The heart of man ever finds a constant succession of passions, so that the destroying and pulling down of one proves generally tobe nothing else but the production and the setting up of another.
Francois de La RochefoucauldNothing is more contagious than example, and no man does any exceeding good or exceeding ill but it spawns new deeds of the same kind. The good we imitate through emulation, the ill through the malignity of our nature, which shame keeps locked up, but example sets free.
Francois de La Rochefoucauld
