XIII. But if it be the duty of Princes to restrain the factious, much more does it concern them to dissolve and dissipate the factions themselves. Now I call a faction, a multitude of subjects gathered together, either by mutuall contracts among themselves, or by the power of some one, without his or their authority who bear the supreme Rule: A faction therefore is as it were a City in a City; for as by an Union of men in the state of nature a City receives its being, so by a new union of subjects, there ariseth a faction. According to this definition, a multitude of subjects who have bound themselves simply to obey any forreign Prince, or Subject, or have made any Pacts, or Leagues of mutuall defence between themselves against all men, not excepting those who have the supreme power in the City, is a faction. Also favour with the vulgar if it be so great, that by it an Army may be rais'd, except publique caution be given, either by hostages, or some other pledges, contains faction in it; The same may be said of private wealth, if it exceed, because all things obey mony. Forasmuch therefore as it is true, that the state of Cities among themselves is naturall, and hostile, those Princes who permit factions, doe as much as if they received an enemy within their walls, which is Contrary to the subjects safety, and therefore also against the Law of nature.
XIV. There are two things necessary to the enriching of Subjects, Labour and thrift; there is also a third which helps, to wit the naturall increase of the earth and water; and there is a fourth too, namely the Militia, which sometimes augments, but more frequently lessens the subjects stock. The two first are only necessary. For a City constituted in an Island of the Sea, no greater then will serve for dwelling, may grow rich without sowing, or fishing, by merchandize, and handicrafts only; but there is no doubt if they have a territory, but they may be richer with the same number, or equally rich, being a greater number. But the fourth, namely the Militia, was of old reckoned in the number of the gaining Arts, under the notion of Booting or taking Prey; and it was by mankind, (disperst by families) before the constitution of civill societies, accounted just and honourable; for preying, is nothing else but a warre waged with small forces; And great Common-weales, namely that of Rome, and Athens, by the spoyles of warre, forraigne tribute, and the territories they have purchased by their armes, have sometimes so improved the Common-wealth, that they have not onely not required any publique monies from the poorer sort of subjects, but have also divided to each of them both monies and lands. But this kind of increase of riches, is not to be brought into rule and fashion: For the Militia in order to profit, is like a Dye wherewith many lose their estates, but few improve them. Since therefore there are three things only, the fruits of the earth and water, Labour and Thrift, which are expedient for the enriching of subjects, the duty of Commanders in chief, shall be conversant onely about those three. For the first, those lawes will be usefull which countenance the arts that improve the increase of the earth, and water, such as are husbandry, and fishing. For the second, all Lawes against idlenesse, and such as quicken industry, are profitable; the art of Navigation (by help whereof the commodities of the whole world, bought almost by labour only, are brought into one City) and the Mechanicks, (under which I comprehend all the arts of the most excellent workmen) and the Mathematicall sciences, the fountains of navigatory and mechanick employments, are held in due esteem and honour. For the third, those lawes are usefull, whereby all inordinate expence, as well in meats, as in clothes, and universally in all things which are consumed with usage, is forbidden. Now because such lawes are beneficiall to the ends above specified, it belongs also to the Office of supreme Magistrates, to establish them.
