“The duchess turned on Eugène with one of those insolent stares that envelop a man from head to foot, flatten him out, and leave him at zero.”

“Madame de Nucingen was already there, dressed with the deliberate aim of appealing to all eyes, knowing that thereby she would seem even more attractive to Eugène.”

“Young man,' Porbus said, seeing Poussin stare open-mouthed at a picture, 'Don't look at the canvas too long, it will drive you to despair.”

“In Paris, when certain people see you ready to set your foot in the stirrup, some pull your coat-tails, others loosen the buckle of the strap that you may fall and crack your skull; one wrenches off your horse's shoes, another steals your whip, and the least treacherous of them all is the man whom you see coming to fire his pistol at you point blank.”

“To that point, he had always found the vicomtesse overflowing with friendly politeness, that sweet-flowing grace conferred by an aristocratic education, and which is never truly there unless it comes, automatically and unthinkingly, straight from the heart.[...]For anyone who had learned the social code, and Rastignac had absorbed it all in a flash, these words, that gesture, that look, that inflection in her voice, summed up all there was to know about the nature and the ways of men and women of her class. He was vividly aware of the iron hand underneath the velvet glove; the personality, and especially the self-centeredness, under the polished manners; the plain hard wood, under all the varnish. [...] Eugène had been entirely too quick to take this woman's word for her own kindness. Like all those who cannot help themselves, he had signed on the dotted line, accepting the delightful contract binding both benefactor and recipient, the very first clause of which makes clear that, as between noble souls, perfect equality must be forever maintained. Beneficience, which ties people together, is a heavenly passion, but a thoroughly misunderstood one, and quite as scarce as true love. Both stem from the lavish nature of great souls.”

“There is something noble as well as terrible about suicide. The downfall of many men is not dangerous, for they fall like children, too near the ground to do themselves harm. But when a great man breaks, he has soared up to the heavens, espied some inaccessible paradise, and then fallen from a great height. The forces that make him seek peace from the barrel of a gun cannot be placated. How many young talents confined to an attic room wither and perish for lack of a friend, a consoling wife, alone in the midst of a million fellow humans, while throngs of people weary of gold are bored with their possessions.”

“What moralists describe as the mysteries of the human heart are solely the deceiving thoughts, the spontaneous impulses of self-regard. The sudden changes in character, about which so much has been said, are instinctive calculations for the furtherance of our own pleasures. Seeing himself now in his fine clothes, his new gloves and shoes, Eugène de Rastignac forgot his noble resolve. Youth, when it swerves toward wrong, dares not look in the mirror of conscience; maturity has already seen itself there. That is the whole difference between the two phases of life.”
