Plato, Laws 633e

νῦν οὖν πότερα λέγομεν τὸν τῶν λυπῶν ἥττω κακὸν ἢ καὶ τὸν τῶν ἡδονῶν; μᾶλλον, ἔμοιγε δοκεῖ, τὸν τῶν ἡδονῶν· καὶ πάντες που μᾶλλον λέγομεν τὸν ὑπὸ τῶν ἡδονῶν κρατούμενον τοῦτον τὸν ἐπονειδίστως ἥττονα ἑαυτοῦ πρότερον ἢ τὸν ὑπὸ τῶν λυπῶν.

At present do we apply the term bad to the man who is inferior to pains, or to him also who is inferior to pleasures? To the man who is inferior to pleasures more than to the other, in my opinion. All of us, indeed, when we speak of a man who is shamefully self-inferior, mean one who is mastered by pleasures rather than one who is mastered by pains.
