It was a great thing to be a human being. It was something tremendous. Suddenly I'm conscious of a million sensations buzzing in me like bees in a hive. Gentlemen, it was a great thing.

You still stand watch, O human star, burning without a flicker, perfect flame, bright and resourceful spirit. Each of your rays a great idea - O torch which passes from hand to hand, from age to age, world without end.

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.

I certainly don't know if you could claim that every theft is wrong, but I'll prove to you that every theft is forbidden, by simply locking you up.

I find that a real gardener is not a man who cultivates flowers; he is a man who cultivates the soil. He is a creature who digs himself into the earth and leaves the sight of what is on it to us gaping good-for-nothings. He lives buried in the ground. He builds his monument in a heap of compost. If he came into the Garden of Eden, he would sniff excitedly and say: "Good Lord, what humus!"
