It is argued that Cartesian linguistics failed to claim a place for Chomsky among the classics of philosophy because the book was "widely and rightly judged to be a radical failure". The criticism is summarized be explaining that Chomsky had interpreted philosophical sources and used their terminology in a misleading way. Historians and philosophers argued that Chomsky's nativist theory of language does not represent rationalism because he is merely referring to its concept of innate ideas. However, lacking such a concept itself, Chomsky's version of Universal grammar does not have a place in rationalism.
