"Each factory will be making Robots of a diťferent color, a different nationality, a different tongue; that they'll all be different — as different from one another as fingerprints; that they'll no longer be able to conspire with one another; and ... we, we people will help to foster their prejudices and cultivate their mutual lack of understanding, you see? So that any given Robot, to the day of its death, right to the grave, will forever hate a Robot bearing the trademark of another factory... Thunder, we'll make Black Robots and Swedish Robots and Italian Robots and Chinese Robots, and then let someone try to drive the notion of brotherhood into the noggin of their organization..."

“Dear Miss Glory, we've already had at least a hundred saviors and prophets here. Every boat brings another one. Missionaries, anarchists, the Salvation Army, everything imaginable. It would amaze you to know how many churches and lunatics there are in the world.”

“I don't say that it is a bad or useless profession: but it isn't one of the superlatively fine and striking ones, and the material used is of a strange sort — you don't even see it. But I'd like all the things I used to see to be in it: the ringing hammer-strokes of the smith and the colors of the whisping of the stone-mason, the bustling of the baker, the humility of the poor, and all the lusty strength and skill which men of towering stature put into their work before the astonished and fascinated eyes of a child.”

“Figh-ting in the Bal-kans." Lord Jesus, another of God's punishments! But that war'll get here too! Is it far from here?”

“Look, justice has to be as unquestioned as the multiplication tables. I don’t know if you could prove that every theft is wrong; but I can prove to you that every theft is against the law, because I can arrest you every time. If you scattered pearls in the street, then a policeman could give you a ticket for littering. But if you started performing miracles, we couldn’t stop you, unless we called it a public nuisance or unlawful public assembly. There must be some kind of breach of order for us to intervene.”

“O Adam, Adam! no longer will you have to earn your bread by the sweat of your brow; you will return to Paradise where you were nourished by the hand of God. You will be free and supreme; you will have no other task, no other work, no other cares than to perfect your own being. You will be the master of creation.”
