Discription: The author is widely known and deeply admired for being the founder of modern linguistics, one of the founders of the field of cognitive science, and perhaps the most avidly read political theorist and commentator of our time. In this book he present a lifetime of philosophical reflection on all three of these areas of research, to which he has contributed for over half a century. In clear, precise and non-technical language, he elaborates on fifty years of scientific development in the study of language, sketching how his own work has implications for the origins of language, the close relations that language bears to thought and its eventua biological basis. He expounds on and criticizes many alternative theories, such as those that emphasize the social, communicative and referential aspects of language. Chomsky reviews how new discoveries about language overcome what seemed to be highly problematic assumptions in the past. He also investigate the apparent scope and limts of human mind can seriously investigate, in light of the history of science and philosophical reflection and of current understanding. Moving from language and mind to society and political, Chomsky concludes with a searching exploration and philosophical defence of a position he describes as 'librtarian socialis', tracing its links to anarchism and the ideas of John Dewey and even the thought of Marx and Mill, and demonstrating its cnceptual growth out of our historical past and urgent relations to matters of the present.
