Platos Metaphysics Doctrine of Separationism (or Two Realms) Changing world of particular things characterized by identity and difference World of unchanging, immaterial, and eternal Forms.

The Forms Hypothetical entities designed to explain how numerically or quantitatively distinct things can be qualitatively identical. The Basic Argument 1. If identity in difference exists, then the Forms exist. 2. Identity in difference exists. So, 3. the Forms exist.
Beauty (f1) in Angelina and beauty (f2) in Helen are the same, but Angelina (A) and Helen (H) are not the same. Two numerically distinct things can only have identical properties if there are higher entities that make this possible. A is f1H is f2 F F must be distinct from f1 and f2, otherwise F could not be the same thing in f1 and f2. F must be identical with f1 and f2, otherwise there is no basis for saying that A and H have the same attribute.
The Forms are universal entities so other things can participate in their existence. The Forms are also concrete, for they are substances or things, though distinct from physical things. Individual physical things participate in the forms by having the natures of the forms.
