《语言与心智(第3版)》主要内容：This is the long-awaited third edition of Chomsky' s outstanding collection of essays on Language and mind. The first six chapters, originally published in the 1960s, made a groundbreaking contribution to linguistic theory. This new edition complements them with an additional chapter and a new preface, bringing Chomsky' s influential approach into the twenty-first century. Chapters 1-6 present Chomsky's early work on the nature and acquisition of language as a genetically-endowed, biological system （Universal Grammar）, the rules and principles of which we acquire as internalized knowledge （I-language）. Over the past fifty years, this framework has sparked an explosion of inquiry into a wide range of languages, and has yielded some major theoretical questions. The final chapter revisits the key issues, reviewing the "biolinguistic" approach that has guided Chomsky' s work from its origins to the present day, and raising some novel and exciting challenges for the study of language and mind.
