Note 7 — Chapter XI · EUTHYPHRON.
Reading edition
Plato, Euthyphron, c. 6, p. 5 D. Among the various reasons (none of them valid in my judgment) given by Ueberweg (Untersuch. p. 251) for suspecting the authenticity of the Euthyphron, one is that τὸ ἀνόσιον is reckoned as an εἶδος as well as τὸ ὅσιον. Ueberweg seems to think this absurd, since he annexes to the word a note of admiration. But Plato expressly gives τὸ ἄδικον as an εἶδος, along with τὸ δίκαιον (Repub. v. 476 A); and one of the objections taken against his theory by Aristotle was, that it would assume substantive Ideas corresponding to negative terms — τῶν ἀποφάσεων ἰδέας. See Aristot. Metaphys. A. 990, b. 13, with the Scholion of Alexander, p. 565, a. 81, r.
