If you are to judge a man, you must know his secret thoughts, sorrows, and feelings; to know merely the outward events of a man's life would only serve to make a chronological table-a fool's notion of history.
When tempted to be unfaithful, the intellectual woman will try to inspire her husband with indifference, the sentimental woman with hatred, and the passionate woman with disgust.
Most geometricians, chemists, mathematicians, and great scientists submit religion to reason only to discover a problem as unsolvable as that of squaring a circle.
Women are tenacious, and all of them should be tenacious of respect; without esteem they cannot exist; esteem is the first demand that they make of love.
Though your vulgarian does not readily admit that feelings can change overnight, certainly two lovers often part far more abruptly than they came together.
A woman questions the man who loves exactly as a judge questions a criminal. This being so, a flash of the eye, a mere word, an inflection of the voice or a moment's hesitation suffice to expose the fact, betrayal or crime he is attempting to conceal.
Everything becomes agitated. Ideas quick-march into motion like battalions of a grand army to its legendary fighting ground, and the battle rages. Memories charge in, bright flags on high; the cavalry of metaphor deploys with a magnificent gallop; the artillery of logic rushes up with clattering wagons and cartridges; on imagination's orders, sharpshooters sight and fire; forms and shapes and characters rear up; the paper is spread with ink - for the nightly labor begins and ends with torrents of this black water, as a battle opens and concludes with black powder.
Constancy will always be the genius of love, the indication of that strength which constitutes the poet. A man should possess all women in his wife, like those squalid poetasters of the seventeenth century who made fair Irises and dazzling Chloes of their lowly Manons.
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.
