So much greater is the whole than the sum of its existing parts, that it might well seem right to sacrifice the welfare and happiness of one or two or more generations, and even the lives of the majority of the citizens, if that were necessary to the preservation and future welfare of the whole nation as such. This is no merely theoretical distinction, it is one of the highest practical importance, which we may illustrate in two ways. A whole nation may be confronted with the alternative, may be forced to choose between the good of all and the good of the whole. Such a choice was, it may be said without exaggeration, suddenly presented to the Belgian people, and only less acutely to ourselves and to Italy, by the recent European conflagration; and in each case the good of the whole has been preferred. Is it not probable and obvious that, if each or all of these peoples had consented to the domination of Germany, the material welfare of all their existing citizens might well have been increased, rather than diminished, and that their choice has involved not only the loss of life of large numbers of their citizens and great sufferings for nearly all the others, but also enormous sacrifice of material prosperity, in order that the whole may survive and eventually prosper as a nation working out its national destiny free from external domination? There are, or were, those who say that they would just as soon live under German rule, because they would be governed at least as well and perhaps better than by their own government hitherto; and there is perhaps nothing intrinsically bad or wrong in this attitude; the question of its rightness or wrongness turns wholly on the valuation of nationality. It is easier to appreciate this plea on behalf of another people than our own. One may hear it said even now that, after all, it would have been better for Belgium that she should have entered into the group of Germanic powers in some sort of federal system or Customs union; that, in general, it is ridiculous that the small states should claim sovereign powers and pretend to have their own foreign policy and so forth; that they are struggling against the inevitable, against a universal and necessary tendency for the absorption of the smaller states by the larger.
