“Most species do their own evolving, making it up as they go along, which is the way Nature intended. And this is all very natural and organic and in tune with mysterious cycles of the cosmos, which believes that there's nothing like millions of years of really frustrating trial and error to give a species moral fiber and, in some cases, backbone.”

“The Librarian considered matters for a while. So…a dwarf and a troll. He preferred both species to humans. For one thing, neither of them were great readers. The Librarian was, of course, very much in favor of reading in general, but readers in particular got on his nerves. There was something, well, sacrilegious about the way they kept taking books off the shelves and wearing out the words by reading them. He liked people who loved and respected books, and the best way to do that, in the Librarian’s opinion, was to leave them on the shelves where Nature intended them to be.”

“ASTONISHING, said Death. REALLY ASTONISHING. LET ME PUT FORWARD ANOTHER SUGGESTION: THAT YOU ARE NOTHING MORE THAN A LUCKY SPECIES OF APE THAT IS TRYING TO UNDERSTAND THE COMPLEXITIES OF CREATION VIA A LANGUAGE THAT EVOLVED IN ORDER TO TELL ONE ANOTHER WHERE THE RIPE FRUIT WAS.”

“Never trust a species that grins all the time. It’s up to something.”

“Your average witch is not, by nature, a social animal as far as other witches are concerned. There's a conflict of dominant personalities. There's a group of ringleaders without a ring. There's the basic unwritten rule of witchcraft, which is 'Don't do what you will, do what I say.' The natural size of a coven is one. Witches only get together when they can't avoid it.”

“Crowley had always known that he would be around when the world ended, because he was immortal and wouldn’t have any alternative. But he hoped it was a long way off. Because he rather liked people. It was major failing in a demon. Oh, he did his best to make their short lives miserable, because that was his job, but nothing he could think up was half as bad as the stuff they thought up themselves. They seemed to have a talent for it. It was built into the design, somehow. They were born into a world that was against them in a thousand little ways, and then devoted most of their energies to making it worse. Over the years Crowley had found it increasingly difficult to find anything demonic to do which showed up against the natural background of generalized nastiness. There had been times, over the past millennium, when he’d felt like sending a message back Below saying, Look we may as well give up right now, we might as well shut down Dis and Pandemonium and everywhere and move up here, there’s nothing we can do to them that they don’t do to themselves and they do things we’ve never even thought of, often involving electrodes. They’ve got what we lack. They’ve got imagination. And electricity, of course. One of them had written it, hadn’t he…”Hell is empty, and all the devils are here.”

“And that's when I first learned about evil. It is built in to the very nature of the universe. Every world spins in pain. If there is any kind of supreme being, I told myself, it is up to all of us to become his moral superior.”
