ALTERNATIVE SATISFACTIONS FOR THE FIGHTING EMOTIONS
The uniformity of visceral responses when almost any feelings grow
very intense, and under such conditions the identity of these
responses with those characteristically aroused in the belligerent
emotion of anger or rage and its counterpart, fear, offer interesting
possibilities of transformation and substitution. This is especially
true in the activities of human beings. And because men have devised
such terribly ingenious and destructive modes of expressing these
feelings in war, an inquiry into the basis for possible substitution
seems not out of place.
Support for the Militarist Estimate of the Strength of
the Fighting Emotions and Instincts
The business of killing and of avoiding death has been one of the
primary interests of living beings throughout their long history
on the earth. It is in the highest degree natural that feelings
of hostility often burn with fierce intensity, and then, with
astonishing suddenness, that all the powers of the body are called
into action--for the strength of the feelings and the quickness of
the response measure the chances of survival in a struggle where
the issue may be life or death. These are the powerful emotions
and the deeply ingrained instinctive reactions which invariably
precede combat. They are the emotions and instincts that sometimes
seize upon individuals in groups and spread like wildfire into
larger and larger aggregations of men, until vast populations are
shouting and clamoring for war. To whatever extent military plans
are successful in devising a vast machine for attack or defense, the
energies that make the machine go are found, in the last analysis,
in human beings who, when the time for action comes, are animated
by these surging elemental tendencies which assume control of their
conduct and send them madly into conflict.
The strength of the fighting instinct in man has been one of the
main arguments used by the militarists in support of preparation for
international strife. They point to the historical fact that even
among highly civilized peoples scarcely a decade passes without a
kindling of the martial emotions, which explode in actual warfare.
Such fighting, they say, is inevitable--the manifestation of
“biological law”--and, so long as human nature remains unchanged,
decision by battle must be resorted to. They urge, furthermore,
that in war and in the preparations for war important physical
qualities--sturdiness, hardihood, and strength for valorous
deeds--are given peculiarly favorable opportunities for development,
and that if these opportunities are lacking, lusty youth will give
place to weaklings and mollycoddles. In addition the militarists
say that war benefits mankind by its moral effects. Without war
nations become effete, their ideals become tarnished, the people
sink into self-indulgence, their wills weaken and soften in luxury.
War, on the contrary, disciplines character, it sobers men, it
teaches them to be brave and patient, it renews a true order of
values, and its demand for the supreme sacrifice of life brings
forth in thousands an eager response that is the crowning glory of
the human spirit. As the inevitable expression of a deep-rooted
instinct, therefore, and as a unique means of developing desirable
physical and moral qualities, war is claimed by the militarists to
be a natural necessity.[225]
The militarist contention that the fighting instinct is firmly fixed
in human nature receives strong confirmation in the results of our
researches. Survival has been decided by the grim law of mortal
conflict, and the mechanism for rendering the body more competent in
conflict has been revealed in earlier chapters as extraordinarily
perfect and complete. Moreover, the physiological provisions for
fierce struggle are found not only in the bodies of lower animals,
that must hunt and kill in order to live, but also in human beings.
Since this remarkable mechanism is present, and through countless
generations has served the fundamentally important purpose of giving
momentous aid in the struggle for existence, the militarists might
properly argue that, as with other physiological processes, bodily
harmony would be promoted by its exercise. Indeed, they might account
for the periodic outburst of belligerent feelings by assuming that
these natural aptitudes require occasional satisfaction.[*]
*[Footnote: Mr. Graham Wallas has made the interesting suggestion
(The Great Society, New York, 1914, p. 66) that nervous strain
and restlessness due to “baulked disposition” may result from the
absence of circumstances which would call the emotional responses
into action. And he cites Aristotle’s theory that pent passions
may be released by represented tragedy and by music.]
Growing Opposition to the Fighting Emotions and
Instincts as Displayed in War
In spite of the teachings of history that wars have not grown fewer,
and in spite of the militarist argument that war is a means of
purging mankind of its sordid vices, and renewing instead the noblest
virtues, the conclusion that the resort to arms is unavoidable and
desirable is nowadays being strongly contested. The militarists show
only part of the picture. No large acquaintance with the character
of warfare is necessary to prove that when elemental anger, hate
and fear prevail, civilized conventions are abandoned and the most
savage instincts determine conduct. Homes are looted and burned,
women and children are abominably treated, and many innocents are
murdered outright or starved to death. No bland argument for the
preservation of the manly virtues can palliate such barbarities.
Even when fighting men are held within the rules, the devices for
killing and injuring are now made so perfect by devilish ingenuity
that by the pulling of a trigger one man can in a few seconds mow
down scores of his fellow-creatures and send them writhing to agony
or death. War has become too horrible; it is conducted on too
stupendous a scale of carnage and expenditure; it destroys too many
of the treasured achievements of the race; it interferes too greatly
with consecrated efforts to benefit all mankind by discovery and
invention; it involves too much suffering among peoples not directly
concerned in the struggle; it is too vastly at variance with the
methods of fair dealing that have been established between man and
man; the human family has become too closely knit to allow some of
its members to bring upon themselves and all the rest poverty and
distress and a long heritage of bitter hatred and resolution to
seek revenge.
All these reasons for hostility to war imply a thwarting of strong
desires in men--desires for family happiness, devotion to beauty
and to scholarship, passion for social justice, hopes of lessening
poverty and disease. As was pointed out in the previous chapter,
the feeling of hostility has no definite object to awaken it. It is
roused when there is opposition to what we ardently wish to get.
And because war brings conditions which frustrate many kinds of
eagerly sought purposes, war has roused in men a hostility against
itself. There is then a war against war, a willingness to fight
against monstrous carnage and destruction, that grows in intensity
with every war that is waged.
The Desirability of Preserving the Martial Virtues
Although there is increasing opposition to the display of the
fighting emotions and instincts in war, nevertheless the admirable
moral and physical qualities, claimed by the militarists to be
the unique products of war, are too valuable to be lost. As
McDougall[226] has indicated, when the life of ideas becomes richer,
and the means we take to overcome obstructions to our efforts more
refined and complex, the instinct to fight ceases to express itself
in its crude natural manner, save when most intensely excited, and
becomes rather a source of increased energy of action towards the end
set by any other instinct; the energy of its impulses adds itself
to and reënforces that of other impulses and so helps us to overcome
our difficulties. In this lies its great value for civilized man. A
man devoid of the pugnacious instinct would not only be incapable
of anger, but would lack this great source of reserve energy which
is called into play in most of us by any difficulty in our path.
Thus the very efficiency of a war against war, as well as struggle
against other evils that beset civilized society, rests on the
preservation and use of aggressive feeling and the instinct to
attack. From this point of view the insistence by the militarists
that we must accept human nature as we find it, and that the attempt
to change it is foolish, seems a more justifiable attitude than
that of the pacifists who belittle the fighting qualities and urge
that changing them is a relatively simple process. We should not
wish them changed. Even if in the war against war a means should
be established of securing international justice, and if through
coöperative action the decrees of justice were enforced, so that
the occasions which would arouse belligerent emotions and instincts
were much reduced, there would still remain the need of recognizing
their elemental character and their possible usefulness to society.
What is needed is not a suppression of these capacities to feel and
act, but their diversion into other channels where they may have
satisfactory expression.
Moral Substitutes for Warfare
“We must make new energies and hardihoods continue the manliness
to which the military mind so faithfully clings. Martial virtues
must be the enduring cement; intrepidity, contempt of softness,
surrender of private interest, obedience to command, must still
remain the rock upon which states are built.” Thus wrote William
James[227] in proposing a “moral equivalent for war.” This, he
suggested, should consist of such required service in the hard
and difficult occupations as would take the childishness and
superciliousness out of our youth and give them soberer ideas and
healthier sympathies with their fellow-men. He conceived that by
proper direction of its education a people should become as proud
of the attainment by the nation of superiority in any ideal respect
as it would be if the nation were victorious in war. “The martial
type of character,” he declared, “can be bred without war. Strenuous
honor and disinterestedness abound elsewhere. Priests and medical
men are in a fashion educated to it, and we should all feel some
degree of it imperative if we were conscious of our work as an
obligatory service to the state. We should be _owned_, as soldiers
are by the army, and our pride would rise accordingly. We could
be poor, then, without humiliation, as army officers now are. The
only thing needed henceforth is to inflame the civic temper as
past history has inflamed the military temper.”
Similar ideas have been expressed by others.[228] It has been pointed
out that the great war of mankind is that against pain, disease,
poverty and sin; that the real heroes are not those who squander
human strength and courage in fighting one another, but those who
fight for man against these his eternal foes. War of man against
man, in this view, becomes dissension in the ranks, permitting the
common enemies to strike their most telling blows.
These moral considerations, however, are apart from the main intent
of our discussion. Our earlier inquiry confirmed the belief that the
fighting emotions are firmly rooted in our natures, and showed that
these emotions are intimately associated with provisions for physical
exertion. It is particularly in this aspect of the discussion of
substitutes for war that these studies have significance.
Physical Substitutes for Warfare
The idealization of the state and the devotion of service to social
welfare, which have been suggested as moral substitutes for military
loyalty, leave unanswered the claims of the militarists that in
war and in preparations for war opportunities are offered which
are peculiarly favorable to the development of important physical
qualities--bodily vigor, sturdiness, and ability to withstand all
manner of hardships.
In the evidence previously presented, it seems to me there was a
suggestion that offers a pertinent alternative to these claims.
When the body goes onto what we have called a war footing, the
physiological changes that suddenly occur are all adapted to the
putting forth of supreme muscular and nervous efforts. That was
what primitive battle consisted of, through countless myriads of
generations--a fierce physical contest of beast with beast, and of
man with man. Such contests, attended as they were by the thrill
of unpredictable incidents, and satisfying completely the lust of
combat, are to be contrasted with the dull grind in preparation
for modern war, the monotonous regularity of subservience, the
substitution everywhere of mechanism for muscle, and often the
attack on an enemy who lies wholly unseen.[*] As Wallas with nice
irony has remarked, “The gods in Valhalla would hardly choose the
organization of modern lines of military communication, as they chose
the play of sword and spear, to be the most exquisite employment
of eternity.”
*[Footnote: Lord Wolseley, while commander-in-chief of the English
forces, in 1897, secured sanction for not displaying the regimental
colors in battle. “It would be madness and a crime,” he declared,
“to order any soldier to carry colors into action in the future.
You might quite as well order him to be assassinated. We have
had most reluctantly to abandon a practice to which we attached
great importance, and which, under past and gone conditions of
fighting, was invaluable in keeping alive the regimental spirit
upon which our British troops depended so much.” All war has been
transformed by the invention of the far-reaching and fate-dealing
rifle and automatic gun, with which an enemy kills, whose face is
not even seen. War is almost reduced to a mechanical interchange
of volleys and salvoes, and to the intermittent fire of rifles
and machine guns, with short rushes at the last, in which there
is no place for the dignity and grace of the antique battle of
the standard. (See London Times, July 31, 1897, p. 12.)
T. F. Millard, the well-known correspondent of the Russo-Japanese
War, wrote as follows of the characteristics of present day
conflicts: “A large part of modern war is on too great a scale
to give much opportunity for individual initiative. Soldiers can
rarely tell what is going on in their immediate vicinity. They
cannot always see the enemy they are firing at, and where they can
see the object of their fire such an important matter as range
and even direction cannot be left to them.... Troops are clothed
so much alike nowadays that it is very difficult to distinguish
friend from foe at five hundred yards, and large bodies of troops
rarely get that close to each other in modern war while there is
light enough to see clearly.... Battery officers simply see that
their guns are handled according to instructions. They regulate
the time, speed, objective and range as ordered.... The effects
of the fire are observed by officers appointed to that duty,
stationed at various parts of the field, often miles and miles
apart, and who are in constant communication with the chief of
artillery by telephone.” (See Scribner’s Magazine, 1905, xxxvii,
pp. 64, 66.)
The testimony of a captain of a German battery engaged against
the French and English in 1914, supports the foregoing claims.
He is reported as saying: “We shoot over those tree tops yonder
in accordance with directions for range and distance which come
from somewhere else over a field telephone, but we never see the
men at whom we are firing. They fire back without seeing us, and
sometimes their shells fall short or go beyond us, and sometimes
they fall among us and kill and wound a few of us. Thus it goes
on day after day. I have not with my own eyes seen a Frenchman
or an Englishman unless he was a prisoner. It is not so much
pleasure--fighting like this.” (See Philadelphia Saturday Evening
Post, December 26, 1914, p. 27.)]
While it is true that physical strength can be developed by any
form of hard labor, as, for example, by sawing wood or digging
ditches, such labor does not stimulate quickness, alertness, and
resourcefulness in bodily action. Nor does it give any occasion for
use of the emotional mechanism for reënforcement. If this mechanism,
like other physiological arrangements, is present in the body for
use--and previous discussion leaves little doubt of that--then as
a means of exercising it and, in addition, satisfying the strong
instinct for competitive testing of strength and physical skill,
some activity more enlivening than monotonous gymnastics and ordered
marching is required.
In many respects strenuous athletic rivalries present, better than
modern military service, the conditions for which the militarists
argue, the conditions for which the body spontaneously prepares
when the passion for fighting prevails. As explained in an
earlier chapter, in competitive sports the elemental factors are
retained--man is again pitted against man, and all the resources
of the body are summoned in the eager struggle for victory. And
because, under such circumstances, the same physiological alterations
occur that occur in anticipation of mortal combat, the belligerent
emotions and instincts, so far as their bodily manifestations are
concerned, are thereby given complete satisfaction.
The Significance of International Athletic Competitions
For reasons given above, I venture to lay emphasis on a suggestion,
which has been made before by others, that the promotion of great
international athletic contests, such as the Olympic games, would
do for our young men much that is now claimed as peculiar to the
values of military discipline. The substitution of athletic rivalries
for battle is not unknown. In the Philippine Islands, according
to Worcester,[229] there were no athletics before the American
occupation. The natives soon learned games from the soldiers. And
when the sports reached such development that competition between
towns and provinces was possible, they began to arouse the liveliest
enthusiasm among the people. The physical development of the
participants has been greatly stimulated, the spirit of fair play
and sportsmanship, formerly lacking, has sprung into existence in
every section of the Islands, and the annual meets between athletic
teams from various provinces are recognized as promoting a general
and friendly understanding among the different Filipino tribes. The
fierce Igarots of Bontoc, once constantly at war with neighboring
tribes, now show their prowess not in head-hunting, but in baseball,
wrestling, and the tug-of-war.[*]
*[Footnote: It is reported that when these warriors first appeared
at the games, each brought his spear, which he drove into the
ground beside him, ready for use. As the nature of the new
rivalries became known, the spears were left behind.]
Is it unreasonable to expect that what has happened in the Philippine
Islands might, by proper education and suggestion, happen elsewhere
in the world? Certainly the interest in athletic contests is no
slight and transient interest. At the time of a great war we know
that news of the games is fully as much demanded as news of the
war. Already in the United States, without special stimulation, the
number of young men engaged in athletic training is estimated as
equal to the number in the standing army. And in England, belief
in the efficacy of athletics as a means of promoting hardihood
and readiness to face stern hazards has found expression in the
phrase that England’s battles have been won on the football fields
of Rugby and of Eton. With the further promotion of international
contests the influence of competitive sports is likely to increase
rather than lessen. Within national boundaries emulation is sure
to stimulate extensively such games as will bring forth the best
representative athletes that the country can produce. In one of
the high-spirited European nations, which made a poor showing at
the last Olympic meet, thousands of young men began training for
the next meet, under a director imported from the nation that had
made the highest records.
Training for athletic contests is quite as likely to enure young
men to physical hardship and fatigue, is quite as conducive to
the development of bodily vigor, the attainment of alertness and
skill and the practice of self-restraint, as is army life with its
traditional associations and easy license. It may be urged, however,
that an essential element is lacking in all this discussion--the
sobering possibility that in war the supreme surrender of life itself
may be required. Death for one’s country is indeed glorious. But the
argument that being killed is desirable has little to commend it.
When the strongest and sturdiest are constantly chosen to be fed to
the engines of annihilation, the race is more likely to lose greater
values than it gains from the spectacle of self-sacrifice, however
perfect that may be. Are there not advantages in the conditions of
great athletic rivalries that may compensate for war’s most austere
demand? The race of hardy men, to secure which the militarists urge
war, is much more likely to result from the honoring and preserving
of vigorous men in their vigor than it is from the systematic
selection of such men to be destroyed in their youth.
There are other aspects of international games which strongly commend
them as an alternative to the pursuit of military discipline.
The high standards of honor and fairness in sport; its unfailing
revelation of excellence without distinctions of class, wealth,
race or color; the ease with which it becomes an expression of
the natural feelings of patriotism; the respect which victory and
pluckily borne defeat inspire in competitors and spectators alike;
the extension of acquaintance and understanding which follows from
friendly and magnanimous rivalry among strong men who come together
from the ends of the earth--each of these admirable features of
athletic contests between nations might be enlarged upon. But, as
intimated before, these moral considerations must be left without
further mention, as being irrelevant to the physiological processes
with which we are dealing.
We are concerned with the question of exercising the fighting
instinct and thus assuring the physical welfare of the race. The
race must degenerate, the militarists say, if this instinct is not
allowed to express itself in war. This declaration we are in a
position to deny, for the evidence is perfectly clean-cut that the
aggressive instincts, which through æons of racial experience have
naturally and spontaneously developed vigor and resourcefulness in
the body, are invited by elemental emotions, and that through these
emotions energies are released which are highly useful to great
physical effort. No stupid routine of drill, or any other deadening
procedure, will call these energizing mechanisms into activity. War
and the preparations for war nowadays have become too machine-like
to serve as the best means of preserving and disciplining these
forces. The exhilarating swing and tug and quick thrust of the big
limb muscles have largely vanished. Pressing an electric contact or
bending the trigger finger is a movement altogether too trifling.
If, then, natural feelings must be expressed, if the fighting
functions of the body must be exercised, how much better that these
satisfactions be found in natural rather than in artificial actions,
how much more reasonable that men should struggle for victory in
the ancient ways, one against another, body and spirit, as in the
great games.

often used in the printed work, or failing that the more usual form
in general use at the time of publication. No typographical change
has been made within direct quotes from other works.
4. Page 25: "or thoradico-lumbar division" has been changed to "or
thoracico-lumbar division".
5. Page 58: The name "Emden" in "Emden and v. Furth" has been
changed to "Embden" in agreement with Footnote 1 on Page 65. (Gustav
Embden, 1874-1933.)
6. Page 62: The Greek letter Β (Beta) has been substituted for
Latin B at the start of "Β-tetrahydronaphthylamine".
