Note 41 — Chapter XIV · THE STOIC PHILOSOPHY AS A WHOLE AND ITS HISTORICAL POSITION.
Oswald J. (Oswald Joseph) Reichel translation
Diog. 33: καὶ τὸ δοξαστὸν ἀπὸ προτέρου τινὸς ἐναργοῦς ἤρτηται … τὴν δὲ δόξαν καὶ ὑπόληψιν λέγουσιν. ἀληθῆ τέ φασι καὶ ψευδῆ· ἂν μὲν γὰρ ἐπιμαρτυρῆται ἢ μὴ ἀντιμαρτυρῆται ἀληθῆ εἶναι· ἐὰν δὲ μὴ ἐπιμαρτυρῆται ἢ ἀντιμαρτυρῆται ψευδῆ τυγχάνειν. Sext. Math. vii. 211: τῶν δοξῶν κατὰ τὸν Ἐπίκουρον αἱ μὲν ἀληθεῖς εἰσιν αἱ δὲ ψευδεῖς· ἀληθεῖς μὲν αἵ τε ἀντιμαρτυρούμεναι καὶ οὐκ ἀντιμαρτυρούμεναι πρὸς τῆς ἐναργείας, ψευδεῖς δὲ αἵ τε ἀντιμαρτυρούμεναι καὶ οὐκ ἐπιμαρτυρούμεναι πρὸς τῆς ἐναργείας. Ritter, iii. 486, observes that these statements are contradictory. According to Sextus, an opinion is only then true when it can be proved and not refuted; according to Diogenes, when it can be proved or not refuted. The latter is, however, clearly meant by Sextus, and is affirmed by Epicurus in Diog. 50 and 51. ↑
