here's the full quote:

Moralists don't really have beliefs. Sometimes they stumble on one, like on a child's toy left on the carpet. The toy must be put away immediately. And the child reprimanded. Centrism isn't change — not even incremental change. It is control. Over yourself and the world. Exercise it. Look up at the sky, at the dark shapes of Coalition airships hanging there. Ask yourself: is there something sinister in moralism? And then answer: no. God is in his heaven. Everything is normal on Earth.
