":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:www.wikipedia.org +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,
