II. PLATO'S PROBLEM AND CHOMSKY'S SOLUTION
This imbalance between the external input--linguistic data-- and the output--complex linguistic knowledge-- is called Plato's problem. Chomsky's solution to the Plato's problem is to seek the richness in the processor--infant's brind--rather than in external stimuli.
Our knowledge of language is complex and abstract; the experience of language we receive is limited. Our minds could not create such complex knowledge on the basis of such sparse information.It must therefore come from somewhere other than the evidence we encounter; Plato's solution is from memories of prior existence, Chomsky's from innate properties of the mind. (Cook, 1988, p. 55)
Chomsky believes that child's brind is equipped with the principles and parameters of the Universal Grammar (UG) which underlies the grammar of any human language. With the help of this language-specific knowledge children can figure out roughly what the shape of his or her mother tongue is like. That is, UG provides a skeleta knowledge upon which the child is supposed to dress the flesh. To make an analogy, UG is similar to the genetic information in the seed of a flower and the external linguistic input is similar to the water which activates this latent information. It is vain to attribute the beauty of a flower only to the minerals in water, and the complexity of child's grammar to the external data only. Both water and input act as a trigger working on a rich genetic blueprint.
