“If you have any mind to keep my respect, I recommend you not to add imbecility to these qualities by imagining that such a girl as I am will be content with your asthmatic love, and not look for youth and good looks and pleasure by way of a variety—”

“How did you get back?' asked Vautrin. 'I walked,' replied Eugene.'I wouldn't like half-pleasures, myself,' observed the tempter. 'I'd want to go there in my own carriage, have my own box, and come back in comfort. All or nothing, that's my motto.''And a very good one,' said Madame Vauquer.”

“Yes,' Montriveau went on in an unsteady voice, 'this Catholic faith to which you wish to convert me is a lie that men make for themselves; hope is a lie at the expense of the future; pride, a lie between us and our fellows; and pity, and prudence, and terror are cunning lies. And now my happiness is to be one more lying delusion; I am expected to delude myself, to be willing to give gold coin for silver to the end. If you can so easily dispense with my visits; if you confess me neither as your friend nor your love, you do not care for me! And I, poor fool that I am, tell myself this, and know it, and love you!”

You'll find I have some tremendous abysses, some huge, focused emotions that fools think of as vices, but you'll never find me lazy, and you'll never find me ungrateful. In a word, I'm neither a pawn nor a bishop, my young friend, but a castle.”

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.”

“Ah! What pleasure it must be to a woman to suffer for the one she loves!”
