Now, the fact that all early populations were highly mobile is unquestionable. In it, for example, lies the secret of the Libyan problem. The Libyans or their predecessors spoke Hamitic, but, as shown even by old Egyptian reliefs, they were all blond and blue-eyed and, therefore, doubtless of North-European provenance.[224] In Asia Minor at least three migration-strata since 1300 have been determined, which are related probably to the attacks of the “Sea-peoples” in Egypt, and something similar has been shown in the Mexican Culture. But as to the nature of these movements we know nothing at all. In any case, there can be no question of migrations such as modern historians like to picture--movements of close-pressed peoples traversing the lands in great masses, pushing and being pushed till finally they come to rest somewhere or other. It is not the alterations in themselves, but the conceptions we have formed about them, that have spoilt our outlook upon the nature of the peoples. Peoples in the modern sense of the word do not wander, and that which of old _did_ wander needs to be very carefully examined before it is labelled, as the label will not always stand for the same thing. The motive, too, that is everlastingly assigned to these migrations is colourless and worthy of the century that invented it--material necessity. Hunger would normally lead to efforts of quite a different sort, and it has certainly been only the last of the motives that drove men of race out of their nests--although it is understandable that it would very frequently make itself felt when such bands suddenly encountered a military obstacle. It was doubtless, in this simple and strong kind of man, the primary microcosmic urgency to move in free space which sprang up out of the depths of his soul as love of adventure, daring, liking for power and booty; as a blazing desire, to us almost incomprehensible, for deeds, for joy of carnage, for the death of the hero. Often, too, no doubt, domestic strife or fear of the revenge of the stronger, was the motive, but again a strong and manly one. Motives like these are infectious--the “man who stays at home” is a coward. Was it common bodily hunger, again, that induced the Crusades, or the expeditions of Cortez and Pizarro, or in our time the ventures of “wild west” pioneers? Where, in history, we find the little handful invading wide lands, it is ever the voices of the blood, the longing for high destinies, that drive them. Further, we have to consider the position in the country traversed by the invaders. Its characteristics are always modified more or less, but the modifications are due not merely to the influence of the immigrants, but more and more to the nature of the settled population, which in the end becomes numerically overwhelming.
