§8.47.1Εἰ μὲν διά τι τῶν ἐκτὸς λυπῇ, οὐκ ἐκεῖνό σοι ἐνοχλεῖ, ἀλλὰ τὸ σὸν περὶ αὐτοῦ κρῖμα, τοῦτο δὲ ἤδη ἐξαλεῖψαι ἐπὶ σοί ἐστιν.
If you are pained by any external thing, it is not this that disturbs you, but your own judgment about it; and it is in your power to wipe out this judgment now.
εἰ δὲ λυπεῖ σέ τι τῶν ἐν τῇ σῇ διαθέσει, τίς ὁ κωλύων διορθῶσαι τὸ δόγμα;
But if anything in your own disposition pains you, who is there to prevent you from correcting your judgment?
ὁμοίως δὲ καὶ εἰ λυπῇ ὅτι οὐχὶ τόδε τι ἐνεργεῖς ὑγιές σοι φαινόμενον, τί οὐχὶ μᾶλλον ἐνεργεῖς ἢ λυπῇ; —ἀλλὰ ἰσχυρότερόν τι ἐνίσταται. —μὴ οὖν λυποῦ· οὐ γὰρ παρὰ σὲ ἡ αἰτία τοῦ μὴ ἐνεργεῖσθαι. —ἀλλὰ οὐκ ἄξιον ζῆν μὴ ἐνεργουμένου τούτου. —ἄπιθι οὖν ἐκ τοῦ ζῆν εὐμενής, ᾗ καὶ ὁ ἐνεργῶν ἀποθνῄσκει, ἅμα ἵλεως τοῖς ἐνισταμένοις.
And likewise, if you are pained because you are not doing this particular action which seems to you to be healthy, why do you not rather do it than be pained? — "But something more powerful stands in the way." — Then do not be pained; for the cause of its not being done does not lie with you. — "But life is not worth living if this is not done." — Depart then from life with a good will, in the same way as he who does perform it dies, and at the same time being well-disposed toward those who stand in your way.
