“If Five Louis-d’ors may be of present Service to you, please draw on me for that Sum, and your Bill shall be paid on Sight. Some time or other you may have an Opportunity of assisting with an equal Sum a stranger who has equal need of it. Do so. By that means you will discharge any Obligation you may suppose yourself under to me. Enjoin him to do the same on Occasion. By pursuing such a Practice, much Good may be done with little money. Let kind Offices go round. Mankind are all of a Family.” — Benjamin Franklin, “Letter to William Nixon”, September 5, 1781
