Jealousy lives upon doubts. It becomes madness or ceases entirely as soon as we pass from doubt to certainty.
Francois de La RochefoucauldJealousy is in some measure just and reasonable, since it merely aims at keeping something that belongs to us or we think belongsto us, whereas envy is a frenzy that cannot bear anything that belongs to others.
Francois de La RochefoucauldThe reason why most women have so little sense of friendship is that this is but a cold and flat passion to those that have felt that of love.
