So, when we speak of the ‘death’ of a tribe, a nation, or a civilization, the term may be used for either one of two totally different processes, the analogy with what occurs in biological history being complete. Certain tribes of savages, the Tasmanians, for instance, and various little clans of American Indians, have within the last century or two completely died out; all of the individuals have perished, leaving no descendants, and the blood has disappeared. Certain other tribes of Indians have as tribes disappeared or are now disappearing; but their blood remains, being absorbed into the veins of the white intruders, or of the black men introduced by those white intruders; so that in reality they are merely being transformed into something absolutely different from what they were. In the United States, in the new State of Oklahoma, the Creeks, Cherokees, Chickasaws, Delawares, and other tribes, are in process of absorption into the mass of the white population; when the state was admitted a couple of years ago, one of the two senators, and three of the five representatives in Congress, were partly of Indian blood. In but a few years these Indian tribes will have disappeared as completely as those that have actually died out; but the disappearance will be by absorption and transformation into the mass of the American population.

A like wide diversity in fact may be covered in the statement that a civilization has ‘died out.’ The nationality and culture of the wonderful city-builders of the lower Mesopotamian Plain have completely disappeared, and, though doubtless certain influences dating therefrom are still at work, they are in such changed and hidden form as to be unrecognizable. But the disappearance of the Roman Empire was of no such character. There was complete change, far-reaching transformation, and at one period a violent dislocation; but it would not be correct to speak either of the blood or the culture of old Rome as extinct. We are not yet in a position to dogmatize as to the permanence or evanescence of the various strains of blood that go to make up every civilized nationality; but it is reasonably certain that the blood of the old Roman still flows through the veins of the modern Italian; and though there has been much intermixture, from many different foreign sources—from foreign conquerors and from foreign slaves—yet it is probable that the Italian type of to-day finds its dominant ancestral type in the ancient Latin. As for the culture, the civilization of Rome, this is even more true. It has suffered a complete transformation, partly by natural growth, partly by absorption of totally alien elements, such as a Semitic religion, and certain Teutonic governmental and social customs; but the process was not one of extinction, but one of growth and transformation, both from within and by the accretion of outside elements. In France and Spain the inheritance of Latin blood is small; but the Roman culture which was forced on those countries has been tenaciously retained by them, throughout all their subsequent ethnical and political changes, as the basis on which their civilizations have been built. Moreover, the permanent spreading of Roman influence was not limited to Europe. It has extended to and over half of that new world which was not even dreamed of during the thousand years of brilliant life between the birth and the death of Pagan Rome. This new world was discovered by one Italian, and its mainland first reached and named by another; and in it, over a territory many times the size of Trajan’s empire, the Spanish, French and Portuguese adventurers founded, beside the St. Lawrence and the Amazon, along the flanks of the Andes and in the shadow of the snow-capped volcanoes of Mexico, from the Rio Grande to the Straits of Magellan, communities, now flourishing and growing apace, which in speech and culture, and even as regards one strain in their blood, are the lineal heirs of the ancient Latin civilization. When we speak of the disappearance, the passing away, of ancient Babylon or Nineveh, and of ancient Rome, we are using the same terms to describe totally different phenomena.

The anthropologist and historian of to-day realize much more clearly than their predecessors of a couple of generations back how artificial most great nationalities are, and how loose is the terminology usually employed to describe them. There is an element of unconscious and rather pathetic humour in the simplicity of half a century ago which spoke of the Aryan and the Teuton with reverential admiration, as if the words denoted, not merely something definite, but something ethnologically sacred; the writers having much the same pride and faith in their own and their fellow countryman’s purity of descent from these imaginary Aryan or Teutonic ancestors that was felt a few generations earlier by the various noble families who traced their lineage direct to Odin, Aeneas, or Noah. Nowadays, of course, all students recognize that there may not be, and often is not, the slightest connexion between kinship in blood and kinship in tongue. In America we find three races, white, red, and black, and three tongues, English, French, and Spanish, mingled in such a way that the lines of cleavage of race continually run at right angles to the lines of cleavage of speech; there being communities practically of pure blood of each race found speaking each language. Aryan and Teutonic are terms having very distinct linguistic meanings; but whether they have any such ethnical meanings as were formerly attributed to them, is so doubtful that we cannot even be sure whether the ancestors of most of those we call Teutons originally spoke an Aryan tongue at all. The term Celtic, again, is perfectly clear when used linguistically; but when used to describe a race it means almost nothing until we find out which one of several totally different terminologies the writer or speaker is adopting. If, for instance, the term is used to designate the short-headed, medium-sized type common throughout middle Europe, from east to west, it denotes something entirely different from what is meant when the name is applied to the tall, yellow-haired opponents of the Romans and the later Greeks; while if used to designate any modern nationality, it becomes about as loose and meaningless as the term Anglo-Saxon itself.

Most of the great societies which have developed a high civilization and have played a dominant part in the world have been—and are—artificial; not merely in social structure, but in the sense of including totally different race types. A great nation rarely belongs to any one race, though its citizens generally have one essentially national speech. Yet the curious fact remains that these great artificial societies acquire such unity that in each one all the parts feel a subtle sympathy, and move or cease to move, go forward or go back, all together, in response to some stir or throbbing, very powerful, and yet not to be discerned by our senses. National unity is far more apt than race unity to be a fact to reckon with; until indeed we come to race differences as fundamental as those which divide from one another the half-dozen great ethnic divisions of mankind, when they become so important that differences of nationality, speech, and creed sink into littleness.

An ethnological map of Europe in which the peoples were divided according to their physical and racial characteristics, such as stature, coloration, and shape of head, would bear no resemblance whatever to a map giving the political divisions, the nationalities, of Europe; while on the contrary a linguistic map would show a general correspondence between speech and nationality. The northern Frenchman is in blood and physical type more nearly allied to his German-speaking neighbour than to the Frenchman of the Mediterranean seaboard; and the latter, in his turn, is nearer to the Catalan than to the man who dwells beside the Channel or along the tributaries of the Rhine. But in essential characteristics, in the qualities that tell in the make-up of a nationality, all these kinds of Frenchmen feel keenly that they are one, and are different from all outsiders, their differences dwindling into insignificance, compared with the extraordinary, artificially produced, resemblances which bring them together and wall them off from the outside world. The same is true when we compare the German who dwells where the Alpine springs of the Danube and the Rhine interlace, with the physically different German of the Baltic lands. The same is true of Kentishman, Cornishman, and Yorkshireman in England.

In dealing, not with groups of human beings in simple and primitive relations, but with highly complex, highly specialized, civilized, or semi-civilized societies, there is need of great caution in drawing analogies with what has occurred in the development of the animal world. Yet even in these cases it is curious to see how some of the phenomena in the growth and disappearance of these complex, artificial groups of human beings resemble what has happened in myriads of instances in the history of life on this planet.

Why do great artificial empires, whose citizens are knit by a bond of speech and culture much more than by a bond of blood, show periods of extraordinary growth, and again of sudden or lingering decay? In some cases we can answer readily enough; in other cases we cannot as yet even guess what the proper answer should be. If in any such case the centrifugal forces overcome the centripetal, the nation will of course fly to pieces, and the reason for its failure to become a dominant force is patent to every one. The minute that the spirit which finds its healthy development in local self-government, and is the antidote to the dangers of an extreme centralization, develops into mere particularism, into inability to combine effectively for achievement of a common end, then it is hopeless to expect great results. Poland and certain Republics of the western hemisphere are the standard examples of failure of this kind; and the United States would have ranked with them, and her name would have become a byword of derision, if the forces of union had not triumphed in the Civil War. So, the growth of soft luxury after it has reached a certain point becomes a national danger patent to all. Again, it needs but little of the vision of a seer to foretell what must happen in any community if the average woman ceases to become the mother of a family of healthy children, if the average man loses the will and the power to work up to old age and to fight whenever the need arises. If the homely, commonplace virtues die out, if strength of character vanishes in graceful self-indulgence, if the virile qualities atrophy, then the nation has lost what no material prosperity can offset.

But there are plenty of other phenomena wholly or partially inexplicable. It is easy to see why Rome trended downward when great slave-tilled farms spread over what had once been a country-side of peasant proprietors, when greed and luxury and sensuality ate like acids into the fibre of the upper classes, while the mass of the citizens grew to depend not upon their own exertions, but upon the state, for their pleasures and their very livelihood. But this does not explain why the forward movement stopped at different times, so far as different matters were concerned; at one time as regards literature, at another time as regards architecture, at another time as regards city-building. There is nothing mysterious about Rome’s dissolution at the time of the barbarian invasions; apart from the impoverishment and depopulation of the Empire, its fall would be quite sufficiently explained by the mere fact that the average citizen had lost the fighting edge, an essential even under a despotism, and therefore far more essential in free, self-governing communities such as those of the English-speaking peoples of to-day. The mystery is rather that out of the chaos and corruption of Roman society during the last days of the oligarchic republic, there should have sprung an Empire able to hold things with reasonable steadiness for three or four centuries. But why, for instance, should the higher kinds of literary productiveness have ceased about the beginning of the second century, whereas the following centuries witnessed a great outbreak of energy in the shape of city-building in the provinces, not only in Western Europe, but in Africa? We cannot even guess why the springs of one kind of energy dried up, while there was yet no cessation of another kind.

Take another and smaller instance, that of Holland. For a period covering a little more than the seventeenth century, Holland, like some of the Italian city states at an earlier period, stood on the dangerous heights of greatness, beside nations so vastly her superior in territory and population as to make it inevitable that sooner or later she must fall from the glorious and perilous eminence to which she had been raised by her own indomitable soul. Her fall came; it could not have been indefinitely postponed; but it came far quicker than it needed to come, because of shortcomings on her part to which both Great Britain and the United States would be wise to pay heed. Her government was singularly ineffective, the decentralization being such as often to permit the separatist, the particularist, spirit of the provinces to rob the central authority of all efficiency. This was bad enough. But the fatal weakness was that so common in rich, peace-loving societies, where men hate to think of war as possible, and try to justify their own reluctance to face it either by high-sounding moral platitudes, or else by a philosophy of short-sighted materialism. The Dutch were very wealthy. They grew to believe that they could hire others to do their fighting for them on land; and on sea, where they did their own fighting, and fought very well, they refused in time of peace to make ready fleets so efficient, as either to insure them against the peace being broken, or else to give them the victory when war came. To be opulent and unarmed is to secure ease in the present at the almost certain cost of disaster in the future.

It is therefore easy to see why Holland lost when she did her position among the powers; but it is far more difficult to explain why at the same time there should have come at least a partial loss of position in the world of art and letters. Some spark of divine fire burned itself out in the national soul. As the line of great statesmen, of great warriors, by land and sea, came to an end, so the line of the great Dutch painters ended. The loss of pre-eminence in the schools followed the loss of pre-eminence in camp and in council chamber.
