The history of the development of culture since the time of the Greeks is short enough, when we take into consideration the actual ground it covers, and ignore the periods during which man stood still, went backwards, hesitated or strayed. The Hellenising of the world--and to make this possible, the Orientalising of Hellenism--that double mission of Alexander the Great, still remains the most important event: the old question whether a foreign civilisation may be transplanted is still the problem that the peoples of modern times are vainly endeavouring to solve. The rhythmic play of those two factors against each other is the force that has determined the course of history heretofore. Thus Christianity appears, for instance, as a product of Oriental antiquity, which was thought out and pursued to its ultimate conclusions by men, with almost intemperate thoroughness. As its influence began to decay, the power of Hellenic culture was revived, and we are now experiencing phenomena so strange that they would hang in the air as unsolved problems, if it were not possible, by spanning an enormous gulf of time, to show their relation to analogous phenomena in Hellenistic culture. Thus, between Kant and the Eleatics, Schopenhauer and Empedocles, AEschylus and Wagner, there is so much relationship, so many things in common, that one is vividly impressed with the very relative nature of all notions of time. It would even seem as if a whole diversity of things were really all of a piece, and that time is only a cloud which makes it hard for our eyes to perceive the oneness of them. In the history of the exact sciences we are perhaps most impressed by the close bond uniting us with the days of Alexander and ancient Greece. The pendulum of history seems merely to have swung back to that point from which it started when it plunged forth into unknown and mysterious distance. The picture represented by our own times is by no means a new one: to the student of history it must always seem as though he were merely in the presence of an old familiar face, the features of which he recognises. In our time the spirit of Greek culture is scattered broadcast. While forces of all kinds are pressing one upon the other, and the fruits of modern art and science are offering themselves as a means of exchange, the pale outline of Hellenism is beginning to dawn faintly in the distance. The earth which, up to the present, has been more than adequately Orientalised, begins to yearn once more for Hellenism. He who wishes to help her in this respect will certainly need to be gifted for speedy action and to have wings on his heels, in order to synthetise the multitudinous and still undiscovered facts of science and the many conflicting divisions of talent so as to reconnoitre and rule the whole enormous field. It is now necessary that a generation of anti-Alexanders should arise, endowed with the supreme strength necessary for gathering up, binding together, and joining the
