Editing Universal (metaphysics) (section)

==Nominalism==
Nominalists hold that universals are not real mind-independent entities but either merely concepts (sometimes called "conceptualism") or merely names. Nominalists typically argue that properties are abstract particulars (like tropes) rather than universals. [[JP Moreland]] distinguishes between "extreme" and "moderate" nominalism.<ref>Moreland (2001).</ref> Examples of nominalists include Buddhist logicians and [[apoha]] theorists,<ref>{{Cite book |last=Perrett |first=Roy W. |url=https://www.cambridge.org/highereducation/books/an-introduction-to-indian-philosophy/B9CD240194015F1D13BCDE7CA376CB86#contents |title=An Introduction to Indian Philosophy |date=2016-01-25 |publisher=Cambridge University Press |isbn=978-0-521-85356-9 |edition=1 |pages=133 |doi=10.1017/cbo9781139033589}}</ref> the medieval philosophers [[Roscelin of Compiègne]] and [[William of Ockham]] and contemporary philosophers [[W.
