One, Two, Many - Language Shapes Thought

Chuck1318 writes "The Piraha tribe in the Amazon has only three words used in counting, that mean one, two, and many. A psychologist testing them has found that they are unable to accurately perform tasks involving quantities as few as four or five. He says that this shows that, at least for numbers, language shapes and limits how people can think." I can't help but be reminded of the gully dwarves from Dragonlance when reading this.
