The essence of language: An historical analysis of Chomsky's theory of language

In a review of Chomsky's writings from 1957 to 1980 concerning the universal and essential form of language (universal grammar and deep structures), Chomsky's theory of language can be shown to have evolved through three major periods; the grammatical (1957-1964), the Aristotelian (1965-1967), and the Kantian (1972 on). The most influential and known version of Chomsky's theory of language is that of his Aristotelian period (mainly Aspects of Syntax, 1965) in which Chomsky maintains that the essential form of sentences is strictly categorical.;Chomsky's analysis of all sentences as categorical in essence is incompatible with the Russellian logic. Russell's logic allows for relations which are not reducible to a subject-predicate form.
