Book 1
1256a
But let us follow our normal method and investigate generally the nature of all kinds of property and the art of getting wealth, inasmuch as we saw the slave to be one division of property. In the first place therefore one might raise the question whether the art of getting wealth is the same as that of household management, or a part of it, or subsidiary to it; and if subsidiary, whether it is so in the sense in which the art of making shuttles is subsidiary to the art of weaving or in that in which the art of casting bronze is subsidiary to the making of statues (for the two are not subsidiary in the same way, but shuttle-making supplies tools whereas bronze-founding supplies material—and by material I mean the substance out of which certain work is produced, for example fleeces are material for a weaver and bronze for a statuary).
