And since the other racial elements of the European population, at least the two main ones, do not differ at all radically from the blond in their native capacities, it is likewise to be presumed that they also emerged from a mutation under circumstances of culture, and especially of technology, not radically different in degree from those that first surrounded the blond. The difference between these three racial stocks is much more evident in their physical traits than in their instinctive gifts or their intellectual capacity; and yet the similarity of the three is so great and distinctive even on the physical side that anthropologists are inclined to class the three together as all and several distinctively typical of a “white” or “caucasic” race, to which they are held collectively to belong. Something to the like effect seems to hold true for the distinctive groups of racial stocks that have made the characteristic civilisations of the Far East on the one hand and of southern Asia on the other hand; and something similar might, again, be said for the group of stocks that were concerned in the ancient civilisations of America. It may be pertinent to add that, except for a long antecedent growth of technology, that is to say a long continued cumulative experience in workmanship, with the resultant accumulated knowledge of the ways and means of life, none of the characteristic races of Europe could have survived. In the absence of these antecedent technological gains, together with the associated growth of institutions, such mutants, with their characteristic gifts and limitations, must have perished. * * * * *
