Noam Chomsky /

Avram Noam Chomsky ( /ˈnoʊm ˈtʃɒmski/; born December 7, 1928), known as Noam Chomsky, is an American linguist, philosopher, cognitive scientist, and activist. He is an Institute Professor and professor emeritus of linguistics at the Massachusetts Institute of Technology. Chomsky is well known in the academic and scientific community as one of the fathers of modern linguistics, and a major figure of analytic philosophy. Since the 1960s, he has become known more widely as a political dissident and an anarchist, referring to himself as a libertarian socialist. Chomsky is the author of more than 150 books and has received worldwide attention for his views. In the 1950s, Chomsky began developing his theory of generative grammar, which has undergone numerous revisions and has had a profound influence on linguistics. His approach to the study of language emphasizes "an innate set of linguistic principles shared by all humans" known as universal grammar, "the initial state of the language learner," and discovering an "account for linguistic variation via the most general possible mechanisms."
