Chomsky places emphasis on the capacity of human languages to create new sentences in an infinite manner.

Chomsky boldly proclaims that this creativity is the "central fact to which any significant linguistic theory must address itself".

In doing so, this "far too oversimplified" linguistic model "seriously underestimates the richness of structure of language and the generative processes that underlie it".

[3] After dismissing the existing theories, Chomsky attempts to show that his newly invented "transformational generative grammar" model is "much closer to the truth".

A successful linguistic theory must achieve the higher level of "explanatory adequacy", describing the distinctive features of a natural language as opposed to any set of structural descriptions.
