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 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.

Curiously enough, the dolphins had long known of the impending
destruction of the of the planet Earth and had made many attempts to
alert mankind to the danger; but most of their communications were
misinterpreted ...
