Nevertheless the words have to be used, because there are no others which at all cover the facts. And, after all, they are in some ways entirely appropriate. A great part of the world's area is inhabited by peoples who are still in a condition of barbarism, and seem to have rested in that condition for untold centuries. For such peoples the only chance of improvement was that they should pass under the dominion of more highly developed peoples; and to them a European 'Empire' brought, for the first time, not merely law and justice, but even the rudiments of the only kind of liberty which is worth having, the liberty which rests upon law. Another vast section of the world's population consists of peoples who have in some respects reached a high stage of civilisation, but who have failed to achieve for themselves a mode of organisation which could give them secure order and equal laws. For such peoples also the 'Empire' of Western civilisation, even when it is imposed and maintained by force, may bring advantages which will far outweigh its defects. In these cases the word 'Empire' can be used without violence to its original significance, and yet without apology; and these cases cover by far the greater part of the world. The words 'Empire' and 'Imperialism' come to us from ancient Rome; and the analogy between the conquering and organising work of Rome and the empire-building work of the modern nation-states is a suggestive and stimulating analogy. The imperialism of Rome extended the modes of a single civilisation, and the Reign of Law which was its essence, over all the Mediterranean lands. The imperialism of the nations to which the torch of Rome has been handed on, has made the Reign of Law, and the modes of a single civilisation, the common possession of the whole world. Rome made the common life of Europe possible. The imperial expansion of the European nations has alone made possible the vision--nay, the certainty--of a future world-order. For these reasons we may rightly and without hesitation continue to employ these terms, provided that we remember always that the justification of any dominion imposed by a more advanced upon a backward or disorganised people is to be found, not in the extension of mere brute power, but in the enlargement and diffusion, under the shelter of power, of those vital elements in the life of Western civilisation which have been the secrets of its strength, and the greatest of its gifts to the world: the sovereignty of a just and rational system of law, liberty of person, of thought, and of speech, and, finally, where the conditions are favourable, the practice of self-government and the growth of that sentiment of common interest which we call the national spirit. These are the features of Western civilisation which have justified its conquest of the world[1]; and it must be for its success or failure in attaining these ends that we shall commend or condemn the imperial work
