“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.

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.”
