Thus for Plato abstractions are supernatural existents. They are nonmaterial entities in another dimension, independent of man's mind and of any of their material embodiments. The Forms, Plato tells us repeatedly, are what is really real. The particulars they subsume-the concretes that make up this world-are not; they have only a shadowy, dreamlike half-reality. Momentous conclusions about man are implicit in this metaphysics {and were later made explicit by a long line of Platonists}: since individual men are merely particular instances of the universal "man," they are not ultimately real. What is real about men is only the Form which they share in common and reflect.
