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.

Now it is such a bizarrely improbable coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God.
The argument goes something like this: “I refuse to prove that I exist,’” says God, “for proof denies faith, and without faith I am nothing.”
“But,” says Man, “The Babel fish is a dead giveaway, isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. QED.”
“Oh dear,” says God, “I hadn’t thought of that,” and promptly vanishes in a puff of logic.
“Oh, that was easy,” says Man, and for an encore goes on to prove that black is white and gets himself killed on the next zebra crossing.

The Hitch Hiker’s Guide to the Galaxy has a few things to say on the subject of towels: a towel is about the most massively useful thing an interstellar hitch hiker can have. You can wrap it around you for warmth, you can lie on it, you can sleep under it beneath the stars, wet it for use in hand-to-hand-combat, you can wave your towel in emergencies as a distress signal and, of course, dry yourself off with it if it still seems to be clean enough.
