Lying and falsely implicating

This paper analyses falsely implicating from the point of view of Gricean theory of implicature, focusing on the Story of the Mate and the Captain which is a classical example of lying while saying the truth. It is argued that the case of falsely implicating should be included within a general definition of lying. Whether Particularised Conversational Implicatures (PCI), as in the Story of the Mate and the Captain, and Generalised Conversational Implicatures (GCI) behave differently with regard to falsely implicating is discussed with reference to Levinson's theory of presumptive meaning [Levinson, Stephen C., 2000. Presumptive Meanings. The Theory of Generalised Conversational Implicature. MIT Press, Cambridge, Mass]. It turns out that, in contrast to PCIs, the case where the assertion is false and the implicature is true is not possible with GCIs. In addition, tautology and irony are analysed, and some repercussions on the speech act notion of lying are pointed out.
