[194] Plut. Ibid. § 2: (Χρύσιππος) ἐν τοῖς ἕξεων οὐδὲν ἄλλο τὰς ἕξεις πλὴν ἀέρας εἶναί φησιν· ὑπὸ τούτων γὰρ συνέχεται τὰ σώματα, καὶ τοῦ ποιὸν ἕκαστον εἶναι αἴτιος ὁ συνέχων ἀήρ ἐστιν, ὃν σκληρότητα μὲν ἐν σιδήρῳ, πυκνότητα δ’ ἐν λίθῳ, λευκότητα δ’ ἐν ἀργύρῳ καλοῦσιν. Simpl. 69. γ: ἡ τῶν Στωϊκῶν δόξα λεγόντων, σώματα εἶναι τὰ σχήματα ὥσπερ τὰ ἄλλα ποιά. Ibid. 67, ε; 56, δ: πῶς δὲ καὶ πνευματικὴ ἡ οὐσία ἔσται τῶν σωματικῶν ποιοτήτων αὐτοῦ τοῦ πνεύματος συνθέτου ὄντος, κ.τ.λ. [195] Alex. Aphr. De An. 143, b: πῶς δὲ σωζόντων ἐστὶ τὴν περὶ κράσεως κοινὴν πρόληψιν τὸ λέγειν καὶ τὴν ἕξιν τοῖς ἔχουσιν αὐτὴν μεμίχθαι καὶ τὴν φύσιν τοῖς φυτοῖς καὶ τὸ φῶς τῷ ἀέρι καὶ τὴν ψυχὴν τῷ σώματι. Ibid. 144, α, the saying is quoted against the Stoics: μεμίχθαι τῇ ὕλῃ τὸν θεόν. [196] Plut. C. Not. 36, 3: λέγουσιν οὗτοι καὶ πλάττουσιν ἐπὶ μιᾶς οὐσίας δύο ἰδίως γενέσθαι ποίους (this follows from their hypothesis, but it is distinctly denied by Chrysippus in thesis. See p. 104, 2) καὶ τὴν αὐτὴν οὐσίαν ἕνα ποιὸν ἰδίως ἔχουσαν ἐπιόντος ἑτέρου δέχεσθαι καὶ διαφυλάττειν ὁμοίως ἀμφοτέρους. [197] Simpl. 70, ε: καὶ οἱ Στωϊκοὶ δὲ ποιότητας ποιοτήτων ποιοῦσιν ἑαυτῶν (? ἑκτῶν) ποιοῦντες ἑκτὰς ἕξεις [l. ἑκτὰ καὶ ἕξεις or ἕξεις only]. The context shows that the meaning of these words is that given above. The conception of a property is compounded of several attributes, and, therefore, a property of several subordinate properties. If λευκὸν is a χρῶμα, the διακριτικὸν ὄψεως is the ἕξις, or form of λευκὸν. [198] This follows of necessity, quite independently of the above-quoted language of Alexander, from the Stoic doctrine of the material nature of properties and of the mingling of materials. For if that intermingling of materials in which each one retains its properties (μῖξις and κρᾶσις in contrast to chemical combination παράθεσις and σύγχυσις) is defined to be the complete interpenetration of one material by another, without passing into a third (Stob. Ecl. i. 376; Alex. De Mixt. 142, a; Plut. C. Not. 37, 2); if, moreover, properties are said to be material; and in all cases when they are combined, each property retains its own peculiarity, and yet is inherent in the subject-matter and in every other property belonging to the same subject-matter; it follows that this relation can only be explained by supposing a mutual interpenetration of properties with each other and with their subject-matter. [199] The proof of this will be given subsequently. Meantime compare the remarks, p. 92, 2; 94, 1 on the λεκτόν.
