“ It is a well-known fact that a distinction has to be made between universal International Law, that is, rules to which every civilised State agrees, and general International Law, that is, rules to which only the greater number of States agree. Now it is quite certain that no universal International Law can be created by legislation to which not every member of the League of Nations has agreed. ”

“ Who will keep in order those who are to keep the world in order? A League of Nations which can only be kept together by a powerful International Army and Navy, is a contradiction in itself; for the independence and equality of the member States of the League would soon disappear. It is a fact—I make this statement although I am sure it will be violently contradicted—that, just as hitherto, so within a League of Nations some kind of Balance of Power only can guarantee the independence and equality of the smaller States. ”

“ It would therefore seem to be certain that, while the memory of these losses in lives and wealth lasts, all the members of the League will faithfully carry out the obligations connected with the membership of the League into which they enter for the purpose of avoiding such a disaster as, like a bolt from the blue, fell upon mankind by the outbreak of the present war. On the other hand, I will not deny that no one can guarantee the future; that conflicts may arise which will shake the foundations of the League of Nations; that the League may fall to pieces ”

“ The Great Powers are the leaders of the Family of Nations because their political influence [31] is so great. Their political and economic influence is in the long run irresistible; therefore all arrangements made by the Great Powers naturally in most cases gain, either at once or in time, the consent of the minor States. It may be said that the Great Powers exercise a kind of political hegemony within the Family of Nations. Yet this hegemony is not based on law, it is simply a political fact, and it is certainly not a consequence of an organisation of the Family of Nations. ”

“ The universal demand for a new League of Nations accepting the principles that every judicial dispute amongst nations must be settled by International Courts and that every political dispute must, before the parties resort to arms, be brought before a Council of Conciliation, demonstrates clearly that the Community of States must now deliberately give itself some kind of organisation, because without it the principles just mentioned cannot be realised. ”

“ And even if it were otherwise, if the entrance of a State into the new League of Nations did involve an infringement of its sovereignty and independence, humanity need not grieve over it. The Prussian conception of the State as an end in itself and of the authority of the State as something above everything else and divine—a conception which found support in the philosophy of Hegel and his followers—is adverse to the ideal of democracy and constitutional government. ”

“ The sovereignty of a monarch, or of a Parliament, or of the whole people is not an original attribute of their own, but derives from the sovereignty of the State which is governed by them. It is outside the scope of this lecture to give you a history of the conception of sovereignty, it suffices to state the undeniable fact that from the time when the term was first introduced into political science until the present day there has never been unanimity with regard to its meaning, except that it is a synonym for independence of all earthly authority. ”

“ History in most cases takes no leaps, but if exceptionally History does take a leap, there is great danger of a bad slip backwards following. We must be on our guard lest the proposed League of Nations should take a leap in the dark, and the realisation of proposals be attempted which are so daring and so entirely out of keeping with the historical development of International Law and the growth of the Society of Nations, that there would be great danger of the whole scheme collapsing and the whole movement coming to naught. ”

“ The mere fact that there is an International Law in existence restricts the unbounded liberty of action of every civilised State, because every State is prohibited from interfering with the affairs of every other State. The fact is that the independence of every State finds its limitation in the independence of every [78] other State. And it is generally admitted that a State can through conventions—such as a treaty of alliance or of neutrality or others—enter into many obligations which more or less restrict its liberty of action. ”

“ Everything depends upon what principles will guide the States in their selection of the individuals whom they appoint as members of International Courts. Not diplomatists, not politicians, but only men ought to be appointed who have had a training in law in general, and in International Law in particular; men who are linguists, knowing, at any rate, the French language besides their own; men who possess independence of character and are free from national prejudices of every kind. ”

“ But the progress of International Law is conditioned by the growth, the strengthening, and the deepening of international economic and other interests, and of international morality. It is a matter of course that this progress can only be realised very slowly, for there is concerned a process of development through many generations and perhaps through centuries, a development [34] whose end no one can foresee. It is sufficient for us to state that the development had already begun before the World War, and to try to foster it, as far as is in our power, after the conclusion of peace. ”

“ The British World Empire may be taken as an example to show that it is impossible for one single central Government to govern a number of States with somewhat divergent interests. We all know that the British Empire comprising the United Kingdom and the so-called independent dominions, namely Canada, Newfoundland, Australia, New Zealand, and South Africa, is kept together not really by the powers of the British Government but by the good will of the component parts. ”

“ Constitutional Government within the several States has to grapple with many difficulties, and these difficulties would be more numerous, greater, and much more complicated within a Federal World State. We need democracy and constitutional Government in every single State, and this can only be realised by party Government and elections of Parliament at short intervals. The waves of party strife rise high within the several States; no sooner is one party in, than the other party looks out for an opening into which a wedge can be pushed to turn the Government out. ”

“ I have only named three aims and four problems because I have in my mind those aims which are the nearest and those problems which are the most pressing and the most urgent. The range of vision of the League of Nations, when once established, will no doubt gradually become wider and wider; new aims will arise and new problems will demand solution, but all such possible future aims and future problems are outside the scope of these lectures. ”

“ Whereas the family, the tribe, and the race are natural products, the nation as well as the State are products of historical development. All nations are blends of more or less different races, and all States were originally founded on force: strong rulers subjected neighbouring tribes and peoples to their sway and thus formed coherent nations. Most of the States in Europe are the product of the activity of strong dynasties which through war and conquest, and through marriage and purchase, united under one sovereign the lands which form the States and the peoples which form the nations. ”

“ Only between the several city States of ancient Greece arose some kind of what we should now call 'International Law,' because these city States formed a Community fostered by the same language, the same civilisation, the same religion, the same general ideas, and by constant commercial and other intercourse. On the other hand, the Roman Empire was a world empire, it gradually absorbed all the independent nations in the West. ”

“ States, of their constitutions, and many other difficulties, entail the danger that International Courts may become the arena of national jealousies, of empty talk, and of political intrigues, instead of being pillars of international justice. ”

“ A nation is a product of historical development, whereas a race is a product of natural growth. One speaks of a nation when a complex body of human beings is united by living in the same land, by the same language, the same literature, the same historical traditions, and the same general views of life. All nations are a mixture of several diverse racial elements which in the course of historical development have to a certain extent been united by force of circumstances. ”

“ Nevertheless, a League of Nations having once come into existence, International Law grew more and more, and when in 1625 Hugo Grotius published his immortal work on 'The Law of War and Peace,' the system of International Law offered in his work conquered the world and became the basis of all following development. ”

“ In our time it cannot be expected, and here therefore lies the great difficulty in the way of setting up and manning International Courts of Justice; because there is no doubt that each State will claim the right to appoint at least one man of its own choice to sit as judge in the International Court or Courts. And since there are about fifty or more civilised independent States in existence, the International Court would comprise fifty or more members. ”

“ In giving these lectures I propose to draw your attention, on the one hand, to the links which connect the proposal for a League of Nations with the past, and, on the other hand, to the difficulties with which the realisation of the proposal must necessarily be attended; and also to the ways in which, in my opinion, these difficulties can be overcome.
There is an old adage which says Natura non facit saltus, Nature takes no leaps. Everything in Nature develops gradually, step by step, and organically. ”

“ Internationalism had made great strides during the second part of the nineteenth century on account of the enormous development of international commerce and international communication favoured by railways, the steamship, the telegraph, and a great many scientific discoveries and technical inventions. But what a disturbing and destroying factor war really is, had not become fully apparent till the present war, because this is a world war which interferes almost as much with the welfare of neutrals as with the welfare of belligerents. ”

“ Therefore the Central Powers must become members of a League of Nations for such a League to be of any great use, which postulates as a sine qua non that Germany must be utterly defeated in the present war. ”

“ Under modern conditions of civilisation the whole world suffers in case war breaks out between even only two States, and for this reason it is advisable that the rest of the world should unite and oppose such State as would resort to arms without having submitted its case to an International Court of Justice or an International Council of Conciliation. ”

“ As International Statutes are only possible when the several States come to an agreement, it will often not be possible to legislate internationally on a given matter, because the interests of the different States will be so conflicting that an agreement cannot be arrived at. On the other hand, as time goes on the international interests of the several States frequently become so powerful that these Governments are quite ready to brush aside their particular interests, and to agree upon a compromise which makes International Legislation concerning the matter in question possible. ”
