This work examines Noam Chomsky's widely accepted ontological assumptions, now referred to as “biolinguistics”—and demonstrates that they are internally inconsistent. Notably, it is shown that Chomsky himself has at least once admitted this flaw.
Additionally, the volume challenges a fundamental assumption from Chomsky’s 1950s linguistic writings. This is the claim that the grammars of natural languages, particularly of English, must be constructive (proof-theoretic) devices, usually called generative grammars. It is shown that this persistent view cannot in principal account for a multitude of linguistic structures realized as perfectly natural sentences.
Finally, the work scrutinizes Chomsky’s frequent assertion that “there is essentially only one language spoken on Earth,” revealing it to have no actual substance.
The exposition of these flaws calls for a reassessment of fundamental aspects of generative linguistics.
