“This is very similar to the suggestion put forward by the Quirmian philosopher Ventre, who said, "Possibly the gods exist, and possibly they do not. So why not believe in them in any case? If it's all true you'll go to a lovely place when you die, and if it isn't then you've lost nothing, right?" When he died he woke up in a circle of gods holding nasty-looking sticks and one of them said, "We're going to show you what we think of Mr Clever Dick in these parts...”

“I wonder if it's like this for mountain climbers, he thought. You climb bigger and bigger mountains and you know that one day one of them is going to be just that bit too steep. But you go on doing it, because it’s so-o good when you breathe the air up there. And you know you'll die falling.”

“Om rubed his head. This wasn't god-like thinking. It seemed simpler when you were up here. It was all a game. You forgot that it wasn't a game down there. People died. Bits got chopped off. We're like eagles up here, he thought. Sometimes we show tortoise how to fly. Then we let go.”

“I don't hold with paddlin' with the occult," said Granny firmly. "Once you start paddlin' with the occult you start believing in spirits, and when you start believing in spirits you start believing in demons, and then before you know where you are you're believing in gods. And then you're in trouble.""But all them things exist," said Nanny Ogg."That's no call to go around believing in them. It only encourages 'em.”

“Anyway, lots of warrior tribes think that when they die, they go to a heavenly land somewhere," said the toad. "You know, where they can drink and fight and feast forever? So maybe this is theirs.""But this is a real place!""So? That's what they believe. Besides, they're only small. Maybe the universe is a bit crowded and they have to put heavens anywhere there's room? I'm a toad, so you'll appreciate that I'm having to guess a lot here.”

“He was trying to conjure up a succubus." It should be impossible to leer when all you've got is a beak, but the parrot managed it. "That's a female demon what comes in the night and makes mad passionate wossn-""I've heard of them," said Rincewind. "Bloody dangerous things."The parrot put its head on one side. "It never worked. All he ever got was a neuralger.""What's that?""It's a demon that comes and has a headache at you.”

“That's why it's always worth having a few philosophers around the place. One minute it's all is truth beauty and is beauty truth, and does a falling tree in the forest make a sound if there's no one there to hear it, and then just when you think they're going to start dribbling one of 'em says, incidentally, putting a thirty-foot parabolic reflector on a high place to shoot the rays of the sun at an enemy's ships would be a very interesting demonstration of optical principles.”
