“Someone has to do it. It's all very well calling for eye of newt, but do you mean Common, Spotted or Great Crested? Which eye, anyway? Will tapioca do just as well? If we substitute egg white will the spell a) work b) fail or c) melt the bottom out of the cauldron? Goodie Whemper's curiosity about such things was huge and insatiable*. * Nearly insatiable. It was probably satiated in her last flight to test whether a broomstick could survive having its bristles pulled out one by one in mid-air. According to the small black raven she had trained as a flight recorder, the answer was almost certainly no.”

“Balance. It was all about balance. That had been one of the first things that she had learned: the centre of the seesaw has neither up nor down, but upness and downness flow through it while it remains unmoved. You had to be the centre of the seesaw so the pain flowed through you, not into you. It was very hard. But she could do it!”

“She sat silently in her rocking chair. Some people are good at talking, but Granny Weatherwax was good at silence. She could sit so quiet and still that she faded. You forgot she was there. The room became empty.Tiffany thought of it as the I’m-not-here spell, if it was a spell. She reasoned that everyone had something inside them that told the world theywere there. That was why you could often sense when someone was behind you, even if they were making no sound at all. You were receiving their I-am-here signal.Some people had a very strong one. They were the people who got served first in shops. Granny Weatherwax had an I-am-here signal that bounced off the mountains when she wanted it to; when she walked into a forest, all the wolves and bears ran out the other side. She could turn it off, too. She was doing that now. Tiffany was having to concentrate to see her. Most of her mind was telling her that there was no one there at all.”

“There was a wicked ole witch once called Black Aliss. She was an unholy terror. There's never been one worse or more powerful. Until now. Because I could spit in her eye and steal her teeth, see. Because she didn't know Right from Wrong, so she got all twisted up, and that was the end of her."The trouble is, you see, that if you do know Right from Wrong, you can't choose Wrong. You just can't do it and live. So.. if I was a bad witch I could make Mister Salzella's muscles turn against his bones and break them where he stood... if I was bad. I could do things inside his head, change the shape he thinks he is, and he'd be down on what had been his knees and begging to be turned into a frog... if I was bad. I could leave him with a mind like a scrambled egg, listening to colors and hearing smells...if I was bad. Oh yes." There was another sigh, deeper and more heartfelt."But I can't do none of that stuff. That wouldn't be Right."She gave a deprecating little chuckle. And if Nanny Ogg had been listening, she would have resolved as follows: that no maddened cackle from Black Aliss of infamous memory, no evil little giggle from some crazed Vampyre whose morals were worse than his spelling, no side-splitting guffaw from the most inventive torturer, was quite so unnerving as a happy little chuckle from a Granny Weatherwax about to do what's best.”

“People flock in, nevertheless, in search of answers to those questions only librarians are considered to be able to answer, such as "Is this the laundry?" "How do you spell surreptitious?" and, on a regular basis, "Do you have a book I remember reading once? It had a red cover and it turned out they were twins.”

“The only thing known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Wheedle. He reasoned like this: you can't have more than one king, and tradition demands that there is no gap between kings, so when a king dies the succession must therefore pass to the heir instantaneously. Presumably, he said, there must be some elementary particles -- kingons, or possibly queons -- that do this job, but of course succession sometimes fails if, in mid-flight, they strike an anti-particle, or republicon. His ambitious plans to use his discovery to send messages, involving the careful torturing of a small king in order to modulate the signal, were never fully expanded because, at that point, the bar closed.”

“Things just happen, one after another. They don't care who knows. But history... ah, history is different. History has to be observed. Otherwise it's not history. It's just... well, things happening one after another.”
