“Granny Weatherwax was a witch. That was quite acceptable in the Ramtops, and no one had a bad word to say about witches. At least, not if he wanted to wake up in the morning the same shape as he went to bed.”

“And Granny Weatherwax was pretty damn powerful. She was probably an even more accomplished witch than the infamous Black Aliss and everyone knew what happened to her at the finish.”

“Mrs. Earwig (pronounced Ar-wige, at least by Mrs. Earwig) believed in shiny wands, and magical amulets and mystic runes and the power of the stars, while Granny Weatherwax in cups of tea, dry biscuits, washing every morning in cold water and, well...mostly she believed in Granny Weatherwax.”

“You needed at least three witches for a coven. Two witches was just an argument.”

“Granny was an old-fashioned witch. She didn’t do good for people, she did right by them.”

“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.”

“What is magic?Then there is the witches' explanation, which comes in two forms, depending on the age of the witch. Older witches hardly put words to it at all, but may suspect in their hearts that the universe really doesn't know what the hell is going on and consists of a zillion trillion billion possibilities, and could become any one of them if a trained mind rigid with quantum certainty was inserted into the crack and twisted; that, if you really had to make someone's hat explode, all you needed to do was twist into that universe where a large number of hat molecules all decide at the same time to bounce off in different directions.Younger witches, on the other hand, talk about it all the time and believe it involves crystals, mystic forces, and dancing about without yer drawers on. Everyone may be right, all at the same time. That's the thing about quantum.”
