If you want creative and successful children, resign yourself to jousting with rebels.

Don't assume that a species is intelligent because it produces intelligent individuals.

The cultures we can look at had already grasped the essential unity of nature. No board of gods can survive that knowledge.

People who wear their religion on their sleeves talk a lot about going to Sunday school, reading the Bible, and doing good works. And I suppose there's no harm in that. But if I'd gone to the trouble to pull all this together ... and people never paid any attention to it, never bothered to try to find out how the world worked, then I think I'd get annoyed.

An optimist is somebody who thinks our various political and social systems, schools and churches, support groups and Boy Scout troops, jury trials and congressional committees, are on the up-and-up.
