Right, No concept of numbers. They do not even have the number or concept of "one." Many experiments by MIT psychologist Ted Gibson, Stanford psychologist Mike Frank and others have shown this (experiments conducted in the field). As I have said, no Piraha parents knows how many children they have. But they all know the names of all their children and would never leave home without them.

Wari'. It is a Chapakuran language of Western Brazil, on the border with Bolivia. I have co-written a 547 page grammar of that language.

I have discussed this in my books and other writings and psychologists from Stanford, MIT, and Columbia have worked with me on these issues. It happens, to give the easy answer, because math, counting, etc have no utility for the people.

He believes that it is so obvious that all languages have recursion that one would have to be a liar to deny that (this is what he told me in a conversation). But also, yes, I think that he and many people believe that I have doctored the data. When one agrees with data, it makes sense. When one disagrees, one suspects...

Indeed. I did a monolingual demonstration for the Brazilian Indian Foundation, FUNAI, and the language they gave me was Wari' The Wari' speaker returned to the village and told a missionary, "This Daniel learned my language in 30 minutes." (False, haha). The missionary, Barbara Kern, asked me to write the grammar of the language with her. I did.
