative process? How pervasive is context-sensitivity? Recanati provides an original and insightful defence of 'contextualism', and offers an informed survey of the spectrum of positions held by linguists and philosophers working at the semantics/pragmatics interface.

In my commentary on Herman Cappelen and Ernie Lepore’s aptly titled book, Insensitive Semantics, I stake out a middle ground between their version of Semantic Minimalism and Contextualism. My kind of Semantic Minimalism does without the “minimal propositions” posited by C&L. It allows that some sentences do not express propositions, even relative to contexts. Instead, they are semantically incomplete. It is not a form of contextualism, since being semantically incomplete is not a way of being context-sensitive. In their reply to my commentary, C&L seem to miss this point. Exaggerating the force of their slippery slope argument, they continue to suppose that contextualism is the only alternative to their version of minimalism. They contend that I haven’t replied to their central criticism, but in fact they haven’t replied to mine.

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.

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.

Philosophers on all sides of the contextualism debates have had an overly narrow conception of what semantic context sensitivity could be. They have conflated context sensitivity (dependence of truth or extension on features of context) with indexicality (dependence of content on features of context). As a result of this conflation, proponents of contextualism have taken arguments that establish only context sensitivity to establish indexicality, while opponents of contextualism have taken arguments against indexicality to be arguments against context sensitivity. Once these concepts are carefully pulled apart, it becomes clear that there is conceptual space in semantic theory for nonindexical forms of contextualism that have many advantages over the usual indexical forms.

Semantic minimalism is an attempt to answer two questions: ‘what counts as semantic content?’ and ‘what work does semantic content do?’. The answer the theory gives to both these questions is minimal (hence the name): first, semantic content is exhausted by the contributions made by the syntactic constituents of a sentence together with their mode of composition. Second the role played by this kind of content is much more constrained than is often supposed. With respect to the first question, semantic minimalism holds that content is entirely determined by syntax – there is nothing to be had ‘for free’, as it were, at the semantic level. Specifically, minimalism holds that it is not possible for features of the context of utterance to permeate semantic content unless their presence is demanded by something at the syntactic level. Furthermore, the syntactic elements which can trigger pragmatic intrusion are themselves limited to unarguably contextsensitive elements, such as words like ‘here’ and ‘now’. (Thus minimalism is not the thesis that semantic content is context-invariant, but that contextual infiltration of semantics is very limited.) So take utterances of the following sentences.

Insensitive Semantics is mainly a protracted assault on semantic Contextualism, both moderate and radical. Cappelen and Lepore argue that Moderate Contextualism leads inevitably, like marijuana to heroin or masturbation to blindness, to Radical Contextualism and in turn that Radical Contextualism is misguided. Assuming that the only alternative to Contextualism is their Semantic Minimalism, they think they’ve given an indirect argument for it. But they overlook a third view, one that splits the difference between the other two. Like Contextualism it rejects Propositionalism, the conservative dogma that every indexicalfree declarative sentence expresses a proposition. Unlike Contextualism, it does not invoke context to fill semantic gaps and, indeed, denies that filling those gaps is a semantic matter. In rejecting Propositionalism, it is more radical, indeed, more minimalist than Cappelen and Lepore’s brand of Semantic Minimalism. It does not imagine that sentences that intuitively seem not to express propositions at least express “minimal propositions.” Radical Semantic Minimalism, or simply Radicalism, says that the sentences in question are semantically incomplete – their semantic contents are not propositions but merely “propositional radicals.”.

In _Insensitive Semantics_, Herman Cappelen and Ernie Lepore (C&L) defend Semantic Minimalism and Speech Act Pluralism. Semantic Minimalism concerns the effect of utterance context on _semantic_ content. It holds, in contrast to the views of a wide variety of linguists and philosophers of language, that this effect is limited to fixing the semantic value of the small number of expressions they argue are genuinely context- sensitive: uncontroversial indexicals, demonstratives, tense markers, and perhaps a few others. What’s more, according to C&L, once this context-sensitivity has been accounted for, a (disambiguated) sentence expresses a truth-evaluable proposition. Speech Act Pluralism concerns _speech act_ content: what a speaker says (asserts, claims, etc.) by a particular utterance of a sentence. Among its central claims are: first, that speech act content typically includes an indefinite range of propositions, as evidenced by the indefinite range of accurate indirect speech reports concerning a particular utterance (call this Basic Pluralism); and, second, that speakers do not have privileged access to what they say, nor must they believe what they sincerely say (call this the Controversial Aspect).¹.

No semantic theory is complete without an account of context sensitivity. But there is little agreement over its scope and limits even though everyone invokes intuition about an expression's behavior in context to determine its context sensitivity. Minimalists like Cappelen and Lepore identify a range of tests which isolate clear cases of context sensitive expressions, such as ‘I’, ‘here’, and ‘now’, to the exclusion of all others. Contextualists try to discredit the tests and supplant them with ones friendlier to their positions. In this paper we will explore and evaluate Cappelen and Hawthorne's recent attempts to discredit Cappelen and Lepore's tests and replace them with others. We will argue they have failed to provide sufficient reason to abandon minimalism. If we are right, minimalism about context sensitivity is still viable.

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. Precisely this is denied by Recanati. Not only is this “minimal proposition” not part of speech act content. The minimal proposition plays no..
