The book presents an integrated model of vagueness as an implicit and persuasive strategy, pervasive in everyday language use and public discourse. It considers three macro-dimensions of the phenomenon: linguistic-theoretical, psychological, and social-discursive.
It shows how vagueness can be strategically employed to elude recipients’ critical evaluation of intended contents, to deresponsibilize the source and make their arguments unchallengeable.
It explores the semiotic, semantic, pragmatic and psycholinguistic nature of vagueness, and looks at its use in contemporary public (with a focus on Italian) discourse.
It also delves into under-explored aspects of the phenomenon such as: the continuum of intentionality in the use of vague expressions; the evolutionary significance of vagueness; its implicitating and persuasive functions; the phenomenon of vagueness by implicature; the interaction between vague expressions and context precisation; the cognitive functioning of vague expressions; the use of vagueness in contemporary persuasive vs. non-persuasive text types; gender-based differences in the use of vagueness in public discourse.
