[525]. Unless this is implied in κτήματος, 1257a6, as ἔστι γὰρ ἡ μεταβλητικὴ πάντων (14 f.) might seem to indicate. Zmavc (Archiv., etc., p. 410) points to 1253b33-39, on the automatic tripods of Hephaestus, as implying it, but if so it was unintended by Aristotle. But cf. infra, pp. [84] and [86], n. 4, where it is recognized.
[526]. 1257a11; 5-19, but not specifically stated, and the term χρεία does not occur here.
[527]. i. 7. 14: καὶ τὸ σπανιώτερον τοῦ ἀφθόνου, οἷον χρυσὸς σιδήρου ἀχρηστότερος ὤν· ἄλλον δὲ τρόπον τε ἄφθονον τοῦ σπανίου, ὅτι ἡ χρῆσις ὑπερέχει· τὸ γὰρ πολλάκις τοῦ ὀλιγάκις ὑπερέχει· ὅθεν λέγεται ἄριστον μὲν ὕδωρ. Cf. Pind. Ol. i. 1 and Cope-Sandys ed. of Ar. Rhet. (I, pp. 130 f., 1877).
[528]. Ibid.
[529]. V, v. 8-14. 1133a5-1133b10 ff.
[530]. E.g., Stewart.
[531]. 1133a5-12; 15 f.; 18; cf. Eud. Eth. vii. 10. 1243b28-38.
[532]. N. Eth. 1133a5-12, etc., 12 f.: οὐθὲν γὰρ κωλύει κρεῖττον εἶναι το θατέρου ἔργον ἢ τὸ θατέρου. The emphasis seems to be on quality of labor, as suggested by κρεῖττον. Cf. both ὅσον and οἷον (15) and p. [84] n. 3.
[533]. Ibid. 7-10; by joining means and extremes together, the proportionate exchange is effected. Cf. also 1133b4 ff.; 1133a32 f. As observed by Ritchie (Palgrave’s Dictionary, art. “Aristotle”) and H. Sewall (op. cit., p. 3, n. 2), the proportion is clearer to moderns if we make our standard one hour of labor of each workman instead of the men themselves.
[534]. Stewart (Notes to N. Eth. I, 449) suggests that this gives what the economists call “natural value,” but that the market value oscillates from this because of supply and demand.
