 Particularized conversational implicatures have a wide range of applications that Grice himself illustrates: the informative use of tautologies, irony, metaphor, hyperbole, meiosis and, in principle, any kind of non-literal use that relies in special circumstances of the utterance can be explained in terms of them. But GCIs apply to philosophically more important issues, in particular, to what, according to the introduction to “Logic and Conversation”, was Grice’s most important motivation: the issue of the difference of meaning between logical constants of formal languages and their counterparts in natural languages, or the alleged meanings of verbs like ‘to look like,’ ‘to believe’ or ‘to know.’ GCIs are also at the heart of Grice’s Modified Occam’s Razor (“Senses are not to be multiplied beyond necessity,” Grice 1967b/1989, 47), which has served as a criterion for distinguishing semantic issues from pragmatic uses and for preferring, in general, an explanation in terms of implicatures rather than a semantic one that postulates ambiguity.
