Note 30 — Chapter X · ETHICS. THE GENERAL PRINCIPLES OF THE STOIC ETHICS. ABSTRACT THEORY OF MORALITY.
Oswald J. (Oswald Joseph) Reichel translation
Diog. 107: καθῆκον φασὶν εἶναι ὃ πραχθὲν εὔλογόν τιν’ ἴσχει ἀπολογισμὸν οἷον τὸ ἀκόλουθον ἐν τῇ ζωῇ (the same in Cicero), ὅπερ καὶ ἐπὶ τὰ φυτὰ καὶ ζῷα διατείνει· ὁρᾶσθαι γὰρ κἀπὶ τούτων καθήκοντα. Stob. 158: ὁρίζεται δὲ τὸ καθῆκον τὸ ἀκόλουθον ἐν ζωῇ, ὃ πραχθὲν εὔλογον ἀπολογίαν ἔχει· παρὰ τὸ καθῆκον δὲ ἐναντίως. τοῦτο διατείνει καὶ εἰς τὰ ἄλογα τῶν ζῴων, ἐνεργεῖ γὰρ τι κἀκεῖνα ἀκολούθως τῇ ἑαυτῶν φύσει· ἐπὶ δὲ τῶν λογικῶν ζῴων οὕτως ἀποδίδοται, τὸ ἀκόλουθον ἐν βίῳ. καθῆκον is, in general, what is according to nature, with which ἀκόλουθον coincides. (See p. 228, 2.) See Diog. 108: ἐνέργημα δ’ αὐτὸ [τὸ καθῆκον] εἶναι ταῖς κατὰ φύσιν κατασκευαῖς οἰκεῖον. ↑
