There are many philosophical positions in relation to the universal. As an example of “beauty,” there are four positions: most do not consider classes to be universal, although some renowned philosophers do, such as John Bigelow. Nominalists believe that universalities are not true entities independent of the mind, but only concepts (sometimes called “conceptualism”), namely only names. Nominalists generally argue that properties are abstract (such as the tropics) and not universal. JP Moreland distinguishes between “extreme” and “moderate” nominalism.  The medieval philosophers Roscelin de Compiégne and Guillaume d`Ockham and contemporary philosophers W. V. Quine, Wilfred Sellars, D.C. Williams and Keith Campbell are examples of nominalists. Contemporary realists agree with the thesis that universals are multiplied entities. Examples are D.M. Armstrong, Nicholas Wolterstorff, Reinhardt Grossmann, Michael Loux. In metaphysics, the universal is what certain things have in common, that is, characteristics or qualities.
In other words, universal entities are reproducible or recurrent entities that can be inseucized or illustrated by many specific things.  Suppose there are two chairs in a room, each of which is green. These two chairs share both the quality of the “serenity” as well as the green or the quality of the greenery; In other words, they share a “universal.” There are three main types of properties or properties: species or species (e.g.B. mammals), properties (z.B. short, strong) and relationships (for example. B father`s, next door). These are all different types of universals.  Platonic realism refers to universality as a reference to general expressions, such as abstract, non-physical, non-spiritual beings, to which refer words such as “parable,” “circulationality” and “beauty.” In particular, there are references to proper names, such as “Phaedo,” or descriptions that identify individual objects, such as the phrase, “read there.” Other metaphysical theories may use the terminology of universal entities to describe physical entities. The principle of Ness ity-hood is mainly used by English-speaking philosophers to generate comfortable and concise names for universal properties or properties.  According to the Ness Ity Hood principle, a name can be created for each universal name by taking the name of the predicate and adding the suffix “ness,” “ity” or “hood.” For example, the universal, characteristic of left-handers, can be formed by taking the “left-handed” predicate and adding “ness,” which gives the name “left-hander.” The principle is most useful in cases where there is no established name or standard of the universal in ordinary English usage: what is the universal distinction of smarker chairs called? “Chair” in English is used not only as a theme (as in “The Chair Is Broken”), but also as a predicate (as in “It`s a Chair”).
