François VI, Duc de La Rochefoucauld, Prince de Marcillac (French: 15 September 1613 – 17 March 1680) was a noted French author of maxims and memoirs. It is said[by whom?] that his world-view was clear-eyed and urbane, and that he neither condemned human conduct nor sentimentally celebrated it. Born in Paris on the Rue des Petits Champs, at a time when the royal court was vacillating between aiding the nobility and threatening it, he was considered an exemplar of the accomplished 17th-century nobleman. Until 1650, he bore the title of Prince de Marcillac.
