suppose, then we should be naturally induced to imagine that those customs alien in their essential nature to the soil and climate of Japan were imported by those immigrants from the tropical South who, insignificant, not only in number, but also in influence, have, notwithstanding, taken a firm root in the historical and social life of the Japanese, struggling against the opposition of overwhelming odds, far more numerous, civilised, and powerful, an utterly impossible hypothesis. How then, did such an incongruous idea with its fatal conclusions come to be entertained by scholars? Because they have too great a faith in the power of civilisation, so-called, to decide the rise and fall of races in the primitive age. Those who would uphold the assumption of the northern origin of the Japanese, or at least of its ruling class, tacitly presuppose that the northeastern Asiatics of the prehistoric age were several steps ahead of the contemporary tropical peoples in the progress of civilisation, or at least that one of the many tribes of northeastern Asia was far superior to its neighbours as regards civilisation. Otherwise they think that a certain stock of people, which afterwards became the ruling class in Japan, had attained already the civilisation of the iron age while they were still on the continent, so that when they came over to Japan they would have been far more advanced than the people who had settled in Japan before them. Though it is but a conjecture, it is good so far as it goes. To deduce the domination over alien races simply from the superiority of the civilisation must be another thing. Even in modern times, sheer valour often tells more than superiority of arms in deciding the fate of battles. This must have been even more true in early ages. The empire of Rome was broken asunder by the semi-civilised Germans. In the East, China was repeatedly overrun by nomadic tribes far inferior to the Chinese in civilisation. What is true in this respect in historic times, must be particularly true in prehistoric ages. It is too superficial to think that a tribe in the stage of the iron age must necessarily conquer in fighting against other tribes knowing and using stone weapons only. In those ages it is strength, ferocity, courage, which tell decidedly more in fighting than any weapon. We need not therefore take much account of the state of civilisation among different primitive tribes in determining the origin of the Japanese race.
