Mandeville’s psychological examination of humankind, often perceived as cynical, is a large part of his genius and also his infamy. Much in keeping with the physician he was, it is fitting that he took on the task of diagnosing society in order to expose what he believed to be the true motives of humankind. Nonetheless, there was a religious component in Mandeville’s thought. His man was necessarily fallen man: capable only of pleasing himself, the individual human being was a postlapsarian creature, irredeemably selfish and greedy for its own private pleasure, at which it always aimed even if it hid such self-seeking behind more respectable facades ( The Fable , Vol. I, pg. 348). Mandeville’s examination showed the ways in which people hid their real thoughts and motives behind a mask in order to fake sociability by not offending the selfish pride of their peers. Ironically, Mandeville’s own honesty led him into trouble: he boldly claimed vice was inevitably the foundation of a thriving society, insofar as all human beings had to act viciously because their status as selfish fallen men ensured that whatever displays they affected, at bottom selfishness always dictated their actions. All social virtues are evolved from self-love, which is at the core irredeemably vicious. Mandeville also challenged conventional moral terminology by taking a term like “vice” and showing that, despite its negative connotations, it was beneficial to society at large.
