PREFACE↩

This translation of Kant’s essay on Perpetual Peace was undertaken by Miss Mary Campbell Smith at the suggestion of the late Professor Ritchie of St. Andrews, who had promised to write for it a preface, indicating the value of Kant’s work in relation to recent discussions regarding the possibility of “making wars to cease.” In view of the general interest which these discussions have aroused and of the vague thinking and aspiration which have too often characterised them, it seemed to Professor Ritchie that a translation of this wise and sagacious essay would be both opportune and valuable.[1] His untimely death has prevented the fulfilment of his promise, and I have been asked, in his stead, to introduce the translator’s work.

This is, I think, the only complete translation into English of Kant’s essay, including all the notes as well as the text, and the translator has added a full historical Introduction, along with numerous notes of her own, so as (in Professor Ritchie’s words) “to meet the needs (1) of the student of Political [p. vi] Science who wishes to understand the relation of Kant’s theories to those of Grotius, Hobbes, Locke, Rousseau etc., and (2) of the general reader who wishes to understand the significance of Kant’s proposals in connection with the ideals of Peace Congresses, and with the development of International Law from the end of the Middle Ages to the Hague Conference.”

Although it is more than 100 years since Kant’s essay was written, its substantial value is practically unimpaired. Anyone who is acquainted with the general character of the mind of Kant will expect to find in him sound common-sense, clear recognition of the essential facts of the case and a remarkable power of analytically exhibiting the conditions on which the facts necessarily depend. These characteristics are manifest in the essay on Perpetual Peace. Kant is not pessimist enough to believe that a perpetual peace is an unrealisable dream or a consummation devoutly to be feared, nor is he optimist enough to fancy that it is an ideal which could easily be realised if men would but turn their hearts to one another. For Kant perpetual peace is an ideal, not merely as a speculative Utopian idea, with which in fancy we may play, but as a moral principle, which ought to be, and therefore can be, realised. Yet he makes it perfectly clear that we cannot hope to approach the realisation [p. vii] of it unless we honestly face political facts and get a firm grasp of the indispensable conditions of a lasting peace. To strive after the ideal in contempt or in ignorance of these conditions is a labour that must inevitably be either fruitless or destructive of its own ends. Thus Kant demonstrates the hopelessness of any attempt to secure perpetual peace between independent nations. Such nations may make treaties; but these are binding only for so long as it is not to the interest of either party to denounce them. To enforce them is impossible while the nations remain independent. “There is,” as Professor Ritchie put it (Studies in Political and Social Ethics, p. 169), “only one way in which war between independent nations can be prevented; and that is by the nations ceasing to be independent.” But this does not necessarily mean the establishment of a despotism, whether autocratic or democratic. On the other hand, Kant maintains that just as peace between individuals within a state can only be permanently secured by the institution of a “republican” (that is to say, a representative) government, so the only real guarantee of a permanent peace between nations is the establishment of a federation of free “republican” states. Such a federation he regards as practically possible. “For if Fortune ordains that a powerful and enlightened people should form a republic [p. viii] —which by its very nature is inclined to perpetual peace—this would serve as a centre of federal union for other states wishing to join, and thus secure conditions of freedom among the states in accordance with the idea of the law of nations. Gradually, through different unions of this kind, the federation would extend further and further.”

Readers who are acquainted with the general philosophy of Kant will find many traces of its influence in the essay on Perpetual Peace. Those who have no knowledge of his philosophy may find some of his forms of statement rather difficult to understand, and it may therefore not be out of place for me to indicate very briefly the meaning of some terms which he frequently uses, especially in the Supplements and Appendices. Thus at the beginning of the First Supplement, Kant draws a distinction between the mechanical and the teleological view of things, between “nature” and “Providence”, which depends upon his main philosophical position. According to Kant, pure reason has two aspects, theoretical and practical. As concerning knowledge, strictly so called, the a priori principles of reason (e.g. substance and attribute, cause and effect etc.) are valid only within the realm of possible sense-experience. Such ideas, for instance, cannot be extended to God, since He is not a possible object of sense-experience. They are limited [p. ix] to the world of phenomena. This world of phenomena (“nature” or the world of sense-experience) is a purely mechanical system. But in order to understand fully the phenomenal world, the pure theoretical reason must postulate certain ideas (the ideas of the soul, the world and God), the objects of which transcend sense-experience. These ideas are not theoretically valid, but their validity is practically established by the pure practical reason, which does not yield speculative truth, but prescribes its principles “dogmatically” in the form of imperatives to the will. The will is itself practical reason, and thus it imposes its imperatives upon itself. The fundamental imperative of the practical reason is stated by Kant in Appendix I. (p. 175):—“Act so that thou canst will that thy maxim should be a universal law, be the end of thy action what it will.” If the end of perpetual peace is a duty, it must be necessarily deduced from this general law. And Kant does regard it as a duty. “We must desire perpetual peace not only as a material good, but also as a state of things resulting from our recognition of the precepts of duty” (loc. cit.). This is further expressed in the maxim (p. 177):—“Seek ye first the kingdom of pure practical reason and its righteousness, and the object of your endeavour, the blessing of perpetual peace, will be added unto you.” The distinction between the [p. x] moral politician and the political moralist, which is developed in Appendix I., is an application of the general distinction between duty and expediency, which is a prominent feature of the Kantian ethics. Methods of expediency, omitting all reference to the pure practical reason, can only bring about re-arrangements of circumstances in the mechanical course of nature. They can never guarantee the attainment of their end: they can never make it more than a speculative ideal, which may or may not be practicable. But if the end can be shown to be a duty, we have, from Kant’s point of view, the only reasonable ground for a conviction that it is realisable. We cannot, indeed, theoretically know that it is realisable. “Reason is not sufficiently enlightened to survey the series of predetermining causes which would make it possible for us to predict with certainty the good or bad results of human action, as they follow from the mechanical laws of nature; although we may hope that things will turn out as we should desire” (p. 163). On the other hand, since the idea of perpetual peace is a moral ideal, an “idea of duty”, we are entitled to believe that it is practicable. “Nature guarantees the coming of perpetual peace, through the natural course of human propensities; not indeed with sufficient certainty to enable us to prophesy the future of this ideal theoretically, but yet clearly [p. xi] enough for practical purposes” (p. 157). One might extend this discussion indefinitely; but what has been said may suffice for general guidance.

The “wise and sagacious” thought of Kant is not expressed in a simple style, and the translation has consequently been a very difficult piece of work. But the translator has shown great skill in manipulating the involutions, parentheses and prodigious sentences of the original. In this she has had the valuable help of Mr. David Morrison, M.A., who revised the whole translation with the greatest care and to whom she owes the solution of a number of difficulties. Her work will have its fitting reward if it succeeds in familiarising the English-speaking student of politics with a political essay of enduring value, written by one of the master thinkers of modern times.

TRANSLATOR’S INTRODUCTION↩

This is an age of unions. Not merely in the economic sphere, in the working world of unworthy ends and few ideals do we find great practical organizations; but law, medicine, science, art, trade, commerce, politics and political economy—we might add philanthropy—standing institutions, mighty forces in our social and intellectual life, all have helped to swell the number of our nineteenth century Conferences and Congresses. It is an age of Peace Movements and Peace Societies, of peace-loving monarchs and peace-seeking diplomats. This is not to say that we are preparing for the millennium. Men are working together, there is a newborn solidarity of interest, but rivalries between nation and nation, the bitternesses and hatreds inseparable from competition are not less keen; prejudice and misunderstanding not less frequent; subordinate conflicting interests are not fewer, are perhaps, in view of changing political conditions and an ever-growing international commerce, multiplying with every year. The talisman is, perhaps, self-interest, but, none the less, the spirit of union is there; it is impossible to ignore a clearly marked [p. 2] tendency towards international federation, towards political peace. This slow movement was not born with Peace Societies; its consummation lies perhaps far off in the ages to come. History at best moves slowly. But something of its past progress we shall do well to know. No political idea seems to have so great a future before it as this idea of a federation of the world. It is bound to realise itself some day; let us consider what are the chances that this day come quickly, what that it be long delayed. What obstacles lie in the way, and how may they be removed? What historical grounds have we for hoping that they may ever be removed? What, in a word, is the origin and history of the idea of a perpetual peace between nations, and what would be the advantage, what is the prospect of realising it?

The international relations of states find their expression, we are told, in war and peace. What has been the part played by these great counteracting forces in the history of nations? What has it been in prehistoric times, in the life of man in what is called the “state of nature”? “It is no easy enterprise,” says Rousseau, in more than usually careful language, “to disentangle that which is original from that which is artificial in the actual state of man, and to make ourselves well acquainted with a state which no longer exists, which perhaps [p. 3] never has existed and which probably never will exist in the future.” (Preface to the Discourse on the Causes of Inequality, 1753, publ. 1754.) This is a difficulty which Rousseau surmounts only too easily. A knowledge of history, a scientific spirit may fail him: an imagination ever ready to pour forth detail never does. Man lived, says he, “without industry, without speech, without habitation, without war, without connection of any kind, without any need of his fellows or without any desire to harm them ... sufficing to himself.”[2] (Discourse on the Sciences and Arts, 1750.) Nothing, we are now certain, is less probable. We cannot paint the life of man at this stage of his development with any definiteness, but the conclusion is forced upon us that our race had no golden age,[3] no peaceful beginning, that this early state was indeed, as [p. 4] Hobbes held, a state of war, of incessant war between individuals, families and, finally, tribes.

The Early Conditions of Society.

For the barbarian, war is the rule; peace the exception. His gods, like those of Greece, are warlike gods; his spirit, at death, flees to some Valhalla. For him life is one long battle; his arms go with him even to the grave. Food and the means of existence he seeks through plunder and violence. Here right is with might; the battle is to the strong. Nature has given all an equal claim to all things, but not everyone can have them. This state of fearful insecurity is bound to come to an end. “Government,” says Locke, (On Civil Government, Chap. VIII., § 105) “is hardly to be [p. 5] avoided amongst men that live together.”[4] A constant dread of attack and a growing consciousness of the necessity of presenting a united front against it result in the choice of some leader—the head of a family perhaps—who acts, it may be, only as captain of the hosts, as did Joshua in Israel, or who may discharge the simple duties of a primitive governor or king.[5] Peace within is found to be strength without. The civil state is established, so that “if there needs must be war, it may not yet [p. 6] be against all men, nor yet without some helps.” (Hobbes: On Liberty, Chap. I., § 13.) This foundation of the state is the first establishment in history of a peace institution. It changes the character of warfare, it gives it method and system; but it does not bring peace in its train. We have now, indeed, no longer a wholesale war of all against all, a constant irregular raid and plunder of one individual by another; but we have the systematic, deliberate war of community against community, of nation against nation.[6]

War in Classical Times.

In early times, there were no friendly neighbouring nations: beyond the boundaries of every [p. 7] nation’s territory, lay the land of a deadly foe. This was the way of thinking, even of so highly cultured a people as the Greeks, who believed that a law of nature had made every outsider, every barbarian their inferior and their enemy.[7] Their treaties of peace, at the time of the Persian War, were frankly of the kind denounced by Kant, mere armistices concluded for the purpose of renewing their fighting strength. The ancient world is a world of perpetual war in which defeat meant annihilation. In the East no right was recognised in the enemy; and even in Greece and Rome the fate of the unarmed was death or slavery.[8] The [p. 8] barbaric or non-Grecian states had, according to Plato and Aristotle, no claim upon humanity, no [p. 9] rights in fact of any kind. Among the Romans things were little better. According to Mr. T. J. Lawrence—see his Principles of International Law, III., §§ 21, 22—they were worse. For Rome stood alone in the world: she was bound by ties of kinship to no other state. She was, in other words, free from a sense of obligation to other races. War, according to Roman ideas, was made by the gods, apart altogether from the quarrels of rulers or races. To disobey the sacred command, expressed in signs and auguries would have been to hold in disrespect the law and religion of the land. When, in the hour of victory, the Romans refrained from pressing their rights against the conquered—rights recognised by all Roman jurists—it was from no spirit of leniency, but in the pursuit of a prudent and far-sighted policy, aiming at the growth of Roman supremacy and the establishment of a world-embracing empire, shutting out all war as it blotted out natural boundaries, reducing all rights to the one right of imperial citizenship. There was no real jus belli, even here in the cradle of international law; the only limits to the fury of war were of a religious character.

The treatment of a defeated enemy among the Jews rested upon a similar religious foundation. In the East, we find a special cruelty in the conduct of war. The wars of the Jews and Assyrians were [p. 10] wars of extermination. The whole of the Old Testament, it has been said, resounds with the clash of arms.[9] “An eye for an eye, a tooth for a tooth!” was the command of Jehovah to his chosen people. Vengeance was bound up in their very idea of the Creator. The Jews, unlike the followers of Mahomet, attempted, and were commanded to attempt no violent conversion[10]; they were then too weak a nation; but they fought, and fought with success against the heathen of neighbouring lands, the Lord of Hosts leading them forth to battle. The God of Israel stood to his chosen people in a unique and peculiarly logical relation. He had made a covenant with them; and, in return for their obedience and allegiance, cared for their interests and advanced their national prosperity. The blood of this elect people could not be suffered to intermix with that of idolaters. Canaan must be cleared of the heathen, on the coming [p. 11] of the children of Israel to their promised land; and mercy to the conquered enemy, even to women, children or animals was held by the Hebrew prophets to be treachery to Jehovah. (Sam. XV.; Josh. VI. 21.)

Hence the attitude of the Jews to neighbouring nations[11] was still more hostile than that of the Greeks. The cause of this difference is bound up with the transition from polytheism to monotheism. The most devout worshipper of the national gods of ancient times could endure to see other gods than his worshipped in the next town or by a neighbouring nation. There was no reason why all should not exist side by side. Religious conflicts in polytheistic countries, when they arose, were due not to the rivalry of conflicting faiths, but to an occasional attempt to put one god above the others in importance. There could be no interest here in the propagation of belief through the sword. But, under the Jews, these relations were entirely altered. Jehovah, their Creator, became the one invisible God. Such an one can suffer no others near him; their existence is a continual insult to him. Monotheism is, in its very nature, a religion of intolerance. Its spirit among the Jews was warlike: it commanded [p. 12] the subjugation of other nations, but its instrument was rather extermination than conversion.

The Attitude of Christianity and the Early Church to War.

From the standpoint of the peace of nations, we may say that the Christian faith, compared with other prominent monotheistic religious systems, occupies an intermediate position between two extremes—the fanaticism of Islam, and to a less extent of Judaism, and the relatively passive attitude of the Buddhist who thought himself bound to propagate his religion, but held himself justified only in the employment of peaceful means. Christianity, on the other hand, contains no warlike principles: it can in no sense be called a religion of the sword, but circumstances gave the history of the Church, after the first few centuries of its existence, a character which cannot be called peace-loving.

This apparent contradiction between the spirit of the new religion and its practical attitude to war has led to some difference of opinion as to the actual teaching of Christ. The New Testament seems, at a superficial glance, to furnish support as readily to the champions of war as to its denouncers. The Messiah is the Prince of Peace (Is. IX. 6, 7; Heb. VI.), and here lies the way of [p. 13] righteousness (Rom. III. 19): but Christ came not to bring peace, but a sword (Matth. X. 34). Such statements may be given the meaning which we wish them to bear—the quoting of Scripture is ever an unsatisfactory form of evidence; but there is no direct statement in the New Testament in favour of war, no saying of Christ which, fairly interpreted, could be understood too regard this proof of human imperfection as less condemnable than any other.[12] When men shall be without sin, nation shall rise up against nation no more. But man the individual can attain peace only when he has overcome the world, when, in the struggle with his lower self, he has come forth victorious. This is the spiritual sword which Christ brought into the world—strife, not with the unbeliever, but with the lower self: meekness and the spirit of the Word of God are the weapons with which man must fight for the Faith.

An elect people there was no longer: Israel had rejected its Messiah. Instead there was a complete brotherhood of all men, the bond and the free, as children of one God. The aim of the Church was a world-empire, bound together by a universal religion. In this sense, as sowing the first seeds of a universal peace, we may speak [p. 14] of Christianity as a re-establishment of peace among mankind.

The later attitude of Christians to war, however, by no means corresponds to the earliest tenets of the Church. Without doubt, certain sects, from the beginning of our era and through the ages up to the present time, held, like the Mennonites and Quakers in our day, that the divine command, “Love your enemies,” could not be reconciled with the profession of a soldier. The early Christians were reproached under the Roman Emperors, before the time of Constantine, with avoiding the citizen’s duty of military service.[13] “To those enemies of our faith,” wrote Origen (Contra Celsum, VIII., Ch. LXXIII., Anti-Nicene Christian Library), “who require us to bear arms for the commonwealth, and to slay men, we can reply: ‘Do not those who are priests at certain shrines, and those who attend on certain gods, as you account them, keep their hands free from blood, that they may with hands unstained and free from human blood offer the appointed sacrifices to your [p. 15] gods; and even when war is upon you, you never enlist the priests in the army. If that, then, is a laudable custom, how much more so, that while others are engaged in battle, these too should engage as the priests and ministers of God, keeping their hands pure, and wrestling in prayers to God on behalf of those who are fighting in a righteous cause, and for the king who reigns righteously, that whatever is opposed to those who act righteously may be destroyed!’ ... And we do take our part in public affairs, when along with righteous prayers we join self-denying exercises and meditations, which teach us to despise pleasures, and not to be led away by them. And none fight better for the king than we do. We do not indeed fight under him, although he require it; but we fight on his behalf, forming a special army—an army of piety—by offering our prayers to God.” The Fathers of the Church, Justin Martyr, Clement of Alexandria, Tertullian, Ambrose and the rest gave the same testimony against war. The pagan rites connected with the taking of the military oath had no doubt some influence in determining the feeling of the pious with regard to this life of bloodshed; but the reasons lay deeper. “Shall it be held lawful,” asked Tertullian, (De Corona, p. 347) “to make an occupation of the sword, when the Lord proclaims that he who uses the sword shall perish [p. 16] by the sword? And shall the son of peace take part in the battle when it does not become him even to sue at law? And shall he apply the chain, and the prison, and the torture, and the punishment, who is not the avenger even of his own wrongs?”

The doctrine of the Church developed early in the opposite direction. It was its fighting spirit and not a love of peace that made Christianity a state religion under Constantine. Nor was Augustine the first of the Church Fathers to regard military service as permissible. To come to a later time, this change of attitude has been ascribed partly to the rise of Mahometan power and the wave of fanaticism which broke over Europe. To destroy these unbelievers with fire and sword was regarded as a deed of piety pleasing to God. Hence the wars of the Crusades against the infidel were holy wars, and appear as a new element in the history of civilisation. The nations of ancient times had known only civil and foreign war.[14] They had rebelled at home, and they had fought mainly for material interests abroad. In the Middle Ages there were, besides, religious wars and, with the rise of [p. 17] Feudalism, private war:[15] among all the powers of the Dark Ages and for centuries later, none was more aggressive than the Catholic Church, nor a more active and untiring defender of its rights and claims, spiritual or temporal. It was in some respects a more warlike institution than the states of Greece and Rome. It struggled through centuries with the Emperor:[16] it pronounced its ban against disobedient states and disloyal cities: it pursued with its vengeance each heretical or rebellious prince: unmindful of its early traditions about peace, it showed in every crisis a fiercely military spirit.[17]

For more than a thousand years the Church [p. 18] counted fighting clergy[18] among its most active supporters. This strange anomaly was, it must be said, at first rather suffered in deference to public opinion than encouraged by ecclesiastical canons and councils, but it gave rise to great discontent at the time of the Reformation.[19] The whole question of the lawfulness of military service for Christians was then raised again. “If there be anything in the affairs of mortals,” wrote Erasmus at this time (Opera, II., Prov., 951 C) “which it [p. 19] becomes us deliberately to attack, which we ought indeed to shun by every possible means, to avert and to abolish, it is certainly war, than which there is nothing more wicked, more mischievous or more widely destructive in its effects, nothing harder to be rid of, or more horrible and, in a word, more unworthy of a man, not to say of a Christian.”[20] The mediæval Church indeed succeeded, by the establishment of such institutions as the Truce of God, in setting some limits to the fury of the soldier: but its endeavours (and it made several to promote peace)[21] were only to a trifling extent successful. Perhaps custom and public opinion in feudal Europe were too strong, perhaps the Church showed a certain apathy in denouncing the evils of a military society: no doubt the theoretical tenets of its doctrine did less to hinder war than its own strongly military tendency, its [p. 20] lust for power and the force of its example did to encourage it.

Hence, in spite of Christianity and its early vision of a brotherhood of men, the history of the Middle Ages came nearer to a realization of the idea of perpetual war than was possible in ancient times. The tendency of the growth of Roman supremacy was to diminish the number of wars, along with the number of possible causes of racial friction. It united many nations in one great whole, and gave them, to a certain extent, a common culture and common interests; even, when this seemed prudent, a common right of citizenship. The fewer the number of boundaries, the less the likelihood of war. The establishment of great empires is of necessity a force, and a great and permanent force working on the side of peace. With the fall of Rome this guarantee was removed.

The Development of the New Science of International Law.

Out of the ruins of the old feudal system arose the modern state as a free independent unity. Private war between individuals or classes of society was now branded as a breach of the peace: it became the exclusive right of kings to appeal to [p. 21] force. War, wrote Gentilis[22] towards the end of sixteenth century, is the just or unjust conflict between states. Peace was now regarded as the normal condition of society. As a result of these great developments in which the name “state” acquired new meaning, jurisprudence freed itself from the trammelling conditions of mediæval Scholasticism. Men began to consider the problem of the rightfulness or wrongfulness of war, to question even the possibility of a war on rightful grounds. Out of theses new ideas—partly too as one of the fruits of the Reformation,[23]—arose the first consciously formulated principles of the science of international law, whose fuller, but not yet complete, development belongs to modern times.

From the beginning of history every age, every [p. 22] people has something to show here, be it only a rudimentary sense of justice in their dealings with one another. We may instance the Amphictyonic League in Greece which, while it had a merely Hellenic basis and was mainly a religious survival, shows the germ of some attempt at arbitration between Greek states. Among the Romans we have the jus feciale[24] and the jus gentium, as distinguished from the civil law of Rome, and certain military regulations about the taking of booty in war. Ambassadors were held inviolate [p. 23] in both countries; the formal declaration of war was never omitted. Many Roman writers held the necessity of a just cause for war. But nowhere do these considerations form the subject matter of a special science.

In the Middle Ages the development of these ideas received little encouragement. All laws are silent in the time of war,[25] and this was a period of war, both bloody and constant. There was no time to think of the right or wrong of anything. Moreover, the Church emphasised the lack of rights in unbelievers, and gave her blessing on their annihilation.[26] The whole Christian world was filled with the idea of a spiritual universal monarchy. Not such as that in the minds of Greek and Jew and Roman who had been able to picture international peace only under the form of a great national and exclusive empire. In this great Christian state there were to be no distinctions between nations; its sphere was bounded by the universe. But, here, there was no room or recognition for independent national states with equal and personal rights. This recognition, opposed by the Roman [p. 24] Church, is the real basis of international law. The Reformation was the means by which the personality of the peoples, the unity and independence of the state were first openly admitted. On this foundation, mainly at first in Protestant countries, the new science developed rapidly. Like the civil state and the Christian religion, international law may be called a peace institution.

Grotius, Puffendorf and Vattel.

In the beginning of the seventeenth century, Grotius laid the foundations of a code of universal law (De Jure Belli et Pacis, 1625) independent of differences of religion, in the hope that its recognition might simplify the intercourse between the newly formed nations. The primary object of this great work, written during the misery and horrors of the Thirty Years’ war, was expressly to draw attention to these evils and suggest some methods by which the severity of warfare might be mitigated. Grotius originally meant to explain only one chapter of the law of nations:[27] his book was to [p. 25] be called De Jure Belli, but there is scarcely any subject of international law which he leaves untouched. He obtained, moreover, a general recognition for the doctrine of the Law of Nature which exerted so strong an influence upon succeeding centuries; indeed, between these two sciences, as between international law and ethics, he draws no very sharp line of demarcation, although, on the whole, in spite of an unscientific, scholastic use of quotation from authorities, his treatment of the [p. 26] new field is clear and comprehensive. Grotius made the attempt to set up an ethical principle of right, in the stead of such doctrines of self-interest as had been held by many of the ancient writers. There was a law, he held, established in each state purely with a view to the interests of that state, but, besides this, there was another higher law in the interest of the whole society of nations. Its origin was divine; the reason of man commanded his obedience. This was what we call international law.[28]

Grotius distinctly holds, like Kant and Rousseau, and unlike Hobbes, that the state can never be regarded as a unity or institution separable from the people; the terms civitas, communitas, coetus, populus, he uses indiscriminately. But these nations, these independent units of society cannot live together side by side just as they like; they must recognise one another as members of a European society of states.[29] Law, he said, stands above force even in war, “which may only be begun to pursue the right;” and the beginning and manner of conduct of war rests on fixed laws and can be justified only in certain cases. War is not to be [p. 27] done away with: Grotius accepts it as fact,[30] (as Hobbes did later) as the natural method for settling the disputes which were bound constantly to arise between so many independent and sovereign nations. A terrible scourge it must ever remain, but as the only available form of legal procedure, it is sanctioned by the practice of states and not less by the law of nature and of nations. Grotius did not advance beyond this position. Every violation of the law of nations can be settled but in one way—by war, the force of the stronger.

The necessary distinction between law and ethics was drawn by Puffendorf,[31] a successor of Grotius who gave an outwardly systematic form to the doctrine of the great jurist, without adding to it [p. 28] either strength or completeness. His views, when they were not based upon the system of Grotius, were strongly influenced by the speculation of Hobbes, his chronological predecessor, to whom we shall have later occasion to refer. In the works of Vattel,[32] who was, next to Rousseau, the most celebrated of Swiss publicists, we find the theory of the customs and practice in war widely developed, and the necessity for humanising its methods and limiting its destructive effects upon neutral countries strongly emphasised. Grotius and Puffendorf, while they recommend acts of mercy, hold that there is legally no right which requires that a conquered enemy shall be spared. This is a matter of humanity alone. It is to the praise of Vattel that he did much to popularise among the highest and most powerful classes of society, ideas of humanity in warfare, and of the rights and obligations of nations. He is, moreover, the first to make a clear separation between this science and the Law of Nature. What, he asks, is international law as distinguished from the Law of Nature? What are the powers of a state and the duties of nations to one another? What are the causes of quarrel among nations, and what the means by which they can be settled without any sacrifice of dignity?

[p. 29]

They are, in the first place, a friendly conciliatory attitude; and secondly, such means of settlement as mediation, arbitration and Peace Congresses. These are the refuges of a peace-loving nation, in cases where vital interests are not at stake. “Nature gives us no right to use force, except where mild and conciliatory measures are useless.” (Law of Nations, II. Ch. xviii. § 331.) “Every power owes it in this matter to the happiness of human society to show itself ready for every means of reconciliation, in cases where the interests at stake are neither vital nor important.” (ibid. § 332.) At the same time, it is never advisable that a nation should forgive an insult which it has not the power to resent.

The Dream of a Perpetual Peace.

But side by side with this development and gradual popularisation of the new science of International Law, ideas of a less practical, but not less fruitful kind had been steadily making their way and obtaining a strong hold upon the popular mind. The Decree of Eternal Pacification of 1495 had abolished private war, one of the heavy curses of the Middle Ages. Why should it not be extended to banish warfare between states as well? Gradually one proposal after another was made [p. 30] to attain this end, or, at least, to smooth the way for its future realisation. The first of these in point of time is to be found in a somewhat bare, vague form in Sully’s Memoirs,[33] said to have been published in 1634. Half a century later the Quaker William Penn suggested an international tribunal of arbitration in the interests of peace.[34] But it was by the French Abbé St. Pierre that the problem of perpetual peace was fairly introduced into political literature: and this, in an age of cabinet and dynastic wars, while the dreary cost of the war of the Spanish succession was yet unpaid. St. Pierre was the first who really clearly realised and endeavoured to prove that the establishment of a permanent state of peace is not only in the interest of the weaker, but is required by the European society of nations and by the reason of man. From the beginning of the history of humanity, poets and prophets had cherished the “sweet dream” of a peaceful civilisation: it is in the form of a practical project that this idea is new.

The ancient world actually represented a state [p. 31] of what was almost perpetual war. This was the reality which confronted man, his inevitable doom, it seemed, as it had been pronounced to the fallen sinners of Eden. Peace was something which man had enjoyed once, but forfeited. The myth- and poetry-loving Greeks, and, later, the poets of Rome delighted to paint a state of eternal peace, not as something to whose coming they could look forward in the future, but as a golden age of purity whose records lay buried in the past, a paradise which had been, but which was no more. Voices, more scientific, were raised even in Greece in attempts, such as Aristotle’s, to show that the evolution of man had been not a course of degeneration from perfection, but of continual progress upwards from barbarism to civilisation and culture. But the change in popular thinking on this matter was due less to the arguments of philosophy than to a practical experience of the causes which operate in the interests of peace. The foundation of a universal empire under Alexander the Great gave temporary rest to nations heretofore incessantly at war. Here was a proof that the Divine Will had not decreed that man was to work out his punishment under unchanging conditions of perpetual warfare. This idea of a universal empire became the Greek ideal of a perpetual peace. Such an empire was, in the language of the Stoics, a world [p. 32] -state in which all men had rights of citizenship, in which all other nations were absorbed.

Parallel to this ideal among the Greeks, we find the hope in Israel of a Messiah whose coming was to bring peace, not only to the Jewish race, but to all the nations of the earth. This idea stands out in the sharpest contrast to the early nationalism of the Hebrew people, who regarded every stranger as an idolater and an enemy. The prophecies of Judaism, combined with the cosmopolitan ideas of Greece, were the source of the idea, which is expressed in the teaching of Christ, of a spiritual world-empire, an empire held together solely by the tie of a common religion.

This hope of peace did not actually die during the first thousand years of our era, nor even under the morally stagnating influences of the Middle Ages. When feudalism and private war were abolished in Europe, it wakened to a new life. Not merely in the mouths of poets and religious enthusiasts was the cry raised against war, but by scholars like Thomas More and Erasmus, jurists like Gentilis and Grotius, men high in the state and in the eyes of Europe like Henry IV. of France and the Duc de Sully or the Abbé de St. Pierre whose Projet de Paix Perpétuelle (1713)[35] [p. 33] obtained immediate popularity and wide-spread fame. The first half of the eighteenth century was already prepared to receive and mature a plan of this kind.

Henry IV. and St. Pierre.

The Grand Dessein of Henry IV. is supposed to have been formed by that monarch and reproduced in Sully’s Memoirs, written in 1634 and discovered nearly a century later by St. Pierre. The story goes that the Abbé found the book buried in an old garden. It has been shewn, however, that there is little likelihood that this project actually originated with the king, who probably corresponded fairly well to Voltaire’s picture of him as war hero of the Henriade. The plan was more likely conceived by Sully, and ascribed to the popular king for the sake of the better hearing and greater influence it might in this way be likely to have, and also because, thereby, it might be less likely to create offence in political circles. St. Pierre himself may or may not have been acquainted with the facts.

The so-called Grand Dessein of Henry IV. was, shortly, as follows.[36] It proposed to divide Europe [p. 34] between fifteen Powers,[37] in such a manner that the balance of power should be established and preserved. These were to form a Christian republic on the basis of the freedom and equality of its members, the armed forces of the federation being supported by fixed contribution. A general council, consisting of representatives from the fifteen states, was to make all laws necessary for cementing the union thus formed and for maintaining the order once established. It would also be the business of this senate to “deliberate on questions that might arise, to occupy themselves with discussing different interests, to settle quarrels amicably, to throw light upon and arrange all the civil, political and religious affairs of Europe, whether internal or foreign.” (Mémoires, vol. VI., p. 129 seq.)

This scheme of the king or his minister was expanded with great thoroughness and clear-sightedness by the Abbé St. Pierre: none of the many later plans for a perpetual peace has been so perfect in details. He proposes that there should be a permanent and perpetual union between, if possible, all Christian sovereigns—of whom he suggests nineteen, excluding the Czar—“to preserve unbroken peace in Europe,” and that a permanent Congress [p. 35] or senate should be formed by deputies of the federated states. The union should protect weak sovereigns, minors during a regency, and so on, and should banish civil as well as international war—it should “render prompt and adequate assistance to rulers and chief magistrates against seditious persons and rebels.” All warfare henceforth is to be waged between the troops of the federation—each nation contributing an equal number—and the enemies of European security, whether outsiders or rebellious members of the union. Otherwise, where it is possible, all disputes occurring within the union are to be settled by the arbitration of the senate, and the combined military force of the federation is to be applied to drive the Turks out of Europe. There is to be a rational rearrangement of boundaries, but after this no change is to be permitted in the map of Europe. The union should bind itself to tolerate the different forms of faith.

The objections to St. Pierre’s scheme are, many of them, obvious. He himself produces sixty-two arguments likely to be raised against his plan, and he examines these in turn with acuteness and eloquence. But there are other criticisms which he was less likely to be able to forestall. Of the nineteen states he names as a basis of the federation, some have disappeared and the governments of others have completely changed. Indeed St. Pierre’s [p. 36] scheme did not look far beyond the present. But it has besides a too strongly political character.[38] From this point of view, the Abbé’s plan amounts practically to a European coalition against the Ottoman Empire. Moreover, we notice with a smile that the French statesman and patriot is not lost in the cosmopolitan political reformer. “The kingdom of Spain shall not go out of the House of Bourbon!”[39] France is to enjoy more than the privileges of honour; she is to reap distinct material and political advantages from the union. Humanity is to be a brotherhood, but, in the federation of nations, France is to stand first.[40] We see that these “rêves d’un homme de bien,” as Cardinal Dubois called them, are not without their practical element. But the great mistake of St. Pierre is this: he actually thought that his plan could be put into execution in the near future, that an ideal of this kind was realisable at once.[41] “I, myself, [p. 37] form’d it,” he says in the preface, “in full expectation to see it one Day executed.” As Hobbes, says, “there can be nothing so absurd, but may be found in the books of philosophers.”[42] St. Pierre was not content to make his influence felt on the statesmen of his time and prepare the way for the abolition of all arbitrary forms of government. This was the flaw which drew down upon the good Abbé Voltaire’s sneering epigram[43] and the irony of Leibniz.[44] Here, above all, in this unpractical enthusiasm his scheme differs from that of Kant.

[p. 38]

Rousseau’s Criticism of St. Pierre.

Rousseau took St. Pierre’s project[45] much more seriously than either Leibniz or Voltaire. But sovereigns, he thought, are deaf to the voice of justice; the absolutism of princely power would never allow a king to submit to a tribunal of nations. Moreover war was, according to Rousseau’s experience, a matter not between nations, but between princes and cabinets. It was one of the ordinary pleasures of royal existence and one not likely to be voluntarily given up.[46] We know that history has not supported Rousseau’s contention. Dynastic wars are now no more. The Great Powers have shown themselves able to impose their [p. 39] own conditions, where the welfare and security of Europe have seemed to demand it. Such a development seemed impossible enough in the eighteenth century. In the military organisation of the nations of Europe and in the necessity of making their internal development subordinate to the care for their external security, Rousseau saw the cause of all the defects in their administration.[47] The formation of unions on the model of the Swiss Confederation or the German Bund would, he thought, be in the interest of all rulers. But great obstacles seemed to him to lie in the way of the realisation of such a project as that of St. Pierre. “Without doubt,” says Rousseau in conclusion, “the proposal of a perpetual peace is at present an absurd one.... It can only be put into effect by methods which are violent in themselves and dangerous to humanity. One cannot conceive of the possibility of a federative union being established, except by a revolution. [p. 40] And, that granted, who among us would venture to say whether this European federation is to be desired or to be feared? It would work, perhaps, more harm in a moment than it would prevent in the course of centuries.” (Jugement sur la Paix Perpétuelle.)

The Position of Hobbes.

The most profound and searching analysis of this problem comes from Immanuel Kant, whose indebtedness in the sphere of politics to Hobbes, Locke, Montesquieu and Rousseau it is difficult to overestimate. Kant’s doctrine of the sovereignty of the people comes to him from Locke through Rousseau. His explanation of the origin of society is practically that of Hobbes. The direct influence on politics of this philosopher, apart from his share in moulding the Kantian theory of the state, is one we cannot afford to neglect. His was a great influence on the new science just thrown on the world by Grotius, and his the first clear and systematic statement we have of the nature of society and the establishment of the state. The natural state of man, says Hobbes, is a state of war,[48] a [p. 41] bellum omnium contra omnes, where all struggle for honour and for preferment and the prizes to which every individual is by natural right equally entitled, but which can of necessity fall only to the few, the foremost in the race. Men hate and fear the society of their kind, but through this desire [p. 42] to excel are forced to seek it: only where there are many can there be a first. This state of things, this apparent sociability which is brought about by and coupled with the least sociable of instincts, becomes unendurable. “It is necessary to peace,” writes Hobbes (On Dominion, Ch. VI. 3) “that a man be so far forth protected against the violence of others, that he may live securely; that is, that he may have no just cause to fear others, so long as he doth them no injury. Indeed, to make men altogether safe from mutual harms, so as they cannot be hurt or injuriously killed, is impossible; and, therefore, comes not within deliberation.” But to protect them so far as is possible the state is formed. Hobbes has no great faith in human contracts or promises. Man’s nature is malicious and untrustworthy. A coercive power is necessary to guarantee this long-desired security within the community. “We must therefore,” he adds, “provide for our security, not by compacts, but by punishments; and there is then sufficient provision made, when there are so great punishments appointed for every injury, as apparently it prove a greater evil to have done it, than not to have done it. For all men, by a necessity of nature, choose that which to them appears to be the less evil.” (Op. cit., Ch. VI. 4.)

These precautions secure that relative peace [p. 43] within the state which is one of the conditions of the safety of the people. But it is, besides, the duty of a sovereign to guarantee an adequate protection to his subjects against foreign enemies. A state of defence as complete and perfect as possible is not only a national duty, but an absolute necessity. The following statement of the relation of the state to other states shows how closely Hobbes has been followed by Kant. “There are two things necessary,” says Hobbes, (On Dominion, Ch. XIII. 7) “for the people’s defence; to be warned and to be forearmed. For the state of commonwealths considered in themselves, is natural, that is to say, hostile.[49] Neither, if they cease from fighting, is it therefore to be called peace; but rather a breathing time, in which one enemy observing the motion and countenance of the other, values his security not according to pacts, but the forces and counsels of his adversary.”

Hobbes is a practical philosopher: no man was less a dreamer, a follower after ideals than he. He is, moreover, a pessimist, and his doctrine of the state is a political absolutism,[50] the form of govern [p. 44] ment which above all has been, and is, favourable to war. He would no doubt have ridiculed the idea of a perpetual peace between nations, had such a project as that of St. Pierre—a practical project, counting upon a realisation in the near future—been brought before him. He might not even have accepted it in the very much modified form which Kant adopts, that of an ideal—an unattainable ideal—towards which humanity could not do better than work. He expected the worst possible from man the individual. Homo homini lupus. The strictest absolutism, amounting almost to despotism, was required to keep the vicious propensities of the human animal in check. States he looked upon as units of the same kind, members also of a society. They had, and openly exhibited, the same faults as individual men. They too might be driven with a strong enough coercive force behind them, but not without it; and such a coercive force as this did not exist in a society of nations. Federation and federal troops are terms which represent ideas of comparatively recent origin. [p. 45] Without something of this kind, any enduring peace was not to be counted upon. International relations were and must remain at least potentially warlike in character. Under no circumstances could ideal conditions be possible either between the members of a state or between the states themselves. Human nature could form no satisfactory basis for a counsel of perfection.

Hence Hobbes never thought of questioning the necessity of war. It was in his eyes the natural condition of European society; but certain rules were necessary both for its conduct and, where this was compatible with a nation’s dignity and prosperity, for its prevention. He held that international law was only a part of the Law of Nature, and that this Law of Nature laid certain obligations upon nations and their kings. Mediation must be employed between disputants as much as possible, the person of the mediators of peace being held inviolate; an umpire ought to be chosen to decide a controversy, to whose judgment the parties in dispute agree to submit themselves; such an arbiter must be impartial. These are all what Hobbes calls precepts of the Law of Nature. And he appeals to the Scriptures in confirmation of his assertion that peace is the way of righteousness and that the laws of nature of which these are a few are also laws of the heavenly kingdom. But peace is like the [p. 46] straight path of Christian endeavour, difficult to find and difficult to keep. We must seek after it where it may be found; but, having done this and sought in vain, we have no alternative but to fall back upon war. Reason requires “that every man ought to endeavour peace,” (Lev. I. Ch. XIV.) “as far as he has hope of obtaining it; and when he cannot obtain it, that he may seek, and use, all helps, and advantages of war.”[51] This, says Hobbes elsewhere, (On Liberty, Ch. I. 15) is the dictate of right reason, the first and fundamental law of nature.

Kant’s Idea of a Perpetual Peace.

With regard to the problems of international law, Kant is of course a hundred and fifty years ahead of Hobbes. But he starts from the same point: his theory of the beginning of society is practically identical with that of the older philosopher. Men are by nature imperfect creatures, unsociable and untrustworthy, cursed by a love of glory, of possession, and of power, passions which make happiness something for ever unattainable by them. Hobbes is content to leave them here with their imperfections, and let a strong government [p. 47] help them out as it may. But not so Kant. He looks beyond man the individual, developing slowly by stages scarcely measurable, progressing at one moment, and the next, as it seems, falling behind: he looks beyond the individual, struggling and never attaining, to the race. Here Kant is no pessimist. The capacities implanted in man by nature are not all for evil: they are, he says, “destined to unfold themselves completely in the course of time, and in accordance with the end to which they are adapted.” (Idea of a Universal History from a Cosmopolitan Point of View, 1784. Prop. 1.) This end of humanity is the evolution of man from the stage of mere self-satisfied animalism to a high state of civilisation. Through his own reason man is to attain a perfect culture, intellectual and moral. In this long period of struggle, the potential faculties which nature or Providence has bestowed upon him reach their full development. The process in which this evolution takes place is what we call history.

To man nature has given none of the perfect animal equipments for self-preservation and self-defence which she has bestowed on others of her creatures. But she has given to him reason and freedom of will, and has determined that through these faculties and without the aid of instinct he shall win for himself a complete development of his capacities and natural endowments. It is, says [p. 48] Kant, no happy life that nature has marked out for man. He is filled with desires which he can never satisfy. His life is one of endeavour and not of attainment: not even the consciousness of the well-fought battle is his, for the struggle is more or less an unconscious one, the end unseen. Only in the race, and not in the individual, can the natural capacities of the human species reach full development. Reason, says Kant, (Prop. 2, op. cit.) “does not itself work by instinct, but requires experiments, exercise and instruction in order to advance gradually from one stage of insight to another. Hence each individual man would necessarily have to live an enormous length of time, in order to learn by himself how to make a complete use of all his natural endowments. Or, if nature should have given him but a short lease of life, as is actually the case, reason would then require an almost interminable series of generations, the one handing down its enlightenment to the other, in order that the seeds she has sown in our species may be brought at last to a stage of development which is in perfect accordance with her design.” Man the individual shall travel towards the land of promise and fight for its possession, but not he, nor his children, nor his children’s children shall inherit the land. “Only the latest comers can have the good fortune of inhabiting [p. 49] the dwelling which the long series of their predecessors have toiled—though,” adds Kant, “without any conscious intent—to build up without even the possibility of participating in the happiness which they were preparing.” (Proposition 3.)

The means which nature employs to bring about this development of all the capacities implanted in men is their mutual antagonism in society—what Kant calls the “unsocial sociableness of men, that is to say, their inclination to enter into society, an inclination which yet is bound up at every point with a resistance which threatens continually to break up the society so formed.” (Proposition 4.) Man hates society, and yet there alone he can develop his capacities; he cannot live there peaceably, and yet cannot live without it. It is the resistance which others offer to his inclinations and will—which he, on his part, shows likewise to the desires of others—that awakens all the latent powers of his nature and the determination to conquer his natural propensity to indolence and love of material comfort and to struggle for the first place among his fellow-creatures, to satisfy, in outstripping them, his love of glory and possession and power. “Without those, in themselves by no means lovely, qualities which set man in social opposition to man, so that each finds his selfish claims resisted by the selfishness of all the others, men would have lived [p. 50] on in an Arcadian shepherd life, in perfect harmony, contentment, and mutual love; but all their talents would forever have remained hidden and undeveloped. Thus, kindly as the sheep they tended, they would scarcely have given to their existence a greater value than that of their cattle. And the place among the ends of creation which was left for the development of rational beings would not have been filled. Thanks be to nature for the unsociableness, for the spiteful competition of vanity, for the insatiate desires of gain and power! Without these, all the excellent natural capacities of humanity would have slumbered undeveloped. Man’s will is for harmony; but nature knows better what is good for his species: her will is for dissension. He would like a life of comfort and satisfaction, but nature wills that he should be dragged out of idleness and inactive content and plunged into labour and trouble, in order that he may be made to seek in his own prudence for the means of again delivering himself from them. The natural impulses which prompt this effort,—the causes of unsociableness and mutual conflict, out of which so many evils spring,—are also in turn the spurs which drive him to the development of his powers. Thus, they really betray the providence of a wise Creator, and not the interference of some evil spirit which has meddled with the world which God has [p. 51] nobly planned, and enviously overturned its order.” (Proposition 4: Caird’s translation in The Critical Philosophy of Kant, Vol. II., pp. 550, 551.)

The problem now arises, How shall men live together, each free to work out his own development, without at the same time interfering with a like liberty on the part of his neighbour? The solution of this problem is the state. Here the liberty of each member is guaranteed and its limits strictly defined. A perfectly just civil constitution, administered according to the principles of right, would be that under which the greatest possible amount of liberty was left to each citizen within these limits. This is the ideal of Kant, and here lies the greatest practical problem which has presented itself to humanity. An ideal of this kind is difficult of realisation. But nature imposes no such duty upon us. “Out of such crooked material as man is made,” says Kant, “nothing can be hammered quite straight.” (Proposition 6.) We must make our constitution as good as we can and, with that, rest content.

The direct cause of this transition from a state of nature and conditions of unlimited freedom to civil society with its coercive and restraining forces is found in the evils of that state of nature as they are painted by Hobbes. A wild lawless freedom becomes impossible for man: he is compelled to [p. 52] seek the protection of a civil society. He lives in uncertainty and insecurity: his liberty is so far worthless that he cannot peacefully enjoy it. For this peace he voluntarily yields up some part of his independence. The establishment of the state is in the interest of his development to a higher civilisation. It is more—the guarantee of his existence and self-preservation. This is the sense, says Professor Paulsen, in which Kant like Hobbes regards the state as “resting on a contract,”[52] that [p. 53] is to say, on the free will of all.[53] Volenti non fit injuria. Only, adds Paulsen, we must remember that this contract is not a historical fact, as it seemed to some writers of the eighteenth century, but an “idea of reason”: we are speaking here not of the history of the establishment of the state, but of the reason of its existence. (Paulsen’s Kant, p. 354.)[54]

[p. 54]

In this civil union, self-sought, yet sought reluctantly, man is able to turn his most unlovable qualities to a profitable use. They bind this society together. They are the instrument by which he wins for himself self-culture. It is here with men, says Kant, as it is with the trees in a forest: “just because each one strives to deprive the other of air and sun, they compel each other to seek both above, and thus they grow beautiful and straight. Whereas those that, in freedom and isolation from one another, shoot out their branches at will, grow stunted and crooked and awry.” (Proposition 5, op. cit.) Culture, art, and all that is best in the social order are the fruits of that self-loving unsociableness in man.

The problem of the establishment of a perfect civil constitution cannot be solved, says this treatise (Idea for a Universal History), until the external relations of states are regulated in accordance with principles of right. For, even if the ideal internal constitution were attained, what end would it serve in the evolution of humanity, if commonwealths themselves were to remain like individuals in a state of nature, each existing in uncontrolled freedom, a law unto himself? This condition of things again cannot be permanent. Nature uses the same means as before to bring about a state of law and order. War, present or near at hand, the strain [p. 55] of constant preparation for a possible future campaign or the heavy burden of debt and devastation left by the last,—these are the evils which must drive states to leave a lawless, savage state of nature, hostile to man’s inward development, and seek in union the end of nature, peace. All wars are the attempts nature makes to bring about new political relations between nations, relations which, in their very nature, cannot be, and are not desired to be, permanent. These combinations will go on succeeding each other, until at last a federation of all powers is formed for the establishment of perpetual peace. This is the end of humanity, demanded by reason. Justice will reign, not only in the state, but in the whole human race when perpetual peace exists between the nations of the world.

This is the point of view of the Idea for a Universal History. But equally, we may say, law and justice will reign between nations, when a legally and morally perfect constitution adorns the state. External perpetual peace presupposes internal peace—peace civil, social, economic, religious. Now, when men are perfect—and what would this be but perfection—how can there be war? Cardinal Fleury’s only objection—no light one—to St. Pierre’s project was that, as even the most peace-loving could not avoid war, all men must first be men of noble character. This seems to be what is required [p. 56] in the treatise on Perpetual Peace. Kant demands, to a certain extent, the moral regeneration of man. There must be perfect honesty in international dealings, good faith in the interpretation and fulfilment of treaties and so on (Art. 1)[55]: and again, every state must have a republican constitution—a term by which Kant understands a constitution as nearly as possible in accordance with the spirit of right. (Art. 1.)[56] This is to say that we have to start with our reformation at home, look first to the culture and education and morals of our citizens, then to our foreign relations. This is a question of self-interest as well as of ethics. On the civil and religious liberty of a state depends its commercial success. Kant saw the day coming, when industrial superiority was to be identified with political pre-eminence. The state which does not look to the enlightenment and liberty of its subjects must fail in the race. But the advantages of a high state of civilisation are not all negative. The more highly developed the individuals who form a state, the more highly developed is its consciousness of its obligations to other nations. In the ignorance and barbarism of races lies the great obstacle to a reign of law among states. Uncivilised states cannot be conceived as members of a federation of Europe. [p. 57] First, the perfect civil constitution according to right: then the federation of these law-abiding Powers. This is the path which reason marks out. The treatise on Perpetual Peace seems to be in this respect more practical than the Idea for a Universal History. But it matters little which way we take it. The point of view is the same in both cases: the end remains the development of man towards good, the order of his steps in this direction is indifferent.

The Political and Social Conditions of Kant’s Time.

The history of the human race, viewed as a whole, Kant regards as the realisation of a hidden plan of nature to bring about a political constitution internally and externally perfect—the only condition under which the faculties of man can be fully developed. Does experience support this theory? Kant thought that, to a certain degree, it did. This conviction was not, however, a fruit of his experience of citizenship in Prussia, an absolute dynastic state, a military monarchy waging perpetual dynastic wars of the kind he most hotly condemned. Kant had no feeling of love to Prussia,[57] and little of a citizen’s patriotic pride, or even in [p. 58] terest, in its political achievements. This was partly because of his sympathy with republican doctrines: partly due to his love of justice and peculiar hatred of war,[58] a hatred based, no doubt, not less on principle than on a close personal experience of the wretchedness it brings with it. It was not the political and social conditions in which he lived which fostered Kant’s love of liberty and gave him inspiration, unless in the sense in which the mind reacts upon surrounding influences. Looking beyond [p. 59] Prussia to America, in whose struggle for independence he took a keen interest, and looking to France where the old dynastic monarchy had been succeeded by a republican state, Kant seemed to see the signs of a coming democratisation of the old monarchical society of Europe. In this growing influence on the state of the mass of the people who had everything to lose in war and little to gain by victory, he saw the guarantee of a future perpetual peace. Other forces too were at work to bring about this consummation. There was a growing consciousness that war, this costly means of settling a dispute, is not even a satisfactory method of settlement. Hazardous and destructive in its effect, it is also uncertain in its results. Victory is not always gain; it no longer signifies a land to be plundered, a people to be sold to slavery. It brings fresh responsibilities to a nation, at a time when it is not always strong enough to bear them. But, above all, Kant saw, even at the end of the eighteenth century, the nations of Europe so closely bound together by commercial interests that a war—and especially a maritime war where the scene of conflict cannot be to the same extent localised as on land—between any two of them could not but seriously affect the prosperity of the others.[59] He [p. 60] clearly realised that the spirit of commerce was the strongest force in the service of the maintenance of peace, and that in it lay a guarantee of future union.

This scheme of a federation of the nations of the world, in accordance with principles which would put an end to war between them, was one whose interest for Kant seemed to increase during the last twenty years of his life.[60] It was according to him an idea of reason, and, in his first essay on the subject—that of 1784—we see the place this ideal of a perpetual peace held in the Kantian system of philosophy. Its realisation is the realisation of the highest good—the ethical and political summum bonum, for here the aims of morals and politics coincide: only in a perfect development of his faculties in culture and in morals can man at last find true happiness. History is working towards the consummation of this end. A moral obligation lies on man to strive to establish conditions which bring its realisation nearer. It is the duty of statesmen to form a federative union as it was formerly the duty of individuals to enter the state. The moral law points the way here as clearly as in the sphere of pure ethics:—“Thou can’st, therefore thou ought’st.”

[p. 61]

Let us be under no misapprehension as to Kant’s attitude to the problem of perpetual peace. It is an ideal. He states plainly that he so regards it[61] and that as such it is unattainable. But this is the essence of all ideals: they have not the less value in shaping the life and character of men and nations on that account. They are not ends to be realised but ideas according to which we must live, regulative principles. We cannot, says Kant, shape our life better than in acting as if such ideas of reason have objective validity and there be an immortal life in which man shall live according to the laws of reason, in peace with his neighbour and in freedom from the trammels of sense.

Hence we are concerned here, not with an end, but with the means by which we might best set about attaining it, if it were attainable. This is the subject matter of the Treatise on Perpetual Peace (1795), a less eloquent and less purely philosophical essay than that of 1784, but throughout more systematic and practical. We have to do, not with the favourite dream of philanthropists like St. Pierre and Rousseau, but with a statement of the conditions on the fulfilment of which the transition to a reign of peace and law depends.

[p. 62]

The Conditions of the Realisation of the Kantian Ideal.

These means are of two kinds. In the first place, what evils must we set about removing? What are the negative conditions? And, secondly, what are the general positive conditions which will make the realisation of this idea possible and guarantee the permanence of an international peace once attained? These negative and positive conditions Kant calls Preliminary and Definitive Articles respectively, the whole essay being carefully thrown into the form of a treaty. The Preliminary Articles of a treaty for perpetual peace are based on the principle that anything that hinders or threatens the peaceful co-existence of nations must be abolished. These conditions have been classified by Kuno Fischer. Kant, he points out,[62] examines the principles of right governing the different sets of circumstances in which nations find themselves—namely, (a) while they are actually at war; (b) when the time comes to conclude a treaty of peace; (c) when they are living in a state of peace. The six Preliminary Articles fall naturally into these groups. War must not be conducted in such a manner as to increase national hatred and embitter a future [p. 63] peace. (Art. 6.)[63] The treaty which brings hostilities to an end must be concluded in an honest desire for peace. (Art. 1.)[64] Again a nation, when in a state of peace, must do nothing to threaten the political independence of another nation or endanger its existence, thereby giving the strongest of all motives for a fresh war. A nation may commit this injury in two ways: (1) indirectly, by causing danger to others through the growth of its standing army (Art. 3)[65]—always a menace to the state of peace—or by any unusual war preparations: and (2) through too great a supremacy of another kind, by amassing money, the most powerful of all weapons in warfare. The National Debt (Art. 4)[66] is another standing danger to the peaceful co-existence of nations. But, besides, we have the danger of actual attack. There is no right of intervention between nations. (Art. 5.)[67] Nor can states be inherited or conquered (Art. 2),[68] or in any way treated in a manner subversive of their independence and sovereignty as individuals. For a similar reason, armed troops cannot be hired and sold as things.

[p. 64]

These then are the negative conditions of peace.[69] There are, besides, three positive conditions:

[p. 65]

(a) The intercourse of nations is to be confined to a right of hospitality. (Art. 3.)[70] There is nothing new to us in this assertion of a right of way. The right to free means of international communication has in the last hundred years become a commonplace of law. And the change has been brought about, as Kant anticipated, not through an abstract respect for the idea of right, but through the pressure of purely commercial interests. Since Kant’s time the nations of Europe have all been more or less transformed from agricultural to commercial states whose interests run mainly in the same direction, whose existence and development depend necessarily upon “conditions of universal hospitality.” Commerce depends upon this freedom of international intercourse, and on commerce mainly depends our hope of peace.

(b) The first Definitive Article[71] requires that the constitution of every state should be republican. What Kant understands by this term is that, in the state, law should rule above force and that its [p. 66] constitution should be a representative one, guaranteeing public justice and based on the freedom and equality of its members and their mutual dependence on a common legislature. Kant’s demand is independent of the form of the government. A constitutional monarchy like that of Prussia in the time of Frederick the Great, who regarded himself as the first servant of the state and ruled with the wisdom and forethought which the nation would have had the right to demand from such an one—such a monarchy is not in contradiction to the idea of a true republic. That the state should have a constitution in accordance with the principles of right is the essential point.[72] To make [p. 67] this possible, the law-giving power must lie with the representatives of the people: there must be a complete separation, such as Locke and Rousseau demand, between the legislature and executive. Otherwise we have despotism. Hence, while Kant admitted absolutism under certain conditions, he rejected democracy where, in his opinion, the mass of the people was despot.

An internal constitution, firmly established on the principles of right, would not only serve to kill the seeds of national hatred and diminish the likelihood of foreign war. It would do more: it would destroy sources of revolution and discontent within the state. Kant, like many writers on this subject, does not directly allude to civil war[73] and [p. 68] the means by which it may be prevented or abolished. Actually to achieve this would be impossible: it is beyond the power of either arbitration or disarmament. But in a representative government and the liberty of a people lie the greatest safeguards against internal discontent. Civil peace and international peace must to a certain extent go hand in hand.

We come now to the central idea of the treatise: (c) the law of nations must be based upon a federation of free states. (Art. 2.)[74] This must be regarded as the end to which mankind is advancing. The problem here is not out of many nations to make one. This would be perhaps the surest way to attain peace, but it is scarcely practicable, and, in certain forms, it is undesirable. Kant is inclined to approve of the separation of nations by language and religion, by historical and social tradition and physical boundaries: nature seems to condemn the idea of a universal monarchy.[75] The only footing [p. 69] on which a thorough-going, indubitable system of international law is in practice possible is that of the society of nations: not the world-republic[76] the Greeks dreamt of, but a federation of states. Such a union in the interests of perpetual peace between nations would be the “highest political good.” The relation of the federated states to one another and to the whole would be fixed by cosmopolitan law: the link of self-interest which would bind them would again be the spirit of commerce.

This scheme of a perpetual peace had not escaped ridicule in the eighteenth century: the name of [p. 70] Kant protected it henceforth. The facts of history, even more conclusively than the voices of philosophers, soldiers and princes, show how great has been the progress of this idea in recent years. But it has not gained its present hold upon the popular mind without great and lasting opposition. Indeed we have here what must still be regarded as a controversial question. There have been, and are still, men who regard perpetual peace as a state of things as undesirable as it is unattainable. For such persons, war is a necessity of our civilisation: it is impossible that it should ever cease to exist. All that we can do, and there is no harm, nor any contradiction in the attempt, is to make wars shorter, fewer and more humane: the whole question, beyond this, is without practical significance. Others, on the other hand,—and these perhaps more thoughtful—regard war as hostile to culture, an evil of the worst kind, although a necessary evil. In peace, for them, lies the true ideal of humanity, although in any perfect form this cannot be realised in the near future. The extreme forms of these views are to be sought in what has been called in Germany “the philosophy of the barracks” which comes forward with a glorification of war for its own sake, and in the attitude of modern Peace Societies which denounce all war wholesale, without respect of causes or conditions.

[p. 71]

Hegel, Schiller and Moltke.

Hegel, the greatest of the champions of war, would have nothing to do with Kant’s federation of nations formed in the interests of peace. The welfare of a state, he held, is its own highest law; and he refused to admit that this welfare was to be sought in an international peace. Hegel lived in an age when all power and order seemed to lie with the sword. Something of the charm of Napoleonism seems to hang over him. He does not go the length of writers like Joseph de Maistre, who see in war the finger of God or an arrangement for the survival of the fittest—a theory, as far as regards individuals, quite in contradiction with the real facts, which show that it is precisely the physically unfit whom war, as a method of extermination, cannot reach. But, like Schiller and Moltke, Hegel sees in war an educative instrument, developing virtues in a nation which could not be fully developed otherwise, (much as pain and suffering bring patience and resignation and other such qualities into play in the individual), and drawing the nation together, making each citizen conscious of his citizenship, as no other influence can. War, he holds, leaves a nation always stronger than it was before; it buries causes of inner dissension, and consolidates the [p. 72] internal power of the state.[77] No other trial can, in the same way, show what is the real strength and weakness of a nation, what it is, not merely materially, but physically, intellectually and morally.

With this last statement most people will be inclined to agree. There is only a part of the truth in Napoleon’s dictum that “God is on the side of the biggest battalions”; or in the old saying that war requires three necessaries—in the first place, money; in the second place, money; and in the third, money. Money is a great deal: it is a necessity; but what we call national back-bone and character is more. So far we are with Hegel. But he goes further. In peace, says he, mankind would grow effeminate and degenerate in luxury. This opinion was expressed in forcible language in his own time by Schiller,[78] and in more [p. 73] recent years by Count Moltke. “Perpetual peace,” says a letter of the great general,[79] “is a dream and not a beautiful dream either: war is part of the divine order of the world. During war are developed the noblest virtues which belong to man—courage and self-denial, fidelity to duty and the spirit of self-sacrifice: the soldier is called upon to risk his life. Without war the world would sink in materialism.”[80] “Want and misery, disease, suffering and war,” he says elsewhere, “are all [p. 74] given elements in the Divine order of the universe.” Moltke’s eulogy of war, however, is somewhat modified by his additional statement that “the greatest kindness in war lies in its being quickly ended.” (Letter to Bluntschli, 11th Dec., [p. 75] 1880.)[81] The great forces which we recognise as factors in the moral regeneration of mankind are always slow of action as they are sure. War, if too quickly over, could not have the great moral influence which has been attributed to it. The explanation may be that it is not all that it naturally appears to a great and successful general. Hegel, Moltke, Trendelenburg, Treitschke[82] and the others—not Schiller[83] who was able to sing the blessings of peace as eloquently as of war—were apt to forget that war is as efficient a school for forming vices as virtues; and that, moreover, those virtues which military life is said to cultivate—courage, self-sacrifice and the rest—can be at least as perfectly developed in other trials. There are in human life dangers every day bravely met and overcome which are not less terrible than those which face the soldier, in whom patriotism may be less a sentiment than a duty, and whose cowardice must be dearly paid.

War under Altered Conditions.

The Peace Societies of our century, untiring supporters of a point of view diametrically opposite [p. 76] to that of Hegel, owe their existence in the first place to new ideas on the subject of the relative advantages and disadvantages of war, which again were partly due to changes in the character of war itself, partly to a new theory that the warfare of the future should be a war of free competition for industrial interests, or, in Herbert Spencer’s language, that the warlike type of mankind should make room for an industrial type. This theory, amounting in the minds of some thinkers to a fervid conviction, and itself, in a sense, the source of what has been contemptuously styled our British “shopkeeper’s policy” in Europe, was based on something more solid than mere enthusiasm. The years of peace which followed the downfall of Napoleon had brought immense increase in material wealth to countries like France and Britain. Something of the glamour had fallen away from the sword of the great Emperor. The illusive excitement of a desire for conquest had died: the glory of war had faded with it, but the burden still remained: its cost was still there, something to be calmly reckoned up and not soon to be forgotten. Europe was seen to be actually moving towards ruin. “We shall have to get rid of war in all civilised countries,” said Louis Philippe in 1843. “Soon no nation will be able to afford it.” War was not only becoming more costly. New conditions had altered it in other directions. [p. 77] With the development of technical science and its application to the perfecting of methods and instruments of destruction every new war was found to be bloodier than the last; and the day seemed to be in sight, when this very development would make war (with instruments of extermination) impossible altogether. The romance and picturesqueness with which it was invested in the days of hand-to-hand combat was gone. But, above all, war was now waged for questions fewer and more important than in the time of Kant. Napoleon’s successful appeal to the masses had suggested to Prussia the idea of consciously nationalising the army. Our modern national wars exact a sacrifice, necessarily much more heavy, much more reluctantly made than those of the past which were fought with mercenary troops. Such wars have not only greater dignity: they are more earnest, and their issue, as in a sense the issue of conflict between higher and lower types of civilisation, is speedier and more decisive.

In the hundred years since Kant’s death, much that he prophesied has come to pass, although sometimes by different paths than he anticipated. The strides made in recent years by commerce and the growing power of the people in every state have had much of the influence which he foretold. There is a greater reluctance to wage [p. 78] war.[84] But, unfortunately, as Professor Paulsen points out, the progress of democracy and the nationalisation of war have not worked merely in the direction of progress towards peace. War has now become popular for the first time. “The progress of democracy in states,” he says, (Kant, p. 364[85]) “has not only not done away with war, but has very greatly changed the feeling of people towards it. With the universal military service, introduced by the Revolution, war has become the people’s affair and popular, as it could not be in the case of dynastic wars carried on with mercenary troops.” In the people the love of peace is strong, but so too is the love of a fight, the love of victory.

It is in the contemplation of facts and conflicting tendencies like these that Peace Societies[86] have been formed. The peace party is, we may say, an eclectic body: it embraces many different sections of political opinion. There are those who hold, for instance, that peace is to be established on a basis of communism of property. There are others who insist on the establishment throughout Europe of a republican form of government, or again, on a [p. 79] redistribution of European territory in which Alsace-Lorraine is restored to France—changes of which at least the last two would be difficult to carry out, unless through international warfare. But these are not the fundamental general principles of peace workers. The members of this party agree in rejecting the principle of intervention, in demanding a complete or partial disarmament of the nations of Europe, and in requiring that all disputes between nations—and they admit the prospects of dispute—should be settled by means of arbitration. In how far are these principles useful or practicable?

The Value of Arbitration.

There is a strong feeling in favour of arbitration on the part of all classes of society. It is cheaper under all circumstances than war. It is a judgment at once more certain and more complete, excluding as far as possible the element of chance, leaving irritation perhaps behind it, but none of the lasting bitterness which is the legacy of every war. Arbitration has an important place in all peace projects except that of Kant, whose federal union would naturally fulfil the function of a tribunal of arbitration. St. Pierre, Jeremy Bentham,[87] [p. 80] Bluntschli[88] the German publicist, Professor Lorimer[89] and others among political writers,[90] and among rulers, Louis Napoleon and the Emperor Alexander I. of Russia, have all made proposals more or less ineffectual for the peaceful settlement of international disputes. A number of cases have already been decided by this means. But let us examine the questions which have been at issue. Of a hundred and thirty matters of dispute settled by arbitration since 1815 (cf. International Tribunals, published by the Peace Society, 1899) it will be seen that all, with the exception of one or two trifling cases of doubt as to the succession to certain titles or principalities, can be classified roughly under two heads—disputes as to the determination of boundaries or the possession of certain territory, and questions of claims for compensation and indemnities due either to individuals or states, arising from the seizure of fleets or merchant vessels, the insult or injury to private persons and so on—briefly, questions of money or of territory. [p. 81] These may fairly be said to be trifling causes, not touching national honour or great political questions. That they should have been settled in this way, however, shows a great advance. Smaller causes than these have made some of the bloodiest wars in history. That arbitration should have been the means of preventing even one war which would otherwise have been waged is a strong reason why we should fully examine its claims. “Quand l’institution d’une haute cour,” writes Laveleye, (Des causes actuelles de guerre en Europe et de l’arbitrage) “n’éviterait qu’une guerre sur vingt, il vaudrait encore la peine de l’établir.” But history shows us that there is no single instance of a supreme conflict having been settled otherwise than by war. Arbitration is a method admirably adapted to certain cases: to those we have named, where it has been successfully applied, to the interpretation of contracts, to offences against the Law of Nations—some writers say to trivial questions of honour—in all cases where the use of armed force would be impossible, as, for instance, in any quarrel in which neutralised countries[91] like Belgium or Luxembourg should take a principal part, or in a difference between two nations, such as (to take an extreme case) the United States and Switzerland, [p. 82] which could not easily engage in actual combat. These cases, which we cannot too carefully examine, show that what is here essential is that it should be possible to formulate a juridical statement of the conflicting claims. In Germany the Bundestag had only power to decide questions of law. Other disputes were left to be fought out. Questions on which the existence and vital honour of a state depend—any question which nearly concerns the disputants—cannot be reduced to any cut and dry legal formula of right and wrong. We may pass over the consideration that in some cases (as in the Franco-Prussian War) the delay caused by seeking mediation of any kind would deprive a nation of the advantage its state of military preparation deserved. And we may neglect the problem of finding an impartial judge on some questions of dispute, although its solution might be a matter of extreme difficulty, so closely are the interests of modern nations bound up in one another. How could the Eastern Question, for example, be settled by arbitration? It is impossible that such a means should be sufficient for every case. Arbitration in other words may prevent war, but can never be a substitute for war. We cannot wonder that this is so. So numerous and conflicting are the interests of states, so various are the grades of civilisation to which they have attained and the directions [p. 83] along which they are developing, that differences of the most vital kind are bound to occur and these can never be settled by any peaceful means at present known to Europe. This is above all true where the self-preservation[92] or independence of a people are concerned. Here the “good-will” of the nations who disagree would necessarily be wanting: there could be no question of the arbitration of an outsider.

But, indeed, looking away from questions so vital and on which there can be little difference of opinion, we are apt to forget, when we allow ourselves to talk extravagantly of the future of arbitration, that every nation thinks, or at least pretends to think, that it is in the right in every dispute in which it appears (cf. Kant: Perpetual Peace, p. 120.): and, as a matter of history, there [p. 84] has never been a conflict between civilised states in which an appeal to this “right” on the part of each has not been made. We talk glibly of the right and wrong of this question or of that, of the justice of this war, the iniquity of that. But what do these terms really mean? Do we know, in spite of the labour which has been spent on this question by the older publicists, which are the causes that justify a war? Is it not true that the same war might be just in one set of circumstances and unjust in another? Practically all writers on this subject, exclusive of those who apply the biblical doctrine of non-resistance, agree in admitting that a nation is justified in defending its own existence or independence, that this is even a moral duty as it is a fundamental right of a state. Many, especially the older writers, make the confident assertion that all wars of defence are just. But will this serve as a standard? Gibbon tells us somewhere, that Livy asserts that the Romans conquered the world in self-defence. The distinction between wars of aggression and defence is one very difficult to draw. The cause of a nation which waits to be actually attacked is often lost: the critical moment in its defence may be past. The essence of a state’s defensive power may lie in a readiness to strike the first blow, or its whole interests may be bound up in the necessity of fighting the matter out in its [p. 85] enemy’s country, rather than at home. It is not in the strictly military interpretation of the term “defensive”, but in its wider ethical and political sense that we can speak of wars of defence as just. But, indeed, we cannot judge these questions abstractly. Where a war is necessary, it matters very little whether it is just or not. Only the judgment of history can finally decide; and generally it seems at the time that both parties have something of right on their side, something perhaps too of wrong.[93]

[p. 86]

A consideration of difficulties like these brings us to a realisation of the fact that the chances are small that a nation, in the heat of a dispute, will admit the likelihood of its being in the wrong. To refuse to admit this is generally tantamount to a refusal to submit the difficulty to arbitration. And neither international law, nor the moral force of public opinion can induce a state to act contrary to what it believes to be its own interest. Moreover, as international law now stands, it is not a duty to have recourse to arbitration. This was made quite clear in the proceedings of the Peace Conference at the Hague in 1899.[94] It was strongly recommended that arbitration should be sought wherever it was possible, but, at the same time definitely stated, that this course could in no case be compulsory. In this respect things have not advanced beyond the position of the Paris Congress of 1856.[95] The wars waged in Europe subsequent to that date, have all been begun without previous attempt at mediation.

But the work of the peace party regarding the [p. 87] humaner methods of settlement is not to be neglected. The popular feeling which they have been partly the means of stimulating has no doubt done something to influence the action of statesmen towards extreme caution in the treatment of questions likely to arouse national passions and prejudices. Arbitration has undoubtedly made headway in recent years. Britain and America, the two nations whose names naturally suggest themselves to us as future centres of federative union, both countries whose industrial interests are numerous and complicated, have most readily, as they have most frequently, settled disputes in this practical manner. It has shown itself to be a policy as economical as it is business-like. Its value, in its proper place, cannot be overrated by any Peace Congress or by any peace pamphlet; but we have endeavoured to make it clear that this sphere is but a limited one. The “good-will” may not be there when it ought perhaps to appear: it will certainly not be there when any vital interest is at stake. But, even if this were not so and arbitration were the natural sequence of every dispute, no coercive force exists to enforce the decree of the court. The moral restraint of public opinion is here a poor substitute. Treaties, it is often said, are in the same position; but treaties have been broken, and will no doubt be broken again. We [p. 88] are moved to the conclusion that a thoroughly logical peace programme cannot stop short of the principle of federation. Federal troops are necessary to carry out the decrees of a tribunal of arbitration, if that court is not to run a risk of being held feeble and ineffectual. Except on some such basis, arbitration, as a substitute for war, stands on but a weak footing.

Disarmament.

The efforts of the Peace Society are directed with even less hope of complete success against another evil of our time, the crushing burden of modern armaments. We have peace at this moment, but at a daily increasing cost. The Peace Society is rightly concerned in pressing this point. It is not enough to keep off actual war: there is a limit to the price we can afford to pay even for peace. Probably no principle has cost Europe so much in the last century as that handed down from Rome:—“Si vis pacem, para bellum.” It is now a hundred and fifty years since Montesquieu[96] protested [p. 89] against this “new distemper” which was spreading itself over Europe; but never, in time of peace, has complaint been so loud or so general as now: and this, not only against the universal burden of taxation which weighs upon all nations alike, but, in continental countries, against the waste of productive force due to compulsory military service, a discontent which seems to strike at the very foundations of society. Vattel relates that in early times a treaty of peace generally stipulated that both parties should afterwards disarm. And there is no doubt that Kant was right in regarding standing armies as a danger to peace, not only as openly expressing the rivalry and distrust between nation and nation which Hobbes regards as the basis of international relations, but also as putting a power into the hand of a nation which it may some day have the temptation to abuse. A war-loving, overbearing spirit in a people thrives none the worse for a consciousness that its army or navy can hold its own with any other in Europe. Were it not the case that the essence of armed peace is that a high state of efficiency should be [p. 90] general, the danger to peace would be very great indeed. No doubt it is due to this fact that France has kept quietly to her side of the Rhine during the last thirty years. The annexation of Alsace-Lorraine was an immediate stimulus to the increase of armaments; but otherwise, just because of this greater efficiency and the slightly stronger military position of Germany, it has been an influence on the side of peace.

The Czar’s Rescript of 1898 gave a new stimulus to an interest in this question which the subsequent conference at the Hague was unable fully to satisfy. We are compelled to consider carefully how a process of simultaneous disarmament can actually be carried out, and what results might be anticipated from this step, with a view not only to the present but the future. Can this be done in accordance with the principles of justice? Organisations like a great navy or a highly disciplined army have been built up, in the course of centuries, at great cost and at much sacrifice to the nation. They are the fruit of years of wise government and a high record of national industry. Are such visible tokens of the culture and character and worth of a people to be swept away and Britain, France, Germany, Italy, Spain, Turkey to stand on the same level? And, even if no such ethical considerations should arise, on what method are [p. 91] we to proceed? The standard as well as the nature of armament depends in every state on its geographical conditions and its historical position. An ocean-bound empire like Britain is comparatively immune from the danger of invasion: her army can be safely despatched to the colonies, her fleet protects her at home, her position is one of natural defence. But Germany and Austria find themselves in exactly opposite circumstances, with the hard necessity imposed upon them of guarding their frontiers on every side. The safety of a nation like Germany is in the hands of its army: its military strength lies in an almost perfect mastery of the science of attack.

The Peace Society has hitherto made no attempt to face the difficulties inseparable from any attempt to apply a uniform method of treatment to peculiarities and conditions so conflicting and various as these. Those who have been more conscientious have not been very successful in solving them. Indeed, so constantly is military technique changing that it is difficult to prophesy wherein will lie, a few years hence, the essence of a state’s defensive power or what part the modern navy will play in this defence. No careful thinker would suggest, in the face of dangers threatening from the [p. 92] East,[97] a complete disarmament. The simplest of many suggestions made—but this on the basis of universal conscription—seems to be that the number of years or months of compulsory military service should be reduced to some fixed period. But this does not touch the difficulty of colonial empires[98] like Britain which might to a certain extent disarm, like their neighbours, in Europe, but would be compelled to keep an army for the defence of their colonies elsewhere. It is, in the meantime, inevitable that Europe should keep up a high standard of armament—this is, (and even if we had European federation, would remain) an absolute necessity as a protection against the yellow races, and in Europe itself there are at present elements hostile to the cause of peace. Alsace-Lorraine, Polish Prussia, Russian Poland and Finland are still, to a considerable degree, sources of discontent and dissatisfaction. But in Russia itself lies the great obstacle to a future European peace or European federation: we can scarcely picture Russia as a reliable member of such a union. That Russia should disarm is scarcely [p. 93] feasible, in view of its own interest: it has always to face the danger of rebellion in Poland and anarchy at home. But that Europe should disarm, before Russia has attained a higher civilisation, a consciousness of its great future as a north-eastern, inter-oceanic empire, and a government more favourable to the diffusion of liberty, is still less practicable.[99] We have here to fall back upon federation again. It is not impossible that, in the course of time, this problem may be solved and that the contribution to the federal troops of a European union may be regulated upon some equitable basis the form of which we cannot now well prophesy.

European federation would likewise meet all difficulties where a risk might be likely to occur of one nation intervening to protect another. As we have said (above, p. 64, note) nations are now-a-days slow to intervene in the interests of humanity: they are in general constrained to do so only by strong motives of self-interest, and when these are not at hand they are said to refrain from respect for another’s right of independent action. Actually a state which is actuated by less selfish impulses is apt to lose considerably more than it [p. 94] gains, and the feeling of the people expresses itself strongly against any quixotic or sentimental policy. It is not impossible that the Powers may have yet to intervene to protect Turkey against Russia. Such a step might well be dictated purely by a proper care for the security of Europe; but wars of this kind seem not likely to play an important part in the near future.

We have said that the causes of difference which may be expected to disturb the peace of Europe are now fewer. A modern sovereign no longer spends his leisure time in the excitement of slaying or seeing slain. He could not, if he would. His honour and his vanity are protected by other means: they play no longer an important part in the affairs of nations. The causes of war can no more be either trifling or personal. Some crises there are, which are ever likely to be fatal to peace. There present themselves, in the lives of nations, ideal ends for which everything must be sacrificed: there are rights which must at all cost be defended. The question of civil war we may neglect: liberty and wise government are the only medicine for social discontent, and much may be hoped from that in the future. But now, looking beyond the state to the great family of civilised nations, we may say that the one certain cause of war between them or of rebellion within a future federated union will be a [p. 95] menace to the sovereign rights, the independence and existence of any member of that federation. Other causes of quarrel offer a more hopeful prospect. Some questions have been seen to be specially fitted for the legal procedure of a tribunal of arbitration, others to be such as a federal court would quickly settle. The preservation of the balance of power which Frederick the Great regarded as the talisman of peace in Europe—a judgment surely not borne out by experience—is happily one of the causes of war which are of the past. Wars of colonisation, such as would be an attempt on the part of Russia to conquer India, seem scarcely likely to recur except between higher and lower races. The cost is now-a-days too great. Political wars, wars for national union and unity, of which there were so many during the past century, seem at present not to be near at hand; and the integration of European nations—what may be called the great mission of war—is, for the moment, practically complete; for it is highly improbable that either Alsace-Lorraine or Poland—still less Finland—will be the cause of a war of this kind.

Our hope lies in a federated Europe. Its troops would serve to preserve law and order in the country from which they were drawn and to protect its colonies abroad; but their higher function would [p. 96] be to keep peace in Europe, to protect the weaker members of the Federation and to enforce the decision of the majority, either, if necessary, by actual war, or by the mere threatening demonstrations of fleets, such as have before proved effectual.

We have carefully considered what has been attempted by peace workers, and we have now to take note that all the results of the last fifty years are not to be attributed to their conscientious but often ill-directed labour. The diminution of the causes of war is to be traced less to the efforts of the Peace Society, (except indirectly, in so far as they have influenced the minds of the masses) than to the increasing power of the people themselves. The various classes of society are opposed to violent methods of settlement, not in the main from a conviction as to the wrongfulness of war or from any fanatical enthusiasm for a brotherhood of nations, but from self-interest. War is death to the industrial interests of a nation. It is vain to talk, in the language of past centuries, of trade between civilised countries being advanced and markets opened up or enlarged by this means.[100] [p. 97] Kings give up the dream of military glory and accept instead the certainty of peaceful labour and industrial progress, and all this (for we may believe that to some monarchs it is much) from no enthusiastic appreciation of the efforts of Peace Societies, from no careful examination of the New Testament nor inspired interpretation of its teaching. It is self-interest, the prosperity of the country—patriotism, if you will—that seems better than war.

What may be expected from Federation.

Federation and federation alone can help out the programme of the Peace Society. It cannot be pretended that it will do everything. To state the worst at once, it will not prevent war. Even the federations of the states of Germany and America, bound together by ties of blood and language and, in the latter case, of sentiment, were not strong enough within to keep out dissension and disunion.[101] Wars would not cease, but they would become much less frequent. “Why is there no longer war between England and Scotland? Why did Prussian and Hanoverian fight side by side in 1870, though they had fought [p. 98] against each other only four years before?... If we wish to know how war is to cease, we should ask ourselves how it has ceased” (Professor D. G. Ritchie, op. cit., p. 169). Wars between different grades of civilisation are bound to exist as long as civilisation itself exists. The history of culture and of progress has been more or less a history of war. A calm acceptance of this position may mean to certain short-sighted, enthusiastic theorists an impossible sacrifice of the ideal; but, the sacrifice once made, we stand on a better footing with regard to at least one class of arguments against a federation of the world. Such a union will lead, it is said, to an equality in culture, a sameness of interests fatal to progress; all struggle and conflict will be cast out of the state itself; national characteristics and individuality will be obliterated; the lamb and the wolf will lie down together: stagnation will result, intellectual progress will be at an end, politics will be no more, history will stand still. This is a sweeping assertion, an alarming prophecy. But a little thought will assure us that there is small cause for apprehension. There can be no such standstill, no millennium in human affairs. A gradual smoothing down of sharply accentuated national characteristics there might be: this is a result which a freer, more friendly intercourse between nations would be very [p. 99] likely to produce. But conflicting interests, keen rivalry in their pursuit, difference of culture and natural aptitude, and all or much of the individuality which language and literature, historical and religious traditions, even climatic and physical conditions produce are bound to survive until the coming of some more overwhelming and far-spreading revolution than this. It would not be well if it were otherwise, if those “unconscious and invisible peculiarities” in which Fichte sees the hand of God and the guarantee of a nation’s future dignity, virtue and merit should be swept away. (Reden an die deutsche Nation,[102] 1807.) Nor is stagnation to be feared. “Strife,” said the old philosopher, “is the father of all things.” There can be no lasting peace in the processes of nature and existence. It has been in the constant rivalry between classes within themselves, and in the struggle for existence with other races that great nations have reached the highwater mark of their development. A perpetual peace in international relations we may—nay, surely will—one day have, but eternity will not see the end to the feverish unrest within the state and the jealous competition and distrust between individuals, groups and classes of society. Here there must ever be perpetual war.

It was only of this political peace between civil [p. 100] ised nations that Kant thought.[103] In this form it is bound to come. The federation of Europe will follow the federation of Germany and of Italy, not only because it offers a solution of many problems which have long taxed Europe, but because great men and careful thinkers believe in it.[104] It may not come quickly, but such men can afford to wait. “If I were legislator,” cried Jean Jacques Rousseau, “I should not say what ought to be done, but I would do it.” This is the attitude of the unthinking, unpractical enthusiast. The wish is not enough: the will is not enough. The mills of God must take their own time: no hope or faith of ours, no struggle or labour even can hurry them.

It is a misfortune that the Peace Society has identified itself with so narrow and uncritical an attitude towards war, and that the copious elo [p. 101] quence of its members is not based upon a consideration of the practical difficulties of the case. This well-meaning, hard working and enthusiastic body would like to do what is impossible by an impossible method. The end which it sets for itself is an unattainable one. But this need not be so. To make unjustifiable aggression difficult, to banish unworthy pretexts for making war might be a high enough ideal for any enthusiasm and offer scope wide enough for the labours of any society. But the Peace Society has not contented itself with this great work. Through its over-estimation of the value of peace,[105] its cause has been injured and much of its influence has been weakened or lost. Our age is one which sets a high value upon human life; and to this change of thinking may be traced our modern reform in the methods of war and all that has been done for the alleviation of suffering by the great Conventions of recent years. For the eyes of most people war is merely a hideous spectacle of bloodshed and deliberate destruction of life: this is its obvious side. But it is possible to exaggerate this confessedly great evil. Peace has its sacrifices as well as war: the [p. 102] progress of humanity requires that the individual should often be put aside for the sake of lasting advantage to the whole. An opposite view can only be reckoned individualistic, perhaps materialistic. “The reverence for human life,” says Martineau, (Studies of Christianity, pp. 352, 354) “is carried to an immoral idolatry, when it is held more sacred than justice and right, and when the spectacle of blood becomes more horrible than the sight of desolating tyrannies and triumphant hypocrisies.... We have, therefore, no more doubt that a war may be right, than that a policeman may be a security for justice, and we object to a fortress as little as to a handcuff.”

The Peace Society are not of this opinion: they greatly doubt that a war may be right, and they rarely fail to take their doubts to the tribunal of Scripture. Their efforts are well meant, this piety may be genuine enough; but a text is rarely a proof of anything, and in any case serves one man in as good stead as another. We remember that “the devil can cite Scripture for his purpose.” This unscientific method of proof or persuasion has ever been widely popular. It is a serious examination of the question that we want, a more careful study of its actual history and of the possibilities of human nature; less vague, exaggerated language about what ought to be done, and a realisation of [p. 103] what has been actually achieved; above all, a clear perception of what may fairly be asked from the future.

It used to be said—is perhaps asserted still by the war-lovers—that there was no path to civilisation which had not been beaten by the force of arms, no height to which the sword had not led the way. The inspiration of war was upon the great arts of civilisation: its hand was upon the greatest of the sciences. These obligations extended even to commerce. War not only created new branches of industry, it opened new markets and enlarged the old. These are great claims, according to which war might be called the moving principle of history. If we keep our eyes fixed upon the history of the past, they seem not only plausible: they are in a great sense true. Progress did tread at the heels of the great Alexander’s army: the advance of European culture stands in the closest connection with the Crusades. But was this happy compensation for a miserable state of affairs not due to the peculiarly unsocial conditions of early times and the absence of every facility for the interchange of ideas or material advantages? It is inconceivable that now-a-days[106] any aid to the development of thought in Europe should come from war. The [p. 104] old adage, in more than a literal sense, has but too often been proved true:—“Inter arma, Musae silent.” Peace is for us the real promoter of culture.

We have to endeavour to take an intermediate course between uncritical praise and wholesale condemnation, between extravagant expectation and unjustifiable pessimism. War used to be the rule: it is now an overwhelming and terrible exception—an interruption to the peaceful prosperous course of things, inflicting unlimited suffering and temporary or lasting loss. Its evils are on the surface, apparent to the most unthinking observer. The day may yet dawn, when Europeans will have learned to regard the force of arms as an instrument for the civilisation of savage or half-savage races, and war within their continent as civil war, necessary and justifiable sometimes perhaps, but still a blot upon their civilisation and brotherhood as men. Such a suggestion rings strangely. But the great changes, which the roll of centuries has marked, once came upon the world not less unexpectedly. How far off must the idea of a civil peace have seemed to small towns and states of Europe in the fifteenth century! How strange, only a century [p. 105] ago, would the idea of applying steam power or electrical force have seemed to ourselves! Let us not despair. War has played a great part in the history of the world: it has been ever the great architect of nations, the true mother of cities. It has justified itself to-day in the union of kindred peoples, the making of great empires. It may be that one decisive war may yet be required to unite Europe. May Europe survive that struggle and go forward fearlessly to her great future! A peaceful future that may not be. It must never be forgotten that war is sometimes a moral duty, that it is ever the natural sequence of human passion and human prejudice. An unbroken peace we cannot and do not expect; but it is this that we must work for. As Kant says, we must keep it before us as an ideal.

TRANSLATION[107]. “PERPETUAL PEACE”[108]↩

We need not try to decide whether this satirical inscription, (once found on a Dutch innkeeper’s sign-board above the picture of a churchyard) is aimed at mankind in general, or at the rulers of states in particular, unwearying in their love of war, or perhaps only at the philosophers who cherish the sweet dream of perpetual peace. The author of the present sketch would make one stipulation, however. The practical politician stands upon a definite footing with the theorist: with great self-complacency he looks down upon him as a mere pedant whose empty ideas can threaten no danger to the state (starting as it does from principles derived from experience), and who may always be permitted to [p. 107] knock down his eleven skittles at once without a worldly-wise statesman needing to disturb himself. Hence, in the event of a quarrel arising between the two, the practical statesman must always act consistently, and not scent danger to the state behind opinions ventured by the theoretical politician at random and publicly expressed. With which saving clause (clausula salvatoria) the author will herewith consider himself duly and expressly protected against all malicious misinterpretation.

FIRST SUPPLEMENT. CONCERNING THE GUARANTEE OF PERPETUAL PEACE↩

This guarantee is given by no less a power than the great artist nature (natura dædala rerum) in whose mechanical course is clearly exhibited a predetermined design to make harmony spring from human discord, even against the will of man. Now this design, although called Fate when looked upon as the compelling force of a cause, the laws of whose operation are unknown to us, is, when considered as the purpose manifested in the course of nature, called Providence,[135] as the deep [p. 144] -lying wisdom of a Higher Cause, directing itself towards the ultimate practical end of the human race and predetermining the course of things with a view to its realisation. This Providence we do [p. 145] not, it is true, perceive in the cunning contrivances [Kunstanstalten] of nature; nor can we even conclude from the fact of their existence that it is there; but, as in every relation between the form of things and their final cause, we can, and must, supply the thought of a Higher Wisdom, in order that we may be able to form an idea of the possible existence of these products after the analogy of human works of art [Kunsthand [p. 146] lungen].[136] The representation to ourselves of the relation and agreement of these formations of nature to the moral purpose for which they were made and which reason directly prescribes to us, is an Idea, it is true, which is in theory superfluous; but in practice it is dogmatic, and its objective reality is well established.[137] Thus we see, for example, with regard to the ideal [Pflichtbegriff] of perpetual peace, that it is our duty to make use of the mechanism of nature for the realisation of that end. Moreover, in a case like this where we are interested merely in the theory and not in the religious question, the use of the word “nature” is more appropriate than that of “providence”, in view of the limitations of human reason, which, in considering the relation of effects to their causes, must keep within the limits of possible experience. And the term “nature” is also less presumptuous than the other. To speak of a Providence knowable by us would be boldly to put on the wings of Icarus in order to draw near to the mystery of its unfathomable purpose.

Before we determine the surety given by nature more exactly, we must first look at what ultimately makes this guarantee of peace necessary—the [p. 147] circumstances in which nature has carefully placed the actors in her great theatre. In the next place, we shall proceed to consider the manner in which she gives this surety.

The provisions she has made are as follow: (1) she has taken care that men can live in all parts of the world; (2) she has scattered them by means of war in all directions, even into the most inhospitable regions, so that these too might be populated; (3) by this very means she has forced them to enter into relations more or less controlled by law. It is surely wonderful that, on the cold wastes round the Arctic Ocean, there is always to be found moss for the reindeer to scrape out from under the snow, the reindeer itself either serving as food or to draw the sledge of the Ostiak or Samoyedes. And salt deserts which would otherwise be left unutilised have the camel, which seems as if created for travelling in such lands. This evidence of design in things, however, is still more clear when we come to know that, besides the fur-clad animals of the shores of the Arctic Ocean, there are seals, walruses and whales whose flesh furnishes food and whose oil fire for the dwellers in these regions. But the providential care of nature excites our wonder above all, when we hear of the driftwood which is carried—whence no one knows—to these treeless shores: for without the [p. 148] aid of this material the natives could neither construct their craft, nor weapons, nor huts for shelter. Here too they have so much to do, making war against wild animals, that they live at peace with one another. But what drove them originally into these regions was probably nothing but war.

Of animals, used by us as instruments of war, the horse was the first which man learned to tame and domesticate during the period of the peopling of the earth; the elephant belongs to the later period of the luxury of states already established. In the same way, the art of cultivating certain grasses called cereals—no longer known to us in their original form—and also the multiplication and improvement, by transplanting and grafting, of the original kinds of fruit—in Europe, probably only two species, the crab-apple and wild pear—could only originate under the conditions accompanying established states where the rights of property are assured. That is to say it would be after man, hitherto existing in lawless liberty, had advanced beyond the occupations of a hunter,[138] a fisherman [p. 149] or a shepherd to the life of a tiller of the soil, when salt and iron were discovered,—to become, perhaps, the first articles of commerce between different peoples,—and were sought far and near. In this way the peoples would be at first brought into peaceful relation with one another, and so come to an understanding and the enjoyment of friendly intercourse, even with their most distant neighbours.

Now while nature provided that men could live on all parts of the earth, she also at the same time despotically willed that they should live everywhere on it, although against their own inclination and even although this imperative did not presuppose an idea of duty which would compel obedience to nature with the force of a moral law. But, to attain this end, she has chosen war. So we see certain peoples, widely separated, whose common [p. 150] descent is made evident by affinity in their languages. Thus, for instance, we find the Samoyedes on the Arctic Ocean, and again a people speaking a similar language on the Altai Mts., 200 miles [Meilen][139] off, between whom has pressed in a mounted tribe, warlike in character and of Mongolian origin, which has driven one branch of the race far from the other, into the most inhospitable regions where their own inclination would certainly not have carried them.[140] In the same way, through the intrusion of the Gothic and Sarmatian tribes, the Finns in the most northerly regions of Europe, whom we call Laplanders, have been separated by as great a distance from the Hungarians, with whose language their own is allied. And what but war can have brought the Esquimos to the north of America, a race quite distinct from those of that country and probably European adventurers of [p. 151] prehistoric times? And war too, nature’s method of populating the earth, must have driven the Pescherais[141] in South America as far as Patagonia. War itself, however, is in need of no special stimulating cause, but seems engrafted in human nature, and is even regarded as something noble in itself to which man is inspired by the love of glory apart from motives of self-interest. Hence, among the savages of America as well as those of Europe in the age of chivalry, martial courage is looked upon as of great value itself, not merely when a war is going on, as is reasonable enough, but in order that there should be war: and thus war is often entered upon merely to exhibit this quality. So that an intrinsic dignity is held to attach to war in itself, and even philosophers eulogise it as an ennobling, refining influence on humanity, unmindful of the Greek proverb, “War is evil, in so far as it makes more bad people than it takes away.”

So much, then, of what nature does for her own ends with regard to the human race as members of the animal world. Now comes the question which touches the essential points in this design of a perpetual peace:—“What does nature do in this respect with reference to the end which man’s own [p. 152] reason sets before him as a duty? and consequently what does she do to further the realisation of his moral purpose? How does she guarantee that what man, by the laws of freedom, ought to do and yet fails to do, he will do, without any infringement of his freedom by the compulsion of nature and that, moreover, this shall be done in accordance with the three forms of public right—constitutional or political law, international law and cosmopolitan law?” When I say of nature that she wills that this or that should take place, I do not mean that she imposes upon us the duty to do it—for only the free, unrestrained, practical reason can do that—but that she does it herself, whether we will or not. “Fata volentem ducunt, nolentem trahunt.”

1. Even if a people were not compelled through internal discord to submit to the restraint of public laws, war would bring this about, working from without. For, according to the contrivance of nature which we have mentioned, every people finds another tribe in its neighbourhood, pressing upon it in such a manner that it is compelled to form itself internally into a state to be able to defend itself as a power should. Now the republican constitution is the only one which is perfectly adapted to the rights of man, but it is also the most difficult to establish and still more to maintain. So generally is this recognised that people [p. 153] often say the members of a republican state would require to be angels,[142] because men, with their self-seeking propensities, are not fit for a constitution of so sublime a form. But now nature comes to the aid of the universal, reason-derived will which, much as we honour it, is in practice powerless. And this she does, by means of these very self-seeking propensities, so that it only depends—and so much lies within the power of man—on a good organisation of the state for their forces to be so pitted against one another, that the one may check the destructive activity of the other or neutralise its effect. And hence, from the standpoint of reason, the result will be the same as if both forces did not exist, and each individual is compelled to be, if not a morally good man, yet at least a good citizen. The problem of the formation of the state, hard as it may sound, is not insoluble, even for a [p. 154] race of devils, granted that they have intelligence. It may be put thus:—“Given a multitude of rational beings who, in a body, require general laws for their own preservation, but each of whom, as an individual, is secretly inclined to exempt himself from this restraint: how are we to order their affairs and how establish for them a constitution such that, although their private dispositions may be really antagonistic, they may yet so act as a check upon one another, that, in their public relations, the effect is the same as if they had no such evil sentiments.” Such a problem must be capable of solution. For it deals, not with the moral reformation of mankind, but only with the mechanism of nature; and the problem is to learn how this mechanism of nature can be applied to men, in order so to regulate the antagonism of conflicting interests in a people that they may even compel one another to submit to compulsory laws and thus necessarily bring about the state of peace in which laws have force. We can see, in states actually existing, although very imperfectly organised, that, in externals, they already approximate very nearly to what the Idea of right prescribes, although the principle of morality is certainly not the cause. A good political constitution, however, is not to be expected as a result of progress in morality; but rather, conversely, the good moral condition of a nation is to be looked for, as one of [p. 155] the first fruits of such a constitution. Hence the mechanism of nature, working through the self-seeking propensities of man (which of course counteract one another in their external effects), may be used by reason as a means of making way for the realisation of her own purpose, the empire of right, and, as far as is in the power of the state, to promote and secure in this way internal as well as external peace. We may say, then, that it is the irresistible will of nature that right shall at last get the supremacy. What one here fails to do will be accomplished in the long run, although perhaps with much inconvenience to us. As Bouterwek says, “If you bend the reed too much it breaks: he who would do too much does nothing.”

2. The idea of international law presupposes the separate existence of a number of neighbouring and independent states; and, although such a condition of things is in itself already a state of war, (if a federative union of these nations does not prevent the outbreak of hostilities) yet, according to the Idea of reason, this is better than that all the states should be merged into one under a power which has gained the ascendency over its neighbours and gradually become a universal monarchy.[143] For the wider the sphere of their jurisdic [p. 156] tion, the more laws lose in force; and soulless despotism, when it has choked the seeds of good, at last sinks into anarchy. Nevertheless it is the desire of every state, or of its ruler, to attain to a permanent condition of peace in this very way; that is to say, by subjecting the whole world as far as possible to its sway. But nature wills it otherwise. She employs two means to separate nations, and prevent them from intermixing: namely, the differences of language and of religion.[144] These differences bring with them a tendency to mutual hatred, and furnish pretexts for waging war. But, none the less, with the growth of culture and the gradual advance of men to greater unanimity of principle, they lead to concord in a state of peace which, unlike the despotism we have spoken of, (the churchyard of freedom) does not arise from the weakening of all forces, but is brought into being and secured through the equilibrium of these forces in their most active rivalry.

[p. 157] 3. As nature wisely separates nations which the will of each state, sanctioned even by the principles of international law, would gladly unite under its own sway by stratagem or force; in the same way, on the other hand, she unites nations whom the principle of a cosmopolitan right would not have secured against violence and war. And this union she brings about through an appeal to their mutual interests. The commercial spirit cannot co-exist with war, and sooner or later it takes possession of every nation. For, of all the forces which lie at the command of a state, the power of money is probably the most reliable. Hence states find themselves compelled—not, it is true, exactly from motives of morality—to further the noble end of peace and to avert war, by means of mediation, wherever it threatens to break out, just as if they had made a permanent league for this purpose. For great alliances with a view to war can, from the nature of things, only very rarely occur, and still more seldom succeed.

In this way nature guarantees the coming of perpetual peace, through the natural course of human propensities: not indeed with sufficient certainty to enable us to prophesy the future of this ideal theoretically, but yet clearly enough for practical purposes. And thus this guarantee of nature makes it a duty that we should labour for this end, an end which is no mere chimera.

[p. 158]

SECOND SUPPLEMENT. A SECRET ARTICLE FOR PERPETUAL PEACE↩

A secret article in negotiations concerning public right is, when looked at objectively or with regard to the meaning of the term, a contradiction. When we view it, however, from the subjective standpoint, with regard to the character and condition of the person who dictates it, we see that it might quite well involve some private consideration, so that he would regard it as hazardous to his dignity to acknowledge such an article as originating from him.

The only article of this kind is contained in the following proposition:—“The opinions of philosophers, with regard to the conditions of the possibility of a public peace, shall be taken into consideration by states armed for war.”

It seems, however, to be derogatory to the dignity of the legislative authority of a state—to which we must of course attribute all wisdom—to ask advice from subjects (among whom stand philosophers) about the rules of its behaviour to other states. At the same time, it is very advisable that this should be done. Hence the state will silently invite suggestion for this purpose, while at the same time keeping the fact secret. This amounts to [p. 159] saying that the state will allow philosophers to discuss freely and publicly the universal principles governing the conduct of war and establishment of peace; for they will do this of their own accord, if no prohibition is laid upon them.[145] The arrangement between states, on this point, does not require that a special agreement should be made, merely for this purpose; for it is already involved in the obligation imposed by the universal reason of man which gives the moral law. We would not be understood to say that the state must give a preference to the principles of the philosopher, rather than to the opinions of the jurist, the representative of state authority; but only that he should be heard. The latter, who has chosen for a symbol the scales of right and the sword of justice,[146] generally uses that sword not merely to keep off all outside influences from the scales; for, when one pan of the balance will not go down, he throws his sword into it; and then Væ victis! The jurist, not being [p. 160] a moral philosopher, is under the greatest temptation to do this, because it is his business only to apply existing laws and not to investigate whether these are not themselves in need of improvement; and this actually lower function of his profession he looks upon as the nobler, because it is linked to power (as is the case also in both the other faculties, theology and medicine). Philosophy occupies a very low position compared with this combined power. So that it is said, for example, that she is the handmaid of theology; and the same has been said of her position with regard to law and medicine. It is not quite clear, however, “whether she bears the torch before these gracious ladies, or carries the train.”

That kings should philosophise, or philosophers become kings, is not to be expected. But neither is it to be desired; for the possession of power is inevitably fatal to the free exercise of reason. But it is absolutely indispensable, for their enlightenment as to the full significance of their vocations, that both kings and sovereign nations, which rule themselves in accordance with laws of equality, should not allow the class of philosophers to disappear, nor forbid the expression of their opinions, but should allow them to speak openly. And since this class of men, by their very nature, are incapable of instigating rebellion or forming unions for purposes of political agitation, they should not be suspected of propagandism.

[p. 161]

APPENDIX I. ON THE DISAGREEMENT BETWEEN MORALS AND POLITICS WITH REFERENCE TO PERPETUAL PEACE↩

In an objective sense, morals is a practical science, as the sum of laws exacting unconditional obedience, in accordance with which we ought to act. Now, once we have admitted the authority of this idea of duty, it is evidently inconsistent that we should think of saying that we cannot act thus. For, in this case, the idea of duty falls to the ground of itself; “ultra posse nemo obligatur.” Hence there can be no quarrel between politics, as the practical science of right, and morals, which is also a science of right, but theoretical. That is, theory cannot come into conflict with practice. For, in that case, we would need to understand under the term “ethics” or “morals” a universal doctrine of expediency, or, in other words, a theory of precepts which may guide us in choosing the best means for attaining ends calculated for our advantage. This is to deny that a science of morals exists.

[p. 162]

Politics says, “Be wise as serpents”; morals adds the limiting condition, “and guileless as doves.” If these precepts cannot stand together in one command, then there is a real quarrel between politics and morals.[147] But if they can be completely brought into accord, then the idea of any antagonism between them is absurd, and the question of how best to make a compromise between the two points of view ceases to be even raised. Although the saying, “Honesty is the best policy, [p. 163] ” expresses a theory which, alas, is often contradicted in practice, yet the likewise theoretical maxim, “Honesty is better than any policy,” is exalted high above every possible objection, is indeed the necessary condition of all politics.

The Terminus of morals does not yield to Jupiter, the Terminus of force; for the latter remains beneath the sway of Fate. In other words, reason is not sufficiently enlightened to survey the series of predetermining causes which would make it possible for us to predict with certainty the good or bad results of human action, as they follow from the mechanical laws of nature; although we may hope that things will turn out as we should desire. But what we have to do, in order to remain in the path of duty guided by the rules of wisdom, reason makes everywhere perfectly clear, and does this for the purpose of furthering her ultimate ends.

The practical man, however, for whom morals is mere theory, even while admitting that what ought to be can be, bases his dreary verdict against our well-meant hopes really on this: he pretends that he can foresee from his observation of human nature, that men will never be willing to do what is required in order to bring about the wished-for results leading to perpetual peace. It is true that the will of all individual men to live under a legal constitution according to the principles of liberty [p. 164] —that is to say, the distributive unity of the wills of all—is not sufficient to attain this end. We must have the collective unity of their united will: all as a body must determine these new conditions. The solution of this difficult problem is required in order that civil society should be a whole. To all this diversity of individual wills there must come a uniting cause, in order to produce a common will which no distributive will is able to give. Hence, in the practical realisation of that idea, no other beginning of a law-governed society can be counted upon than one that is brought about by force: upon this force, too, public law afterwards rests. This state of things certainly prepares us to meet considerable deviation in actual experience from the theoretical idea of perpetual peace, since we cannot take into account the moral character and disposition of a law-giver in this connection, or expect that, after he has united a wild multitude into one people, he will leave it to them to bring about a legal constitution by their common will.

It amounts to this. Any ruler who has once got the power in his hands will not let the people dictate laws for him. A state which enjoys an independence of the control of external law will not submit to the judgment of the tribunals of other states, when it has to consider how to obtain [p. 165] its rights against them. And even a continent, when it feels its superiority to another, whether this be in its way or not, will not fail to take advantage of an opportunity offered of strengthening its power by the spoliation or even conquest of this territory. Hence all theoretical schemes, connected with constitutional, international or cosmopolitan law, crumble away into empty impracticable ideals. While, on the other hand, a practical science, based on the empirical principles of human nature, which does not disdain to model its maxims on an observation of actual life, can alone hope to find a sure foundation on which to build up a system of national policy.

Now certainly, if there is neither freedom nor a moral law founded upon it, and every actual or possible event happens in the mere mechanical course of nature, then politics, as the art of making use of this physical necessity in things for the government of men, is the whole of practical wisdom and the idea of right is an empty concept. If, on the other hand, we find that this idea of right is necessarily to be conjoined with politics and even to be raised to the position of a limiting condition of that science, then the possibility of reconciling them must be admitted. I can thus imagine a moral politician, that is to say, one who understands the principles of statesmanship to be such as do not [p. 166] conflict with morals; but I cannot conceive of a political moralist who fashions for himself such a system of ethics as may serve the interest of statesmen.

The moral politician will always act upon the following principle:—“If certain defects which could not have been avoided are found in the political constitution or foreign relations of a state, it is a duty for all, especially for the rulers of the state, to apply their whole energy to correcting them as soon as possible, and to bringing the constitution and political relations on these points into conformity with the Law of Nature, as it is held up as a model before us in the idea of reason; and this they should do even at a sacrifice of their own interest.” Now it is contrary to all politics—which is, in this particular, in agreement with morals—to dissever any of the links binding citizens together in the state or nations in cosmopolitan union, before a better constitution is there to take the place of what has been thus destroyed. And hence it would be absurd indeed to demand that every imperfection in political matters must be violently altered on the spot. But, at the same time, it may be required of a ruler at least that he should earnestly keep the maxim in mind which points to the necessity of such a change; so that he may go on constantly approaching the end to be realised, [p. 167] namely, the best possible constitution according to the laws of right. Even although it is still under despotic rule, in accordance with its constitution as then existing, a state may govern itself on republican lines, until the people gradually become capable of being influenced by the mere idea of the authority of law, just as if it had physical power. And they become accordingly capable of self-legislation, their faculty for which is founded on original right. But if, through the violence of revolution, the product of a bad government, a constitution more in accord with the spirit of law were attained even by unlawful means, it should no longer be held justifiable to bring the people back to the old constitution, although, while the revolution was going on, every one who took part in it by use of force or stratagem, may have been justly punished as a rebel. As regards the external relations of nations, a state cannot be asked to give up its constitution, even although that be a despotism (which is, at the same time, the strongest constitution where foreign enemies are concerned), so long as it runs the risk of being immediately swallowed up by other states. Hence, when such a proposal is made, the state whose constitution is in question must at least be allowed to defer acting upon it until a more convenient time.[148]

[p. 168]

It is always possible that moralists who rule despotically, and are at a loss in practical matters, will come into collision with the rules of political wisdom in many ways, by adopting measures without sufficient deliberation which show themselves afterwards to have been overestimated. When they thus offend against nature, experience must gradually lead them into a better track. But, instead of this being the case, politicians who are fond of moralising do all they can to make moral improvement impossible and to perpetuate violations of law, by extenuating political principles which are antagonistic to the idea of right, on the pretext that human nature is not capable of good, in the sense of the ideal which reason prescribes.

These politicians, instead of adopting an open, straightforward way of doing things (as they boast), mix themselves up in intrigue. They get at the [p. 169] authorities in power and say what will please them; their sole bent is to sacrifice the nation, or even, if they can, the whole world, with the one end in view that their own private interest may be forwarded. This is the manner of regular jurists (I mean the journeyman lawyer not the legislator), when they aspire to politics. For, as it is not their business to reason too nicely over legislation, but only to enforce the laws of the country, every legal constitution in its existing form and, when this is changed by the proper authorities, the one which takes its place, will always seem to them the best possible. And the consequence is that everything is purely mechanical. But this adroitness in suiting themselves to any circumstances may lead them to the delusion that they are also capable of giving an opinion about the principles of political constitutions in general, in so far as they conform to ideas of right, and are therefore not empirical, but a priori. And they may therefore brag about their knowledge of men,—which indeed one expects to find, since they have to deal with so many—without really knowing the nature of man and what can be made of it, to gain which knowledge a higher standpoint of anthropological observation than theirs is required. Filled with ideas of this kind, if they trespass outside their own sphere on the boundaries of political and international law, [p. 170] looked upon as ideals which reason holds before us, they can do so only in the spirit of chicanery. For they will follow their usual method of making everything conform mechanically to compulsory laws despotically made and enforced, even here, where the ideas of reason recognise the validity of a legal compulsory force, only when it is in accordance with the principles of freedom through which a permanently valid constitution becomes first of all possible. The would-be practical man, leaving out of account this idea of reason, thinks that he can solve this problem empirically by looking to the way in which those constitutions which have best survived the test of time were established, even although the spirit of these may have been generally contrary to the idea of right. The principles which he makes use of here, although indeed he does not make them public, amount pretty much to the following sophistical maxims.

1. Fac et excusa. Seize the most favourable opportunity for arbitrary usurpation—either of the authority of the state over its own people or over a neighbouring people; the justification of the act and extenuation of the use of force will come much more easily and gracefully, when the deed is done, than if one has to think out convincing reasons for taking this step and first hear through all the objections which can be made against it. This is [p. 171] especially true in the first case mentioned, where the supreme power in the state also controls the legislature which we must obey without any reasoning about it. Besides, this show of audacity in a statesman even lends him a certain semblance of inward conviction of the justice of his action; and once he has got so far the god of success (bonus eventus) is his best advocate.

2. Si fecisti, nega. As for any crime you have committed, such as has, for instance, brought your people to despair and thence to insurrection, deny that it has happened owing to any fault of yours. Say rather that it is all caused by the insubordination of your subjects, or, in the case of your having usurped a neighbouring state, that human nature is to blame; for, if a man is not ready to use force and steal a march upon his neighbour, he may certainly count on the latter forestalling him and taking him prisoner.

3. Divide et impera. That is to say, if there are certain privileged persons, holding authority among the people, who have merely chosen you for their sovereign as primus inter pares, bring about a quarrel among them, and make mischief between them and the people. Now back up the people with a dazzling promise of greater freedom; everything will now depend unconditionally on your will. Or again, if there is a difficulty with [p. 172] foreign states, then to stir up dissension among them is a pretty sure means of subjecting first one and then the other to your sway, under the pretext of aiding the weaker.

It is true that now-a-days no body is taken in by these political maxims, for they are all familiar to everyone. Moreover, there is no need of being ashamed of them, as if their injustice were too patent. For the great Powers never feel shame before the judgment of the common herd, but only before one another; so that as far as this matter goes, it is not the revelation of these guiding principles of policy that can make rulers ashamed, but only the unsuccessful use of them. For as to the morality of these maxims, politicians are all agreed. Hence there is always left political prestige on which they can safely count; and this means the glory of increasing their power by any means that offer.[149]

*   *   *

In all these twistings and turnings of an immoral doctrine of expediency which aims at substituting a state of peace for the warlike conditions in which men are placed by nature, so much at least is clear;—that men cannot get away from [p. 173] the idea of right in their private any more than in their public relations; and that they do not dare (this is indeed most strikingly seen in the concept of an international law) to base politics [p. 174] merely on the manipulations of expediency and therefore to refuse all obedience to the idea of a public right. On the contrary, they pay all fitting honour to the idea of right in itself, even although they should, at the same time, devise a hundred subterfuges and excuses to avoid it in practice, and should regard force, backed up by cunning, as having the authority which comes from being the source and unifying principle of all right. It will be well to put an end to this sophistry, if not to the injustice it extenuates, and to bring the false advocates of the mighty of the earth to confess that it is not right but might in whose interest they speak, and that it is the worship of might from which they take their cue, as if in this matter they had a right to command. In order to do this, we must first expose the delusion by which they deceive them [p. 175] selves and others; then discover the ultimate principle from which their plans for a perpetual peace proceed; and thence show that all the evil which stands in the way of the realisation of that ideal springs from the fact that the political moralist begins where the moral politician rightly ends and that, by subordinating principles to an end or putting the cart before the horse, he defeats his intention of bringing politics into harmony with morals.

In order to make practical philosophy consistent with itself, we must first decide the following question:—In dealing with the problems of practical reason must we begin from its material principle—the end as the object of free choice—or from its formal principle which is based merely on freedom in its external relation?—from which comes the following law:—“Act so that thou canst will that thy maxim should be a universal law, be the end of thy action what it will.”[150]

Without doubt, the latter determining principle of action must stand first; for, as a principle of right, it carries unconditional necessity with it, whereas the former is obligatory only if we assume the empirical conditions of the end set before us,—that is to say, that it is an end capable of being [p. 176] practically realised. And if this end—as, for example, the end of perpetual peace—should be also a duty, this same duty must necessarily have been deduced from the formal principle governing the maxims which guide external action. Now the first principle is the principle of the political moralist; the problems of constitutional, international and cosmopolitan law are mere technical problems (problema technicum). The second or formal principle, on the other hand, as the principle of the moral politician who regards it as a moral problem (problema morale), differs widely from the other principle in its methods of bringing about perpetual peace, which we desire not only as a material good, but also as a state of things resulting from our recognition of the precepts of duty.[151]

To solve the first problem—that, namely, of political expediency—much knowledge of nature is required, that her mechanical laws may be employed for the end in view. And yet the result of all knowledge of this kind is uncertain, as far as perpetual peace is concerned. This we find to be so, whichever of the three departments of public law we take. It is uncertain whether a people could be better kept in obedience and at the same time prosperity by severity or by baits held out to their [p. 177] vanity; whether they would be better governed under the sovereignty of a single individual or by the authority of several acting together; whether the combined authority might be better secured merely, say, by an official nobility or by the power of the people within the state; and, finally, whether such conditions could be long maintained. There are examples to the contrary in history in the case of all forms of government, with the exception of the only true republican constitution, the idea of which can occur only to a moral politician. Still more uncertain is a law of nations, ostensibly established upon statutes devised by ministers; for this amounts in fact to mere empty words, and rests on treaties which, in the very act of ratification, contain a secret reservation of the right to violate them. On the other hand, the solution of the second problem—the problem of political wisdom—forces itself, we may say, upon us; it is quite obvious to every one, and puts all crooked dealings to shame; it leads, too, straight to the desired end, while at the same time, discretion warns us not to drag in the conditions of perpetual peace by force, but to take time and approach this ideal gradually as favourable circumstances permit.

This may be expressed in the following maxim:—“Seek ye first the kingdom of pure practical reason and its righteousness, and the object of your en [p. 178] deavour, the blessing of perpetual peace, will be added unto you.” For the science of morals generally has this peculiarity,—and it has it also with regard to the moral principles of public law, and therefore with regard to a science of politics knowable a priori,—that the less it makes a man’s conduct depend on the end he has set before him, his purposed material or moral gain, so much the more, nevertheless, does it conform in general to this end. The reason for this is that it is just the universal will, given a priori, which exists in a people or in the relation of different peoples to one another, that alone determines what is lawful among men. This union of individual wills, however, if we proceed consistently in practice, in observance of the mechanical laws of nature, may be at the same time the cause of bringing about the result intended and practically realizing the idea of right. Hence it is, for example, a principle of moral politics that a people should unite into a state according to the only valid concepts of right, the ideas of freedom and equality; and this principle is not based on expediency, but upon duty. Political moralists, however, do not deserve a hearing, much and sophistically as they may reason about the existence, in a multitude of men forming a society, of certain natural tendencies which would weaken those principles and defeat their intention. They [p. 179] may endeavour to prove their assertion by giving instances of badly organised constitutions, chosen both from ancient and modern times, (as, for example, democracies without a representative system); but such arguments are to be treated with contempt, all the more, because a pernicious theory of this kind may perhaps even bring about the evil which it prophesies. For, in accordance with such reasoning, man is thrown into a class with all other living machines which only require the consciousness that they are not free creatures to make them in their own judgment the most miserable of all beings.

Fiat justitia, pereat mundus. This saying has become proverbial, and although it savours a little of boastfulness, is also true. We may translate it thus:—“Let justice rule on earth, although all the rogues in the world should go to the bottom.” It is a good, honest principle of right cutting off all the crooked ways made by knavery or violence. It must not, however, be misunderstood as allowing anyone to exercise his own rights with the utmost severity, a course in contradiction to our moral duty; but we must take it to signify an obligation, binding upon rulers, to refrain from refusing to yield anyone his rights or from curtailing them, out of personal feeling or sympathy for others. For this end, in particular, we require, firstly, that a state [p. 180] should have an internal political constitution, established according to the pure principles of right; secondly, that a union should be formed between this state and neighbouring or distant nations for a legal settlement of their differences, after the analogy of the universal state. This proposition means nothing more than this:—Political maxims must not start from the idea of a prosperity and happiness which are to be expected from observance of such precepts in every state; that is, not from the end which each nation makes the object of its will as the highest empirical principle of political wisdom; but they must set out from the pure concept of the duty of right, from the “ought” whose principle is given a priori through pure reason. This is the law, whatever the material consequences may be. The world will certainly not perish by any means, because the number of wicked people in it is becoming fewer. The morally bad has one peculiarity, inseparable from its nature;—in its purposes, especially in relation to other evil influences, it is in contradiction with itself, and counteracts its own natural effect, and thus makes room for the moral principle of good, although advance in this direction may be slow.

Hence objectively, in theory, there is no quarrel between morals and politics. But subjectively, in the self-seeking tendencies of men (which we cannot [p. 181] actually call their morality, as we would a course of action based on maxims of reason,) this disagreement in principle exists and may always survive; for it serves as a whetstone to virtue. According to the principle, Tu ne cede malis, sed contra audentior ito, the true courage of virtue in the present case lies not so much in facing the evils and self-sacrifices which must be met here as in firmly confronting the evil principle in our own nature and conquering its wiles. For this is a principle far more dangerous, false, treacherous and sophistical which puts forward the weakness in human nature as a justification for every transgression.

In fact the political moralist may say that a ruler and people, or nation and nation do one another no wrong, when they enter on a war with violence or cunning, although they do wrong, generally speaking, in refusing to respect the idea of right which alone could establish peace for all time. For, as both are equally wrongly disposed to one another, each transgressing the duty he owes to his neighbour, they are both quite rightly served, when they are thus destroyed in war. This mutual destruction stops short at the point of extermination, so that there are always enough of the race left to keep this game going on through all the ages, and a far-off posterity may take warning [p. 182] by them. The Providence that orders the course of the world is hereby justified. For the moral principle in mankind never becomes extinguished, and human reason, fitted for the practical realisation of ideas of right according to that principle, grows continually in fitness for that purpose with the ever advancing march of culture; while at the same time, it must be said, the guilt of transgression increases as well. But it seems that, by no theodicy or vindication of the justice of God, can we justify Creation in putting such a race of corrupt creatures into the world at all, if, that is, we assume that the human race neither will nor can ever be in a happier condition than it is now. This standpoint, however, is too high a one for us to judge from, or to theorise, with the limited concepts we have at our command, about the wisdom of that supreme Power which is unknowable by us. We are inevitably driven to such despairing conclusions as these, if we do not admit that the pure principles of right have objective reality—that is to say, are capable of being practically realised—and consequently that action must be taken on the part of the people of a state and, further, by states in relation to one another, whatever arguments empirical politics may bring forward against this course. Politics in the real sense cannot take a step forward without first paying homage [p. 183] to the principles of morals. And, although politics, per se, is a difficult art,[152] in its union with morals no art is required; for in the case of a conflict arising between the two sciences, the moralist can cut asunder the knot which politics is unable to untie. Right must be held sacred by man, however great the cost and sacrifice to the ruling power. Here is no half-and-half course. We cannot devise a happy medium between right and expediency, a right pragmatically conditioned. But all politics must bend the knee to the principle of right, and may, in that way, hope to reach, although slowly perhaps, a level whence it may shine upon men for all time.

[p. 184]

APPENDIX II. CONCERNING THE HARMONY OF POLITICS WITH MORALS ACCORDING TO THE TRANSCENDENTAL IDEA OF PUBLIC RIGHT↩

If I look at public right from the point of view of most professors of law, and abstract from its matter or its empirical elements, varying according to the circumstances given in our experience of individuals in a state or of states among themselves, then there remains the form of publicity. The possibility of this publicity, every legal title implies. For without it there could be no justice, which can only be thought as before the eyes of men; and, without justice, there would be no right, for, from justice only, right can come.

This characteristic of publicity must belong to every legal title. Hence, as, in any particular case that occurs, there is no difficulty in deciding whether this essential attribute is present or not, (whether, that is, it is reconcilable with the principles of the agent or not), it furnishes an easily applied criterion [p. 185] which is to be found a priori in the reason, so that in the particular case we can at once recognise the falsity or illegality of a proposed claim (praetensio juris), as it were by an experiment of pure reason.

Having thus, as it were, abstracted from all the empirical elements contained in the concept of a political and international law, such as, for instance, the evil tendency in human nature which makes compulsion necessary, we may give the following proposition as the transcendental formula of public right:—“All actions relating to the rights of other men are wrong, if the maxims from which they follow are inconsistent with publicity.”

This principle must be regarded not merely as ethical, as belonging to the doctrine of virtue, but also as juridical, referring to the rights of men. For there is something wrong in a maxim of conduct which I cannot divulge without at once defeating my purpose, a maxim which must therefore be kept secret, if it is to succeed, and which I could not publicly acknowledge without infallibly stirring up the opposition of everyone. This necessary and universal resistance with which everyone meets me, a resistance therefore evident a priori, can be due to no other cause than the injustice with which such a maxim threatens everyone. Further, this testing principle is merely negative; that is, it serves only as a means by which we may know [p. 186] when an action is unjust to others. Like axioms, it has a certainty incapable of demonstration; it is besides easy of application as appears from the following examples of public right.

1.—Constitutional Law. Let us take in the first place the public law of the state (jus civitatis), particularly in its application to matters within the state. Here a question arises which many think difficult to answer, but which the transcendental principle of publicity solves quite readily:—“Is revolution a legitimate means for a people to adopt, for the purpose of throwing off the oppressive yoke of a so-called tyrant (non titulo, sed exercitio talis)?” The rights of a nation are violated in a government of this kind, and no wrong is done to the tyrant in dethroning him. Of this there is no doubt. None the less, it is in the highest degree wrong of the subjects to prosecute their rights in this way; and they would be just as little justified in complaining, if they happened to be defeated in their attempt and had to endure the severest punishment in consequence.

A great many reasons for and against both sides of this question may be given, if we seek to settle it by a dogmatic deduction of the principles of right. But the transcendental principle of the publicity of public right can spare itself this diffuse argumentation. For, according to that principle, the [p. 187] people would ask themselves, before the civil contract was made, whether they could venture to publish maxims, proposing insurrection when a favourable opportunity should present itself. It is quite clear that if, when a constitution is established, it were made a condition that force may be exercised against the sovereign under certain circumstances, the people would be obliged to claim a lawful authority higher than his. But in that case, the so-called sovereign would be no longer sovereign: or, if both powers, that of the sovereign and that of the people, were made a condition of the constitution of the state, then its establishment (which was the aim of the people) would be impossible. The wrongfulness of revolution is quite obvious from the fact that openly to acknowledge maxims which justify this step would make attainment of the end at which they aim impossible. We are obliged to keep them secret. But this secrecy would not be necessary on the part of the head of the state. He may say quite plainly that the ringleaders of every rebellion will be punished by death, even although they may hold that it was he who first transgressed the fundamental law. For, if a ruler is conscious of possessing irresistible sovereign power (and this must be assumed in every civil constitution, because a sovereign who has not power to protect any individual member [p. 188] of the nation against his neighbour has also not the right to exercise authority over him), then he need have no fear that making known the maxims which guide him will cause the defeat of his plans. And it is quite consistent with this view to hold that, if the people are successful in their insurrection, the sovereign must return to the rank of a subject, and refrain from inciting rebellion with a view to regaining his lost sovereignty. At the same time he need have no fear of being called to account for his former administration.[153]

[p. 189]

2.—International Law. There can be no question of an international law, except on the assumption of some kind of a law-governed state of things, the external condition under which any right can belong to man. For the very idea of international law, as public right, implies the publication of a universal will determining the rights and property of each individual nation; and this status juridicus must spring out of a contract of some sort which may not, like the contract to which the state owes its origin, be founded upon compulsory laws, but may be, at the most, the agreement of a permanent free association such as the federation of the different states, to which we have alluded above. For, without the control of law to some extent, to serve as an active bond of union among different merely natural or moral individuals,—that is to say, in a state of nature,—there can only be private law. And here we find a disagreement between morals, regarded as the science of right, and politics. The criterion, obtained by observing the effect of publicity on maxims, is just as easily applied, but only when we understand that this agreement binds the contracting states solely with the object that peace may be preserved among them, and between them and other states; in no sense with a view to the acquisition of new territory or power. The following instances of antinomy occur between [p. 190] politics and morals, which are given here with the solution in each case.

a. “When either of these states has promised something to another, (as, for instance, assistance, or a relinquishment of certain territory, or subsidies and such like), the question may arise whether, in a case where the safety of the state thus bound depends on its evading the fulfilment of this promise, it can do so by maintaining a right to be regarded as a double person:—firstly, as sovereign and accountable to no one in the state of which that sovereign power is head; and, secondly, merely as the highest official in the service of that state, who is obliged to answer to the state for every action. And the result of this is that the state is acquitted in its second capacity of any obligation to which it has committed itself in the first.” But, if a nation or its sovereign proclaimed these maxims, the natural consequence would be that every other would flee from it, or unite with other states to oppose such pretensions. And this is a proof that politics, with all its cunning, defeats its own ends, if the test of making principles of action public, which we have indicated, be applied. Hence the maxim we have quoted must be wrong.

b. “If a state which has increased its power to a formidable extent (potentia tremenda) excites anxiety in its neighbours, is it right to assume [p. 191] that, since it has the means, it will also have the will to oppress others; and does that give less powerful states a right to unite and attack the greater nation without any definite cause of offence?” A state which would here answer openly in the affirmative would only bring the evil about more surely and speedily. For the greater power would forestall those smaller nations, and their union would be but a weak reed of defence against a state which knew how to apply the maxim, divide et impera. This maxim of political expediency then, when openly acknowledged, necessarily defeats the end at which it aims, and is therefore wrong.

c. “If a smaller state by its geographical position breaks up the territory of a greater, so as to prevent a unity necessary to the preservation of that state, is the latter not justified in subjugating its less powerful neighbour and uniting the territory in question with its own?” We can easily see that the greater state dare not publish such a maxim beforehand; for either all smaller states would without loss of time unite against it, or other powers would contend for this booty. Hence the impracticability of such a maxim becomes evident under the light of publicity. And this is a sign that it is wrong, and that in a very great degree; for, although the victim of an act of injustice may be [p. 192] of small account, that does not prevent the injustice done from being very great.

3.—Cosmopolitan Law. We may pass over this department of right in silence, for, owing to its analogy with international law, its maxims are easily specified and estimated.

*   *   *

In this principle of the incompatibility of the maxims of international law with their publicity, we have a good indication of the non-agreement between politics and morals, regarded as a science of right. Now we require to know under what conditions these maxims do agree with the law of nations. For we cannot conclude that the converse holds, and that all maxims which can bear publicity are therefore just. For anyone who has a decided supremacy has no need to make any secret about his maxims. The condition of a law of nations being possible at all is that, in the first place, there should be a law-governed state of things. If this is not so, there can be no public right, and all right which we can think of outside the law-governed state,—that is to say, in the state of nature,—is mere private right. Now we have seen [p. 193] above that something of the nature of a federation between nations, for the sole purpose of doing away with war, is the only rightful condition of things reconcilable with their individual freedom. Hence the agreement of politics and morals is only possible in a federative union, a union which is necessarily given a priori, according to the principles of right. And the lawful basis of all politics can only be the establishment of this union in its widest possible extent. Apart from this end, all political sophistry is folly and veiled injustice. Now this sham politics has a casuistry, not to be excelled in the best Jesuit school. It has its mental reservation (reservatio mentalis): as in the drawing up of a public treaty in such terms as we can, if we will, interpret when occasion serves to our advantage; for example, the distinction between the status quo in fact (de fait) and in right (de droit). Secondly, it has its probabilism; when it pretends to discover evil intentions in another, or makes, the probability of their possible future ascendency a lawful reason for bringing about the destruction of other peaceful states. Finally, it has its philosophical sin (peccatum philosophicum, peccatillum, baggatelle) which is that of holding it a trifle easily pardoned that a smaller state should be swallowed up, if this be to the gain of a nation much more powerful; for such an increase in power is [p. 194] supposed to tend to the greater prosperity of the whole world.[154]

Duplicity gives politics the advantage of using one branch or the other of morals, just as suits its own ends. The love of our fellowmen is a duty: so too is respect for their rights. But the former is only conditional: the latter, on the other hand, an unconditional, absolutely imperative duty; and anyone who would give himself up to the sweet consciousness of well-doing must be first perfectly assured that he has not transgressed its commands. Politics has no difficulty in agreeing with morals in the first sense of the term, as ethics, to secure that men should give to superiors their rights. But when it comes to morals, in its second aspect, as the science of right before which politics must bow the knee, the politician finds it prudent to have nothing to do with compacts and rather to deny all reality to morals in this sense, and reduce all duty to mere benevolence. Philosophy could easily frustrate the artifices of a politics like [p. 195] this, which shuns the light of criticism, by publishing its maxims, if only statesmen would have the courage to grant philosophers the right to ventilate their opinions.

With this end in view, I propose another principle of public right, which is at once transcendental and affirmative. Its formula would be as follows:—“All maxims which require publicity, in order that they may not fail to attain their end, are in agreement both with right and politics.”

For, if these maxims can only attain the end at which they aim by being published, they must be in harmony with the universal end of mankind, which is happiness; and to be in sympathy with this (to make the people contented with their lot) is the real business of politics. Now, if this end should be attainable only by publicity, or in other words, through the removal of all distrust of the maxims of politics, these must be in harmony with the right of the people; for a union of the ends of all is only possible in a harmony with this right.

I must postpone the further development and discussion of this principle till another opportunity. That it is a transcendental formula is quite evident from the fact that all the empirical conditions of a doctrine of happiness, or the matter of law, are absent, and that it has regard only to the form of universal conformity to law.

[p. 196] *   *   *

If it is our duty to realise a state of public right, if at the same time there are good grounds for hope that this ideal may be realised, although only by an approximation advancing ad infinitum, then perpetual peace, following hitherto falsely so-called conclusions of peace, which have been in reality mere cessations of hostilities, is no mere empty idea. But rather we have here a problem which gradually works out its own solution and, as the periods in which a given advance takes place towards the realisation of the ideal of perpetual peace will, we hope, become with the passing of time shorter and shorter, we must approach ever nearer to this goal.
