CHAPTER IX There is also another species of acquisition which they [1257a] particularly call pecuniary, and with great propriety; and by this indeed it seems that there are no bounds to riches and wealth. Now many persons suppose, from their near relation to each other, that this is one and the same with that we have just mentioned, but it is not the same as that, though not very different; one of these is natural, the other is not, but rather owing to some art and skill; we will enter into a particular examination of this subject. The uses of every possession are two, both dependent upon the thing itself, but not in the same manner, the one supposing an inseparable connection with it, the other not; as a shoe, for instance, which may be either worn, or exchanged for something else, both these are the uses of the shoe; for he who exchanges a shoe with some man who wants one, for money or provisions, uses the shoe as a shoe, but not according to the original intention, for shoes were not at first made to be exchanged. The same thing holds true of all other possessions; for barter, in general, had its original beginning in nature, some men having a surplus, others too little of what was necessary for them: hence it is evident, that the selling provisions for money is not according to the natural use of things; for they were obliged to use barter for those things which they wanted; but it is plain that barter could have no place in the first, that is to say, in family society; but must have begun when the number of those who composed the community was enlarged: for the first of these had all things in common; but when they came to be separated they were obliged to exchange with each other many different things which both parties wanted. Which custom of barter is still preserved amongst many barbarous nations, who procure one necessary with another, but never sell anything; as giving and receiving wine for corn and the like. This sort of barter is not contradictory to nature, nor is it any species of money-getting; but is necessary in procuring that subsistence which is so consonant thereunto. But this barter introduced the use of money, as might be expected; for a convenient place from whence to import what you wanted, or to export what you had a surplus of, being often at a great distance, money necessarily made its way into commerce; for it is not everything which is naturally most useful that is easiest of carriage; for which reason they invented something to exchange with each other which they should mutually give and take, that being really valuable itself, should have the additional advantage of being of easy conveyance, for the purposes of life, as iron and silver, or anything else of the same nature: and this at first passed in value simply according to its weight or size; but in process of time it had a certain stamp, to save the trouble of weighing, which stamp expressed its value.
