Sc. 4. _War under Altered Conditions._ The Peace Societies of our century, untiring supporters of a point of view diametrically opposite 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. 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 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. [84] An admirable short account of popular feeling on this matter is to be found in Lawrence’s _Principles of International Law_, § 240. [85] The first Peace Society was founded in London in 1816, and the first International Peace Congress held in 1843. 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 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? [86] In Eng. trans. see p. 358. _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] 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. 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, 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 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. [87] See “A Plan for a Universal and Perpetual Peace” in the _Principles of International Law_ (_Works_, Vol. II). One of the main principles advocated by Bentham in this essay (written between 1787 and 1789) is that every state should give up its colonies. [88] See his _Kleine Schriften_. [89] _Institutes of the Law of Nations_ (1884), Vol. II., Ch. XIV. [90] John Stuart Mill holds that the multiplication of federal unions would be a benefit to the world. [See his _Considerations on Representative Government_ (1865), Ch. XVII., where he discusses the conditions necessary to render such unions successful.] But the Peace Society is scarcely justified, on the strength of what is here, in including Mill among writers who have made definite proposals of peace or federation. (See _Inter. Trib._) [91] See what Lawrence says (_op. cit._, § 241) of neutralisation and the limits of its usefulness as a remedy for war. [92] Montesquieu: _Esprit des Lois_, X. Ch. 2. “The life of governments is like that of man. The latter has a right to kill in case of natural defence: the former have a right to wage war for their own preservation.” See also Vattel (_Law of Nations_, II. Ch. XVIII. § 332):—“But if anyone would rob a nation of one of her essential rights, or a right without which she could not hope to support her national existence,—if an ambitious neighbour threatens the liberty of a republic, if he attempts to subjugate and enslave her,—she will take counsel only from her own courage. She will not even attempt the method of conferences, in the case of a contention so odious as this. She will, in such a quarrel, exert her utmost efforts, exhaust every resource and lavish her blood to the last drop if necessary. To listen to the slightest proposal in a matter of this kind is to risk everything.”
