"What makes us so bitter against people..." - Quote by Francois De La Rochefoucauld

“It is with an old love as it is with old age a man lives to all the miseries, but is dead to all the pleasures.”

“One thing which makes us find so few people who appear reasonable and agreeable in conversation is, that there is scarcely any one who does not think more of what he is about to say than of answering precisely what is said to him.”

“If we had no faults, we would not derive so much pleasure from noting those of other people.”

“To be wronged is nothing unless you continue to remember it.”

“You have more of a feeling of personal resentment than I have. Perhaps, I have too little of it, but I never thought it paid.”

“Maybe it’s that I find it hard to forgive the follies and vices of others, or their offenses against me. My good opinion, once lost, is lost forever.”

“Don't think so much of your own Cunning, as to forget other Men's; a Cunning Man is overmatched by a cunning Man and a Half.”

“I believe that cunning is not only morally wrong but also politically expedient, and have therefore always discountenanced its use even from the practical standpoint.”

“The prince must be a lion, but he must also know how to play the fox.”
