Note 43 — Chapter IV · AUTHORITIES FOR THE STOIC PHILOSOPHY: ITS PROBLEM AND DIVISIONS.

According to Diog. 40, the first place was assigned to Logic, the second to Science, the third to Ethics, by Zeno, Chrysippus, Archedemus, Eudemus, and others. The same order, but inverted, is found in Diogenes of Ptolemais, and in Seneca, Ep. 89, 9. The latter, however, observes (Nat. Qu. Prol. 1) that the difference between that part of philosophy which treats about God, and that which treats about man, is as great as the difference between philosophy and other departments, or even as between God and man. On the other hand, Apollodorus places Ethics in the middle, as also Cleanthes does, and likewise Panætius and Posidonius, if it is certain that they began with science. This appears, however, only to have reference to their order in discussion (see Sext. Math. vii. 22, probably on the authority of Posidonius). A few (Diog. 40) asserted that the parts could be so little separated, that they must be always treated together. The statement of Chrysippus (in Plut. Sto. Rep. 9, 1), that Logic must come first, and be followed by Ethics and Science, so that the theological part may form the conclusion, only refers to the order in which they ought to be taught. ↑
