 In general, a Form F differs from an individual F thing in that F may be predicated univocally of the Form: The Form F is F. An individual F thing both is and is not F. In this sense the same property F can only be predicated equivocally of the individual (e.g. Republic 479a–c). Plato’s analysis of equivocally F individuals (Cratylus 439d–e, Symposium 211a) recalls observations that everyone makes about beautiful objects. They fade with time; require an offsetting ugly detail; elicit disagreements among observers; lose their beauty outside their context (adult shoes on children’s feet). Here beauty does better than most other properties at meeting the criteria for Forms and non-Forms. Odd numbers may fail to be odd in some hard-to-explain way, but the ways in which beautiful things fall short of their perfection are obvious even to the unphilosophical.
