Chapter 34
Those things which differ in both, that is to say, in name and definition, may have one subject. In such a case they are called heteronymous, as are ascent and descent, for they have one subject—the incline. Or they may not have one subject; in which case, they are called different. Such are substance and accident, because they both have different names and different descriptions and they do not have one subject. The description of both of these, the heteronymous and the different, is this: Those things of which the name and the definition are diverse.
[20] {Περὶ ἑτέρων καὶ ἑτερωνύμων.} Τὰ δὲ κατ' ἄμφω ἤγουν τῷ ὀνόματι καὶ τῷ ὁρισμῷ διαφέροντα ἢ ἓν ὑποκείμενον ἔχουσι καὶ λέγεται ἑτερώνυμα ὡς ἀνάβασις καὶ κατάβασις, ἔχουσι γὰρ ἓν ὑποκείμενον, τὴν κλίμακα, ἢ οὐκ ἔχουσιν ἓν ὑποκείμενον καὶ λέγονται ἕτερα ὡς οὐσία καὶ συμβεβηκός: ταῦτα γὰρ καὶ ἕτερον ὄνομα ἔχουσι καὶ ἑτέραν ὑπογραφὴν καὶ οὐδὲ ἔχουσιν ἓν ὑποκείμενον. Τούτων δὲ ἀμφοτέρων, τῶν τε ἑτερωνύμων καὶ τῶν ἑτέρων, ὑπογραφὴ αὕτη: Ὧν τό τε ὄνομα καὶ ὁ ὅρος ἕτερος.
