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.

In Insensitive Semantics (2004), we argue for two theses – Semantic Minimalism and Speech Act Pluralism. In this paper, we outline our defense against two objections often raised against Semantic Minimalism. To get to that defense, we first need some stage setting. To that end, we begin with five stage setting sections. These lead to the first objection, viz., that it might follow from our view that comparative adjectives are context insensitive. We defend our view against that objection (not, as you might expect, by denying that implication, but by endorsing it). Having done so, we address a second objection, viz., that Semantic Minimalism makes it difficult to see what role semantic content plays in communicative exchanges. We respond and end with a reversal, i.e., we argue that even though the second objection fails against us, it works against those who raise the objection. In particular, we show that Recanati ends up with a notion of communicated content that fails various tests for psychological reality.

"Semantic Minimalists" holds that there are virtually no semantically context sensitive expressions in English. In particular, they claim that the semantics for terms like "red", "tall", "ready", "every", or "know" are not (contrary to many popular semantic theories) context sensitive. While minimalism strikes many as obviously false, it will be argued here that the view is more plausible than commonly assumed if one accepts the 'normative' conception of the relation between meaning and use characteristic of the literature on semantic externalism.

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.

If you think that semantic minimalism is the only alternative to contextualism but you’d rather do without Cappelen and Lepore’s mysteriously minimal “propositions,” you can. You just have to recognize that being semantically incomplete does not make a sentence context-sensitive. You don’t have to go through the ritual of repeatedly incanting things like this: “John is ready” expresses the proposition that John is ready. Instead, you can opt for Radical Minimalism and suppose that “John is ready” and its ilk fall short of semantically expressing propositions – their semantic contents are propositional “radicals.” Now C&L think they’ve addressed Radical Minimalism and offered objections to it. So they find it strange and bizarre that I think they haven’t. In fact, they persist in confusing semantic incompleteness with context sensitivity. If they appreciated the difference, they might even welcome the opportunity to adopt a form of semantic minimalism that does without the minimal propositions that everyone but them find incredible (pun intended).

After discussing some difficulties that contextualism and minimalism face, this paper presents a new account of the linguistic exploitation of context, situationalism. Unlike the former accounts, situationalism captures the idea that the main intuitions underlying the debate concern not the identity of propositions expressed but rather how truth-values are situation-dependent. The truth-value of an utterance depends on the situation in which the proposition expressed is evaluated. Hence, like in minimalism, the proposition expressed can be truthevaluable without being enriched or expanded. Along with contextualism, it is argued that an utterance’s truth-value is context dependent. But, unlike contextualism and minimalism, situationalism embraces a form of relativism in so far as it maintains that semantic content must be evaluated vis-à-vis a given situation and, therefore, that a proposition cannot be said to be true/false eternally.

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.”.

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.
