If nations, as hath been observed in the preceding section, must adjust their policy on the prospect of war from abroad, they are equally bound to provide for the attainment of peace at home. But there is no peace in the absence of justice. It may subsist with divisions, disputes, and contrary opinions; but not with the commission of wrongs. The injurious, and the injured, are, as implied in the very meaning of the terms, in a state of hostility.

Where men enjoy peace, they owe it either to their mutual regards and affections, or to the restraints of law. Those are the happiest states which procure peace to their members by the first of these methods: but it is sufficiently uncommon to procure it even by the second. The first would withhold the occasions of war and of competition; the second adjusts the pretensions of men by stipulations and treaties. Sparta taught her citizens not to regard interest: other free nations secure the interest of their members, and consider this as a principal part of their rights.

Law is the treaty to which members of the same community have agreed, and under which the magistrate and the subject continue to enjoy their rights, and to maintain the peace of society. The desire of lucre is the great motive to injuries: law therefore has a principal reference to property. It would ascertain the different methods by which property may be acquired, as by prescription, conveyance, and succession; and it makes the necessary provisions for rendering the possession of property secure.

Beside avarice, there are other motives from which men are unjust; such as pride, malice, envy, and revenge. The law would eradicate the principles themselves, or at least prevent their effects.

From whatever motive wrongs are committed, there are different particulars in which the injured may suffer. He may suffer in his goods, in his person, or in the freedom of his conduct. Nature has made him master of every action which is not injurious to others. The laws of his particular society entitle him perhaps to a determinate station, and bestow on, him a certain share in the government of his country. An injury, therefore, which in this respect puts him under any unjust restraint, may be called an infringement of his political rights.
