The attached article by Howard Gardner (the seven intelligences) shines light on the linguistic philosophy of Noam Chomsky and others. In Chomsky language is presented as an innate human quality and although encoded in our DNA it unfolds as a mental organ, not entirely reducible to biological functioning of the brain, but exists as a mental reality in a somewhat Cartesian sense.

(Chomsky believes also that morality is innate in the human)

Language acquisition does not therefore require the structural interaction or developmental context ascribed by developmental psychologist - most notably Piaget -  which entails a learning process. Rather language unfolds as a pre-programmed capability of humans regardless of context.  Chomsky's student Jerry Fodor takes this proposition further and advances the notion of various modules of the human mind (or mental organs) which have specialized function, and as such dismisses the idea of the mind as a general central processing unit.

Chomsky has prevailed in his defenses of his model most notable in debates with B.F. Skinner (over turning behaviorism) and Piaget where he demonstrated that the developmentalist failed to treat language as a special case and moreover that language unfolds with or without the developmental interactions which Piaget saw as essential.

The shortcoming in Chomsky's work is perhaps a failure to fully appreciate the intervention of culture or its co-evolution with cultural symbol systems and the role they play in the acquisition and use of language and moreover perhaps he fails to appreciate that language co-evolves with the brain. Thus parts of the brain such as Broca Area and Wieneke Area which facilitate the language instinct and make physically possible the conditions for language to arise are because of their frequent usage strengthened and as such are better suited to be selected for further evolutionary adaptation.

At any rate this article from the New York Review does a great job in summing up current understanding and debates regarding the mental organ of language
