This paper introduces Paul Grice’s notion of conversational implicature. The basic ideas — the cooperative principle, the maxims of conversation, and the contrast between implicature and presupposition — make it clear that conversational implicature is a highly contextualized form of language use that has a lot in common with non-linguistic behavior. But what exactly is its role? We invite the ...

An implicature i that arises from an utterance U is cancelable if U is consistent with not i. If i is a cancelable implicature, then it is a conversational implicature. However, some particularized conversational implicatures (PCIs) cannot straightforwardly be canceled. Imagine that Mr. X is applying for a philosophy position and his teacher is writing him the following letter of recommendation:

Standard implementations of Grice’s theory of conversational implicature assume that the derivation an implicature always begins with a single proposition expressed by means of a sentence in a given context. Against this received view, I argue that, in at least three ways, implicatures are discourse-based rather than proposition-based. First, in some cases an implicature can only be derived fro...

beliefs explaining the role the first set of beliefs play in the speaker's plan. Pollack's idea of ascribing a set of additional beliefs based on the intentions contained in the recognised plan is similar to our idea of ascribing additional conversational goals to explain why a plan is apparently inefficient. However, her motivation is to show how mistaken beliefs in dialogue can be recognised ...

H. P. Grice pioneered the study of conversational logic and put forward classic theory Conversational Implicature Cooperative Principle. Completely adhering to Principle or deliberately violating it will lead Implicature. In The Great Gatsby, main characters, such as Gatsby Daisy, tactically violate abide by relevant maxims in their communication, thus generating expressing true feelings. At sa...
