apeiron said:Complexity of a higher order (like life and mind) can arise if a system discovers the trick of constructing its own constraints.What matters in the mind is that an idea, an anticipatory image, forms. This is going to happen every moment anyway because that is how brains are structured. But states of mind can be constructed via acts of verbally-base, recursively nested, constraint.
Isn't "constructing it's own constraints" just the nativist position?
apeiron said:Sure, you can get obsessed about the hunt for a brain module which does "syntactic constraint". Stick a person's head in a scanner, ask them to generate regular and irregular verbs, and you will find different parts of the brain working hard. Perhaps the left dorsolateral prefrontal for regular verbs, and the left superior frontal gyrus for the irregular (until the next study using german rather than english speakers contradicts you).
But this is missing the point. Brains are already hierarchically organised. And the cause that is making such a "neuroscientific" difference in humans is not the addition of some novel brain module/genetic modification but another level of the epistemic cut. That is what needs to be the focus of attention.
Maybe I'm mistaken but I don't think they are suggesting a "brain module". I think the argument is for "mental" module. It's not clear if such modules can be accommodated within neural mechanisms as presently understood. I think that's why Chomsky writes:
The familiar slogan about the mental and the neurophysiological has the matter backwards: it should not be taken as a characterization of the mental, but rather as a hypothesis about neurophysiology: perhaps the neurophysiological is the mental at a “lower” level, perhaps not. As of now, we have more reason to feel secure about the mental than about the neurophysiological.
Pythagorean said:The point, I thought, was whether the "environment" influenced the evolution of the "particle"; and even in the case of hydrogen fusing into helium, it was only under the conditions produced by the stars that the hydrogen atoms overcame their electroweak interactions and found the more favorable strong interaction. It was a synthesis of both external and internal forces.
Nobody is claimimg that the environment plays no role just a secondary, minor role. With respect to language, the environment just can't deliver the goods or so goes the argument for reasons as the following:
An important argument in favor of the generative approach is the Poverty of the stimulus argument. The child's input (a finite number of sentences encountered by the child, together with information about the context in which they were uttered) is in principle compatible with an infinite number of conceivable grammars. Moreover, few if any children can rely on corrective feedback from adults when they make a grammatical error. Yet, barring situations of medical abnormality or extreme privation, all the children in a given speech-community converge on very much the same grammar by the age of about five years. An especially dramatic example is provided by children who for medical reasons are unable to produce speech, and therefore can literally never be corrected for a grammatical error, yet nonetheless converge on the same grammar as their typically developing peers, according to comprehension-based tests of grammar. Considerations such as these have led Chomsky, Jerry Fodor, Eric Lenneberg and others to argue that the types of grammar that the child needs to consider must be narrowly constrained by human biology (the nativist position).These innate constraints are sometimes referred to as universal grammar, the human "language faculty," or the "language instinct"
