Thanks again JA In the Ockham s razor article we have The origins of what has come to be known as Occam s razor are traceable to the works of earlier philosophers such as John Duns Scotus 1265 1308 Thomas Aquinas c 1225 1274 and even Aristotle 384 322 BC Charlesworth 1956 The term Occam s razor first appeared in 1852 in the works of Sir William Rowan Hamilton 1805 1865 long after Ockham s death circa 1349 Ockham did not invent the razor so its association with him may be due to the frequency and effectiveness with which he used it Ariew 1976 And though he stated the principle in various ways the most popular version was written not by himself but by John Ponce of Cork in 1639 Thorburn 1918 I count 3 three external references and no unfortunately Also a google search site unfortunately returns only Aristotle with a similar phrasing referring to an non extant treatise At the minimum I would prefer the removal of unfortunately or a weaker rephrasing along the lines of unfortunately for historians of science with an internal wikilink to Ockham s razor History Thanks
