Every tribe of warlike barbarians may entertain among themselves the strongest sentiments of affection and honour, while they carry to the rest of mankind the aspect of banditti and robbers. [Footnote: D'Arvieux's History of the Arabs.] They may be indifferent to interest, and superior to danger; but our sense of humanity, our regard to the rights of nations, our admiration of civil wisdom and justice, even our effeminacy itself, make us turn away with contempt, or with horror, from a scene which exhibits so few of our good qualities, and which serves so much to reproach our weakness. It is in conducting the affairs of civil society, that mankind find the exercise of their best talents, as well as the object of their best affections. It is in being grafted on the advantages of civil society, that the art of war is brought to perfection; that the resources of armies, and the complicated springs to be touched in their conduct, are best understood. The most celebrated warriors were also citizens: opposed to a Roman, or a Greek, the chieftain of Thrace, of Germany, or Gaul, was a novice. The native of Pella learned the principles of his art from Epaminondas and Pelopidas. 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.
