Nothing is so contagious as example; never was there any considerable good or ill done that does not produce its like. We imitate good actions through emulation, and had ones through a malignity in our nature, which shame conceals, and example sets at liberty.
Francois de La RochefoucauldThose great and glorious actions that dazzle our eyes with their luster are represented by statesmen as the result of great wisdomand excellent design; whereas, in truth, they are commonly the effects of the humors and passions.
Francois de La Rochefoucauld
