him, call the internal law of nations, on account of its being obligatory on nations in point of conscience. Several writers term it the natural law of nations.
Since therefore the necessary law of nations consists in the application of the law of nature to states,—which law is immutable, as being founded on the nature of things, and particularly on the nature of man,—it follows, that the necessary law of nations is immutable.
§9. Nations can make no change in it, nor dispense with the obligations arising from it.
Whence, as this law is immutable, and the obligations that arise from it necessary and indispensable, nations can neither make any changes in it by their conventions, dispense with it in their own conduct, nor reciprocally release each other from the observance of it.
This is the principle by which we may distinguish lawful conventions or treaties from those that are not lawful, and innocent and rational customs from those that are unjust or censurable.
There are things, just in themselves, and allowed by the necessary law of nations, on which states may mutually agree with each other, and which they may consecrate and enforce by their manners and customs. There are <lix> others, of an indifferent nature, respecting which, it rests at the option of nations to make in their treaties whatever agreements they please, or to introduce whatever custom or practice they think proper. But every treaty, every custom, which contravenes the injunctions or prohibitions of the necessary law of nations, is unlawful. It will appear, however, in the sequel, that it is only by the internal law, by the law of conscience, such conventions or treaties are always condemned as unlawful,—and that, for reasons which shall be given in their proper place, they are nevertheless often valid by the external law. Nations being free and independent,—though the conduct of one of them be illegal and condemnable by the laws of conscience, the others are bound to acquiesce in it, when it does not infringe upon their perfect rights. The liberty of that nation would not remain entire, if the others were to arrogate to themselves the right of inspecting and regulating her actions;—an assumption on their part, that would be contrary to the law of nature, which declares every nation free and independent of all the others.
§10. Society established by nature between all mankind;
Man is so formed by nature, that he cannot supply all his own wants, but necessarily stands in need of the intercourse and assistance of his fellow-creatures, whether for his immediate preservation, or for the sake of perfecting his nature, and enjoying such a life as is suitable to a rational being. This is sufficiently proved by experience. We have instances of persons, who, having grown up to manhood among the bears of the forest, enjoyed not the use of speech or of reason, but were, like the brute beasts, possessed only of sensitive faculties. We see moreover that nature has refused to bestow on men the same strength and natural weapons of defence with which she has furnished other animals,—having, in lieu of those advantages, endowed mankind with the faculties of speech and reason, or at least a capability of acquiring them by an intercourse with their fellow-creatures. Speech enables them to communicate with each other, to give each other mutual assistance, to perfect their reason and knowledge; and having thus become intelligent, they find a thousand methods of preserving themselves, and supplying their wants. Each individual, moreover, is intimately conscious that he can neither live happily nor improve his nature without the intercourse and assistance of others. Since, therefore, na-<lx>ture has thus formed mankind, it is a convincing proof of her intention that they should communicate with and mutually aid and assist each other.
Hence is deduced the establishment of natural society among men. The general law of that society is, that each individual should do for the others every thing which their necessities require, and which he can perform without neglecting the duty that he owes to himself: a law which all men must observe in order to live in a manner consonant to their nature, and conformable to the views of their common creator,—a law which our own safety, our happiness, our dearest interests, ought to render sacred to every one of us. Such is the general obligation that binds us to the observance of our duties: let us fulfil them with care, if we would wisely endeavour to promote our own advantage.
It is easy to conceive what exalted felicity the world would enjoy, were all men willing to observe the rule that we have just laid down. On the contrary, if each man wholly and immediately directs all his thoughts to his own interest, if he does nothing for the sake of other men, the whole human race together will be immersed in the deepest wretchedness. Let us therefore endeavour to promote the general happiness of mankind: all mankind, in return, will endeavour to promote ours; and thus we shall establish our felicity on the most solid foundations.
The universal society of the human race being an institution of nature herself, that is to say, a necessary consequence of the nature of man,—all men, in whatever stations they are placed, are bound to cultivate it, and to discharge its duties. They cannot liberate themselves from the obligation by any convention, by any private association. When, therefore, they unite in civil society for the purpose of forming a separate state or nation, they may indeed enter into particular engagements towards those with whom they associate themselves; but they remain still bound to the performance of their duties towards the rest of mankind. All the difference consists in this, that, having agreed to act in common, and having resigned their rights and submitted their will to the body of the society, in every thing that concerns their common welfare,—it thenceforward belongs to that body, that state, and its rulers, to fulfil the duties of humanity <lxi> towards strangers, in every thing that no longer depends on the liberty of individuals; and it is the state more particularly that is to perform those duties towards other states. We have already seen (§5) that men united in society remain subject to the obligations imposed upon them by human nature. That society, considered as a moral person, since possessed of an understanding, volition, and strength peculiar to itself, is therefore obliged to live on the same terms with other societies or states, as individual man was obliged, before those establishments, to live with other men, that is to say, according to the laws of the natural society established among the human race, with the difference only of such exceptions as may arise from the different nature of the subjects.
§12. The object of this society of nations.
Since the object of the natural society established between all mankind is that they should lend each other mutual assistance in order to attain perfection themselves and to render their condition as perfect as possible,—and since nations, considered as so many free persons living together in a state of nature, are bound to cultivate human society with each other,—the object of the great society established by nature between all nations is also the interchange of mutual assistance for their own improvement and that of their condition.
§13. General obligation imposed by it.
The first general law that we discover in the very object of the society of nations, is that each individual nation is bound to contribute every thing in her power to the happiness and perfection of all the others.*
§14. Explanation of this observation.
But the duties that we owe to ourselves being unquestionably paramount to those we owe to others,—a nation owes herself in the first instance, and in preference to all other nations, to do every thing she can to promote her own happiness and perfection. (I say every thing she can, not only in a physical but in a moral sense,—that is, every thing that she can do lawfully, and consistently with justice and honour.) When therefore she cannot contribute to the welfare
