Chomsky is an evolutionary figure in linguistics. His greatest contribution lies in transformational generative grammar, which put an end to the leading position structuralism had held in language for more than 30 years. His naturalistic methodology has greatly influenced the research of both linguistics and psychology, and he is also considered to be the first to study language from the cognitive perspective. He insists on a naturalistic methodology; therefore, he was even considered by some to be a physicalist. However, this is not the case. On the contrary, TGG, as a critique of the behaviorist view of language, is intertwined with a critique of physicalism. On the one hand, he thinks the mind, like chemical elements and electrons, can be approached from a third-person perspective; on the other hand, he again admits there exists consciousness, which can be merely approached in terms of a first-person authority, which, therefore, is a fatal challenge to his core theory. Now there remains a new solution to this dilemma, that is, to admit that the mind is a special natural phenomenon with two means of existence: one is involved in physical aspects with the brain, and the other is concerned with something mental, with the former approached by a third-person perspective and the latter better researched via a first-person authority.
