"It is an important and popular fact that things are not always what they seem.

For instance, on the planet Earth, man had always assumed that he was more intelligence 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 reason."
— Douglas Adams, English writer and humorist, born March 11, 1952
