I define 'skim semantics' to be a Davidson-style truth-conditional semantics combined with a variety of deflationism about truth. The expressive role of truth in truth-conditional semantics precludes at least some kinds of skim semantics; thus I reject the idea that the challenge to skim semantics derives solely from Davidson's explanatory ambitions, and in particular from the 'truth doctrine', the view that the concept of truth plays a central explanatory role in Davidsonian theories of meaning for a language. The fate of skim semantics is not determined by the fate of the truth doctrine, so rejecting the truth doctrine does not in itself open the way to skim semantics. I establish my thesis by showing that some recently proposed versions of skim semantics fail because of truth's expressive role. I also discuss the conditions that might permit skim semantics.

David’s epistemic understanding of two-dimensional semantics has these two features. First, although he considers at least two construals of epistemically possible worlds, on one of them they are centered metaphysically possible worlds. Second, David intends epistemic two-dimensional semantics to yield a theory of propositional-attitude content, as well as having application to the semantics of natural language expressions. These two features come together in David’s “The Components of Content,” where he deploys the apparatus of epistemic two-dimensional semantics to provide an account of propositional-attitude content, and where, for reasons of simplicity and familiarity, epistemically possible worlds are taken to be centered metaphysically possible worlds. My talk is about this account of content.

Epistemic modal operators give rise to something very like, but also very unlike, Moore's paradox. I set out the puzzling phenomena, explain why a standard relational semantics for these operators cannot handle them, and recommend an alternative semantics. A pragmatics appropriate to the semantics is developed and interactions between the semantics, the pragmatics, and the definition of consequence are investigated. The semantics is then extended to probability operators. Some problems and prospects for probabilistic representations of content and context are explored.

Two opposing tendencies in the philosophy of language go by the names of ‘referentialism’ and ‘inferentialism’ respectively. In the crudest version of the contrast, the referentialist account of meaning gives centre stage to the referential semantics for a language, which is then used to explain the inference rules for the language, perhaps as those which preserve truth on that semantics (since a referential semantics for a language determines the truth-conditions of its sentences). By contrast, the inferentialist account of meaning gives centre stage to the inference rules for the language, which are then used to explain its referential semantics, perhaps as the semantics on which the rules preserve truth. On pain of circularity, we cannot combine both directions of explanation.
