Note 20 — Chapter XIV · THE STOIC PHILOSOPHY AS A WHOLE AND ITS HISTORICAL POSITION.
Oswald J. (Oswald Joseph) Reichel translation
Diog. 29: διαιρεῖται τοίνυν [ἡ φιλοσοφία] εἰς τρία, τό τε κανονικὸν καὶ φυσικὸν καὶ ἠθικόν. Canonic was also called περὶ κριτηρίου καὶ ἀρχῆς καὶ στοιχειωτικόν; natural science, περὶ γενέσεως καὶ φθορᾶς καὶ περὶ φύσεως; ethics, περὶ αἱρετῶν καὶ φευκτῶν καὶ περὶ βίων καὶ τέλους. ↑
