The Phaedo, despite the central role which the theory of Forms occupies there, gives us little explicit information. We meet with stock examples and with generalizations like "everything which belongs to being", "everything to which we give the mark of ‘that which is’ in our discussions", "all this sort of being". Socrates postulates the existence of the beautiful itself, the good itself, the large itself, and "all the rest", and he explains the beauty of beautiful things by appealing to their (...) participation in beauty, stressing that he means that for "everything".

The reply which Socrates makes to Zeno in the Parmenides and that which he makes to the φιλοθμονς in the Republic are perhaps connected chiefly by the fact that a false interpretation of either might prejudice the other, but it seems convenient to take them together for that reason even if they have not much actual connection in themselves. Both are controversial, and in the case of Socrates' reply to Zeno, no re-statement of it could be secure which did not (...) take account of Parmenides' reply to Socrates. For if Parmenides, as is maintained by some, is not attacking the doctrine of forms as such, but only Socratic theories of their relation with particulars, it would be natural to think that these theories about ‘participation’ had been the substance of Socrates' answer to Zeno. So it is impossible to avoid some discussion of the later passage, however cursory, as a preliminary. (shrink)

This distinction has sometimes been read as purely epistemic, resting not on things, but on our knowledge of them: there is one world, not two, though it may be apprehended in two ways. But this view is patently at odds with the text. Knowledge and opinion are δυνάμεις, "faculties," to be distinguished and defined by their objects, no less than by the state of mind they produce, and Plato clearly states that the fallibility and unclearness of opinion is rooted in (...) the relative unreality of opinables.
