It is a settled point with writers on the natural law, that all men inherit from nature a perfect liberty and independence, of which they cannot be deprived without their own consent. In a state, the individual citizens do not enjoy them fully and absolutely, because they have made a partial surrender of them to the sovereign. But the body of the nation, the state, remains absolutely free and independent with respect to all other men, all other nations, as long as it has not voluntarily submitted to them.
§5. To what laws nations are subject.
As men are subject to the laws of nature,—and as their union in civil society cannot have exempted them from the obligation to observe those laws, since by that union they do not cease to be men,—the entire nation, whose common will is but the result of the united wills of the citizens, remains subject to the laws of nature, and is bound to respect them in all her proceedings. And since right arises from obligation, as we have just observed (§3), the nation possesses also the same rights which nature has conferred upon men in order to enable them to perform their duties.
§6. In what the law of nations originally consists.
We must therefore apply to nations the rules of the law of nature, in order to discover what their obligations are, and what their rights: consequently the law of nations is originally no other than the law of nature applied to nations. But as the application of a rule cannot be just and reasonable unless it be made in a manner suitable to the subject, we are not to imagine that the law of nations is precisely and in every case the same as the law of nature, with the difference only of the subjects to which it is applied, so as to allow of our substituting nations for individuals. A state or civil society is a subject very different from an individual of the human race: from which circumstance, pursuant to the law of nature itself, there result, in many cases, very different obligations and rights; <lvii> since the same general rule, applied to two subjects, cannot produce exactly the same decisions, when the subjects are different; and a particular rule which is perfectly just with respect to one subject, is not applicable to another subject of a quite different nature. There are many cases, therefore, in which the law of nature does not decide between state and state in the same manner as it would between man and man. We must therefore know how to accommodate the application of it to different subjects; and it is the art of thus applying it with a precision founded on right reason, that renders the law of nations a distinct science.* <lviii>
§7. Definition of the necessary law of nations.
We call that the necessary law of nations which consists in the application of the law of nature to nations. It is necessary, because nations are absolutely bound to observe it. This law contains the precepts prescribed by the law of nature to states, on whom that law is not less obligatory than on individuals, since states are composed of men, their resolutions are taken by men, and the law of nature is binding on all men, under whatever relation they act. This is the law which Grotius, and those who follow 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.
