For what do you desire more than to do a person good?

(Loeb, translation Haines. Book 9, 42,4) —

But above all, when thou findest fault with a man for faithlessness and ingratitude, turn thy thoughts to thyself. For evidently that fault is thine own, whether thou hadst faith that a man with such a character would keep faith with thee, or if in bestowing a kindness thou did not bestow it absolutely and as from the very doing of having at once received the full complete fruit. For when thou hast done a kindness, what more would thou have?

Greek:

μάλιστα δέ, ὅταν ὡς ἀπίστῳ ἢ ἀχαρίστῳ μέμφῃ, εἰς σεαυτὸν ἐπιστρέφου: προδήλως γὰρ σὸν τὸ ἁμάρτημα, εἴτε περὶ τοῦ τοιαύτην τὴν διάθεσιν ἔχοντος ἐπίστευσας ὅτι τὴν πίστιν φυλάξει, εἴτε τὴν χάριν διδοὺς μὴ καταληκτικῶς ἔδωκας μηδὲ ὥστε ἐξ αὐτῆς τῆς πράξεως εὐθὺς ἀπειληφέναι πάντα τὸν καρπόν. τί γὰρ πλέον θέλεις εὖ ποιήσας ἄνθρωπον;
