Belief sloshes around in the firmament like lumps of clay spiralling into a potter's wheel. That's how gods get created, for example. They clearly must be created by their own believers, because a brief resume of the lives of most gods suggests that their origins certainly couldn't be divine. They tend to do exactly the things people would do if only they could, especially when it comes to nymphs, golden showers, and the smiting of your enemies.
Terry PratchettIn the words of the philosopher Sceptum, the founder of my profession: am I going to get paid for this?
Terry PratchettThe theater troubled her. It had a magic of its own, one that didn’t belong to her, one that wasn’t in her control. It changed the world, and said things were otherwise than they were. And it was worse than that. It was magic that didn’t belong to magical people. It was commanded by ordinary people, who didn’t know the rules. They altered the world because it sounded better.
