Figurative language? Or literal? Is there a difference?

The traditional position, both in philosophy and in linguistics – and indeed the everyday view – is that (1) there is a stable and unambiguous notion of literality, and (2) that there is a sharp distinction to be made between literal language, on the one hand, and non-literal or figurative language on the other. According to this view, while literal language is precise and lucid, figurative language is imprecise, and is largely the domain of poets and novelists. In his 1994 book The Poetics of Mind, cognitive psychologist and cognitive linguist Raymond Gibbs examined this issue. Based on a close examination of the key features that are held to distinguish literal and figurative language, and based on a wide-ranging survey of different kinds of psycholinguistic experiments aimed at uncovering such a distinction, Gibbs found that there is no evidence for a principled distinction between literal and figurative language.—Cognitive Linguistics: An Introduction, p. 287
