οὐ γὰρ οἷόν τ᾽ ἐπιτηδεῦσαι τὰ τῆς ἀρετῆς ζῶντα βίον βάναυσον ἢ θητικόν. [1278α20. Aristotle, Politics.] (for it is not possible to pursue living a life of virtue as an artisan or serf.) “Serf” is thetes, wikipedia:
The thetes (Greek: θῆτες, thêtes, sing. θής, thēs, “serf”) were the lowest social class of citizens. The thetes were those who were workers for wages, or had less than 200 medimnoi (or their equivalent) as yearly income.
