 Not all Essentialists agree that linguistics studies aspects of what is in the mind or aspects of what is human. There are some who do not see language as either mental or human, and certainly do not regard linguists as working on a problem within cognitive psychology or neurophysiology. The debate on the ontology of language has seen three major options emerging in the literature. Besides the mentalism of Chomskyan linguistics, Katz (1981), Katz and Postal (1991) and Postal (2003) proffered a platonistic alternative and finally nominalism was proposed by Devitt (2006).
