The Rights of War and Peace

by Hugo Grotius

XLI., XLII., XLIII. But certain precautions are necessary to prevent us from being carried away by an opinion that civil customs, though founded upon just reasons, and received among many nations, are to be reckoned as a part of the law of nature. And in the next place, it is necessary to guard against enumerating as prohibitions of natural law, things which are not proved to be so, as certain kinds of marriages the taking of interest for the use of money, and other positive injunctions of the divine, or Mosaic law. The third rule is, to make an accurate distinction between general principles, such as the duty of living according to the dictates of reason, and those of a more particular though not less obvious meaning; as the duty of forbearing to take what belongs to another. To which many truths may be added though not quite so easy of apprehension: among which may be named the cruelty of that kind of punishment, which consists in revenge, delighting in the pain of another. This is a method of proof similar to that which occurs in mathematics, the process of which rises from self-evident truths to demonstrations, the latter of which, though not intelligible to all alike, upon due examination obtain assent.

As then in matters of civil law, ignorance is deemed an excuse, so with respect to the law of nature, wherever infirmity of understanding forms an invincible obstruction to the knowledge of its rules, such infirmity may be alleged as a vindication. For as, in cases of unavoidable ignorance a great degree of the guilt of sin is removed; so it is in some measure softened wherever this ignorance subsists, though it may be owing to former negligence. And for this reason, Aristotle compares barbarians, in their rude, unformed state, to persons, whose appetites are rendered sickly by disease. Plutarch also observes that there are certain infirmities and disorders, which naturally infect the soul. Once for all, by way of conclusion we may add that wars undertaken to inflict punishment may be suspected of injustice, except there be manifest and enormous aggressions, with other conspiring causes, to vindicate nations for having recourse to arms.

XLIV. The progress of the work has necessarily led to the consideration of offences against God; the propriety or impropriety of punishing which by force of arms is a fit subject of inquiry.

Admitting the affirmative part of the question, we may observe that as in ecclesiastical affairs Bishops are intrusted with a Catholic, or general power; so kings, besides the care of their own immediate states and subjects, may be regarded as protectors of the human race. The best argument, on the negative side of the question, against the justice of such wars, is the sufficiency of the divine omnipotence to avenge its own wrongs. Yet the same may be said of other offences. For the Deity possesses sufficient power to punish them, although he leaves them to the sentence of human tribunals. Some will urge and maintain that other kinds of offences are punished only in cases, where others are uninjured or endangered by the commission of them. On the other hand, it may be said that men punish not only offences, which directly hurt others, but even those, which affect them indirectly, as suicide and other similar crimes.

Although religion is a concern between the soul of man and his Maker alone, its influence on human morals is of no inconsiderable importance. So that Plato had reason to call it the bulwark of authority and law, and the bond of every thing venerable in social order and discipline. Every false opinion in divine things, says Plutarch, is pernicious, betraying itself in the disorders of the imagination, wherever it takes root, and springs up into action. So that Aristotle reckons the care and support of religion the first of public concerns. This is a truth applying not to any particular state, but to all governments, and to human society in every shape. An avowal which Xenophon makes the characteristic of a great and wise prince, attributing to Cyrus a declaration of his firm persuasion that the more his subjects feared God, the more obedient he should find them to his laws, and the more attached to his person. But once remove the motives of religion, says Tully, and you destroy faith, the intercourse between man and man, and justice the most excellent of all virtues.

The opinions of Epicurus afford a sufficient proof of this: for in banishing the providence of God from his system, he made justice nothing but an empty name, springing from human conventions, founded on self-interest, and restraining men from the commission of crimes by no other principle but that of fear.

But there is a wider sphere, than the internal welfare of independent states, on which religion operates. In the separate society, which every kingdom, state, or country forms within itself, the place of religion may occasionally be supplied by the influence and execution of municipal laws. But in all the transactions of the great community at large, where civil laws are silent, and tribunals give way to the decision of the sword, the law of nature and of nations, founded upon the fear of God, and obedience to his will, is the standard of right to which Kings and Sovereign states appeal; a violation of which is regarded as a violation of the divine law.

XLV. But to take a closer view of the subject, we must observe that true religion, which is the same at all periods of time, rests upon four evident and universally acknowledged truths. The first of which is the being and unity of God,—the second, that God is not any of the things, that can be seen, but of a nature too sublime to be the object of human conception, or of human sight,—the third is, that with the eye of his providence he regards the events of this world, and regulates them with the most equitable and unerring judgments,—the fourth is, that he is the creator of all things, except himself. And these four truths are unfolded and laid down in an equal number of commandments, the first of which plainly declares the unity of God—the second forbids any representation, by painting or image, to be made of that being, who is invisible to mortal eye. Tacitus bears testimony to the spiritual nature of the Jewish religion: for he says, that "the Jews have nothing but a mental conception of one God, and they look upon every attempt to represent him under the appearance of human form, as a profanation of his heavenly nature."—From the third commandment we deduce his knowledge of all human transactions, even of our very thoughts; an omniscience upon which the obligation and sanctity of oaths is founded. For God is a witness even of the secret designs of the heart, so that every solemn oath is an appeal to his justice and his power, for the vindication of truth, and the punishment of falsehood.—The fourth commandment presents us with an account of the creation of the world, to commemorate which God appointed the sabbath, commanding it to be observed with a degree of reverence above every other sacred institution. For the violation of any other rites, such as those respecting forbidden meats, was left to the discretionary punishment of the law: but offences against the sabbath were capital; because, considering the nature and design of its origin, such contempt implied a disbelief, that the world was created by God. Now the creation of the world by God affords a tacit proof of his goodness, wisdom, eternity and power: and the effect of this contemplative knowledge is the offering of honour, love, worship and obedience to God. So that Aristotle says that the man, who denies that God ought to be honoured, or parents loved, should be taught to renounce his error, not by reasoning, but by punishment. And, in another place, he observes that some actions are proper on certain occasions, but reverence for the majesty of God is requisite at all times, and in all places.

The truth of those contemplative opinions may undoubtedly be proved from the nature of things; the clearest of which proofs is the evidence of sense, shewing the existence of things, which naturally leads us to consider the time, when they had no being.

But as all are not able to understand these arguments and others of the same kind, it is sufficient to observe that in all ages and all countries of the world, with very few exceptions, these opinions have found a general reception with those who were too plain in their dealings, and ingenuous in their designs, to impose upon others, and with many, who had too much sagacity to be deceived themselves. But when amid such variety of laws, customs, and opinions, there is so general an agreement upon one point; that agreement may be adduced as a proof, that such a belief owes its origin to the primitive ages of the world, from whence it has been derived to us: when we consider too that it has never been clearly refuted, it is a sufficient reason to establish our faith.
