Plato, Laws 635d

ἡδονὰς ταὐτὸν πείσονται τοῖς ἡττωμένοις τῶν φόβων· δουλεύσουσι τρόπον ἕτερον καὶ ἔτʼ αἰσχίω τοῖς γε δυναμένοις καρτερεῖν ἐν ταῖς ἡδοναῖς καὶ τοῖς κεκτημένοις τὰ περὶ τὰς ἡδονάς, ἀνθρώποις ἐνίοτε παντάπασι κακοῖς, καὶ τὴν ψυχὴν τῇ μὲν δούλην τῇ δὲ ἐλευθέραν ἕξουσιν, καὶ οὐκ ἄξιοι ἁπλῶς ἀνδρεῖοι καὶ ἐλευθέριοι ἔσονται προσαγορεύεσθαι. σκοπεῖτε οὖν εἴ τι τῶν νῦν λεγομένων ὑμῖν κατὰ τρόπον δοκεῖ λέγεσθαι.

because of the natural attraction of pleasures, they will suffer the same fate as those who are worsted by fears: they will, that is to say, in another and still more shameful fashion be enslaved by those who are able to hold out amidst pleasures and those who are versed in the art of pleasure,—people who are sometimes wholly vicious: thus their condition of soul will be partly enslaved and partly free, and they will not deserve to be called, without qualification, free men and men of courage. Consider, then, whether you at all approve these remarks of mine.
