Are all instances of the T-schema assertable? I argue that they are not. The reason is the presence of conventional implicature in a language. Conventional implicature is meant to be a component of the rule-based content that a sentence can have, but it makes no contribution to the sentence's truth-conditions. One might think that a conventional implicature is like a force operator. But it is not, since it can enter into the scope of logical operators. It follows that the semantic content of a sentence is not given simply by its truth-conditional content. So not all instances of the T-schema are assertable in the relevant sense. Consequently, there is a strong case to be made against truth-conditional semantics of the disquotational variety and deflationism about truth.

We review Potts’ influential book on the semantics of conventional implicature (CI), offering an explication of his technical apparatus and drawing out the proposal’s implications, focusing on the class of CIs he calls supplements. While we applaud many facets of this work, we argue that careful considerations of the pragmatics of CIs will be required in order to yield an empirically and explanatorily adequate account.

I argue for a subsumption of any version of Grice’s first quantity maxim posited to underlie scalar implicature, by developing the idea of implicature recovery as a kind of explanatory inference, as e.g. in science. I take the applicable model to be contrastive explanation, while following van Fraassen’s analysis of explanation as an answer to a why-question. A scalar implicature is embedded in such an answer, one that meets two probabilistic constraints: the probability of the answer, and ‘favoring’. I argue that besides having application at large, outside of linguistic interpretation, these constraints largely account not only for implicatures based on strength order, logical and otherwise, but also for unordered cases. I thus suggest that Grice’s maxim and its descendants are expressions of general explanatory constraints, as they happen to be manifested in this particular explanatory task. I conclude by briefly discussing how I accordingly view Grice’s system outside of scalar implicature.

H. P. Grice first presented his theory of conversational implicature in “Logic and Conversation.” This theory is comprised of conversational maxims that are based on the Cooperative Principle. Since then, it has become the default theory of implicature in pragmatics. This theory, however, is deeply flawed. Asa Kasher and Wayne Davis present alternative models for conversational implicature, but they both also have shortcomings in their theories. This work attempts to reconcile the Gicean theory of implicature with Kasher’s rationality based theory, and Davis’ theory of implicatures as conventions. The theory presented here creates conversational kinds to distinguish between cooperative conversation and non-cooperative conversation. Conversational implicature is convention based, but the conversational maxims are retained for cooperative conversational kinds. Thus, maxim violations end up as conversational cues informing participants that irrational statements may be better understood within a conventional framework. This provides for the shortcomings of the earlier works, and has greater explanatory power.

The history of conventional implicatures is rocky, their current status uncertain. So it seems wise to return to their source and start afresh, with an open-minded reading of the original definition (Grice 1975) and an eye open for novel factual support. Suppose the textbook examples (therefore, even, but and its synonyms) disappeared. Where would conventional implicatures be then? This book’s primary descriptive claim is that they would still enjoy widespread factual support. I match this with a theoretical proposal: if we move just a few years forward from the genesis of CIs, we find in Karttunen and Peters’ (1979) multidimensional semantics the basis for an ideal description logic.

Conversational implicatures are easy to grasp for the most part. But it is another matter to give a rational reconstruction of how they are grasped. We argue that Grice's attempt to do this fails. We distinguish two sorts of cases: (1) those in which we grasp the implicature by asking ourselves what would the speaker have to believe given that what he said is such as is required by the talk exchange; (2) those in which we grasp the implicature by asking ourselves why it is that what the speaker said is so obviously not such as is required by the talk exchange. We argue that Grice's account does not fit those cases falling under (2).

I’ve known about conversational implicature a lot longer than I’ve known Larry. In 1967 I read Grice’s “Logical and Conversation” in mimeograph, shortly after his William James lectures, and I read its precursor “(Implication),” section III of “The Causal Theory of Perception”, well before that. And I’ve thought, read, and written about implicature off and on ever since. Nevertheless, I know a lot less about it than Larry does, and that’s not even taking into account everything he has uncovered about what was said on the subject long before Grice, even centuries before. So, now that I’ve betrayed my ignorance, I’ll display my insolence. I’m going to identify the most pervasive and pernicious misconceptions about implicature that I’ve noticed over the years.

[First Paragraph] Unlike so many other distinctions in philosophy, H P Grice's distinction between what is said and what is implicated has an immediate appeal: undergraduate students readily grasp that one who says 'someone shot my parents' has merely implicated rather than said that he was not the shooter [2]. It seems to capture things that we all really pay attention to in everyday conversation'this is why there are so many people whose entire sense of humour consists of deliberately ignoring implicatures. ('Can you pass the salt?' 'Yes.') Unsurprisingly, it was quickly picked up and put to a wide variety of uses in not only in philosophy but also in linguistics and psychology. What is surprising, however, is that upon close inspection Grice's conception of implicature turns out to be very different from those at work in the literature which has grown out of his original discussion. This would not be much of a criticism of this literature were it not for the fact that discussions of implicature explicitly claim to be using Grice's notion, not some other one inspired by him (generally going so far as to quote one of Grice's characterisations of implicature). This still would not be terribly interesting if the notion Grice was actually carving out had little theoretical or practical utility. But I will argue here that Grice's own notion of implicature, one quite different from the ones most of us have come to work with, is in fact far more interesting and subtle than that which has been attributed to him.

Grice’s distinction between what is said and what is implicated has greatly clarified our understanding of the boundary between semantics and pragmatics. Although border disputes still arise and there are certain difficulties with the distinction itself (see the end of §1), it is generally understood that what is said falls on the semantic side and what is implicated on the pragmatic side. But this applies only to what is..

GRICE, H. PAUL (1913-1988), English philosopher, is best known for his contributions to the theory of meaning and communication. This work (collected in Grice 1989) has had lasting importance for philosophy and linguistics, with implications for cognitive science generally. His three most influential contributions concern the nature of communication, the distinction betwen speaker's meaning and linguistic meaning, and the phenomenon of conversational implicature.
