 The first is the relative explanatory priority of the semantic properties of sentences, on the one hand, and subsentential expressions, on the other. It is natural for the classical semanticist to think that the representational relations between subsentential expressions and their semantic contents can be explained independently of the representational properties of sentences (i.e., their truth conditions); the latter can thus be explained in terms of the former. For the inferentialist, on the other hand, the semantic properties of sentences must come first, because inferential relations hold between sentences but not between subsentential expressions. (One cannot, for example, infer one name from another.) So the inferentialist will not explain the semantic properties of, for example, singular terms in terms of representational relations between those singular terms and items in the world; rather, she will explain what is distinctive of singular terms in terms of their role in certain kinds of inferences. (To see how this strategy might work, see Brandom 2000: Ch. 4.)
