Where do lmplicatures come from?

Abstract

There is trouble at the foundations of Grice's theory of conversational implicature, or so I shall argue. Grice's commentators seem to agree, and some of Grice's own remarks suggest, that every case of implicature is one in which ‘the speaker gets across more than he says…. ’ The problem is that there are cases in which nothing is said - in which case it is not clear that there is any vehicle by which the implicature might be carried, and consequently not clear that Grice's theory can account for the implicature which does appear to be carried.
