doing an es-<lxii>sential injury to herself, her obligation ceases on that particular occasion, and she is considered as lying under disability to perform the office in question.
§15. The second general law is the liberty and independence of nations.
Nations being free and independent of each other, in the same manner as men are naturally free and independent, the second general law of their society is, that each nation should be left in the peaceable enjoyment of that liberty which she inherits from nature. The natural society of nations cannot subsist, unless the natural rights of each be duly respected. No nation is willing to renounce her liberty: she will rather break off all commerce with those states that should attempt to infringe upon it.
As a consequence of that liberty and independence, it exclusively belongs to each nation to form her own judgment of what her conscience prescribes to her,—of what she can or cannot do,—of what it is proper or improper for her to do: and of course it rests solely with her to examine and determine whether she can perform any office for another nation without neglecting the duty which she owes to herself. In all cases, therefore, in which a nation has the right of judging what her duty requires, no other nation can compel her to act in such or such particular manner: for any attempt at such compulsion would be an infringement on the liberty of nations. We have no right to use constraint against a free person except in those cases where such person is bound to perform some particular thing for us, and for some particular reason which does not depend on his judgment,—in those cases, in short, where we have a perfect right against him.
§17. Distinctions between internal and external, perfect and imperfect obligations and rights.
In order perfectly to understand this, it is necessary to observe, that the obligation, and the right which corresponds to or is derived from it, are distinguished into external and internal. The obligation is internal, as it binds the conscience, and is deduced from the rules of our duty: it is external, as it is considered relatively to other men, and produces some right between them. The internal obligation is always the same in its nature, though it varies in degree: but the external obligation is divided into perfect and imperfect; and the right that results from it is also perfect or imperfect. The perfect right is that which is accompanied by the right of compelling those who refuse to fulfil the correspondent obligation; the imperfect right is unaccompanied by that right of compulsion. The <lxiii> perfect obligation is that which gives to the opposite party the right of compulsion; the imperfect gives him only a right to ask.
It is now easy to conceive why the right is always imperfect, when the correspondent obligation depends on the judgment of the party in whose breast it exists: for if, in such a case, we had a right to compel him, he would no longer enjoy the freedom of determination respecting the conduct he is to pursue in order to obey the dictates of his own conscience. Our obligation is always imperfect with respect to other people, while we possess the liberty of judging how we are to act: and we retain that liberty on all occasions where we ought to be free.
Since men are naturally equal, and a perfect equality prevails in their rights and obligations, as equally proceeding from nature,—nations composed of men, and considered as so many free persons living together in the state of nature, are naturally equal, and inherit from nature the same obligations and rights. Power or weakness does not in this respect produce any difference. A dwarf is as much a man as a giant; a small republic is no less a sovereign state than the most powerful kingdom.
By a necessary consequence of that equality, whatever is lawful for one nation, is equally lawful for any other; and whatever is unjustifiable in the one, is equally so in the other.
A nation then is mistress of her own actions so long as they do not affect the proper and perfect rights of any other nation,—so long as she is only internally bound, and does not lie under any external and perfect obligation. If she makes an ill use of her liberty, she is guilty of a breach of duty; but other nations are bound to acquiesce in her conduct, since they have no right to dictate to her.
§21. Foundation of the voluntary law of nations.
Since nations are free, independent, and equal,—and since each possesses the right of judging, according to the dictates of her conscience, what conduct she is to pursue in order to fulfil her duties,—the effect of the whole is, to produce, at least externally and in the eyes of mankind, a perfect equality of rights between nations, in the administration of their affairs and the pursuit of their pretensions, without regard to the intrinsic justice of their conduct, of which others have no right to form a definitive judgment; so that whatever may be done by any one nation, may be <lxiv> done by any other; and they ought, in human society, to be considered as possessing equal rights.
Each nation in fact maintains that she has justice on her side in every dispute that happens to arise: and it does not belong to either of the parties interested, or to other nations, to pronounce a judgment on the contested question. The party who is in the wrong is guilty of a crime against her own conscience: but as there exists a possibility that she may perhaps have justice on her side, we cannot accuse her of violating the laws of society.
It is therefore necessary, on many occasions, that nations should suffer certain things to be done, though in their own nature unjust and condemnable; because they cannot oppose them by open force, without violating the liberty of some particular state, and destroying the foundations of their natural society. And since they are bound to cultivate that society, it is of course presumed that all nations have consented to the principle we have just established. The rules that are deduced from it, constitute what Monsieur Wolf calls “the voluntary law of nations”; and there is no reason why we should not use the same term, although we thought it necessary to deviate from that great man in our manner of establishing the foundation of that law.
§22. Right of nations against the infractors of the law of nations.
The laws of natural society are of such importance to the safety of all states, that, if the custom once prevailed of trampling them under foot, no nation could flatter herself with the hope of preserving her national existence, and enjoying domestic tranquillity, however attentive to pursue every measure dictated by the most consummate prudence, justice, and moderation.* Now all men and all states have a perfect right to those things that are necessary for their preservation, since that right corresponds to an indispensable obligation. All nations have therefore a right to resort to forcible means for the purpose of repressing any one particular nation who openly violates the laws of the society which nature has established between them, or who directly attacks the welfare and safety of that society.
But care must be taken not to extend that right to the <lxv> prejudice of the liberty of nations. They are all free and independent, but bound to observe the laws of that society which nature has established between them; and so far bound, that, when any one of them violates those laws, the others have a right to repress her. The conduct of each nation, therefore, is no farther subject
