:: If I understand you correctly (not at all sure I do) you are making an appeal to Authority.
You asked for examples of "data that we are born with". I thought that you meant any examples of such data, and - being a naturally helpful person - I gave you the example from the field of human language acquisition. I paid some lip service to Chomsky - that's true, but I'm not sure at what point it became "an appeal to authority".
Then you came up with your exclammation:
:: Innate language and Noam Chomsky?
:: He, (Chomsky) is not saying that language itself is born into us (babies don't speak French or Polish from birth) but the sense of grammar is born into us. That is, the ability to create useful rules to organize expression.
The answer to your surprisal and the contradiction that followed is this again:
Chomsky didn't just mean "the ability to create useful rules to organize expressions". I don't think Chomsky would have ever become known if this had been his main point, Terry :)
Mystical as it may sound, what Chomsky in fact claimed was that there is a set of ready-made rules on which all natural languages are based, and that all children must have access to those rules in order to develop language-specific communication skils. THese rules can be represented as logical expressions of the form: A --> B + C
In other words, French, Chinese and English have all a common denominator in the form of an abstract Universal Grammar. With time Chomsky even began to claim that there is a "language acquisition device" - a neurological entity (ie: piece of brain) which encompasses this inborn knowledge.
This is not an appeal to authority. I'm just commenting on what you said Chomsky's view on language acquisition was.
Now what is the evidence that you asked about? Agan my disclaimer comes here: I'm not totally convinced by this evidence - but I find it hard to ignore altogether.
1) Language universals
2) The poverty of stimulus argument
3) Language acquisition studies (the critical age hypothesis)
There's no point in trying to elaborate on all of that now, I'm just giving you some pointers:
1) Let's skip it for now.
2) The poverty of stimulus argument means that there are "principles of grammar that cannot be learned on the basis of positive input alone, however complete and grammatical that evidence is".
In other words, there's not much evidence to the effect that all language can really be acquired in this paradigm:
stimulus - response - feedback -
stimulus - better_response - more feedback -
stimulus - even better response - even more feedback etc...
unless you assume that some set of of universal rules are "encoded" in our brains prenatally.
3) Acquiring language is different from learning it. The fact that language can only be "fully" acquired before the critical age of 12-14 is sometimes explained with the claim that it is the only time in your neurological development when "the language acquisition device" gets activated. After this period you can only learn the language by understading the rules of grammar and consciously learning from your mistakes and so forth.
---------------
So what? So although Chomsky is not my greatest linguistic authority, I find some of his observations abuot language acquisition irrefutable. It's reasoning by negation, but it makes me think twice before I say that there are no examples of innate knowledge. In other words:
I do believe that some aspectc of linguistic knowledge are inborn!!!!
Hope it does it for you, Terry. If I'm still not clear enough, forget it, as it is probably due to the fact that my language acquisition device was only exposed to Polish and not English when before I reached the critical period.
