Internet Encyclopedia of Philosophy. Universals. 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 it makes them controversial.
