This is the highly anticipated third edition of Chomsky's excellent collection of essays on language and mind.

The first six chapters, originally published in the 1960s, made groundbreaking contributions to linguistic theory.

This new edition complements them with an additional chapter and a new preface, bringing Chomsky's significant 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), through the rules and principles by which we internalize knowledge (E-language). Over the past fifty years, this theoretical framework has led to an explosion of research on a wide range of languages and has raised some major theoretical questions.

The final chapter reexamines crucial issues, providing an overview of the "biolinguistic" approach that has guided Chomsky's work from its inception to the present day, and posing some new and exciting challenges for the study of language and mind.

"A particularly welcome updated edition of one of Chomsky's classics. The new preface and final chapter provide an accessible and insightful approach to the background, direction, and evolution of Chomsky's efforts to 'biologize' language."

(James McGilvray, editor of The Cambridge Companion to Chomsky)
