The 'Language Instinct' Debate examines the various arguments for instinctive knowledge, and finds that each one rests on false premisses or embodies logical fallacies. The structures of language are shown to be purely cultural creations.

With a new chapter entitled 'How People Really Speak' which uses corpus data to analyse how language is used in spontaneous English conversation, responses to critics, extensive revisions throughout, and a new preface by Paul Postal of New York University, this new edition will be an essential purchase for students, academics, and general readers interested in the debate about the 'language instinct'.
