If there are no additional benefits, what good is this justification. Philebus 58dd, and Timaeus 27d ff. The problem is, as Socrates says, that we would need to posit another aviary to explain how the judgment-maker mistakes a piece of ignorance for a piece of knowledge. This owes its impetus to a desire to read Plato as charitably as possible, and a belief that a charitable reading of Plato's works will minimise their dependence on the theory of Forms.

Heracliteanism shows that "Nothing is in itself just one thing A belief is accurate if and only if it is true.
