Are Universals Real?

Universals are a class of mind independent entities, usually contrasted with individuals (or so-called “particulars”), postulated to ground and explain relations of qualitative identity and resemblance among individuals. Individuals are said to be similar in virtue of sharing universals. An apple and a ruby are both red, for example, and their common redness results from sharing a universal. If they are both red at the same time, the universal, red, must be in two places at once. This makes universals quite different from individuals, and controversial. Whether universals are in fact required to explain relations of qualitative identity and resemblance among individuals has engaged metaphysicians for two thousand years. Disputants fall into one of three broad camps. Realists endorse universals. Conceptualists and Nominalists, on the other hand, refuse to accept universals and deny that they are needed. In the present article, the author explains various view concerning universals. Also, challenges faced by such approaches will be studied; and finally, based on a realist view, he will try to prove [existence of] universals.
