Nothing 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 RochefoucauldThe secret of pleasing in conversation is not to explain too much everything; to say them half and leave a little for divination is a mark of the good opinion we have of others, and nothing flatters their self-love more.
Francois de La Rochefoucauld
