‘This book … is very likely to become a classic, not only because of its potential implications for linguistics, cognitive psychology and anthropology, but because of the range and originality of the theory it proposes.’ – Pascal Engel, Revue Philosophique‘Cognitive science is very often marred by demarcation disputes and protectionist attitudes which have little or no rational basis. Occasionally, however, it works as it should and a book appears which reaches across the bread and butter lines which institutional life forces upon us. Relevance is, I think, such a book.’ – Alan Leslie, Mind and Language. ‘The repercussions of Relevance are likely in the long run to be great – felt first, perhaps, in the pragmatics of conversation, the philosophy of language, and reader-response criticism, but also in many other activities: construction of memory models, pedagogy, machine learning and (doubtless) advertising and propaganda.’ – Alastair Fowler, London Review of Books ‘I recommend this book to people interested in linguistics, philosophy of language and pragmatics, and, definitely, to people who cultivate an interest in semiotics.’ – Umberto Eco, L’Expresso ‘This is probably the best book you’ll ever read on communication.’ – Rhetoric Society Quarterly
