  The predicative reading, on the other hand, lends itself to a defense of the Two Worlds account of Plato's metaphysics. The objects of belief and knowledge are distinct. Accordingly, one can have only beliefs about the particulars and about particulars only beliefs, and only knowledge of Forms and of Forms one can only have knowledge. It follows that knowledge cannot be any kind of justified true belief, not even one ‘tied down’ by the account of the appropriate cause. (See Meno 98a). Moreover, since one can have only knowledge of Forms, one cannot have any false beliefs about Forms. Given that in Book I of the Republic the interlocutors seem to have many false beliefs about Justice, e.g., that Justice is returning what is due, this consequence may be more worrisome than that which proscribes knowledge of the affairs of actual cities.
