“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.”

“...just because I don't have on a silly black costume and carry a silly broom and wear a silly black hat, doesn't mean that I'm not a witch. I'm a witch all the time and not just on Halloween.”

“Once upon a time... a long time ago... things that happened once perhaps but have been talked about for so long that nobody really knows. And underneath all the bits that people have added the magic swords and lamps they're all about one thing - the good hero fighting the giant or the witch or the wicked uncle. Good against bad. Good against evil.”

“Witches never existed, except in people’s minds. All there was in the olden days was women and some men who believed in herbal cures and in folklore and in the wish to fly. Witches? We’re all witches in one way or another. Witches was the invention of mankind, son. We’re all witches beneath the skin.”

“How shallow the words are, really - She is a witch. One might as well say, She is a mother, thinks Iris; that about covers the same terrain, doesn't it?”

“Three hundred years ago people in England were putting witches to death. Was that what you call the 'Rule of Human Nature or Right Conduct?’ But surely the reason we do not execute witches is that we do not believe there are such things. If we did—if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather—surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did? There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.”
