Hello Martin:

You say this:
(My Question: Is it necessary to code the grammar rules?) I ask this question because the human brain cannot know which language it learns and so it also cannot know the (language)special grammar rules! (i hope you understand me)

I don't understand you, others do understand you. I know that our brains as soon as they have learned a part of our language they certainly know some grammar and know enough if what they hear belongs to their learned language. When you hear a Latin word order, you recognize that, isn't it. When I write I have the exercise made, that's very normal for Latin languages but not for English. Doesn’t your brain know that?

You mean of course when you look at mathematical rules nets, but our brain doesn't work in that way. They know nothing of rules. Ever seen spiking neurons. They act and look a result. It's just marvelous they can work so.
