Disimplicature

Speranza

Many recent definitions of lying, alla Grice, are based on the notion of what is said. 

Grice argues that says-based definitions of lying cannot account for lies involving non-literal speech, such as metaphor, hyperbole, loose use or irony. It proposes that lies should instead be defined in terms of assertion, where what is asserted need not coincide with what is said. And it points to possible implications this outcome might have for the ethics of lying.
