to each other, and for the advantage of their affairs. This double law, founded on certain and invariable principles, is susceptible of demonstration, and will constitute the principal subject of this work.
There is another kind of law of nations, which authors call arbitrary, because it proceeds from the will or consent of nations. States, as well as individuals, may acquire rights and contract obligations, by express engagements, by compacts and treaties: hence results a conventional law of nations, peculiar to the contracting powers. Nations may also bind themselves by their tacit consent: upon this ground rest all those regulations which custom has introduced between different states, and which constitute the usage of nations, or the law of nations founded on custom. It is evident that this law cannot impose any obligation except on those particular nations who have, by long use, given their sanction to its maxims: it is a peculiar law, and limited in its operation, as the conventional law: both the one and the other derive all their obligatory force from that maxim of the natural law which makes it the duty of nations to fulfil their engagements, whether express or tacit. The same maxim ought to regulate the conduct of states with regard to the treaties they conclude, and the customs they adopt. I must content myself with simply laying down the general rules and principles which the law of nature furnishes for the direction of sovereigns in this respect. A particular detail of the various treaties and customs of different states belongs to history, and not to a systematic treatise on the law of nations.
Such a treatise ought, as we have already observed, principally to consist in a judicious and rational application of the principles of the law of nature to the affairs and conduct of nations and sovereigns. The study of the law of nations supposes therefore a pre-<xviii>vious knowledge of the ordinary law of nature: and in fact I proceed on the supposition that my readers are already, to a certain degree at least, possessed of that knowledge. Nevertheless, as it is not agreeable to readers in general to be obliged to recur to other authorities for proofs of what an author advances, I have taken care to establish, in a few words, the most important of those principles of the law of nature which I intended to apply to nations. But I have not always thought it necessary to trace them to their primary foundations for the purpose of demonstration, but have sometimes contented myself with supporting them by common truths which are acknowledged by every candid reader, without carrying the analysis any farther. It is sufficient for me to persuade, and for this purpose to advance nothing as a principle, that will not readily be admitted by every sensible man.
The law of nations is the law of sovereigns. It is principally for them and for their ministers that it ought to be written. All mankind are indeed interested in it; and, in a free country, the study of its maxims is a proper employment for every citizen: but it would be of little consequence to impart the knowledge of it only to private individuals, who are not called to the councils of nations, and who have no influence in directing the public measures. If the conductors of states, if all those who are employed in public affairs, condescended to apply seriously to the study of a science which ought to be their law, and, as it were, the compass by which to steer their course, what happy effects might we not expect from a good treatise on the law of nations! We every day feel the advantages of a good body of laws in civil society:—the law of nations is, in point of importance, as much superior to the civil law, as the proceedings of nations and sovereigns are more momentous in their consequences than those of private persons.
But fatal experience too plainly proves, how little regard those who are at the head of affairs pay to the <xix> dictates of justice, in conjunctures where they hope to find their advantage. Satisfied with bestowing their attention on a system of politics which is often false since often unjust, the generality of them think they have done enough when they have thoroughly studied that. Nevertheless we may truly apply to states a maxim which has long been acknowledged as true with respect to individuals,—that the best and safest policy is that which is founded on virtue. Cicero, as great a master in the art of government as in eloquence and philosophy, does not content himself with rejecting the vulgar maxim, that “a state cannot be happily governed without committing injustice”; he even proceeds so far as to lay down the very reverse of the proposition as an invariable truth, and maintains, that, “without a strict attention to the most rigid justice, public affairs cannot be advantageously administered.”*
Providence occasionally bestows on the world kings and ministers whose minds are impressed with this great truth. Let us not renounce the pleasing hope that the number of those wise conductors of nations will one day be multiplied; and in the interim let us, each in his own sphere, exert our best efforts to accelerate the happy period.
It is principally with a view of rendering my work palatable to those by whom it is of the most importance that it should be read and relished, that I have sometimes joined examples to the maxims I advance: and in that idea I have been confirmed by the approbation of one of those ministers who are the enlightened friends of the human race, and who alone ought to be admitted into the councils of kings.2 But I have been sparing in the use of such embellishments. Without ever aiming at a vain parade of erudition, I only sought to afford an occasional relaxation to the reader’s mind, <xx> or to render the doctrine more impressive by an example, and sometimes to shew that the practice of nations is conformable to the principles laid down: and whenever I found a convenient opportunity, I have, above all things, endeavoured to inspire a love of virtue, by shewing, from some striking passage of history, how amiable it is, how worthy of our homage in some truly great men, and even productive of solid advantage. I have quoted the chief part of my examples from modern history, as well because these are more interesting, as to avoid a repetition of those which have been already accumulated by Grotius, Puffendorf, and their commentators.
As to the rest, I have, both in these examples and in my reasonings, studiously endeavoured to avoid giving offence; it being my intention religiously to observe the respect due to nations and sovereign powers: but I have made it a still more sacred rule to respect the truth, and the interests of the human race. If, among the base flatterers of despotic power, my principles meet with opponents, I shall have on my side the virtuous man, the friend of the laws, the man of probity, and the true citizen.
I should prefer the alternative of total silence, were I not at liberty in my writings to obey the dictates of my conscience. But my pen lies under no restraint, and I am incapable of prostituting it to flattery. I was born in a country of which liberty is the soul, the treasure, and the fundamental law; and my birth qualifies me to be the friend of all nations. These favourable circumstances have encouraged me in the attempt to render myself useful to mankind by this work. I felt conscious of my deficiency in knowledge and abilities: I saw that I was undertaking an arduous task: but I shall rest satisfied if that class of readers whose opinions are entitled to respect, discover in my labours the traces of the honest man and the good citizen. <xxi>
