Ten years on the moon could tell us more about the universe than a thousand years on the earth might be able to. - Isaac Asimov

"A couple of months ago I had a dream, which I remember with the utmost clarity. (I don't usually remember my dreams.)
I dreamed I had died and gone to Heaven. I looked about and knew where I was-green fields, fleecy clouds, perfumed air, and the distant, ravishing sound of the heavenly choir. And there was the recording angel smiling broadly at me in greeting.
I said, in wonder, "Is this Heaven?"
The recording angel said, "It is."
I said (and on waking and remembering, I was proud of my integrity), "But there must be a mistake. I don't belong here. I'm an atheist."
"No mistake," said the recording angel.
"But as an atheist how can I qualify?"
The recording angel said sternly, "We decide who qualifies. Not you."
"I see," I said. I looked about, pondered for a moment, then turned to the recording angel and asked, "Is there a typewriter here that I can use?"
The significance of the dream was clear to me. I felt Heaven to be the act of writing, and I have been in Heaven for over half a century and I have always known this."

You don't ask a computer if it is sure of the answer it disgorges;

I still can't quite grasp what you are telling me. I find it impossible to believe that there would be such unreasoning feeling against harmless people.
Amaryl said bitterly, "That's because you've never had any occasion to interest yourself in such things. It can all pass right under your nose and you wouldn't smell a thing because it doesn't affect you."
Dors said, "Mr. Amaryl, Dr. Seldon is a mathematician like you and his head can sometimes be in the clouds. You must understand that. I am a historian, however. I know that it isn't unusual to have one group of people look down upon another group. There are peculiar and almost ritualistic hatreds that have no rational justification and that can have their serious historical influence. It's too bad."
Saying something is 'too bad' is easy. You say you disapprove, which makes you a nice person, and then you can go about your own business and not be interested anymore. It's a lot worse than 'too bad.' It's against everything decent and natural. We're all of us the same, yellow-hairs and black-hairs, tall and short, Easterners, Westerners, Southerners, and Outworlders. We're all of us, you and I and even the Emperor, descended from the people of Earth, aren't we?
