The notion of implicature has been a matter of discussion since Grice put it forward. He proposed a schema to explain how implicatures are generated and inferred, but the key condition it contains has been surprisingly overlooked. Davis detected it and named it determinacy, though for him this requirement raises several problems that make the whole Gricean theory of implicature untenable. I claim that, although the determinacy condition is flawed, it still captures a crucial mechanism of how implicatures are interpreted. (...) I attempt to recover this requirement under the relevance theory approach and show that, unlike the determinacy condition, the strength condition does not face the problems Davis formulates. Keywords: implicature, determinacy, strength, Cooperative Principle, principle of relevance, Gricean theory, relevance theory. (shrink)

This essay offers a constructive criticism of Part I of Davis’ Meaning, Expression and Thought. After a brief exposition, in Sect. 2, of the main points of the theory that will concern us, I raise a challenge in Sect. 3 for the characterization of expression that is so central to his program. I argue first of all that a sincere expression of a thought, feeling, or mood shows it. Yet attention to this fact reveals that it does not go without (...) saying how it is possible to show such things as thoughts, feelings or moods; we need an account of how this is possible, and I offer a partial such account in Sect. 4. Second, much of the attraction of Davis’ program depends on its ability to explain how linguistic meaning can be arrived at without covertly presupposing linguistic conventions. This in turn depends, in Davis’ hands, upon the claim that it is possible to express any of a wide range of ideas in the absence of conventions. I argue in Sect. 5 that the account of showing at which we will by then have arrived makes clear that Davis needs, and lacks, an explanation of how it is possible to do this. (shrink)
