Daniel Everett described in his book 
[Dont sleep there are snakes][1] the language of an Amazonian tribe (Piraha) which has no words for numbers. This tribe also uses "immediacy of experience" for believing other people. The author also argues that this language is a counter-example to the idea of a language instinct as proposed by Whorf and Chomsky.

Caleb Everett in [Numbers and the Making of Us: Counting and the Course of Human Cultures][2] argues, based on the language of the Piraha, that counting is a cultural achievement and not laid down in the structure of the brain. 

A review of Caleb Everett's book is in the [New York Times][3].
