process of senility can happen only if a people loses the racial cell which originally had been creative or if the outside influence should be withdrawn after having awakened and maintained the first cultural developments in that region. If it be shown that a people owes the fundamental elements of its culture to foreign races, assimilating and elaborating such elements, and if subsequently that culture becomes fossilized whenever the external influence ceases, then such a race may be called the depository but never the creator of a culture.

If we subject the different peoples to a strict test from this standpoint we shall find that scarcely any one of them has originally created a culture, but almost all have been merely the recipients of a culture created elsewhere.

This development may be depicted as always happening somewhat in the following way:

Aryan tribes, often almost ridiculously small in number, subjugated foreign peoples and, stimulated by the conditions of life which their new country offered them (fertility, the nature of the climate, etc.), and profiting also by the abundance of manual labour furnished them by the inferior race, they developed intellectual and organizing faculties which had hitherto been dormant in these conquering tribes. Within the course of a few thousand years, or even centuries, they gave life to cultures whose primitive traits completely corresponded to the character of the founders, though modified by adaptation to the peculiarities of the soil and the characteristics of the subjugated people. But finally the conquering race offended against the principles which they first had observed, namely, the maintenance of their racial stock unmixed, and they began to intermingle with the subjugated people. Thus they put an end to their own separate existence; for the original sin committed in Paradise has always been followed by the expulsion of the guilty parties.

After a thousand years or more the last visible traces of those former masters may then be found in a lighter tint of the skin which the Aryan blood had bequeathed to the subjugated race, and in a fossilized culture of which those Aryans had been the original creators. For just as the blood. of the conqueror, who was a conqueror not only in body but also in spirit, got submerged in the blood of the subject race, so the substance disappeared out of which the torch of human culture and progress was kindled. In so far as the blood of the former ruling race has left a light nuance of colour in the blood of its descendants, as a token and a memory, the night of cultural life is rendered less dim and dark by a mild light radiated from the products of those who were the bearers of the original fire. Their radiance shines across the barbarism to which the subjected race has reverted and might often lead the superficial observer to believe that he sees before him an image of the present race when he is really looking into a mirror wherein only the past is reflected.

It may happen that in the course of its history such a people will come into contact a second time, and even oftener, with the original founders of their culture and may not even remember that distant association. Instinctively the remnants of blood left from that old ruling race will be drawn towards this new phenomenon and what had formerly been possible only under compulsion can now be successfully achieved in a voluntary way. A new cultural wave flows in and lasts until the blood of its standard-bearers becomes once again adulterated by intermixture with the originally conquered race.

It will be the task of those who set themselves to the study of a universal history of civilization to investigate history from this point of view instead of allowing themselves to be smothered under the mass of external data, as is only too often the case with our present historical science.

This short sketch of the changes that take place among those races that are only the depositories of a culture also furnishes a picture of the development and the activity and the disappearance of those who are the true founders of culture on this earth, namely the Aryans themselves.

Just as in our daily life the so-called man of genius needs a particular occasion, and sometimes indeed a special stimulus, to bring his genius to light, so too in the life of the peoples the race that has genius in it needs the occasion and stimulus to
