ordinary pitch of patriotic sentiment as between any two widely diverse samples of these hybrid populations, in spite of the fact that the diversity in visible physical traits may be quite pronounced. In short, the conclusion seems safe, on the whole, that in this respect the several racial stocks that have gone to produce the existing populations of Christendom have all been endowed about as richly one as another. Patriotism appears to be a ubiquitous trait, at least among the races and peoples of Christendom. From which it should follow, that since there is, and has from the beginning been, no differential advantage favoring one racial stock or one fashion of hybrid as against another, in this matter of patriotic animus, there should also be no ground of selective survival or selective elimination on this account as between these several races and peoples. So that the undisturbed and undiminished prevalence of this trait among the European population, early or late, argues nothing as to its net serviceability or disserviceability under any of the varying conditions of culture and technology to which these Europeans have been subjected, first and last; except that it has, in any case, not proved so disserviceable under the conditions prevailing hitherto as to result in the extinction of these Europeans, one with another.[4] [Footnote 4: For a more extended discussion of this matter, cf. _Imperial Germany and the Industrial Revolution_, ch. i. and Supplementary Notes i. and ii.]
