[120] Diog. 43: τὴν διαλεκτικὴν διαιρεῖσθαι εἴς τε τὸν περὶ τῶν σημαινομένων καὶ τῆς φωνῆς τόπον. Ibid. 62: τυγχάνει δ’ αὕτη, ὡς ὁ Χρύσιππός φησι, περὶ σημαίνοντα καὶ σημαινόμενα. Seneca l.c.: διαλεκτικὴ in duas partes dividitur, in verba et significationes, i.e. in res, quæ dicuntur, et vocabula, quibus dicuntur. The distinction between τὸ σημαῖνον and τὸ σημαινόμενον, to which τὸ τυγχάνον (the real object) must be added as a third, will be hereafter discussed in another place. A much narrower conception of dialectic, and more nearly approaching to that of the Peripatetics, is to be found in the definition given by Sext. Pyrrh. ii. 213. The division there given is also found in the Platonist Alcinous, Isag. c. 3, as Fabricius has pointed out. It appears, therefore, not to belong to the Stoic School, but, at most, to a few of its later members. [121] Seneca continues: Ingens deinde sequitur utriusque divisio, without, however, giving it. [122] There is much which is open to doubt in Petersen’s attempt (Phil. Chrys. Fund. 221) to settle these divisions. At the very beginning, his reference of the words in Sext. Math. viii. 11 to the parts of logic is unhappy. Nicolai (De Logic. Chrys. Lib. 21) has acted with greater caution, but even much of what he says is doubtful. [123] Diog. 55. [124] Diog. 44: εἶναι δὲ τῆς διαλεκτικῆς ἴδιον τόπον καὶ τὸν προειρημένον περὶ αὐτῆς τῆς φωνῆς, ἐν ᾧ δείκνυται ἡ ἐγγράμματος φωνὴ καὶ τίνα τὰ τοῦ λόγου μέρη, καὶ περὶ σολοικισμοῦ καὶ βαρβαρισμοῦ καὶ ποιημάτων καὶ ἀμφιβολιῶν καὶ περὶ ἐμμελοῦς φωνῆς καὶ περὶ μουσικῆς καὶ περὶ ὅρων κατά τινας καὶ διαιρέσεων καὶ λέξεων. The theory of the determination and division of conceptions occupies such an important place in the section περὶ φωνῆς, that we might feel disposed to suppose some mistake in the authority. Still, from the later authorities, pp. 60–62, it is seen that by many it is usually so represented.
