“It took place in the midnight in the University's Great Hall, in a welter of incense, candlesticks, runic inscriptions and magic circles, none of which was strictly necessary but which made the wizards feel better.”

“What is magic?There is the wizard's explanation... wizards talk about candles, circles, planets, stars, bananas, chants, runes and the importance of having at least four good meals every day.”

“Any fool could be a witch with a runic knife, but it took skill to be one with an apple corer.”

“Unseen University was much bigger on the inside. Thousands of years as the leading establishment of practical magic in a world where dimensions were largely a matter of chance in any case had left it bulging in places where it shouldn't have places. There were rooms containing rooms which, if you entered them, turned out to contain the room you'd started with, which can be a problem if you are in a conga line.”

“Wizards don't believe in gods in the same way that most people don't find it necessary to believe in, say, tables. They know they're there, they know they're there for a purpose, they'd probably agree that they have a place in a well-organised universe, but they wouldn't see the point of believing, of going around saying "O great table, without whom we are as naught." Anyway, either the gods are there whether you believe in them or not, or exist only as a function of the belief, so either way you might as well ignore the whole business and, as it were, eat off your knees.”

“The universe contains any amount of horrible ways to be woken up, such as the noise of the mob breaking down the front door, the scream of fire engines, or the realization that today is the Monday which on Friday night was a comfortably long way off. A dog's wet nose is not strictly speaking the worst of the bunch, but it has its own peculiar dreadfulness which connoisseurs of the ghastly and dog owners everywhere have come to know and dread. It's like having a small piece of defrosting liver pressed lovingly against you.”

“Any true wizard, faced with a sign like 'Do not open this door. Really. We mean it. We're not kidding. Opening this door will mean the end of the universe,' would automatically open the door in order to see what all the fuss is about. This made signs rather a waste of time, but at least it meant that when you handed what was left of the wizard to his grieving relatives you could say, as they grasped the jar, 'We told him not to.”
