GROTE'S PLATO.

could be possible; how we can think that which is not — a non-entity — any more than we can touch, or eat, or drink that which is not. It is surprising how often Plato returns to this perplexity. More than half the Sophistes is devoted to the discussion of it, merely in a parenthesis. As a specimen of the stumbling-blocks which the early metaphysical inquirers found in their path, as well as a striking example of the diversity of the points of view of different dialogues, we will quote a passage from Mr. Grote on this subject:[1]

“How is a false proposition possible? Many held that a false proposition and a false name were impossible, that you could not speak the thing that is not, or Non-Ens (τὸ μὴ ὄν): that such a proposition would be an empty sound, without meaning or signification; that speech may be significant or insignificant, but could not be false, except in the sense of being unmeaning. Now, this doctrine is dealt with in the Theætêtus, Sophistês, and Kratylus. In the Theætêtus, Sokratês examines it at great length, and proposes several different hypotheses to explain how a false proposition might be possible, but ends in pronouncing them all inadmissible. He declares himself incompetent, and passes onto something else. Again, in the Sophistês, the same point is taken up, and discussed there also very copiously. The Eleate in that dialogue ends by finding a solution which satisfies him — (viz., that τὸ μὴ ὄν = ιὸ ἕτερον τοῦ ὄντος). But what is remarkable is, that the solution does not meet any of the difficulties propounded in the Theætêtus; nor are these difficulties at all adverted to in the Sophistês. Finally, in the Kratylus, we have the very same doctrine, that false affirmations are impossible, — which both in the Theætêtus and in the Sophistès is enunciated, not as the decided opinion of the speaker, but as a problem which embarrasses him — we
