Why is it, I wonder, that anyone who displays superior athletic ability is an object of admiration to his classmates, while one who displays superior mental ability is an object of hatred?

As artists and traders in medieval cities began to form organizations, they instituted tough initiation ceremonies. Journeymen in Bergen, Norway, were shoved down a chimney, thrown three times into the sea, and soundly whipped. Such rites made belonging to the guild or corporation more precious to those who were accepted, and survived.

The whole world might know you and acclaim you, but someone in the past, forever unreachable, forever unknowing, spoils it all.

Properly read, the Bible is the most potent force for atheism ever conceived.

Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes. I personally resent it bitterly.
