the lives of the herdsman, the brigand, the fisherman, the hunter, the husband-man. Others also live pleasantly by combining some of these pursuits, supplementing the more deficient life where it happens to fall short in regard to being self-sufficing: for instance, some combine a pastoral life and brigandage, others husbandry and hunting, and similarly with the others—they pass their time in such a combination of pursuits as their need compels. Property of this sort then seems to be bestowed by nature herself upon all, as immediately upon their first coming into existence, so also when they have reached maturity. For even at the original coming into existence of the young some kinds of animals bring forth with them at birth enough sustenance to suffice until the offspring can provide for itself, for example all the species that bear their young in the form of larvae or in eggs. The viviparous species have sustenance for their offspring inside themselves for a certain period, the substance called milk. So that clearly we must suppose that nature also provides for them in a similar way when grown up, and that plants exist for the sake of animals and the other animals for the good of man, the domestic species both for his service and for his food, and if not all at all events most of the wild ones for the sake of his food and of his supplies of other kinds, in order thatthey may furnish him both with clothing and with other appliances. If therefore nature makes nothing without purpose or in vain, it follows that nature has made all the animals for the sake of men. Hence even the art of war will by nature be in a manner an art of acquisition (for the art of hunting is a part of it) that is properly employed both against wild animals and against such of mankind as though designed by nature for subjection refuse to submit to it, inasmuch as this warfare is by nature just.
