Basic to Robert Brandom’s project in Making It Explicit is the demarcation of singular terms according to the structure of their inferential roles---rather than, as is usual, according to the kinds of things they purport to denote. But the demarcational effort founders on the need to distinguish extensional and nonextensional occurrences of expressions in terms of inferential roles; the closest that an inferentialist can come to drawing that distinction is to discern degrees of extensionality, and that is not close enough. The general moral applies as well to “two factor” theories of content: the notion of inferential role lacks the independence from the notion of denotation that many proponents of such theories have attributed to it.

It’s been, for some time now, a pet thesis of ours that compositionality is the key constraint on theories of linguistic content. On the one hand, we’re convinced by the usual arguments that the compositionality of natural languages1 explains how L-speakers can understand any of the indefinitely many expressions that belong to L.2 And, on the other hand, we claim that compositionality excludes all “pragmatist”3 accounts of content; hence, practically all of the theories of meaning that have been floated by philosophers and cognitive scientists for the last fifty years or so. A number of objections to our claim have been suggested to us, but none that we find persuasive (see, for example, the discussions of the “uniformity principle” and of “reverse compositionality” in Fodor and Lepore 2002). These objections have a common thread: they all grant that mental and linguistic content are compositional but challenge the thesis that compositionality is incompatible with semantic pragmatism. In this paper, we want to consider an objection of a fundamentally different kind, namely, that it doesn’t matter whether compositionality excludes semantic pragmatism because compositionality isn’t true; the content of an expression supervenes not on its linguistic structure4 alone but on its linguistic structure together with the context of its tokening.5..

Fodor & Lepore (2001) and Williamson (2003) attack the inferentialist account of concept possession according to which possessing or understanding a concept requires endorsing the inference patterns constitutive of its content. I show that Fodor & Lepore's concern – that the conception places an exorbitant epistemological demands on possessors of a concept – is met by Brandom's tolerance of materially bad nonconservative inferences. Such inferences themselves, as Williamson argues, present difficulties for the 'understanding as endorsement' conception. I show that, properly understood, Brandom's broad conception of inferential role, which encompasses social-perspectival inferential connections, has the resources to respond to Willianson's challenge.

Inferentialism, which I am going to present in detail in the following sections, is the view that meanings are, roughly, roles that are acquired by types of sounds and inscriptions in virtue of their being treated according to rules of our language games, roughly in the sense in which wooden pieces acquire certain roles by being treated according the rules of chess. The most important consequences are that (i) a meaning is not an object labeled (stood for, represented ...) by an expression; and that (ii) meaning is normative in the sense that to say that an expression means thus and so is to say that it should be used so and so. The founding father of inferentialism is Brandom (1994; 2000). (However, nothing in this paper hinges on the fact that the version of inferentialism defended here is identical with Brandom's). This position provokes two kinds of objections. First there are general objections towards the very normativity of meaning, which do not target especially inferentialism; these I have addressed elsewhere 1. Besides this, there are objection targeted more specifically at inferentialism. Probably the most discussed specimen of such objections is the objection - repeatedly raised especially by Jerry Fodor and Ernest LePore and others - to the effect that though meanings should be compositional, the compositionality of inferential roles is unattainable. This is the kind of objection I am going to deal with here 2. (Hand in hand with this objection then go various allegations of circularity of inferentialism, which we will also discuss.) To do this, I will exploit the long-standing comparison of language to chess, as it seems particularly helpful for making the inferentialist account of language plausible3. This comparison, to be sure, has its limits beyond which it may become severely misleading; but as long as we keep them in mind, it can serve us very well.

Ernie Lepore and Jerry Fodor have published a series of original and controversial essays on issues relating to compositionality in language and mind; they have...

I propose a version of inferential role theory which says that having a concept is having the disposition to draw most of the inferences based on the stereotypical features associated with this concept. I defend this view against Fodor and Lepore.
