“...either the gods are there whether you believe or not, or exist only as a function of the belief, so either way you might as well ignore the whole business...”

“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.”

“If you have not known love, then the only reason not to die is that life will get better or god exists. If you don't believe in either, perhaps it is time for you to go.”

“I knew then that I hadn't stopped believing in God. I'd just stopped believing God cared. There might be a God, Clary, and there might not, but I don't think it matters. Either way we're on our own.”

“Of course, the laws of science contain no matter and have no energy either and therefore do not exist except in people's minds. It's best to be completely scientific about the whole thing and refuse to believe in either ghosts or the laws of science. That way you're safe. That doesn't leave you very much to believe in, but that's scientific too.”

“Above all, you can believe in Providence in either of two ways, either as thirst believes in the orange, or as the ass believes in the whip.”
