“Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?”

“Why should I want to make anything up? Life's bad enough as it is without wanting to invent any more of it.”

“The Saab seethed off into the night. Arthur watched it go, as stunned as a man might be who, having believed himself to be totally blind for five years, suddenly discovers that he had merely been wearing too large a hat.”

“It can be very dangerous to see things from somebody else's point of view without the proper training.”

“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.”

“Unfortunately this Electric Monk had developed a fault, and had started to believe all kinds of things, more or less at random. It was even beginning to believe things they'd have difficulty believing in Salt Lake City.”

“But that can't work, can it?" Said Richard. "If we do that, then this won't have happened. Don't we generate all sorts of paradoxes?"Reg stirred himself from thought. "No worse than many that exist already," he said. "If the universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don't. It's like a human body, you see. A few cuts and bruises here and there don't hurt it. Not even major surgery if its done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make. That isn't to say if you get involved in a paradox a few things won't strike you as being very odd, but if you've got through life without that already happening to you, then I don't know which universe you've been living in, but it isn't this one”
