Note A — Chapter I

For instance, in Plato’s “Parmenides,” where it is shown that the ideas are not in the mind. We may gather from what is there said that the ideas cannot be identified with any embodiment of them, however perfect, since an idea means a nature common to all its possible embodiments and remains always outside of them. This is what Plato meant by saying that the ideas lay apart from phenomena and were what they were in and for themselves. They were mere forms and not, as a materialised Platonism afterward fancied, images in the mind of some psychological deity. The gods doubtless know the ideas, as Plato tells us in the same place: these are the common object of their thought and of ours; hence they are not anybody’s thinking process, which of course would be in flux and phenomenal. Only by being ideal (i.e., by being a goal of intellectual energy and no part of sensuous existence) can a term be common to various minds and serve to make their deliverances pertinent to one another.

That truth is no existence might also be proved as follows: Suppose that nothing existed or (if critics carp at that phrase), that a universe did not exist. It would then be true that all existences were wanting, yet this truth itself would endure; therefore truth is not an existence. An attempt might be made to reverse this argument by saying that since it would still “be” true that nothing existed, the supposition is self-contradictory, for the truth would “be” or exist in any case. Truth would thus be turned into an opinion, supposed to subsist eternally in the ether. The argument, however, is a bad sophism, because it falsifies the intent of the terms used. Somebody’s opinion is not what is meant by the truth, since every opinion, however long-lived, may be false. Furthermore, the notion that it might have been true that nothing existed is a perfectly clear notion. The nature of dialectic is entirely corrupted when sincerity is lost. No intent can be self-contradictory, since it fixes its own object, but a man may easily contradict himself by wavering between one intent and another.
