All the hundreds of millions of people who, in their time, believed the Earth was flat never succeeded in unrounding it by an inch.

Creationists make it sound as though a 'theory' is something you dreamt up after being drunk all night.

It was childish to feel disappointed, but childishness comes almost as naturally to a man as to a child.

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.

The appearance of strength is all about you. It would seem to last forever.

The storm-blast whistles through the branches of the Empire even now. Listen... and you will hear the creaking.
