1. Having hitherto set forth how a body politic is made, and how it may be destroyed, this place requireth to say something concerning the preservation of the same. Not purposing to enter into the particulars of the art of government, but to sum up the general heads, wherein such art is to be employed, and in which consisteth the duty of him or them that have the sovereign power.
For the duty of a sovereign consisteth in the good government of the people; and although the acts of sovereign power be no injuries to the subjects who have consented to the same by their implicit wills, yet when they tend to the hurt of the people in general, they be breaches of the law of nature, and of the divine Law; and consequently, the contrary acts are the duties of sovereigns, and required at their hands to the utmost of their endeavour, by God Almighty, under the pain of eternal death. And as the art and duty of sovereigns consist in the same acts, so also doth their profit. For the end of art is profit; and governing to the profit of the subjects, is governing to the profit of the sovereign, as hath been showed Part II. chapter XXIV, section 1. And these three: 1. the law over them that have sovereign power; 2. their duty; 3. their profit: are one and the same thing contained in this sentence, Salus populi suprema lex; by which must be understood, not the mere preservation of their lives, but generally their benefit and good. So that this is the general law for sovereigns: that they procure, to the uttermost of their endeavour, the good of the people.
2. And forasmuch as eternal is better than temporal good, it is evident, that they who are in sovereign authority, are by the law of nature obliged to further the establishing of all such doctrines and rules, and the commanding of all such actions, as in their conscience they believe to be the true way thereunto.
For unless they do so, it cannot be said truly, that they have done the uttermost of their endeavour.
3. For the temporal good of people, it consisteth in four points: 1. Multitude. 2. Commodity of living. 3. Peace amongst ourselves. 4. Defence against foreign power. Concerning multitude, it is the duty of them that are in sovereign authority, to increase the people, in as much as they are governors of mankind under God Almighty, who having created but one man, and one woman, declared that it was his will they should be multiplied and increased afterwards. And seeing this is to be done by ordinances concerning copulation: they are by the law of nature bound to make such ordinances concerning the same, as may tend to the increase of mankind. And hence it cometh, that in them who have sovereign authority: not to forbid such copulations as are against the use of nature; not to forbid the promiscuous use of women; not to forbid one woman to have many husbands; not to forbid marriages within certain degrees of kindred and affinity: are against the Law of nature. For though it be not evident, that a private man living under the law of natural reason only, doth break the same, by doing any of these things aforesaid; yet it is manifestly apparent, that being so prejudicial as they are to the improvement of mankind, that not to forbid the same, is against the law of natural reason, in him that hath taken into his hands any portion of mankind to improve.
4. The commodity of living consisteth in liberty and wealth.
By Liberty I mean, that there be no prohibition without necessity of any thing to any man, which was lawful to him in the law of nature; that is to say, that there be no restraint of natural liberty, but what is necessary for the good of the commonwealth; and that well-meaning men may not fall into the danger of laws, as into snares, before they be aware. It appertaineth also to this liberty, that a man may have commodious passage from place to place, and not be imprisoned or confined with the difficulty of ways, and want of means for transportation of things necessary. And for the wealth of people, it consisteth in three things: the well ordering of trade, procuring of labour, and forbidding the superfluous consuming of food and apparel. All those therefore that are in sovereign authority, and have taken upon them the government of people, are bound by the law of nature to make ordinances consisting in the points aforenamed; as being contrary to the law of nature, unnecessarily, either for one's own fancy, to enthral, or tie men so, as they cannot move without danger; or to suffer them whose maintenance is our benefit, to want anything necessary for them, by our negligence.
