Plato, Meno 78a

ἀνάγκη. ἀλλὰ τοὺς βλαπτομένους οὗτοι οὐκ οἴονται ἀθλίους εἶναι καθʼ ὅσον βλάπτονται; καὶ τοῦτο ἀνάγκη. τοὺς δὲ ἀθλίους οὐ κακοδαίμονας; οἶμαι ἔγωγε. ἔστιν οὖν ὅστις βούλεται ἄθλιος καὶ κακοδαίμων εἶναι; οὔ μοι δοκεῖ, ὦ Σώκρατες. οὐκ ἄρα βούλεται, ὦ Μένων, τὰ κακὰ οὐδείς, εἴπερ μὴ βούλεται τοιοῦτος εἶναι. τί γὰρ ἄλλο ἐστὶν ἄθλιον εἶναι ἢ ἐπιθυμεῖν τε τῶν κακῶν καὶ κτᾶσθαι; κινδυνεύεις

But do they not hold that those who are harmed are miserable in proportion to the harm they suffer? That too must be. And are not the miserable ill-starred? I think so. Then is there anyone who wishes to be miserable and ill-starred? I do not suppose there is, Socrates. No one, then, Meno, desires evil, if no one desires to be such an one: for what is being miserable but desiring evil and obtaining it?
