Should you be willing to read [Xenophon's Anabasis] very carefully you shall discover how [. . .] to deceive one’s enemies to their harm and one’s friends to their advantage, and to speak the truth in a way that will not pain those who are needlessly disturbed by it.
εἰ γοῦν ἐθελήσειας αὐτοῦ τῇ περὶ τὴν Ἀνάβασιν πραγματεία σφόδρα ἐπιμελῶς ἐντυχεῖν, [. . .] εὑρήσεις [. . .] καὶ ἐξαπατῆσαι ὅπως πολεμίους μὲν ἐπὶ βλάβῃ, φίλους δ᾿ ἐπὶ τῷ συμφέροντι, καὶ μάτην ταραττομένοις ἀλύπως τἀληθὲς καὶ πιστῶς εἰπεῖν.
