So deeply rooted a growth or culture is almost ineradicable, though it has a marvellous adaptability and possibilities of growth and modification. It could never have been destroyed by its own Indo-European children, however rebellious. It must survive somewhere though probably changed for the better. We have found reasons to doubt whether Roman capacity for discipline and government, Roman laws and institutions, were predominantly of Indo-European origin. We were still more doubtful whether the glory of Teutonic or Scandinavian history is due to its being Indo-European, or whether it was the result of a continuous, unbroken development from Neolithic times. If ever any culture seems largely native and indigenous, responsive to outside influences but always retaining its independent self-determination and power of selection and choice as to what and how far it will assimilate, that culture is to be found in northern Germany and Scandinavia. We have seen the fate of Olympian religion and Achæan thought in Greece. The Achæans were a small minority completely outnumbered by an exceedingly conservative native population. They were absorbed and became a part of the Greek people, and their contribution must not be underestimated. We have noted the marvellous vitality of the old Neolithic thought, its re-emergence, its influence on Greek philosophy. We remember that the great seat of progress was not in Dorian Sparta but in "Pelasgic Athens," almost unknown to Homer. The Celt was, if anything, a better "mixer" and more adaptable than even the Achæan. His prejudices and zeal in regard to morals and religion seem not to have been deep or strong. The Celts were finally absorbed, affecting the temper of the people far more than their daily life. Through all these revolutions, as well as those which were to follow, family and neighborhood retained their compact unity, perhaps with all its mutual attractions strengthened by the pressure of the conquerors. They were still the controlling influence in the life and education of the individual, as they probably remain to this day. The power of these smaller communities may have waxed, as tribal control waned. What they had lost in the mutual support within the tribe they made good by leaning more closely on their neighbors. This solidarity makes the common people very stiff-necked, in an excellent sense of the word. Like the Neolithic folk of Scandinavia, they select and accept from their more cultured neighbors only that which they can assimilate to the stores of experience and instincts which they already possess. The fickleness, of which they are often accused, is characteristic of a very different class or stratum of the population, and of far later origin and development. Their own development is naturally slow, gradual, and continuous.
