Mutual Aid: A Factor of Evolution
Peter Kropotkin
INTRODUCTION
Two aspects of animal life impressed me most during the
journeys which I made in my youth in Eastern Siberia and Northern
Manchuria. One of them was the extreme severity of the struggle for
existence which most species of animals have to carry on against an
inclement Nature; the enormous destruction of life which
periodically results from natural agencies; and the consequent
paucity of life over the vast territory which fell under my
observation. And the other was, that even in those few spots where
animal life teemed in abundance, I failed to find—although I was
eagerly looking for it—that bitter struggle for the means of
existence, among animals belonging to the same species, which was
considered by most Darwinists (though not always by Darwin himself)
as the dominant characteristic of struggle for life, and the main
factor of evolution.The terrible snow-storms which sweep over the northern
portion of Eurasia in the later part of the winter, and the glazed
frost that often follows them; the frosts and the snow-storms which
return every year in the second half of May, when the trees are
already in full blossom and insect life swarms everywhere; the
early frosts and, occasionally, the heavy snowfalls in July and
August, which suddenly destroy myriads of insects, as well as the
second broods of the birds in the prairies; the torrential rains,
due to the monsoons, which fall in more temperate regions in August
and September—resulting in inundations on a scale which is only
known in America and in Eastern Asia, and swamping, on the
plateaus, areas as wide as European States; and finally, the heavy
snowfalls, early in October, which eventually render a territory as
large as France and Germany, absolutely impracticable for
ruminants, and destroy them by the thousand—these were the
conditions under which I saw animal life struggling in Northern
Asia. They made me realize at an early date the overwhelming
importance in Nature of what Darwin described as "the natural
checks to over-multiplication," in comparison to the struggle
between individuals of the same species for the means of
subsistence, which may go on here and there, to some limited
extent, but never attains the importance of the former. Paucity of
life, under-population—not over-population—being the distinctive
feature of that immense part of the globe which we name Northern
Asia, I conceived since then serious doubts—which subsequent study
has only confirmed—as to the reality of that fearful competition
for food and life within each species, which was an article of
faith with most Darwinists, and, consequently, as to the dominant
part which this sort of competition was supposed to play in the
evolution of new species.On the other hand, wherever I saw animal life in abundance,
as, for instance, on the lakes where scores of species and millions
of individuals came together to rear their progeny; in the colonies
of rodents; in the migrations of birds which took place at that
time on a truly American scale along the Usuri; and especially in a
migration of fallow-deer which I witnessed on the Amur, and during
which scores of thousands of these intelligent animals came
together from an immense territory, flying before the coming deep
snow, in order to cross the Amur where it is narrowest—in all these
scenes of animal life which passed before my eyes, I saw Mutual Aid
and Mutual Support carried on to an extent which made me suspect in
it a feature of the greatest importance for the maintenance of
life, the preservation of each species, and its further
evolution.And finally, I saw among the semi-wild cattle and horses in
Transbaikalia, among the wild ruminants everywhere, the squirrels,
and so on, that when animals have to struggle against scarcity of
food, in consequence of one of the above-mentioned causes, the
whole of that portion of the species which is affected by the
calamity, comes out of the ordeal so much impoverished in vigour
and health, that no progressive evolution of the species can be
based upon such periods of keen competition.Consequently, when my attention was drawn, later on, to the
relations between Darwinism and Sociology, I could agree with none
of the works and pamphlets that had been written upon this
important subject. They all endeavoured to prove that Man, owing to
his higher intelligence and knowledge, may mitigate the harshness
of the struggle for life between men; but they all recognized at
the same time that the struggle for the means of existence, of
every animal against all its congeners, and of every man against
all other men, was "a law of Nature." This view, however, I could
not accept, because I was persuaded that to admit a pitiless inner
war for life within each species, and to see in that war a
condition of progress, was to admit something which not only had
not yet been proved, but also lacked confirmation from direct
observation.On the contrary, a lecture "On the Law of Mutual Aid," which
was delivered at a Russian Congress of Naturalists, in January
1880, by the well-known zoologist, Professor Kessler, the then Dean
of the St. Petersburg University, struck me as throwing a new light
on the whole subject. Kessler's idea was, that besides the law of
Mutual Struggle there is in Nature the law of Mutual Aid, which,
for the success of the struggle for life, and especially for the
progressive evolution of the species, is far more important than
the law of mutual contest. This suggestion—which was, in reality,
nothing but a further development of the ideas expressed by Darwin
himself in The Descent of Man—seemed to me so correct and of so
great an importance, that since I became acquainted with it (in
1883) I began to collect materials for further developing the idea,
which Kessler had only cursorily sketched in his lecture, but had
not lived to develop. He died in 1881.In one point only I could not entirely endorse Kessler's
views. Kessler alluded to "parental feeling" and care for progeny
(see below, Chapter I) as to the source of mutual inclinations in
animals. However, to determine how far these two feelings have
really been at work in the evolution of sociable instincts, and how
far other instincts have been at work in the same direction, seems
to me a quite distinct and a very wide question, which we hardly
can discuss yet. It will be only after we have well established the
facts of mutual aid in different classes of animals, and their
importance for evolution, that we shall be able to study what
belongs in the evolution of sociable feelings, to parental
feelings, and what to sociability proper—the latter having
evidently its origin at the earliest stages of the evolution of the
animal world, perhaps even at the "colony-stages." I consequently
directed my chief attention to establishing first of all, the
importance of the Mutual Aid factor of evolution, leaving to
ulterior research the task of discovering the origin of the Mutual
Aid instinct in Nature.The importance of the Mutual Aid factor—"if its generality
could only be demonstrated"—did not escape the naturalist's genius
so manifest in Goethe. When Eckermann told once to Goethe—it was in
1827—that two little wren-fledglings, which had run away from him,
were found by him next day in the nest of robin redbreasts
(Rothkehlchen), which fed the little ones, together with their own
youngsters, Goethe grew quite excited about this fact. He saw in it
a confirmation of his pantheistic views, and said:—"If it be true
that this feeding of a stranger goes through all Nature as
something having the character of a general law—then many an enigma
would be solved." He returned to this matter on the next day, and
most earnestly entreated Eckermann (who was, as is known, a
zoologist) to make a special study of the subject, adding that he
would surely come "to quite invaluable treasuries of results"
(Gespräche, edition of 1848, vol. iii. pp. 219, 221).
Unfortunately, this study was never made, although it is very
possible that Brehm, who has accumulated in his works such rich
materials relative to mutual aid among animals, might have been
inspired by Goethe's remark.Several works of importance were published in the years
1872-1886, dealing with the intelligence and the mental life of
animals (they are mentioned in a footnote in Chapter I of this
book), and three of them dealt more especially with the subject
under consideration; namely, Les Societes animales, by Espinas
(Paris, 1877); La Lutte pour l'existence et l'association pout la
lutte, a lecture by J.L. Lanessan (April 1881); and Louis Buchner's
book, Liebe und Liebes-Leben in der Thierwelt, of which the first
edition appeared in 1882 or 1883, and a second, much enlarged, in
1885. But excellent though each of these works is, they leave ample
room for a work in which Mutual Aid would be considered, not only
as an argument in favour of a pre-human origin of moral instincts,
but also as a law of Nature and a factor of evolution. Espinas
devoted his main attention to such animal societies (ants, bees) as
are established upon a physiological division of labour, and though
his work is full of admirable hints in all possible directions, it
was written at a time when the evolution of human societies could
not yet be treated with the knowledge we now possess. Lanessan's
lecture has more the character of a brilliantly laid-out general
plan of a work, in which mutual support would be dealt with,
beginning with rocks in the sea, and then passing in review the
world of plants, of animals and men. As to Buchner's work,
suggestive though it is and rich in facts, I could not agree with
its leading idea. The book begins with a hymn to Love, and nearly
all its illustrations are intended to prove the existence of love
and sympathy among animals. However, to reduce animal sociability
to love and sympathy means to reduce its generality and its
importance, just as human ethics based upon love and personal
sympathy only have contributed to narrow the comprehension of the
moral feeling as a whole. It is not love to my neighbour—whom I
often do not know at all—which induces me to seize a pail of water
and to rush towards his house when I see it on fire; it is a far
wider, even though more vague feeling or instinct of human
solidarity and sociability which moves me. So it is also with
animals. It is not love, and not even sympathy (understood in its
proper sense) which induces a herd of ruminants or of horses to
form a ring in order to resist an attack of wolves; not love which
induces wolves to form a pack for hunting; not love which induces
kittens or lambs to play, or a dozen of species of young birds to
spend their days together in the autumn; and it is neither love nor
personal sympathy which induces many thousand fallow-deer scattered
over a territory as large as France to form into a score of
separate herds, all marching towards a given spot, in order to
cross there a river. It is a feeling infinitely wider than love or
personal sympathy—an instinct that has been slowly developed among
animals and men in the course of an extremely long evolution, and
which has taught animals and men alike the force they can borrow
from the practice of mutual aid and support, and the joys they can
find in social life.The importance of this distinction will be easily appreciated
by the student of animal psychology, and the more so by the student
of human ethics. Love, sympathy and self-sacrifice certainly play
an immense part in the progressive development of our moral
feelings. But it is not love and not even sympathy upon which
Society is based in mankind. It is the conscience—be it only at the
stage of an instinct—of human solidarity. It is the unconscious
recognition of the force that is borrowed by each man from the
practice of mutual aid; of the close dependency of every one's
happiness upon the happiness of all; and of the sense of justice,
or equity, which brings the individual to consider the rights of
every other individual as equal to his own. Upon this broad and
necessary foundation the still higher moral feelings are developed.
But this subject lies outside the scope of the present work, and I
shall only indicate here a lecture, "Justice and Morality" which I
delivered in reply to Huxley's Ethics, and in which the subject has
been treated at some length.Consequently I thought that a book, written on Mutual Aid as
a Law of Nature and a factor of evolution, might fill an important
gap. When Huxley issued, in 1888, his "Struggle-for-life" manifesto
(Struggle for Existence and its Bearing upon Man), which to my
appreciation was a very incorrect representation of the facts of
Nature, as one sees them in the bush and in the forest, I
communicated with the editor of the Nineteenth Century, asking him
whether he would give the hospitality of his review to an elaborate
reply to the views of one of the most prominent Darwinists; and Mr.
James Knowles received the proposal with fullest sympathy. I also
spoke of it to W. Bates. "Yes, certainly; that is true Darwinism,"
was his reply. "It is horrible what 'they' have made of Darwin.
Write these articles, and when they are printed, I will write to
you a letter which you may publish." Unfortunately, it took me
nearly seven years to write these articles, and when the last was
published, Bates was no longer living.After having discussed the importance of mutual aid in
various classes of animals, I was evidently bound to discuss the
importance of the same factor in the evolution of Man. This was the
more necessary as there are a number of evolutionists who may not
refuse to admit the importance of mutual aid among animals, but
who, like Herbert Spencer, will refuse to admit it for Man. For
primitive Man—they maintain—war of each against all was the law of
life. In how far this assertion, which has been too willingly
repeated, without sufficient criticism, since the times of Hobbes,
is supported by what we know about the early phases of human
development, is discussed in the chapters given to the Savages and
the Barbarians.The number and importance of mutual-aid institutions which
were developed by the creative genius of the savage and half-savage
masses, during the earliest clan-period of mankind and still more
during the next village-community period, and the immense influence
which these early institutions have exercised upon the subsequent
development of mankind, down to the present times, induced me to
extend my researches to the later, historical periods as well;
especially, to study that most interesting period—the free medieval
city republics, of which the universality and influence upon our
modern civilization have not yet been duly appreciated. And
finally, I have tried to indicate in brief the immense importance
which the mutual-support instincts, inherited by mankind from its
extremely long evolution, play even now in our modern society,
which is supposed to rest upon the principle: "every one for
himself, and the State for all," but which it never has succeeded,
nor will succeed in realizing.It may be objected to this book that both animals and men are
represented in it under too favourable an aspect; that their
sociable qualities are insisted upon, while their anti-social and
self-asserting instincts are hardly touched upon. This was,
however, unavoidable. We have heard so much lately of the "harsh,
pitiless struggle for life," which was said to be carried on by
every animal against all other animals, every "savage" against all
other "savages," and every civilized man against all his
co-citizens—and these assertions have so much become an article of
faith—that it was necessary, first of all, to oppose to them a wide
series of facts showing animal and human life under a quite
different aspect. It was necessary to indicate the overwhelming
importance which sociable habits play in Nature and in the
progressive evolution of both the animal species and human beings:
to prove that they secure to animals a better protection from their
enemies, very often facilities for getting food and (winter
provisions, migrations, etc.), longevity, therefore a greater
facility for the development of intellectual faculties; and that
they have given to men, in addition to the same advantages, the
possibility of working out those institutions which have enabled
mankind to survive in its hard struggle against Nature, and to
progress, notwithstanding all the vicissitudes of its history. It
is a book on the law of Mutual Aid, viewed at as one of the chief
factors of evolution—not on all factors of evolution and their
respective values; and this first book had to be written, before
the latter could become possible.I should certainly be the last to underrate the part which
the self-assertion of the individual has played in the evolution of
mankind. However, this subject requires, I believe, a much deeper
treatment than the one it has hitherto received. In the history of
mankind, individual self-assertion has often been, and continually
is, something quite different from, and far larger and deeper than,
the petty, unintelligent narrow-mindedness, which, with a large
class of writers, goes for "individualism" and "self-assertion."
Nor have history-making individuals been limited to those whom
historians have represented as heroes. My intention, consequently,
is, if circumstances permit it, to discuss separately the part
taken by the self-assertion of the individual in the progressive
evolution of mankind. I can only make in this place the following
general remark:—When the Mutual Aid institutions—the tribe, the
village community, the guilds, the medieval city—began, in the
course of history, to lose their primitive character, to be invaded
by parasitic growths, and thus to become hindrances to progress,
the revolt of individuals against these institutions took always
two different aspects. Part of those who rose up strove to purify
the old institutions, or to work out a higher form of commonwealth,
based upon the same Mutual Aid principles; they tried, for
instance, to introduce the principle of "compensation," instead of
the lex talionis, and later on, the pardon of offences, or a still
higher ideal of equality before the human conscience, in lieu of
"compensation," according to class-value. But at the very same
time, another portion of the same individual rebels endeavoured to
break down the protective institutions of mutual support, with no
other intention but to increase their own wealth and their own
powers. In this three-cornered contest, between the two classes of
revolted individuals and the supporters of what existed, lies the
real tragedy of history. But to delineate that contest, and
honestly to study the part played in the evolution of mankind by
each one of these three forces, would require at least as many
years as it took me to write this book.Of works dealing with nearly the same subject, which have
been published since the publication of my articles on Mutual Aid
among Animals, I must mention The Lowell Lectures on the Ascent of
Man, by Henry Drummond (London, 1894), and The Origin and Growth of
the Moral Instinct, by A. Sutherland (London, 1898). Both are
constructed chiefly on the lines taken in Buchner's Love, and in
the second work the parental and familial feeling as the sole
influence at work in the development of the moral feelings has been
dealt with at some length. A third work dealing with man and
written on similar lines is The Principles of Sociology, by Prof.
F.A. Giddings, the first edition of which was published in 1896 at
New York and London, and the leading ideas of which were sketched
by the author in a pamphlet in 1894. I must leave, however, to
literary critics the task of discussing the points of contact,
resemblance, or divergence between these works and
mine.The different chapters of this book were published first in
the Nineteenth Century ("Mutual Aid among Animals," in September
and November 1890; "Mutual Aid among Savages," in April 1891;
"Mutual Aid among the Barbarians," in January 1892; "Mutual Aid in
the Medieval City," in August and September 1894; and "Mutual Aid
amongst Modern Men," in January and June 1896). In bringing them
out in a book form my first intention was to embody in an Appendix
the mass of materials, as well as the discussion of several
secondary points, which had to be omitted in the review articles.
It appeared, however, that the Appendix would double the size of
the book, and I was compelled to abandon, or, at least, to postpone
its publication. The present Appendix includes the discussion of
only a few points which have been the matter of scientific
controversy during the last few years; and into the text I have
introduced only such matter as could be introduced without altering
the structure of the work.I am glad of this opportunity for expressing to the editor of
the Nineteenth Century, Mr. James Knowles, my very best thanks,
both for the kind hospitality which he offered to these papers in
his review, as soon as he knew their general idea, and the
permission he kindly gave me to reprint them.
CHAPTER I
MUTUAL AID AMONG ANIMALSStruggle for existence. Mutual Aid a law of Nature and chief
factor of progressive evolution. Invertebrates. Ants and Bees.
Birds, hunting and fishing associations. Sociability. Mutual
protection among small birds. Cranes, parrots.The conception of struggle for existence as a factor of
evolution, introduced into science by Darwin and Wallace, has
permitted us to embrace an immensely wide range of phenomena in one
single generalization, which soon became the very basis of our
philosophical, biological, and sociological speculations. An
immense variety of facts:—adaptations of function and structure of
organic beings to their surroundings; physiological and anatomical
evolution; intellectual progress, and moral development itself,
which we formerly used to explain by so many different causes, were
embodied by Darwin in one general conception. We understood them as
continued endeavours—as a struggle against adverse
circumstances—for such a development of individuals, races, species
and societies, as would result in the greatest possible fulness,
variety, and intensity of life. It may be that at the outset Darwin
himself was not fully aware of the generality of the factor which
he first invoked for explaining one series only of facts relative
to the accumulation of individual variations in incipient species.
But he foresaw that the term which he was introducing into science
would lose its philosophical and its only true meaning if it were
to be used in its narrow sense only—that of a struggle between
separate individuals for the sheer means of existence. And at the
very beginning of his memorable work he insisted upon the term
being taken in its "large and metaphorical sense including
dependence of one being on another, and including (which is more
important) not only the life of the individual, but success in
leaving progeny."(1)While he himself was chiefly using the term in its narrow
sense for his own special purpose, he warned his followers against
committing the error (which he seems once to have committed
himself) of overrating its narrow meaning. In The Descent of Man he
gave some powerful pages to illustrate its proper, wide sense. He
pointed out how, in numberless animal societies, the struggle
between separate individuals for the means of existence disappears,
how struggle is replaced by co-operation, and how that substitution
results in the development of intellectual and moral faculties
which secure to the species the best conditions for survival. He
intimated that in such cases the fittest are not the physically
strongest, nor the cunningest, but those who learn to combine so as
mutually to support each other, strong and weak alike, for the
welfare of the community. "Those communities," he wrote, "which
included the greatest number of the most sympathetic members would
flourish best, and rear the greatest number of offspring" (2nd
edit., p. 163). The term, which originated from the narrow
Malthusian conception of competition between each and all, thus
lost its narrowness in the mind of one who knew
Nature.Unhappily, these remarks, which might have become the basis
of most fruitful researches, were overshadowed by the masses of
facts gathered for the purpose of illustrating the consequences of
a real competition for life. Besides, Darwin never attempted to
submit to a closer investigation the relative importance of the two
aspects under which the struggle for existence appears in the
animal world, and he never wrote the work he proposed to write upon
the natural checks to over-multiplication, although that work would
have been the crucial test for appreciating the real purport of
individual struggle. Nay, on the very pages just mentioned, amidst
data disproving the narrow Malthusian conception of struggle, the
old Malthusian leaven reappeared—namely, in Darwin's remarks as to
the alleged inconveniences of maintaining the "weak in mind and
body" in our civilized societies (ch. v). As if thousands of
weak-bodied and infirm poets, scientists, inventors, and reformers,
together with other thousands of so-called "fools" and "weak-minded
enthusiasts," were not the most precious weapons used by humanity
in its struggle for existence by intellectual and moral arms, which
Darwin himself emphasized in those same chapters of Descent of
Man.It happened with Darwin's theory as it always happens with
theories having any bearing upon human relations. Instead of
widening it according to his own hints, his followers narrowed it
still more. And while Herbert Spencer, starting on independent but
closely allied lines, attempted to widen the inquiry into that
great question, "Who are the fittest?" especially in the appendix
to the third edition of the Data of Ethics, the numberless
followers of Darwin reduced the notion of struggle for existence to
its narrowest limits. They came to conceive the animal world as a
world of perpetual struggle among half-starved individuals,
thirsting for one another's blood. They made modern literature
resound with the war-cry of woe to the vanquished, as if it were
the last word of modern biology. They raised the "pitiless"
struggle for personal advantages to the height of a biological
principle which man must submit to as well, under the menace of
otherwise succumbing in a world based upon mutual extermination.
Leaving aside the economists who know of natural science but a few
words borrowed from second-hand vulgarizers, we must recognize that
even the most authorized exponents of Darwin's views did their best
to maintain those false ideas. In fact, if we take Huxley, who
certainly is considered as one of the ablest exponents of the
theory of evolution, were we not taught by him, in a paper on the
'Struggle for Existence and its Bearing upon Man,'
that,"from the point of view of the moralist, the animal world is
on about the same level as a gladiators' show. The creatures are
fairly well treated, and set to, fight hereby the strongest, the
swiftest, and the cunningest live to fight another day. The
spectator has no need to turn his thumb down, as no quarter is
given."Or, further down in the same article, did he not tell us
that, as among animals, so among primitive men,"the weakest and stupidest went to the wall, while the
toughest and shrewdest, those who were best fitted to cope with
their circumstances, but not the best in another way, survived.
Life was a continuous free fight, and beyond the limited and
temporary relations of the family, the Hobbesian war of each
against all was the normal state of existence."(2)In how far this view of nature is supported by fact, will be
seen from the evidence which will be here submitted to the reader
as regards the animal world, and as regards primitive man. But it
may be remarked at once that Huxley's view of nature had as little
claim to be taken as a scientific deduction as the opposite view of
Rousseau, who saw in nature but love, peace, and harmony destroyed
by the accession of man. In fact, the first walk in the forest, the
first observation upon any animal society, or even the perusal of
any serious work dealing with animal life (D'Orbigny's, Audubon's,
Le Vaillant's, no matter which), cannot but set the naturalist
thinking about the part taken by social life in the life of
animals, and prevent him from seeing in Nature nothing but a field
of slaughter, just as this would prevent him from seeing in Nature
nothing but harmony and peace. Rousseau had committed the error of
excluding the beak-and-claw fight from his thoughts; and Huxley
committed the opposite error; but neither Rousseau's optimism nor
Huxley's pessimism can be accepted as an impartial interpretation
of nature.As soon as we study animals—not in laboratories and museums
only, but in the forest and the prairie, in the steppe and the
mountains—we at once perceive that though there is an immense
amount of warfare and extermination going on amidst various
species, and especially amidst various classes of animals, there
is, at the same time, as much, or perhaps even more, of mutual
support, mutual aid, and mutual defence amidst animals belonging to
the same species or, at least, to the same society. Sociability is
as much a law of nature as mutual struggle. Of course it would be
extremely difficult to estimate, however roughly, the relative
numerical importance of both these series of facts. But if we
resort to an indirect test, and ask Nature: "Who are the fittest:
those who are continually at war with each other, or those who
support one another?" we at once see that those animals which
acquire habits of mutual aid are undoubtedly the fittest. They have
more chances to survive, and they attain, in their respective
classes, the highest development of intelligence and bodily
organization. If the numberless facts which can be brought forward
to support this view are taken into account, we may safely say that
mutual aid is as much a law of animal life as mutual struggle, but
that, as a factor of evolution, it most probably has a far greater
importance, inasmuch as it favours the development of such habits
and characters as insure the maintenance and further development of
the species, together with the greatest amount of welfare and
enjoyment of life for the individual, with the least waste of
energy.Of the scientific followers of Darwin, the first, as far as I
know, who understood the full purport of Mutual Aid as a law of
Nature and the chief factor of evolution, was a well-known Russian
zoologist, the late Dean of the St. Petersburg University,
Professor Kessler. He developed his ideas in an address which he
delivered in January 1880, a few months before his death, at a
Congress of Russian naturalists; but, like so many good things
published in the Russian tongue only, that remarkable address
remains almost entirely unknown.(3)"As a zoologist of old standing," he felt bound to protest
against the abuse of a term—the struggle for existence—borrowed
from zoology, or, at least, against overrating its importance.
Zoology, he said, and those sciences which deal with man,
continually insist upon what they call the pitiless law of struggle
for existence. But they forget the existence of another law which
may be described as the law of mutual aid, which law, at least for
the animals, is far more essential than the former. He pointed out
how the need of leaving progeny necessarily brings animals
together, and, "the more the individuals keep together, the more
they mutually support each other, and the more are the chances of
the species for surviving, as well as for making further progress
in its intellectual development." "All classes of animals," he
continued, "and especially the higher ones, practise mutual aid,"
and he illustrated his idea by examples borrowed from the life of
the burying beetles and the social life of birds and some mammalia.
The examples were few, as might have been expected in a short
opening address, but the chief points were clearly stated; and,
after mentioning that in the evolution of mankind mutual aid played
a still more prominent part, Professor Kessler concluded as
follows:—"I obviously do not deny the struggle for existence, but I
maintain that the progressive development of the animal kingdom,
and especially of mankind, is favoured much more by mutual support
than by mutual struggle…. All organic beings have two essential
needs: that of nutrition, and that of propagating the species. The
former brings them to a struggle and to mutual extermination, while
the needs of maintaining the species bring them to approach one
another and to support one another. But I am inclined to think that
in the evolution of the organic world—in the progressive
modification of organic beings—mutual support among individuals
plays a much more important part than their mutual
struggle."(4)The correctness of the above views struck most of the Russian
zoologists present, and Syevertsoff, whose work is well known to
ornithologists and geographers, supported them and illustrated them
by a few more examples. He mentioned sone of the species of falcons
which have "an almost ideal organization for robbery," and
nevertheless are in decay, while other species of falcons, which
practise mutual help, do thrive. "Take, on the other side, a
sociable bird, the duck," he said; "it is poorly organized on the
whole, but it practises mutual support, and it almost invades the
earth, as may be judged from its numberless varieties and
species."The readiness of the Russian zoologists to accept Kessler's
views seems quite natural, because nearly all of them have had
opportunities of studying the animal world in the wide uninhabited
regions of Northern Asia and East Russia; and it is impossible to
study like regions without being brought to the same ideas. I
recollect myself the impression produced upon me by the animal
world of Siberia when I explored the Vitim regions in the company
of so accomplished a zoologist as my friend Polyakoff was. We both
were under the fresh impression of the Origin of Species, but we
vainly looked for the keen competition between animals of the same
species which the reading of Darwin's work had prepared us to
expect, even after taking into account the remarks of the third
chapter (p. 54). We saw plenty of adaptations for struggling, very
often in common, against the adverse circumstances of climate, or
against various enemies, and Polyakoff wrote many a good page upon
the mutual dependency of carnivores, ruminants, and rodents in
their geographical distribution; we witnessed numbers of facts of
mutual support, especially during the migrations of birds and
ruminants; but even in the Amur and Usuri regions, where animal
life swarms in abundance, facts of real competition and struggle
between higher animals of the same species came very seldom under
my notice, though I eagerly searched for them. The same impression
appears in the works of most Russian zoologists, and it probably
explains why Kessler's ideas were so welcomed by the Russian
Darwinists, whilst like ideas are not in vogue amidst the followers
of Darwin in Western Europe.The first thing which strikes us as soon as we begin studying
the struggle for existence under both its aspects—direct and
metaphorical—is the abundance of facts of mutual aid, not only for
rearing progeny, as recognized by most evolutionists, but also for
the safety of the individual, and for providing it with the
necessary food. With many large divisions of the animal kingdom
mutual aid is the rule. Mutual aid is met with even amidst the
lowest animals, and we must be prepared to learn some day, from the
students of microscopical pond-life, facts of unconscious mutual
support, even from the life of micro-organisms. Of course, our
knowledge of the life of the invertebrates, save the termites, the
ants, and the bees, is extremely limited; and yet, even as regards
the lower animals, we may glean a few facts of well-ascertained
cooperation. The numberless associations of locusts, vanessae,
cicindelae, cicadae, and so on, are practically quite unexplored;
but the very fact of their existence indicates that they must be
composed on about the same principles as the temporary associations
of ants or bees for purposes of migration. As to the beetles, we
have quite well-observed facts of mutual help amidst the burying
beetles (Necrophorus). They must have some decaying organic matter
to lay their eggs in, and thus to provide their larvae with food;
but that matter must not decay very rapidly. So they are wont to
bury in the ground the corpses of all kinds of small animals which
they occasionally find in their rambles. As a rule, they live an
isolated life, but when one of them has discovered the corpse of a
mouse or of a bird, which it hardly could manage to bury itself, it
calls four, six, or ten other beetles to perform the operation with
united efforts; if necessary, they transport the corpse to a
suitable soft ground; and they bury it in a very considerate way,
without quarrelling as to which of them will enjoy the privilege of
laying its eggs in the buried corpse. And when Gleditsch attached a
dead bird to a cross made out of two sticks, or suspended a toad to
a stick planted in the soil, the little beetles would in the same
friendly way combine their intelligences to overcome the artifice
of Man. The same combination of efforts has been noticed among the
dung-beetles.Even among animals standing at a somewhat lower stage of
organization we may find like examples. Some land-crabs of the West
Indies and North America combine in large swarms in order to travel
to the sea and to deposit therein their spawn; and each such
migration implies concert, co-operation, and mutual support. As to
the big Molucca crab (Limulus), I was struck (in 1882, at the
Brighton Aquarium) with the extent of mutual assistance which these
clumsy animals are capable of bestowing upon a comrade in case of
need. One of them had fallen upon its back in a corner of the tank,
and its heavy saucepan-like carapace prevented it from returning to
its natural position, the more so as there was in the corner an
iron bar which rendered the task still more difficult. Its comrades
came to the rescue, and for one hour's time I watched how they
endeavoured to help their fellow-prisoner. They came two at once,
pushed their friend from beneath, and after strenuous efforts
succeeded in lifting it upright; but then the iron bar would
prevent them from achieving the work of rescue, and the crab would
again heavily fall upon its back. After many attempts, one of the
helpers would go in the depth of the tank and bring two other
crabs, which would begin with fresh forces the same pushing and
lifting of their helpless comrade. We stayed in the Aquarium for
more than two hours, and, when leaving, we again came to cast a
glance upon the tank: the work of rescue still continued! Since I
saw that, I cannot refuse credit to the observation quoted by Dr.
Erasmus Darwin—namely, that "the common crab during the moulting
season stations as sentinel an unmoulted or hard-shelled individual
to prevent marine enemies from injuring moulted individuals in
their unprotected state."(5)Facts illustrating mutual aid amidst the termites, the ants,
and the bees are so well known to the general reader, especially
through the works of Romanes, L. Buchner, and Sir John Lubbock,
that I may limit my remarks to a very few hints.(6) If we take an
ants' nest, we not only see that every description of work-rearing
of progeny, foraging, building, rearing of aphides, and so on—is
performed according to the principles of voluntary mutual aid; we
must also recognize, with Forel, that the chief, the fundamental
feature of the life of many species of ants is the fact and the
obligation for every ant of sharing its food, already swallowed and
partly digested, with every member of the community which may apply
for it. Two ants belonging to two different species or to two
hostile nests, when they occasionally meet together, will avoid
each other. But two ants belonging to the same nest or to the same
colony of nests will approach each other, exchange a few movements
with the antennae, and "if one of them is hungry or thirsty, and
especially if the other has its crop full … it immediately asks for
food." The individual thus requested never refuses; it sets apart
its mandibles, takes a proper position, and regurgitates a drop of
transparent fluid which is licked up by the hungry ant.
Regurgitating food for other ants is so prominent a feature in the
life of ants (at liberty), and it so constantly recurs both for
feeding hungry comrades and for feeding larvae, that Forel
considers the digestive tube of the ants as consisting of two
different parts, one of which, the posterior, is for the special
use of the individual, and the other, the anterior part, is chiefly
for the use of the community. If an ant which has its crop full has
been selfish enough to refuse feeding a comrade, it will be treated
as an enemy, or even worse. If the refusal has been made while its
kinsfolk were fighting with some other species, they will fall back
upon the greedy individual with greater vehemence than even upon
the enemies themselves. And if an ant has not refused to feed
another ant belonging to an enemy species, it will be treated by
the kinsfolk of the latter as a friend. All this is confirmed by
most accurate observation and decisive experiments.(7)In that immense division of the animal kingdom which embodies
more than one thousand species, and is so numerous that the
Brazilians pretend that Brazil belongs to the ants, not to men,
competition amidst the members of the same nest, or the colony of
nests, does not exist. However terrible the wars between different
species, and whatever the atrocities committed at war-time, mutual
aid within the community, self-devotion grown into a habit, and
very often self-sacrifice for the common welfare, are the rule. The
ants and termites have renounced the "Hobbesian war," and they are
the better for it. Their wonderful nests, their buildings, superior
in relative size to those of man; their paved roads and overground
vaulted galleries; their spacious halls and granaries; their
corn-fields, harvesting and "malting" of grain;(8) their, rational
methods of nursing their eggs and larvae, and of building special
nests for rearing the aphides whom Linnaeus so picturesquely
described as "the cows of the ants"; and, finally, their courage,
pluck, and, superior intelligence—all these are the natural outcome
of the mutual aid which they practise at every stage of their busy
and laborious lives. That mode of life also necessarily resulted in
the development of another essential feature of the life of ants:
the immense development of individual initiative which, in its
turn, evidently led to the development of that high and varied
intelligence which cannot but strike the human
observer.(9)If we knew no other facts from animal life than what we know
about the ants and the termites, we already might safely conclude
that mutual aid (which leads to mutual confidence, the first
condition for courage) and individual initiative (the first
condition for intellectual progress) are two factors infinitely
more important than mutual struggle in the evolution of the animal
kingdom. In fact, the ant thrives without having any of the
"protective" features which cannot be dispensed with by animals
living an isolated life. Its colour renders it conspicuous to its
enemies, and the lofty nests of many species are conspicuous in the
meadows and forests. It is not protected by a hard carapace, and
its stinging apparatus, however dangerous when hundreds of stings
are plunged into the flesh of an animal, is not of a great value
for individual defence; while the eggs and larvae of the ants are a
dainty for a great number of the inhabitants of the forests. And
yet the ants, in their thousands, are not much destroyed by the
birds, not even by the ant-eaters, and they are dreaded by most
stronger insects. When Forel emptied a bagful of ants in a meadow,
he saw that "the crickets ran away, abandoning their holes to be
sacked by the ants; the grasshoppers and the crickets fled in all
directions; the spiders and the beetles abandoned their prey in
order not to become prey themselves;" even the nests of the wasps
were taken by the ants, after a battle during which many ants
perished for the safety of the commonwealth. Even the swiftest
insects cannot escape, and Forel often saw butterflies, gnats,
flies, and so on, surprised and killed by the ants. Their force is
in mutual support and mutual confidence. And if the ant—apart from
the still higher developed termites—stands at the very top of the
whole class of insects for its intellectual capacities; if its
courage is only equalled by the most courageous vertebrates; and if
its brain—to use Darwin's words—"is one of the most marvellous
atoms of matter in the world, perhaps more so than the brain of
man," is it not due to the fact that mutual aid has entirely taken
the place of mutual struggle in the communities of
ants?The same is true as regards the bees. These small insects,
which so easily might become the prey of so many birds, and whose
honey has so many admirers in all classes of animals from the
beetle to the bear, also have none of the protective features
derived from mimicry or otherwise, without which an isolatedly
living insect hardly could escape wholesale destruction; and yet,
owing to the mutual aid they practise, they obtain the wide
extension which we know and the intelligence we admire, By working
in common they multiply their individual forces; by resorting to a
temporary division of labour combined with the capacity of each bee
to perform every kind of work when required, they attain such a
degree of well-being and safety as no isolated animal can ever
expect to achieve however strong or well armed it may be. In their
combinations they are often more successful than man, when he
neglects to take advantage of a well-planned mutual assistance.
Thus, when a new swarm of bees is going to leave the hive in search
of a new abode, a number of bees will make a preliminary
exploration of the neighbourhood, and if they discover a convenient
dwelling-place—say, an old basket, or anything of the kind—they
will take possession of it, clean it, and guard it, sometimes for a
whole week, till the swarm comes to settle therein. But how many
human settlers will perish in new countries simply for not having
understood the necessity of combining their efforts! By combining
their individual intelligences they succeed in coping with adverse
circumstances, even quite unforeseen and unusual, like those bees
of the Paris Exhibition which fastened with their resinous propolis
the shutter to a glass-plate fitted in the wall of their hive.
Besides, they display none of the sanguinary proclivities and love
of useless fighting with which many writers so readily endow
animals. The sentries which guard the entrance to the hive
pitilessly put to death the robbing bees which attempt entering the
hive; but those stranger bees which come to the hive by mistake are
left unmolested, especially if they come laden with pollen, or are
young individuals which can easily go astray. There is no more
warfare than is strictly required.The sociability of the bees is the more instructive as
predatory instincts and laziness continue to exist among the bees
as well, and reappear each time that their growth is favoured by
some circumstances. It is well known that there always are a number
of bees which prefer a life of robbery to the laborious life of a
worker; and that both periods of scarcity and periods of an
unusually rich supply of food lead to an increase of the robbing
class. When our crops are in and there remains but little to gather
in our meadows and fields, robbing bees become of more frequent
occurrence; while, on the other side, about the sugar plantations
of the West Indies and the sugar refineries of Europe, robbery,
laziness, and very often drunkenness become quite usual with the
bees. We thus see that anti-social instincts continue to exist
amidst the bees as well; but natural selection continually must
eliminate them, because in the long run the practice of solidarity
proves much more advantageous to the species than the development
of individuals endowed with predatory inclinations. The cunningest
and the shrewdest are eliminated in favour of those who understand
the advantages of sociable life and mutual support.Certainly, neither the ants, nor the bees, nor even the
termites, have risen to the conception of a higher solidarity
embodying the whole of the species. In that respect they evidently
have not attained a degree of development which we do not find even
among our political, scientific, and religious leaders. Their
social instincts hardly extend beyond the limits of the hive or the
nest. However, colonies of no less than two hundred nests,
belonging to two different species (Formica exsecta and F.
pressilabris) have been described by Forel on Mount Tendre and
Mount Saleve; and Forel maintains that each member of these
colonies recognizes every other member of the colony, and that they
all take part in common defence; while in Pennsylvania Mr. MacCook
saw a whole nation of from 1,600 to 1,700 nests of the mound-making
ant, all living in perfect intelligence; and Mr. Bates has
described the hillocks of the termites covering large surfaces in
the "campos"—some of the nests being the refuge of two or three
different species, and most of them being connected by vaulted
galleries or arcades.(10) Some steps towards the amalgamation of
larger divisions of the species for purposes of mutual protection
are thus met with even among the invertebrate animals.Going now over to higher animals, we find far more instances
of undoubtedly conscious mutual help for all possible purposes,
though we must recognize at once that our knowledge even of the
life of higher animals still remains very imperfect. A large number
of facts have been accumulated by first-rate observers, but there
are whole divisions of the animal kingdom of which we know almost
nothing. Trustworthy information as regards fishes is extremely
scarce, partly owing to the difficulties of observation, and partly
because no proper attention has yet been paid to the subject. As to
the mammalia, Kessler already remarked how little we know about
their manners of life. Many of them are nocturnal in their habits;
others conceal themselves underground; and those ruminants whose
social life and migrations offer the greatest interest do not let
man approach their herds. It is chiefly upon birds that we have the
widest range of information, and yet the social life of very many
species remains but imperfectly known. Still, we need not complain
about the lack of well-ascertained facts, as will be seen from the
following.I need not dwell upon the associations of male and female for
rearing their offspring, for providing it with food during their
first steps in life, or for hunting in common; though it may be
mentioned by the way that such associations are the rule even with
the least sociable carnivores and rapacious birds; and that they
derive a special interest from being the field upon which tenderer
feelings develop even amidst otherwise most cruel animals. It may
also be added that the rarity of associations larger than that of
the family among the carnivores and the birds of prey, though
mostly being the result of their very modes of feeding, can also be
explained to some extent as a consequence of the change produced in
the animal world by the rapid increase of mankind. At any rate it
is worthy of note that there are species living a quite isolated
life in densely-inhabited regions, while the same species, or their
nearest congeners, are gregarious in uninhabited countries. Wolves,
foxes, and several birds of prey may be quoted as instances in
point.However, associations which do not extend beyond the family
bonds are of relatively small importance in our case, the more so
as we know numbers of associations for more general purposes, such
as hunting, mutual protection, and even simple enjoyment of life.
Audubon already mentioned that eagles occasionally associate for
hunting, and his description of the two bald eagles, male and
female, hunting on the Mississippi, is well known for its graphic
powers. But one of the most conclusive observations of the kind
belongs to Syevertsoff. Whilst studying the fauna of the Russian
Steppes, he once saw an eagle belonging to an altogether gregarious
species (the white-tailed eagle, Haliactos albicilla) rising high
in the air for half an hour it was describing its wide circles in
silence when at once its piercing voice was heard. Its cry was soon
answered by another eagle which approached it, and was followed by
a third, a fourth, and so on, till nine or ten eagles came together
and soon disappeared. In the afternoon, Syevertsoff went to the
place whereto he saw the eagles flying; concealed by one of the
undulations of the Steppe, he approached them, and discovered that
they had gathered around the corpse of a horse. The old ones,
which, as a rule, begin the meal first—such are their rules of
propriety-already were sitting upon the haystacks of the
neighbourhood and kept watch, while the younger ones were
continuing the meal, surrounded by bands of crows. From this and
like observations, Syevertsoff concluded that the white-tailed
eagles combine for hunting; when they all have risen to a great
height they are enabled, if they are ten, to survey an area of at
least twenty-five miles square; and as soon as any one has
discovered something, he warns the others.(11) Of course, it might
be argued that a simple instinctive cry of the first eagle, or even
its movements, would have had the same effect of bringing several
eagles to the prey. But in this case there is strong evidence in
favour of mutual warning, because the ten eagles came together
before descending towards the prey, and Syevertsoff had later on
several opportunities of ascertaining that the whitetailed eagles
always assemble for devouring a corpse, and that some of them (the
younger ones first) always keep watch while the others are eating.
In fact, the white-tailed eagle—one of the bravest and best
hunters—is a gregarious bird altogether, and Brehm says that when
kept in captivity it very soon contracts an attachment to its
keepers.
