Francois de La Rochefoucauld
  • In most of mankind gratitude is merely a secret hope of further favors.

  • One is never fortunate or as unfortunate as one imagines.

  • Jealousy contains more of self-love than of love.

  • Jealousy is bred in doubts. When those doubts change into certainties, then the passion either ceases or turns absolute madness.

  • Jealousy lives upon doubts. It becomes madness or ceases entirely as soon as we pass from doubt to certainty.
