In this book Noam Chomsky reflects on the history of 'generative enterprise' - his approach to the study of languages that revolutionized our understanding of human languages and other cognitive systems. In his lively and engaging style, he presents advances in current grammatical theory called 'Minimalist Program', sketches some of the key issues that have characterized generative grammar in recent years, and charts out the agenda for future research in language theory. Linguists interested in the internal history of generative linguistics will find this book insightful as also students and general readers who wish to gain an introductory knowledge of the discipline, its significance, and Chomsky's contribution.
