εἰσὶ δὲ αἱ μαρτυρίαι αἱ μὲν περὶ αὑτοῦ αἱ δὲ περὶ τοῦ ἀμφισβητοῦντος, καὶ αἱ μὲν περὶ τοῦ πράγματος αἱ δὲ περὶ τοῦ ἤθους, ὥστε φανερὸν ὅτι οὐδέποτʼ ἔστιν ἀπορῆσαι μαρτυρίας χρησίμης· εἰ μὴ γὰρ κατὰ τοῦ πράγματος ἢ αὑτῷ ὁμολογουμένης ἢ τῷ ἀμφισβητοῦντι ἐναντίας, ἀλλὰ περὶ τοῦ ἤθους ἢ αὑτοῦ εἰς ἐπιείκειαν ἢ τοῦ ἀμφισβητοῦντος εἰς φαυλότητα. τὰ δʼ ἄλλα περὶ μάρτυρος, ἢ φίλου ἢ ἐχθροῦ ἢ μεταξύ, ἢ εὐδοκιμοῦντος ἢ ἀδοξοῦντος ἢ μεταξύ, καὶ ὅσαι ἄλλαι τοιαῦται διαφοραί, ἐκ τῶν αὐτῶν τόπων λεκτέον ἐξ οἵων περ καὶ τὰ ἐνθυμήματα λέγομεν. περὶ δὲ τῶν συνθηκῶν τοσαύτη τῶν λόγων χρῆσίς ἐστιν ὅσον αὔξειν ἢ καθαιρεῖν, ἢ πιστὰς ποιεῖν ἢ ἀπίστους— ἐὰν μὲν αὐτῷ ὑπάρχωσι, πιστὰς καὶ κυρίας, ἐπὶ δὲ τοῦ ἀμφισβητοῦντος τοὐναντίον.
