Having determined thus far, it remains that we consider whether all these different employments shall be open to all; for it is possible to continue the same persons always husbandmen, artificers, judges, or counsellors; or shall we appoint different persons to each of those employments which we have already mentioned; or shall some of them be appropriated to particulars, and others of course common to all? but this does not take place in every state, for, as we have already said, it is possible that all may be common to all, or not, but only common to some; and this is the difference between one government and another: for in democracies the whole community partakes of everything, but in oligarchies it is different.

Since we are inquiring what is the best government possible, and it is admitted to be that in which the citizens are happy; and that, as we have already said, it is impossible to obtain happiness without virtue; it follows, that in the best-governed states, where the citizens are really men of intrinsic and not relative goodness, none of them should be permitted to exercise any mechanic employment or follow merchandise, as being ignoble and destructive to virtue; neither should they be husband-[1329a] men, that they may be at leisure to improve in virtue and perform the duty they owe to the state. With respect to the employments of a soldier, a senator, and a judge, which are evidently necessary to the community, shall they be allotted to different persons, or shall the same person execute both? This question, too, is easily answered: for in some cases the same persons may execute them, in others they should be different, where the different employments require different abilities, as when courage is wanting for one, judgment for the other, there they should be allotted to different persons; but when it is evident, that it is impossible to oblige those who have arms in their hands, and can insist on their own terms, to be always under command; there these different employments should be trusted to one person; for those who have arms in their hands have it in their option whether they will or will not assume the supreme power: to these two (namely, those who have courage and judgment) the government must be entrusted; but not in the same manner, but as nature directs; what requires courage to the young, what requires judgment to the old; for with the young is courage, with the old is wisdom: thus each will be allotted the part they are fit for according to their different merits. It is also necessary that the landed property should belong to these men; for it is necessary that the citizens should be rich, and these are the men proper for citizens; for no mechanic ought to be admitted to the rights of a citizen, nor any other sort of people whose employment is not entirely noble, honourable, and virtuous; this is evident from the principle we at first set out with; for to be happy it is necessary to be virtuous; and no one should say that a city is happy while he considers only one part of its citizens, but for that purpose he ought to examine into all of them. It is evident, therefore, that the landed property should belong to these, though it may be necessary for them to have husbandmen, either slaves, barbarians, or servants. There remains of the different classes of the people whom we have enumerated, the priests, for these evidently compose a rank by themselves; for neither are they to be reckoned amongst the husbandmen nor the mechanics; for reverence to the gods is highly becoming every state: and since the citizens have been divided into orders, the military and the council, and it is proper to offer due worship to the gods, and since it is necessary that those who are employed in their service should have nothing else to do, let the business of the priesthood be allotted to those who are in years. We have now shown what is necessary to the existence of a city, and of what parts it consists, and that husbandmen, mechanic, and mercenary servants are necessary to a city; but that the parts of it are soldiers and sailors, and that these are always different from those, but from each other only occasionally.
