How about "darkest Africa"? Here surely we have a case of degeneration beyond all hope of recovery, not to mention a great future. But is this quite as certain as some of us seem to think? Is not much of our so-called Occidental progress really an orgy of wasted energy, neurotic excitement, half-camouflaged decadence, which will end in degeneration? We do not know yet. May there some day be a family rather than league of nations to which every one will contribute according to its special ability? If this be granted, will Huxley's statement concerning the individual be applicable to races and peoples: "Its aim will be not so much the survival of the fittest as the fitting of as many as possible to survive"? These are sphinx questions demanding an answer from statesmen. Unfortunately most of our statesmen are only waiting to be gathered to their fathers in the graveyard of dead politicians. We will turn homeward after our excursion, gladly leaving our little bundle of facts and questions at the door of the philosopher of history. But one question confronts us directly. Is our whole estimate and valuation of Neolithic life, work, and progress extreme and practically worthless? Were they, in spite of all our arguments, a mob of crude, worthless barbarians, undeserving of any gratitude or sympathy, much less of respect? Do we really owe anything to them? One historic event of great importance had its growth and rise during the Neolithic period out of Neolithic life, conditions, and culture. This was the Aryan culture of Persia and India, of Greece and Rome, and of our northern ancestors. No one seems to deny its importance and value. We must glance at its origin and growth, and see if it supports at all the tentative and often conjectural conclusions at which we have arrived. This will be the object of our work and study in the next and closing chapter. CHAPTER XII THE COMING OF THE INDO-EUROPEANS Said Max Müller in his _Biographies of Words_: "I have declared again and again that, if I say Aryan, I mean neither blood nor bones, nor hair nor skull; I mean simply those who speak an Aryan language. The same applies to Hindus, Greeks, Romans, Germans, Celts, and Slavs. When I speak of them I commit myself to no anatomical characteristics. The blue-eyed and fair-haired Scandinavians may have been conquerors or conquered, they may have adopted the language of their darker lords or their subjects, or vice versa. I assert nothing beyond their language.... To me an ethnologist who speaks of Aryan race, Aryan blood, Aryan eyes and hair, is as great a sinner as a linguist who speaks of a dolichocephalic dictionary or a brachycephalic grammar."
