Book 5, Chapter 34

Δύνασαι ἀεὶ εὐροεῖν, εἴ γε καὶ εὐοδεῖν, εἴ γε καὶ ὁδῷ ὑπολαμβάνειν καὶ πράσσειν. δύο ταῦτα κοινὰ τῇ τε τοῦ θεοῦ καὶ τῇ τοῦ ἀνθρώπου καὶ παντὸς λογικοῦ ζῴου ψυχῇ· τὸ μὴ ἐμποδίζεσθαι ὑπ’ ἄλλου καὶ τὸ ἐν τῇ δικαικῇ διαθέσει καὶ πράξει ἔχειν τὸ ἀγαθὸν καὶ ἐνταῦθα τὴν ὄρεξιν ἀπολήγειν.
