Arbitration has from the earliest times been preferred in most of those cases to which it was applicable, that is, in cases in which there was a basis of common view or common tradition sufficient to make agreement practicable. But wherever there has been a marked divergence of ideals or a different standard of right, there has been a tendency for each side to feel that to submit its conscience or its convictions of right, its sense of what is most sacred in life, to an outside judgment would involve a kind of moral suicide. In such cases every nation repudiates arbitration and prefers to be a martyr, in case of need, to its sense of justice. It is at least an open question whether the disappearance of this feeling would be a mark of progress or of degeneration. At any rate it is practically certain that the period when it will have disappeared cannot at present be foreseen. The abolition of war, therefore, involves the abolition of independent States and their amalgamation into one. There are many who have hoped for this ideal, expressed by Tennyson when he dreamed of "The Parliament of man, the Federation of the world." That it is the ultimate destiny of mankind to be united under a single Government seems probable enough, but it is rash to assume that that result will be reached either by a process of peaceful negotiation, or by the spread of the imperfect methods of modern democratic government. The German Empire, with its population of sixty millions, educated by the State, disciplined by the State, relying on the State, and commanded by the State, is as potent in comparison with the less disciplined and less organised communities which surround it as was, in the third century before Christ, the Roman State in comparison with the disunited multitude of Greek cities, the commercial oligarchy of Carthage, and the half-civilised tribes of Gaul and Spain. Unless the other States of Europe can rouse themselves to a discipline as sound and to an organisation as subtle as those of Prussia and to the perception of a common purpose in the maintenance of their independence, the union of Europe under a single Government is more likely to be brought about by the conquering hand of Germany than by the extension of democratic institutions and of sentimental good understandings.
