1. William Ockham (c. 1280–1349). English Scholastic Philosopher. The methodological principle known as Ockham’s Razor is usually formulated as “Entia non sunt multiplicanda praeter necessarium”. However, it is well known that neither this formulation of the principle nor the idea behind it come originally from William of Ockham. This particular formula is due to Leibniz, though Ockham’s works contain equivalent formulas. But Duns Scotus had also used the same principle before Ockham and he refers to it directly to Aristotle. For details see M.J. Charlesworth, Philosophical studies, 6 (1956) 105.
