Poncius and "Occam's razor"

The well-known formula “entia non sunt multiplicanda praeter necessitatem” (“One should only accept as many entities as absolutely necessary”), which for a long time was initially cited as the formulation of a nominalistic basic idea and then as a concise formulation of the concept of Occam's razor and often Wilhelm von Ockham was ascribed to, in fact has its oldest known document in Poncius, who in 1639 in Wadding's edition of Opus Oxoniense (by Duns Scotus) this sentence in the slightly different form "non sunt multiplicanda entia sine necessitate" than one in schools (" by scholastics ”) frequently quoted theorem. In the form that has become common since then, this theorem is first documented in the Logica Vetus et Nova (1654) by Johannes Clauberg .
