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 thomas aquinas c and even aristotle bc charlesworth the term occam's razor first appeared in in the works of sir william rowan hamilton long after ockham's death circa 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 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 thorburn i count 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
