In other words, the Forms are universals given as a solution to the problem of universals, or the problem of "the One and the Many", e. g. how one predicate "red" can apply to many red objects. For Plato this is because there is one abstract object or Form of red, redness itself, in which the several red things "participate". As Plato's solution is that universals are Forms and that Forms are real if anything is, Plato's philosophy is unambiguously called Platonic realism. According to Aristotle, Plato's best known argument in support of the Forms was the "one over many" argument.
