Hah, that sounds almost like something out of a book.

"For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much—the wheel, New York, wars and so on—whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man—for precisely the same reasons." - Douglas Adams, H2G2

Although I do think that without a way to store knowledge outside the brain it becomes much harder to form and maintain societies. Ian Stewart uses a wonderful term for that part of intelligence which we cannot hold inside our heads: extelligence. An external store of knowledge and (mis)information allows for sources of reference even when no other people with the knowledge happen to be available.
