The unity and nationhood of modern Germany is largely due to similar causes; and the war of 1871 may fairly be said to have led to a further integration of the national life of the French people, in spite of their defeat. America owes something of the same kind to the Spanish war; and the entry of that nation into the Great War, long delayed as it was, will probably be found to have had a similar effect. The French and Italian nations have undoubtedly been welded more firmly by the Great War; while England and her sister and daughter nations (with the one sad exception of the Irish) have been united, by their co-operation in the one great purpose, to a degree which no other conceivable event could have achieved and which many generations of peaceful industry and enlightened political efforts might have failed to approach.

History offers no parallel to these effects of war; and it is difficult or impossible to imagine any other common purpose which could exert this binding influence in a similar degree. But it is worth while to notice that other and minor forms of international rivalry have corresponding effects. The international rivalry in aeronautics affords a contemporary illustration. Perhaps every one in this country has felt some degree of interest and satisfaction in the achievements of the adventurous spirits of our nation who have traversed the Atlantic by air. And it is probably largely owing to the prevalence of this national pride and purpose that, at a time demanding strict national economy, no voice has been raised against the enormous current expenditure of the government upon aeronautics.

Another and more important effect of the same kind is produced by the assumption of great national responsibilities in the way of administration in respect of backward peoples and undeveloped territories. The greatest example in history is the responsibility of Great Britain for the administration of India, gradually and only half-consciously assumed, but now keenly felt as at once a legitimate ground of national pride and a moral responsibility that cannot be laid aside. It is like the responsibility of the father of a family in its semi-instinctive origin and in its effects in steadying and strengthening character, for it imposes a responsibility which the nation, like the individual, cannot discharge indifferently without seriously damaging its reputation and prestige in the eyes of the world. Holland owes some of the strength of her nationhood to such influences; and the assumption by the American nation of responsibility for the peoples of Cuba and of the Phillipine islands cannot fail to bring them in some degree similar moral benefits[77].

Of the five other conditions of the higher development of a collective mind, let us notice, first and very briefly, continuity of existence, material and formal. Of course every nation has this in some degree, but some have it in much higher degree than others. The English nation is fortunate in this respect also. It has preserved both its formal and its material continuity in very high degree throughout many centuries, in fact ever since the Norman Conquest. No European nation can compare with it in this respect; it is only surpassed by China and perhaps Japan. The French nation has preserved its material continuity, its population and territory, in high degree. But the Great Revolution cut across and destroyed to a great extent its formal continuity, so that, as is sometimes said, the French nation has cut itself off from its past and made a new start; although, in doing so, it did not get rid of its highly centralised system of administration. The modern Italian and German nations are quite recent growths, their formal continuity having been subject to many interruptions. Spain, with her almost insular position, might have had continuity; but it was greatly disturbed by the imperial ambitions of her rulers in the sixteenth century and by the expulsion of the Moors. Greece is a striking example of loss of both material and formal continuity. The population of ancient Greece, which put her in the van of civilisation, has been largely abolished and supplanted by a different race; and her formal continuity also has suffered a number of complete ruptures.

Now material and formal continuity is, as we said, the essential presupposition of all the other main conditions of development of the collective mind. On it depends the strength of custom and tradition and, to a very great extent, the strength of national sentiment. It is, therefore, a principal condition of national stability; from it arise all the great conservative tendencies of the nation, all the forces that resist change; accordingly, the more complete and long enduring such continuity has been in the past, the greater is the prospect of its prolongation in the future. It is owing to the unbroken continuity of the English nation through so long a period that its organisation is so stable, its unwritten constitution so effective, at once stable and plastic, its national sentiment so strong, its complex uncoded system of judge-made law so nearly in harmony with popular feeling and therefore so respected. National organisation resting upon this basis of custom and traditional sentiment is the only kind that is really stable, that is not liable to be suddenly overthrown by internal upheavals or impacts from without. For it alone is rooted in the minds of all citizens in the forms of habit and sentiment. All other organisation is imposed by authority.

In this respect modern England and Germany offer a striking contrast that forces itself upon the most casual observation. As regards the mass of the people, the position of each individual in the organism of the German nation is officially determined by the written and codified law of the State; all personal status and relations are formally determined by official positions in this recently created system. Almost every individual carries about some badge or uniform indicating his position within the system. In England, the status and relations of individuals are determined by factors a thousand times more subtle and complex, involving many vaguely conceived and undefined traditions and sentiments. In Germany, it is almost true to say, if a man has no official position he has no position at all. In England, the comparatively few persons who have official positions have also their social positions by which their private relations are determined. They are officials only in their offices; whereas the German official is an official everywhere.

Other important topics we have to consider are (1) the organisation of the national mind; (2) the national self-consciousness; (3) the interaction of the nation as a whole with other nations. All these we may advantageously consider in the light of an analogy, the analogy between the individual mind and the collective mind of the nation. This is a much closer and more illuminating analogy than that between the nation, or society, and the material organism. The latter analogy has been developed in detail by H. Spencer, Schäffle[78] and others; it has now fallen into some disrepute. It has no doubt a certain value, but it is popularly used in a way that leads to quite unjustifiable conclusions. Of these fallacies by far the most commonly accepted is that which asserts that, just as every animal organism inevitably grows old and dies, so too must nations.

This is one of the most popular dogmas of amateur philosophers, and so distinguished a statesman as the late Lord Salisbury gave it countenance; while Mr A. J. Balfour in his recent Sidgwick Memorial Lecture[79] courageously breaks away and proposes to substitute for senility as the cause of decay the word decadence—a proposal which merely implies that he trusts less to the analogical argument from the material organism and more to empirical induction, to the observation of the fact that so many nations have decayed.

All this serves to illustrate the dangers of analogy. We need no special cause to account for the fall and the decay of nations, no obscure principle of senility or decadence; the wonderful thing is that they exist at all; and what needs explanation is not so much the decay of some, but rather the long persistence of others.
