Note 42 — Chapter IV · AUTHORITIES FOR THE STOIC PHILOSOPHY: ITS PROBLEM AND DIVISIONS.
Oswald J. (Oswald Joseph) Reichel translation
Diog. 39: τριμερῆ φασιν εἶναι τὸν κατὰ φιλοσοφίαν λόγον· εἶναι γὰρ αὐτοῦ τὸ μέν τι φυσικὸν, τὸ δὲ ἠθικὸν, τὸ δὲ λογικόν. οὕτω δὲ πρῶτος διεῖλε Ζήνων ὁ Κιτιεὺς ἐν τῷ περὶ λόγου καὶ Χρύσιππος ἐν τῷ αʹ περὶ λόγου καὶ ἐν τῇ αʹ τῶν φυσικῶν, καὶ Ἀπολλόδωρος ὁ Ἔφιλλος ἐν τῷ πρώτῳ τῶν εἰς τὰ δόγματα εἰσαγωγῶν, καὶ Εὔδρομος ἐν τῇ ἠθικῇ στοιχειώσει, καὶ Διογένης ὁ Βαβυλώνιος, καὶ Ποσειδώνιος. Sext. Math. vii. 16. Sen. Ep. 89, 9; 14. The six divisions enumerated by Cleanthes (Diog. 41)—Dialectic, Rhetoric, Ethics, Politics, Physics, Theology (Diog. 41) may be easily reduced to three. ↑
