“A book has been taken. A book has been taken? You summoned the Watch," Carrot drew himself up proudly, "because someone's taken a book? You think that's worse than murder?"

“Dwarfs were not a naturally religious species, but in a world where pit props could crack without warning and pockets of fire damp could suddenly explode they'd seen the need for gods as the sort of supernatural equivalent of a hard hat. Besides, when you hit your thumb with an eight-pound hammer it's nice to be able to blaspheme. It takes a very special and strong-minded kind of atheist to jump up and down with their hand clasped under their other armpit and shout, "Oh, random-fluctuations-in-the-space-time-continuum!" or "Aaargh, primitive-and-outmoded-concept on a crutch!”

“Well, the traveling teachers do come through every few months," said the Baron.

"Yes, sir, I know, sir, and they're useless, sir. They teach facts, not understanding. It's like teaching people about forests by showing them a saw. I want a proper school, sir, to teach reading and writing, and most of all thinking, sir, so people can find what they're good at, because someone doing what they really like is always an asset to any country, and too often people never find out until it's too late.”

"But the gods plainly do exist," said a priest.

"It Is Not Evident."

A bolt of lightning lanced down through the clouds and hit Dorfl's helmet. There was a sheet of flame and then a trickling noise. Dorfl's molten armour formed puddles around his white-hot feet.

"I Don't Call That Much Of An Argument," said Dorfl calmly, from somewhere in the clouds of smoke.”
