[1256a] As a slave is a particular species of property, let us by all means inquire into the nature of property in general, and the acquisition of money, according to the manner we have proposed. In the first place then, some one may doubt whether the getting of money is the same thing as economy, or whether it is a part of it, or something subservient to it; and if so, whether it is as the art of making shuttles is to the art of weaving, or the art of making brass to that of statue founding, for they are not of the same service; for the one supplies the tools, the other the matter: by the matter I mean the subject out of which the work is finished, as wool for the cloth and brass for the statue. It is evident then that the getting of money is not the same thing as economy, for the business of the one is to furnish the means of the other to use them; and what art is there employed in the management of a family but economy, but whether this is a part of it, or something of a different species, is a doubt; for if it is the business of him who is to get money to find out how riches and possessions may be procured, and both these arise from various causes, we must first inquire whether the art of husbandry is part of money-getting or something different, and in general, whether the same is not true of every acquisition and every attention which relates to provision. But as there are many sorts of provision, so are the methods of living both of man and the brute creation very various; and as it is impossible to live without food, the difference in that particular makes the lives of animals so different from each other. Of beasts, some live in herds, others separate, as is most convenient for procuring themselves food; as some of them live upon flesh, others on fruit, and others on whatsoever they light on, nature having so distinguished their course of life, that they can very easily procure themselves subsistence; and as the same things are not agreeable to all, but one animal likes one thing and another another, it follows that the lives of those beasts who live upon flesh must be different from the lives of those who live on fruits; so is it with men, their lives differ greatly from each other; and of all these the shepherd's is the idlest, for they live upon the flesh of tame animals, without any trouble, while they are obliged to change their habitations on account of their flocks, which they are compelled to follow, cultivating, as it were, a living farm. Others live exercising violence over living creatures, one pursuing this thing, another that, these preying upon men; those who live near lakes and marshes and rivers, or the sea itself, on fishing, while others are fowlers, or hunters of wild beasts; but the greater part of mankind live upon the produce of the earth and its cultivated fruits; and the manner in which all those live who follow the direction of nature, and labour for their own subsistence, is nearly the same, without ever thinking to procure any provision by way of exchange or merchandise, such are shepherds, husband-men, [1256b] robbers, fishermen, and hunters: some join different employments together, and thus live very agreeably; supplying those deficiencies which were wanting to make their subsistence depend upon themselves only: thus, for instance, the same person shall be a shepherd and a robber, or a husbandman and a hunter; and so with respect to the rest, they pursue that mode of life which necessity points out. This provision then nature herself seems to have furnished all animals with, as well immediately upon their first origin as also when they are arrived at a state of maturity; for at the first of these periods some of them are provided in the womb with proper nourishment, which continues till that which is born can get food for itself, as is the case with worms and birds; and as to those which bring forth their young alive, they have the means for their subsistence for a certain time within themselves, namely milk. It is evident then that we may conclude of those things that are, that plants are created for the sake of animals, and animals for the sake of men; the tame for our use and provision; the wild, at least the greater part, for our provision also, or for some other advantageous purpose, as furnishing us with clothes, and the like. As nature therefore makes nothing either imperfect or in vain, it necessarily follows that she has made all these things for men: for which reason what we gain in war is in a certain degree a natural acquisition; for hunting is a part of it, which it is necessary for us to employ against wild beasts; and those men who being intended by nature for slavery are unwilling to submit to it, on which occasion such a. war is by nature just: that species of acquisition then only which is according to nature is part of economy; and this ought to be at hand, or if not, immediately procured, namely, what is necessary to be kept in store to live upon, and which are useful as well for the state as the family. And true riches seem to consist in these; and the acquisition of those possessions which are necessary for a happy life is not infinite; though Solon says otherwise in this verse:

for they may be fixed as in other arts; for the instruments of no art whatsoever are infinite, either in their number or their magnitude; but riches are a number of instruments in domestic and civil economy; it is therefore evident that the acquisition of certain things according to nature is a part both of domestic and civil economy, and for what reason.
