Now, assuming that this is a true account of the evolution of civilisation during the past, is it essential that the same methods of selection must dominate the future? Or are there any forces which have been coming into play during the later periods of human history that deeply modify, suspend, and even reverse the operations of selective forces that dominate the rest of nature?
In the very work from which I quote, Professor Pearson furnishes a complete answer to his own contention for the necessity of this physical struggle between races.
In the last sentence of the passage given above, he seems to recognise the utility in lower races of the physical
