Mmm... language...

Related with the topic developed by Mark Pagel I can say that language is not just this, language is bigger than just talk and communicating.

If you use this topic in the anthropology, I could say the language can communicate a people context.  When you talk you are saying what you are thinking and why you think of this way.

The language can reproduce the behaviors of the people like Mr. Pagel says, you are teaching and learning at the same moment, as I said, language is more than just talk.

If you want to apply what I said to the Chilean society, we can observe that the different social class uses different kind of words to express oneself and the same thing reproduces the same behavior inside the same social class. For this reason you can differentiate the kind of people and at the same moment you can classify them, because you understand the each social class code.

Now, if we can understand the different social class codes we could take a thought and use it to complement what you know, concerning to the wise, and after you could give the tool which you built and give it to the society to change what something is wrong.
