This was like watching murder. Defilement. And it was something worse than either of those things. Even among his family, black trade as they were, books were holy things.

Mark nodded even though she couldn't see. He'd suddenly lost any desire to talk, and his plans for a perfect day washed away with the stream. The memories. They never let him go, not even for a half hour. They always had to rush back in, bringing all the horror.

Everything at some point has been declared the root of all evil.

Evil then consists not in being created but in the rebellious idolatry by which humans worship and honour elements of the natural world rather than the God who made them. The result is that the cosmos is out of joint.

The world is evil only when you become its slave.
