This paper proposes a new analysis of indirect speech in the framework of game theory, social psychology, and evolutionary psychology. It builds on the theory of Grice, which tries to ground indirect speech in pure rationality (the demands of e‰cient communication between two cooperating agents) and on the Politeness Theory of Brown and Levinson, who proposed that people cooperate not just in exchanging data but in saving face (both the speaker’s and the hearer’s). I suggest that these theories need to (...) be supplemented because they assume that people in conversation always cooperate. A reflection on how a pair of talkers may have goals that conflict as well as coincide requires an examination of the game-theoretic logic of plausible denial, both in legal contexts, where people’s words may be held against them, and in everyday life, where the sanctions are social rather than judicial. This in turn requires a theory of the distinct kinds of relationships that make up human social life, a consideration of a new role for common knowledge in the use of indirect speech, and ultimately the paradox of rational ignorance, where we choose not to know something relevant to our interests.

It is widely accepted that there is a distinction to be made between the explicit content and the implicit import of an utterance. There is much less agreement about the precise nature of this distinction, how it is to be drawn, and whether any such two-way distinction can do justice to the levels and kinds of meaning involved in utterance interpretation. Grice’s distinction between what is said by an utterance and what is implicated is probably the best known instantiation of (...) the explicit/implicit distinction. His distinction, along with many of its post-Gricean heirs, is closely entwined with another distinction: that between semantics and pragmatics. Indeed, on some construals they are seen as essentially one and the same; “what is said” is equated with the truthconditional content of the utterance which in turn is equated with (context-relative) sentence meaning, leaving implicatures (conventional and conversational) as the sole domain of pragmatics.

1. Implicature: some basic oppositions IMPLICATURE is a component of speaker meaning that constitutes an aspect of what is meant in a speaker’s utterance without being part of what is said. What a speaker intends to communicate is characteristically far richer than what she directly expresses; linguistic meaning radically underdetermines the message conveyed and understood. Speaker S tacitly exploits pragmatic principles to bridge this gap and counts on hearer H to invoke the same principles for the purposes of utterance interpretation. (...) The contrast between the said and the meant, and derivatively between the said and the implicated (the meant-but-unsaid), dates back to the fourth century rhetoricians Servius and Donatus, who characterized litotes—the figure of pragmatic understatement—as a figure in which we say less but mean more (“minus dicimus et plus significamus”; see Hoffmann 1987 and Horn 1991a for discussion). In the classical Gricean model, the bridge from what is said (the literal content of the uttered sentence, computed directly from its grammatical structure with the reference of indexicals resolved) to what is communicated is constructed through implicature. As an aspect of speaker meaning, implicatures are by definition distinct from the non-logical inferences that the hearer draws; it is a category mistake to attribute implicatures either to hearers or to sentences (e.g. P and Q) and subsentential expressions (e.g. some). But we can systematically (at least for generalized implicatures; see below) correlate the speaker’s intention to implicate q (in uttering p in context C), the expression p that carries the implicature in C, and the inference of q induced by the speaker’s utterance of p in C.
