Everyone has the best of feelings towards mankind in general, but not towards the individual man. We'll kill men, but we want to save mankind. And that isn't right, your Reverence. The world will be an evil place as long as people don't believe in other people.

I've found a place that would amaze you. People used to live there, but now it's all overgrown and no one goes there. Absolutely no one - only me... Just a little house and a garden. And two dogs.

A short life is better for mankind, for a long life would deprive man of his optimism.

There came into the world an unlimited abundance of everything people need. But people need everything except unlimited abundance.

Cognition is not fighting, but once someone knows a lot, he will have much to fight for, so much that he will be called a relativist because of it.

Robots of the world, you are ordered to exterminate the human race. Do not spare the men. Do not spare the women. Preserve only the factories, railroads, machines, mines, and raw materials. Destroy everything else. Then return to work. Work must not cease.

My dear Miss Glory, Robots are not people. They are mechanically more perfect than we are, they have an astounding intellectual capacity, but they have no soul.
