  The veridical reading, combined with the account that limits Forms to incomplete properties (See §6, supra), allows for the possibility that the philosopher can have knowledge of the visible realm. This can come about for at least two reasons. On the one hand, there will be a host of non-sensible properties and propositions about ordinary particulars and such properties, e.g., ‘Socrates is a man’. Since arguably Plato thinks that Socrates is completely or essentially a man, and since there is no Form of Man, the philosopher (and, perhaps, anyone) can know such a proposition. On the other hand, the philosopher, once he comes to know the Forms of the Incomplete Properties, can then have knowledge of the external world in any and all respects. Not misled by the compresent opposite properties, and able to base all his accounts on the Good and the other Forms, nothing stands in his way of knowing the material world  (520c).[23]
