Chomsky believed there were innate ideas when it came to language. But cannot the patterns (deep structures) of language explained by the limitations of probable choice and the tendency towards linguistic efficiency, rather than some kind of pre-determined given?
In some ways this is what Chomsky is saying. But somehow there is a gap between his understanding of the physical reality and the reality of his language.
Language is a physical property and should be treated as such, not as some mystery akin to religions and gods.
