Besides St. Hilaire and Zmavc, cited above, among those favorable are Cossa, _Hist. des doctrines economiques_, p. 149; Blanqui, _op. cit._, I, 49, 86. More reserved are Souchon, _op. cit._, p. 127; DuBois, _op. cit._, p. 50; Haney, _op. cit._, pp. 47 f.; unfair interpretation, Dühring, _op. cit._, pp. 20 f. Footnote 522: i. 9. 1257_a_6-9: ἑκάστου γὰρ κτήματος διττὴ ἡ χρῆσίς ἐστιν ἀμφότεραι δὲ καθ᾽ αὑτὸ μὲν ἀλλ᾽ οὐχ ὁμοίως καθ᾽ αὑτό, ἀλλ᾽ ἡ μὲν οἰκεία ἡ δ᾽ οὐκ οἰκεία τοῦ πράγματος οἱον ὑποδήματος ἥ τε ὑπόδεσις καὶ ἡ μεταβλητική. Footnote 523: _Wealth of Nations_, I, chap. iv. Footnote 524: Cf. Souchon, _op. cit._, p. 127; Haney, _op. cit._, p. 47. Footnote 525: Unless this is implied in κτήματος, 1257_a_6, as ἔστι γὰρ ἡ μεταβλητικὴ πάντων (14 f.) might seem to indicate. Zmavc (_Archiv._, etc., p. 410) points to 1253_b_33-39, 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. Footnote 526: 1257_a_11; 5-19, but not specifically stated, and the term χρεία does not occur here. Footnote 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). Footnote 528: _Ibid._ Footnote 529: V, v. 8-14. 1133_a_5-1133_b_10 ff. Footnote 530: E.g., Stewart. Footnote 531: 1133_a_5-12; 15 f.; 18; cf. _Eud. Eth._ vii. 10. 1243_b_28-38. Footnote 532: _N. Eth._ 1133_a_5-12, 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. Footnote 533: _Ibid._ 7-10; by joining means and extremes together, the proportionate exchange is effected. Cf. also 1133_b_4 ff.; 1133_a_32 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. Footnote 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. Footnote 535: 1133_a_25-27; 1133_b_6 f. Cf. p. 34, n. 5, for Plato’s use of the term. Footnote 536: _Op. cit._, pp. 47 f. Footnote 537: Cf. the discussion and notes above; also 1133_a_15 f., where both elements seem to be recognized, though the meaning of the passage is disputed. Cf. _infra_, p. 108, n. 3. Footnote 538:
