"Occam's Razor" is an often used term in American discussions. Relating to the philosophical principle non sunt multiplicanda entia praeter necessitatem it is used colloquially to state that things should not be complicated more than necessary. Actually, William Occam(1290-1349), an English friar exiled in Munich for many years, did not invent Occam's Razor. He just used the non sunt multiplicanda entia praeter necessitatem principle in the famous philosophical discussion between the Nominalists and the Universalists. The intellectual razor had been invented twenty years earlier by another monk, the French philosopher Durand de Saint-Pourçain (1270-1334). I think it is symptomatic that the term hasn't become popular with our intellectuals. Multiplicanda entia praeter necessitatem always was, and still, is their favorite game.
