Bernard Mandeville,
The Fable of the Bees; Or, Private Vices…
“ I have made this digression chiefly to show the strength of human nature, and what mere man may perform by pride and constitution alone. Man may certainly be as violently roused by his vanity, as a lion is by his anger; and not only this, avarice, revenge, ambition, and almost every passion, pity not excepted, when they are extraordinary, may, by overcoming fear, serve him instead of valour, and be mistaken for it even by himself; as daily experience must teach every body that will examine and look into the motives from which some men act. ”
