Germany is pre-eminently a country in which the world movement of to-day in all of its multitudinous aspects is plainly visible. The life of this University covers the period during which that movement has spread until it is felt throughout every continent; while its velocity has been constantly accelerating, so that the face of the world has changed, and is now changing, as never before. It is therefore fit and appropriate here to speak on this subject.

When, in the slow procession of the ages, man was developed on this planet, the change worked by his appearance was at first slight. Further ages passed, while he groped and struggled by infinitesimal degrees upward through the lower grades of savagery; for the general law is that life which is advanced and complex, whatever its nature, changes more quickly than simpler and less advanced forms. The life of savages changes and advances with extreme slowness, and groups of savages influence one another but little. The first rudimentary beginnings of that complex life of communities which we call civilization marked a period when man had already long been by far the most important creature on the planet. The history of the living world had become, in fact, the history of man, and therefore something totally different in kind as well as in degree from what it had been before. There are interesting analogies between what has gone on in the development of life generally and what has gone on in the development of human society, and these I shall discuss elsewhere.[[9]] But the differences are profound, and go to the root of things.

Throughout their early stages the movements of civilization—for, properly speaking, there was no one movement—were very slow, were local in space, and were partial in the sense that each developed along but few lines. Of the numberless years that covered these early stages we have no record. They were the years that saw such extraordinary discoveries and inventions as fire, and the wheel, and the bow, and the domestication of animals. So local were these inventions that at the present day there yet linger savage tribes, still fixed in the half-bestial life of an infinitely remote past, who know none of them except fire—and the discovery and use of fire may have marked, not the beginning of civilization, but the beginning of the savagery which separated man from brute.

Even after civilization and culture had achieved a relatively high position, they were still purely local, and from this fact subject to violent shocks. Modern research has shown the existence in prehistoric or, at least, protohistoric times of many peoples who, in given localities, achieved a high and peculiar culture, a culture that was later so completely destroyed that it is difficult to say what, if any, traces it left on the subsequent cultures out of which we have developed our own; while it is also difficult to say exactly how much any one of these cultures influenced any other. In many cases, as where invaders with weapons of bronze or iron conquered the neolithic peoples, the higher civilization completely destroyed the lower civilization, or barbarism, with which it came in contact. In other cases, while superiority in culture gave its possessors at the beginning a marked military and governmental superiority over the neighboring peoples, yet sooner or later there accompanied it a certain softness or enervating quality which left the cultured folk at the mercy of the stark and greedy neighboring tribes, in whose savage souls cupidity gradually overcame terror and awe. Then the people that had been struggling upward would be engulfed, and the levelling waves of barbarism wash over them. But we are not yet in position to speak definitely on these matters. It is only the researches of recent years that have enabled us so much as to guess at the course of events in prehistoric Greece; while as yet we can hardly even hazard a guess as to how, for instance, the Hallstadt culture rose and fell, or as to the history and fate of the builders of those strange ruins of which Stonehenge is the type.

The first civilizations which left behind them clear records rose in that hoary historic past which geologically is part of the immediate present—and which is but a span's length from the present, even when compared only with the length of time that man has lived on this planet. These first civilizations were those which rose in Mesopotamia and the Nile valley some six or eight thousand years ago. As far as we can see, they were well-nigh independent centres of cultural development, and our knowledge is not such at present as to enable us to connect either with the early cultural movements, in southwestern Europe on the one hand, or in India on the other, or with that Chinese civilization which has been so profoundly affected by Indian influences.

Compared with the civilizations with which we are best acquainted, the striking features in the Mesopotamian and Nilotic civilizations were the length of time they endured and their comparative changelessness. The kings, priests, and peoples who dwelt by the Nile or Euphrates are found thinking much the same thoughts, doing much the same deeds, leaving at least very similar records, while time passes in tens of centuries. Of course there was change; of course there were action and reaction in influence between them and their neighbors; and the movement of change, of development, material, mental, spiritual, was much faster than anything that had occurred during the æons of mere savagery. But in contradistinction to modern times the movement was very slow indeed, and, moreover, in each case it was strongly localized; while the field of endeavor was narrow. There were certain conquests by man over nature; there were certain conquests in the domain of pure intellect; there were certain extensions which spread the area of civilized mankind. But it would be hard to speak of it as a "world movement" at all; for by far the greater part of the habitable globe was not only unknown, but its existence unguessed at, so far as peoples with any civilization whatsoever were concerned.

With the downfall of these ancient civilizations there sprang into prominence those peoples with whom our own cultural history may be said to begin. Those ideas and influences in our lives which we can consciously trace back at all are in the great majority of instances to be traced to the Jew, the Greek, or the Roman; and the ordinary man, when he speaks of the nations of antiquity, has in mind specifically these three peoples—although, judged even by the history of which we have record, theirs is a very modern antiquity indeed.

The case of the Jew was quite exceptional. His was a small nation, of little more consequence than the sister nations of Moab and Damascus, until all three, and the other petty states of the country, fell under the yoke of the alien. Then he survived, while all his fellows died. In the spiritual domain he contributed a religion which has been the most potent of all factors in its effect on the subsequent history of mankind; but none of his other contributions compare with the legacies left us by the Greek and the Roman.

The Græco-Roman world saw a civilization far more brilliant, far more varied and intense, than any that had gone before it, and one that affected a far larger share of the world's surface. For the first time there began to be something which at least foreshadowed a "world movement" in the sense that it affected a considerable portion of the world's surface and that it represented what was incomparably the most important of all that was happening in world history at the time. In breadth and depth the field of intellectual interest had greatly broadened at the same time that the physical area affected by the civilization had similarly extended. Instead of a civilization affecting only one river valley or one nook of the Mediterranean, there was a civilization which directly or indirectly influenced mankind from the Desert of Sahara to the Baltic, from the Atlantic Ocean to the westernmost mountain chains that spring from the Himalayas. Throughout most of this region there began to work certain influences which, though with widely varying intensity, did nevertheless tend to affect a large portion of mankind. In many of the forms of science, in almost all the forms of art, there was great activity. In addition to great soldiers there were great administrators and statesmen whose concern was with the fundamental questions of social and civil life. Nothing like the width and variety of intellectual achievement and understanding had ever before been known; and for the first time we come across great intellectual leaders, great philosophers and writers, whose works are a part of all that is highest in modern thought, whose writings are as alive to-day as when they were first issued; and there were others of even more daring and original temper, a philosopher like Democritus, a poet like Lucretius, whose minds leaped ahead through the centuries and saw what none of their contemporaries saw, but who were so hampered by their surroundings that it was physically impossible for them to leave to the later world much concrete addition to knowledge. The civilization was one of comparatively rapid change, viewed by the standard of Babylon and Memphis. There was incessant movement; and, moreover, the whole system went down with a crash to seeming destruction after a period short compared with that covered by the reigns of a score of Egyptian dynasties, or with the time that elapsed between a Babylonian defeat by Elam and a war sixteen centuries later which fully avenged it.

This civilization flourished with brilliant splendor. Then it fell. In its northern seats it was overwhelmed by a wave of barbarism from among those half-savage peoples from whom you and I, my hearers, trace our descent. In the south and east it was destroyed later, but far more thoroughly, by invaders of an utterly different type. Both conquests were of great importance; but it was the northern conquest which in its ultimate effects was of by far the greatest importance.
