CHAPTER XVI

WAR

War always changes the composition of a nation; but this change may be

either a loss or a gain. The modification of selection by war is far

more manifold than the literature on the biological effects of war would

lead the reader to suppose. All wars are partly eugenic and partly

dysgenic; some are mainly the one, some are mainly the other. The racial

effects of war occur in at least three periods:

1. The period of preparation.

2. The period of actual fighting.

3. The period of readjustment after the war.

The first division involves the effect of a standing army, which

withdraws men during a part of the reproductive period and keeps most of

them in a celibate career. The officers marry late if at all and show a

very low birth-rate. The prolonged celibacy has in many armies led to a

higher incidence of venereal diseases which prolongs the celibacy and

lowers the birthrate.[155] Without extended discussion, the following

considerations may be named as among those which should govern a policy

of military preparedness that will safeguard, as far as possible, the

eugenic interests:

1. If the army is a standing one, composed of men serving long terms of

enlistment, they should be of as advanced an age as is compatible with

military efficiency. If a man of 35 has not married, it is probable that

he will never marry, and therefore there is less loss to the race in

enrolling him for military service, than is the case with a man of

20-25.

2. The army (except in so far as composed of inferior men) should not

foster celibacy. Short enlistments are probably the most valuable means

of avoiding this evil.

3. Universal conscription is much better than voluntary service, since

the latter is highly selective, the former much less so. Those in

regular attendance in college should receive their military training in

their course as is now done.

4. Officers' families should be given an additional allowance for each

child. This would aid in increasing the birth-rate, which appears to be

very low among army and navy officers in the United States service, and

probably in that of all civilized countries.

5. Every citizen owes service to his nation, in time of need, but

fighting service should not be exacted if some one else could perform it

better than he where he is expert in some other needed field. The recent

action of England in sending to the front as subaltern officers, who

were speedily killed, many highly trained technicians and young

scientists and medical men who would have been much more valuable at

home in connection with war measures, is an example of this mistake.

Carrying the idea farther, one sees that in many nations there are

certain races which are more valuable on the firing line than in

industries at the rear; and it appears that they should play the part

for which they are best fitted. From this point of view, the Entente

allies were wholly justified in employing their Asiatic and African

subjects in war. In the United States are millions of negroes who are of

less value than white men in organized industry but almost as valuable

as the whites, when properly led, at the front. It would appear to be

sound statesmanship to enlist as many Negroes as possible in the active

forces, in case of war, thus releasing a corresponding number of more

skilled white workers for the industrial machine on whose efficiency

success in modern warfare largely rests.

The creation of the National Army in the United States, in 1917, while

in most ways admirably conducted, was open to criticism in several

respects, from the eugenic point of view:

(a) Too many college men and men in intellectual pursuits were taken as

officers, particularly in the aviation corps. There should have been

more men employed as officers who had demonstrated the necessary

qualifications, as foremen and others accustomed to boss gangs of men.

(b) The burden was thrown too heavily on the old white Americans, by the

exemption of aliens, who make up a large part of the population in some

states. There were communities in New England which actually could not

fill their quotas, even by taking every acceptable native-born resident,

so large is their alien population. The quota should have been adjusted

if aliens were to be exempt.

(c) The district boards were not as liberal as was desirable, in

exempting from the first quota men needed in skilled work at home. The

spirit of the _selective_ draft was widely violated, and necessitated a

complete change of method before the second quota was called by the much

improved questionnaire method.

It is difficult to get such mistakes as these corrected; nevertheless a

nation should never lose sight of the fact that war is inevitably

damaging, and that the most successful nation is the one which wins its

wars with the least possible eugenic loss.

Leaving the period of preparedness, we consider the period of open

warfare. The reader will remember that, in an earlier chapter, we

divided natural selection into (1) lethal, that which operates through

differential mortality; (2) sexual, that which operates through

differential mating; and (3) fecundal, that which operates through

differential fecundity. Again, selection operates both in an inter-group

competition and an intra-group competition. The influence of any agency

on natural selection must be examined under each of these six heads. In

the case of war, however, fecundal selection may be eliminated, as it is

little influenced. Still another division arises from the fact that the

action of selection is different during war upon the armed forces

themselves and upon the population at home; and after the war, upon the

nations with the various modifications that the war has left.

We will consider lethal selection first. To measure the effect of the

inter-group selection of the armed forces, one must compare the

relative quality of the two races involved. The evidence for believing

in substantial differences between races is based (a) upon their

relative achievement when each is isolated, (b) upon the relative rank

when the two are competing in one society, and (c) upon the relative

number of original contributions to civilization each has made. Such

comparisons are fatal to the sentimental equalitarianism that denies

race differences. While there is, of course, a great deal of

overlapping, there are, nevertheless, real average differences. To think

otherwise is to discard evolution and revert to the older standpoint of

"special creation."

Comparison of the quality of the two sides is sometimes, of course, very

difficult. One may feel little hesitation in giving a decision in the

classical war of the Greeks and Persians, or the more modern case of the

English and Afghans, but when considering the Franco-Prussian war, or

the Russo-Japanese war, or the Boer war, or the American civil war, it

is largely a matter of mere opinion, and perhaps an advantage can hardly

be conceded to either side. Those who, misunderstanding the doctrine of

evolution, adhere to the so-called "philosophy of force," would answer

without hesitation that the side which won was, _ipso facto_, the better

side. But such a judgment is based on numerous fallacies, and can not be

indorsed in the sweeping way it is uttered. Take a concrete example:

"In 1806, Prussia was defeated at the battle of Jena. According to the

philosophy of force, this was because Prussia was 'inferior' and France

was 'superior.' Suppose we admit for the moment that this was the case.

The selection now represents the survival of the fittest, the selection

which perfects the human species. But what shall we say of the battle of

Leipsic? At Leipsic, in 1813, all the values were reversed; it is now

France which is the 'inferior' nation.... Furthermore, a large number of

the same generals and soldiers who took part in the battle of Jena also

took part in the battle of Leipsic. Napoleon belonged, therefore, to a

race which was superior to that of Blücher in 1806, but to an inferior

race in 1813, in spite of the fact that they were the same persons and

had not changed their nationality. As soon as we bring these assertions

to the touchstone of concrete reality we see at once how untenable and

even ridiculous are direct biological comparisons."[156]

Without going into further detail, it is readily seen that, on the world

at large, the eugenic effect of a war would be very different according

as the sides differ much or little. Yet this difference in quality,

however great, will have no significance, unless the superior or

inferior side is in general more likely to lose fewer men. Where the

difference has been considerable, as between a civilized and savage

nation, it has been seldom that the superior has not triumphed with

fewer losses. Victory, however, is influenced much less in these later

days by the relative military efficiency of two single nations than by

their success in making powerful alliances. But such alignments are by

no means always associated with better quality, because (a) there is a

natural tendency for the weak to unite against a strong nation, (b) to

side with a group which is apparently succeeding, and (c) the alliances

may be the work of one or a few individuals who happen to be in

positions of power at the critical time.

Modern European wars, especially the latest one, have been marked by the

high quality of the combatants on both sides relative to the rest of the

world. As these same races fight with pertinacity, there is a high

mortality rate, so that the dysgenic result of these wars is

particularly deplorable.

As for the selection taking place _within_ each of the struggling

nations, the combatants and the non-combatants of the same age and sex

must first be compared. The difference here depends largely on how the

army in question was raised. Where the army is a permanent, paid force,

it probably does not represent a quality above the average of the

nation, except physically. When it is conscripted, it is superior

physically and probably slightly in other respects. If it is a

volunteer army, its quality depends largely on whether the cause being

fought for is one that appeals merely to the spirit of adventure or one

that appeals to some moral principle. In the latter case, the quality

may be such that the loss of a large part of the army will be peculiarly

damaging to the progress of the race. This situation is more common than

might be supposed, for by skillful diplomacy and journalism a cause

which may be really questionable is presented to the public in a most

idealistic light. But here, again, one can not always apply sweeping

generalizations to individual cases. It might be supposed, for instance,

that in the Confederate army the best eugenic quality was represented by

the volunteers, the second best by those who stayed out until they were

conscripted, and the poorest by the deserters. Yet David Starr Jordan

and Harvey Ernest Jordan, who investigated the case with care, found

that this was hardly true and that, due to the peculiar circumstances,

the deserters were probably not as a class eugenically inferior to the

volunteers.[157] Again some wars, such as that between the United States

and Spain, probably develop a volunteer army made up largely of the

adventurous, the nomadic, and those who have fewer ties; it would be

difficult to demonstrate that they are superior to those who, having

settled positions at home, or family obligations, fail to volunteer. The

greatest damage appears to be done in such wars as those waged by great

European nations, where the whole able-bodied male population is called

out, and only those left at home who are physically or mentally unfit

for fighting--but not, it appears to be thought, unfit to perpetuate the

race.

Even within the army of one side, lethal selection is operative. Those

who are killed are by no means a haphazard sample of the whole army.

Among the victims there is a disproportionate representation of those

with (1) dauntless bravery, (2) recklessness, (3) stupidity. These

qualities merge into each other, yet in their extremes they are widely

different. However, as the nature of warfare changes with the increase

of artillery, mines, bombs, and gases, and decrease of personal combat,

those who fall are more and more chance victims.

In addition to the killed and mortally wounded, there are many deaths

from disease or from wounds which were not necessarily fatal. Probably

the most selective of any of these three agencies is the variable

resistance to disease and infection and the widely varying knowledge and

appreciation of the need for hygienic living shown by the individual,

as, for instance, by less reckless drinking of unsterilized water. But

here, too, in modern warfare, this item is becoming less selective, with

the advance in discipline and in organized sanitation.

The efficiency of selection will be affected by the percentage that each

side has sent to the front, if the combatants are either above or below

the average of the population. A nation that sends all its able-bodied

males forward will be affected differently from its enemy that has

needed to call upon only one-half of its able-bodied men in order to win

its cause.

Away from the fighting lines of the contending sides, conditions that

prevail are rendered more severe in many ways than in times of peace.

Poverty becomes rife, and sanitation and medical treatment are commonly

sacrificed under the strain. During a war, that mitigation of the action

of natural selection which is so common now among civilized nations, is

somewhat less effective than in times of peace. The scourge of typhus in

Serbia is a recent and graphic illustration.

After a war has been concluded, certain new agencies of inter-group

selection arise. The result depends largely on whether the vanquished

have had a superior culture brought to them, as in the case of the

Philippines, or whether, on the contrary, certain diseases have been

introduced, as to the natives of the New World by the Spanish conquerors

and explorers, or crushing tribute has been levied, or grievous

oppression such as has befallen Belgium.

Sometimes the conquerors themselves have suffered severely as the result

of excessive spoliation, which has produced vicious idleness and

luxurious indulgence, with the ultimate effect of diminishing the

birth-rate.

Within the nation there may be various results. Sometimes, by the

reduction of overcrowding, natural selection will be less severe. On the

other hand, the loss of that part of the population which is more

economically productive is a very serious loss, leading to excessive

poverty with increased severity in the action of natural selection, of

which some of the Southern States, during the Reconstruction period,

offer a good illustration.

Selection is also rendered more intense by the heavy burden of taxation,

and in the very common depreciation of currency as is now felt in

Russia.

Sexual selection as well as lethal is affected by war in manifold ways.

Considering the armed force, there is an inter-group selection, when the

enemy's women are assaulted by the soldiers. While this has been an

important factor in the past, it is somewhat less common now, with

better army discipline and higher social ideals.

Within the group, mating at the outset of a war is greatly increased by

many hurried marriages. There is also alleged to be sometimes an

increase of illegitimacy in the neighborhood of training camps. In each

of these instances, these matings do not represent as much maturity of

judgment as there would have been in times of peace, and hence give a

less desirable sexual selection.

In the belligerent nation at home, the number of marriageable males is

of course far less than at ordinary times. It becomes important, then,

to compare the quality of the non-combatants and those combatants who

survive and return home, since their absence during the war period of

course decreases their reproduction as compared with the non-combatants.

The marked excess of women over men, both during the war and after,

necessarily intensifies the selection of women and proportionately

reduces that of men, since relatively fewer men will remain unmated.

This excess of women is found in all classes. Among superiors there are,

in addition, some women who never marry because the war has so reduced

the number of suitors thought eligible.

The five years' war of Paraguay with Brazil, Uruguay and Argentina

(1864-1869) is perhaps the most glaring case on record[158] in recent

years of the destruction of the male population of a country. Whole

regiments were made up of boys of 16 or less. At the beginning of the

war the population of Paraguay had been given as 1,337,437. It fell to

221,709 (28,746 men, 106,254 women, 86,079 children); it is even now

probably not more than half of the estimate made at the beginning of the

war. "Here in a small area has occurred a drastic case of racial ravage

without parallel since the time of the Thirty Years' War." Macedonia,

however, furnishes a fairly close parallel--D. S. Jordan found whole

villages there in 1913 in which not a single man remained: only women

and children. Conditions were not so very much better in parts of the

South at the close of the Civil War, particularly in Virginia and North

Carolina, where probably 40% of the young men of reproductive age died

without issue. And in a few of the Northern states, such as Vermont,

Connecticut and Massachusetts, the loss was proportionately almost as

great. These were probably as good men as any country has produced, and

their loss, with that of their potential offspring, undoubtedly is

causing more far-reaching effects in the subsequent history of the

United States than has ever been realized.

In the past and still among many savage peoples, inter-group selection

has been affected by the stealing of women from the vanquished. The

effect of this has been very different, depending on whether these women

would otherwise have been killed or spared, and also depending on the

relative quality of their nation to that of their conquerors.

To sum up, there are so many features of natural selection, each of

which must be separately weighed and the whole then balanced, that it is

a matter of extensive inquiry to determine whether a certain war has a

preponderance of eugenic or dysgenic results.

When the quality of the combatants is so high, compared with the rest

of the world, as during the Great War, no conceivable eugenic gains from

the war can offset the losses. It is probably well within the facts to

assume that the period of this war represents a decline in inherent

human quality, greater than in any similar length of time in the

previous history of the world.

Unfortunately, it does not appear that war is becoming much less common

if we consider number of combatants rather than number of wars as times

goes on,[159] and it steadily tends to be more destructive. War, then,

offers one of the greatest problems which the eugenist must face, for a

few months of war may undo all that eugenic reforms can gain in a

generation.

The total abolition of war would, of course, be the ideal, but there is

no possibility of this in the near future. The fighting instinct, it

must be remembered, is one of the most primitive and powerful that the

human mechanism contains. It was evolved in great intensity, to give man

supremacy over his environment--for the great "struggle for existence"

is with the environment, not with members of one's own species. Man long

ago conquered the environment so successfully that he has never since

had to exert himself in physical combat in this direction; but the

fighting instinct remained and could not be baulked without causing

uneasiness. Spurred on by a complex set of psychological and economic

stimuli, man took to fighting his own kind, to a degree that no other

species shows.

Now contrary to what the militarist philosophers affirm, this particular

sort of "struggle for existence" is not a necessity to the further

progressive evolution of the race. On the contrary it more frequently

reverses evolution and makes the race go backward, rather than forward.

The struggle for existence which makes the race progress is principally

that of the species with its environment, not that of some members of

the species with others. If the latter struggle could be supplanted by

the former then racial evolution would go ahead steadily without the

continuous reversals that warfare now gives.

William James saw, we believe, the true solution of the problem of

militarism, when he wrote his famous essay on _The Moral Equivalent of

War_. Here is man, full of fighting instinct which will not be baulked.

What is he to do? Professor James suggested that the youth of the nation

be conscripted to fight the environment, thus getting the fight "out of

its system" and rendering a real service to the race by constructive

reclamation work, instead of slaying each other and thus turning the

hands of the evolutionary clock backward.

When education has given everyone the evolutionary and eugenic view of

man as a species adapted to his environment, it may be possible to work

out some such solution as this of James. The only immediate course of

action open seems to be to seek, if possible, to diminish the frequency

of war by subduing nations which start wars and, by the organization of

a League to Enforce Peace; to avoid war-provoking conquests; to diminish

as much as possible the disastrous effects of war when it does come, and

to work for the progress of science and the diffusion of knowledge which

will eventually make possible the greater step, effective international

organization.
