They indicate the great extent to which war affects the human breed, but they do not show that war affects the quality of the breed, and until that is shown the eugenist remains undisturbed.
There are various circumstances which, at the outset, and even in the absence of experimental verification, make it difficult, or impossible, that even the bare mortality of war (for the eugenical bearings of war are not confined to its mortality) should leave the eugenist indifferent. For war never hits men at random. It only hits a carefully selected percentage of "fit" men. It tends, in other words, to strike out, temporarily, or in a fatal event, permanently, from the class of fathers, precisely that percentage of the population which the eugenist wishes to see in that class. This is equally the case in countries with some form of compulsory service, and in countries which rely on a voluntary military system. For, however an army is recruited, it is only those men reaching a fairly high standard of fitness who are accepted, and these, even in times of peace are hampered in the task of carrying on the race, which the less fit and the unfit are free to do at their own good pleasure. Nearly all the ways in which war and armies disturb the normal course of affairs seem likely to interfere with eugenical breeding, and none to favour it. Thus at one time, in the Napoleonic wars, the French age of conscription fell to eighteen, while marriage was a cause of exemption, with the result of a vast increase of hasty and ill-advised marriages among boys, certainly injurious to the race. Armies, again, are highly favourable to the spread of racial poisons, especially of syphilis, the most dangerous of all, and this cannot fail to be, in a marked manner, dysgenic rather than eugenic.
The Napoleonic wars furnished the first opportunity of testing the truth of Franklin's assertion concerning the disastrous effect of armies on the race, by the collection of actual and precise data. But the significance of the data proved unexpectedly difficult to unravel, and most writers on the subject have been largely occupied in correcting the mistakes of their predecessors. Villermé in 1829 remarked that the long series of French wars up to 1815 must probably reduce the height of the French people, though he was unable to prove that this was so. Dufau in 1840 was in a better position to judge, and he pointed out in his Traité de Statistique that, comparing 1816 and 1835, the number of young men exempted from the army had doubled in the interval, even though the regulation height had been lowered. This result, however, he held, was not so alarming as it might appear, and probably only temporary, for it was seemingly due to the fact that, in 1806 and the following years, the male population was called to arms in masses, even youths being accepted, so that a vast number of precocious marriages of often defective men took place. The result would only be terrible, Dufau believed, if prolonged; his results, however, were not altogether reliable, for he failed to note the proportion of men exempted to those examined. The question was investigated more thoroughly by Tschuriloff in 1876.9 He came to the conclusion that the Napoleonic wars had no great influence on stature, since the regulation height was lowered in 1805, and abolished altogether for healthy men in 1811, and any defect of height in the next generation is speedily repaired. Tschuriloff agreed, however, that, though the influence of war in diminishing the height of the race is unimportant, the influence of war in increasing physical defects and infirmities in subsequent generations is a very different matter. He found that the physical deterioration of war manifested itself chiefly in the children born eight years afterwards, and therefore in the recruits twenty-eight years after the war. He regarded it as an undoubted fact that the French army of half a million men in 1809 increased by 3 per cent. the proportion of hereditarily infirm persons. He found, moreover, that the new-born of 1814, that is to say the military class of 1834, showed that infirmities had risen from 30 per cent. to 45.8 per cent., an increase of 50 per cent. Nor is the status quo entirely brought back later on, for the bad heredity of the increased number of defectives tends to be still further propagated, even though in an attenuated form. As a matter of fact, Tschuriloff found that the proportion of exemptions from the army for infirmity increased enormously from 26 per cent. in 1816-17, to 38 per cent. in 1826-27, declining later to 34 per cent. in 1860-64, though he is careful to point out that this result must not be entirely ascribed to the reversed selection of wars. There could, however, be no doubt that most kinds of infirmities became more frequent as a result of military selection. Lapouge's more recent investigation into the results of the Franco-Prussian war of 1870 were of similar character; when examining the recruits of 1892-93 he found that these "children of the war" were inferior to those born earlier, and that there was probably an undue proportion of defective individuals among their fathers. It cannot be said that these investigations finally demonstrate the evil results of war on the race. The subject is complicated, and some authorities, like Collignon in France and Ammon in Germany,—both, it may be well to note, army surgeons,—have sought to smooth down and explain away the dysgenic effects of war. But, on the whole, the facts seem to support those probabilities which the insight of Franklin first clearly set forth.
It is interesting in the light of these considerations on the eugenic bearings of warfare to turn for a moment to those who proclaim the high moral virtues of war as a national regenerator.
It is chiefly in Germany that, for more than a century past, this doctrine has been preached.10 "War invigorates humanity," said Hegel, "as storms preserve the sea from putrescence." "War is an integral part of God's Universe," said Moltke, "developing man's noblest attributes." "The condemnation of war," said Treitschke, "is not only absurd, it is immoral."11 These brave sayings scarcely bear calm and searching examination at the best, but, putting aside all loftier appeals to humanity or civilisation, a "national regenerator" which we have good reason to suppose enfeebles and deteriorates the race, cannot plausibly be put before us as a method of ennobling humanity or as a part of God's Universe, only to be condemned on pain of seeing a company of German professors pointing the finger to our appalling "Immorality," on their drill-sergeant's word of command.
At the same time, this glorification of the regenerating powers of war quite overlooks the consideration that the fighting spirit tends to destroy itself, so that the best way to breed good fighters is not to preach war, but to cultivate peace, which is what the Germans have, in actual practice, done for over forty years past. France, the most military, and the most gloriously military, nation of the Napoleonic era, is now the leader in anti-militarism, altogether indifferent to the lure of military glory, though behind no nation in courage or skill. Belgium has not fought for generations, and had only just introduced compulsory military service, yet the Belgians, from their King and their Cardinal-Archbishop downwards, threw themselves into the war with a high spirit scarcely paralleled in the world's history, and Belgian commercial travellers developed a rare military skill and audacity. All the world admires the bravery with which the Germans face death and the elaborate detail with which they organise battle, yet for all their perpetual glorification of war there is no sign that they fight with any more spirit than their enemies. Even if we were to feel ourselves bound to accept war as "an integral part of God's Universe," we need not trouble ourselves to glorify war, for, when once war presents itself as a terrible necessity, even the most peaceable of men are equal to the task.
This consideration brings us to those "moral equivalents of war" which William James was once concerned over, when he advocated, in place of military conscription, "a conscription of the whole youthful population to form for a certain number of years a part of the army enlisted against Nature."12 Such a method of formally organising in the cause of civilisation, instead of in the cause of savagery, the old military traditions of hardihood and discipline may well have its value. But the present war has shown us that in no case need we fear that these high qualities will perish in any vitally progressive civilisation. For they are qualities that lie in the heart of humanity itself. They are not created by the drill-sergeant; he merely utilises them for his own, as we may perhaps think, disastrous ends. This present war has shown us that on every hand, even in the unlikeliest places, all the virtues of war have been fostered by the cultivation of the arts and sciences of peace, ready to be transformed to warlike ends by men who never dreamed of war. In France we find many of the most promising young scientists, poets, and novelists cheerfully going forth to meet their death. On the other side, we find a Kreisler, created to be the joy of the world, ready to be trampled to death beneath the hoofs of Cossack horses. The friends of Gordon
