[102] In the following passage Xenophon develops money in its specific forms of money and hoard: “ἐν μόνω τούτῳ ὦν ἐγω οἴδα ἔργων οὐδὲ φθονεῖ οὐδεις τοῖς ἐπισκευαζομένοις ... ἀργυρῖτις δὲ ὅσω ἄν πλείων φαίνηται, καὶ ἀργύριον πλεῖον γίγνηται, τοσούτῳ πλείονες ἐπί τὸ ἔργον τοῦτο ἔρχονται ... καὶ γὰρ δὴ ἔπιπλα μὲν ἐπειδὰν ἰκανά τις κτήσηται τῇ οἰκίᾳ, οὐ μάλα ἔἱτι προσωνοῦνται· ἀργύριον δὲ οὐδείς πω οὔτω πολὺ ἐκτήσατο ὥστε μὴ ἔτι προσθεῖσθαι, ἀλλ’ ἤν τισι γένηται παμπληθὲς, τὸ περιττεῦον κατορύττοντες οὐδὲν ἥττον ἥδονται ἥ χρώμενοι αὐτᾠ· καὶ μὲν ὅταν γε εὗ πράττωσιν αἰ πόλεις ἰσχυρῶς, οἰ ἄνθρωποι ἀργυρίου δέονται. Οἰ μὲν γὰρ ἄνδρες ἀμφι ὅπλα τε καλὰ καὶ ἵππους ἀγαρθοὺς καὶ οἰκίας καὶ κατασκευὰς μεγαλοπρεπεῖς βοὐλονται δαπανᾶν, αἰδὲ γυναῖκες εἰς ἐσθῆτα πολυτελῆ καὶ χρυσοῦν κόσμον τρέπονται· ὅταν δε αὔ νοσήσωσι πόλεις ἠ ἀφορίαις καρπῶν ῆ πολέμω ἔτι καὶ πολὺ μἄλλον τῆς γῆς ἀρυοῦ γιγνομενης καὶ εἰς ἐπιτήδεια καὶ εἰς ἐπικουροὺς νομίσματος δέονται.” (Xen. de Vectigalibus, c. IV.) (“Of all operations with which I am acquainted, this is the only one in which no sort of jealousy is felt at a further development of the industry ... the larger the quantity of ore discovered and the greater the amount of silver extracted, the greater the number of persons ready to engage in the operation.... No one when he has got sufficient furniture for his house dreams of making further purchases on this head, but of silver no one ever yet possessed so much that he was forced to cry “Enough.” On the contrary, if ever anybody does become possessed of an immoderate amount he finds as much pleasure in digging a hole in the ground and hoarding it as an actual employment of it.... When a state is prosperous there is nothing which people so much desire as silver. The men want money to expend on beautiful armor and fine horses, and houses and sumptuous paraphernalia of all sorts. The women betake themselves to expensive apparel and ornaments of gold. Or when states are sick, either through barrenness of corn and other fruits, or through war, the demand for current coin is even more imperative (whilst the ground lies unproductive), to pay for necessaries or military aid.” Transl. by H. G. Dakyns, London, 1892, v. 2, Revenues, p. 335-336.) Aristotle develops in Book I., ch. 9 of his Politics the two opposite movements of circulation. C-M-C and M-C-M, calling them “economics” and “chrematistics” respectively. The two forms are represented by the Greek tragedian Euripides as Sikn (right) and Keodos (profit). [103] Of course, capital also is advanced in the shape of money, and the money thus advanced may be advanced capital, but this point of view does not fall within the horizon of simple circulation. [104] “The difference between the means of purchase and the means of payment” is emphasized by Luther.
