In Aristotle 's view, universals are incorporeal and universal, but only exist only where they are instantiated; they exist only in things. Aristotle said that a universal is identical in each of its instances. All red things are similar in that there is the same universal, redness, in each thing. There is no Platonic Form of redness, standing apart from all red things; instead, each red thing has a copy of the same property, redness. For the Aristotelian, knowledge of the universals is not obtained from a supernatural source. It is obtained from experience by means of active intellect.

Plato believed that there was a sharp distinction between the world of perceivable objects and the world of universals or forms: one can only have mere opinions about the former, but one can have knowledge about the latter. For Plato it was not possible to have knowledge of anything that could change or was particular, since knowledge had to be forever unfailing and general. For that reason, the world of the forms is the real world, like sunlight, while the sensible world is only imperfectly or partially real, like shadows. This Platonic realism, however, in denying that the eternal Forms are mental artifacts, differs sharply with modern forms of idealism.

The problem of universals—whether there are any and, if so, what exactly they are—was a dominant theme in ancient Greek philosophy, in medieval Scholasticism, and in Western philosophy during the modern period (the 17th through the 19th centuries). Although debates about universals no longer lead to fisticuffs (as they were said to do among the Scholastics), they remain central to contemporary metaphysics. Realists are still opposed by nominalists, and realists themselves are still sharply divided between those who adhere to something like Plato ’s conception of universals and those who favour Aristotle ’s. Realists also remain divided between those who posit a plenitude of universals and those who accept very few. This division in turn reflects a fundamental disagreement among realists over why one should believe in universals in the first place.
