Deirdre Wilson, & Dan Sperber. 2002. Truthfulness and relevance. Mind 111, 583.

Abstract: This paper questions the widespread view that verbal communication is governed by a maxim, norm or convention of literal truthfulness. Pragmatic frameworks based on this view must explain the common occurrence and acceptability of metaphor, hyperbole and loose talk. We argue against existing explanations of these phenomena and provide and alternative account, based on the assumption that verbal communication is governed not by expectations of truthfulness but by expectations of relevance, which are raised by literal, loose and metaphorical talk alike. Sample analyses are provided, and some consequences of this alternative account are explored.
