Note 58 — Chapter IV · DE INTERPRETATIONE.
Reading edition
Ibid. p. 257, B: Οὐκ ἀρ’, ἐναντίον ὅταν ἀπόφασις λέγηται σημαίνειν, συγχωρησόμεθα, τοσοῦτον δὲ μόνον, ὅτι τῶν ἄλλων τι μηνύει τὸ μὴ καὶ τὸ οὔ προτιθέμενα τῶν ἐπιόντων ὀνομάτων, μᾶλλον δὲ τῶν πραγμάτων, περὶ ἅττ’ ἂν κέηται τὰ ἐπιφθεγγόμενα ὕστερον τῆς ἀποφάσεως ὀνόματα.
The term ἀντίφασις, and its derivative ἀντιφατικῶς, are not recognized in the Platonic Lexicon. Compare the same dialogue, Sophistes, p. 263; also Euthydêmus, p. 298, A. Plato does not seem to take account of negative propositions as such. See ‘Plato and the Other Companions of Sokrates,’ vol. II. ch. xxvii. pp. 446-455.
