All of these are forms of control in which compet.i.tion is limited by status.

Conflict is then to be identified with the political order and with conscious control. Accommodation, on the other hand, is a.s.sociated with the social order that is fixed and established in custom and the mores.

a.s.similation, as distinguished from accommodation, implies a more thoroughgoing transformation of the personality--a transformation which takes place gradually under the influence of social contacts of the most concrete and intimate sort.

Accommodation may be regarded, like religious conversion, as a kind of mutation. The wishes are the same but their organization is different.

a.s.similation takes place not so much as a result of changes in the organization as in the content, i.e., the memories, of the personality.

The individual units, as a result of intimate a.s.sociation, interpenetrate, so to speak, and come in this way into possession of a common experience and a common tradition. The permanence and solidarity of the group rest finally upon this body of common experience and tradition. It is the role of history to preserve this body of common experience and tradition, to criticise and reinterpret it in the light of new experience and changing conditions, and in this way to preserve the continuity of the social and political life.

The relation of social structures to the processes of compet.i.tion, conflict, accommodation, and a.s.similation may be represented schematically as follows:

3. Cla.s.sification of the Materials

The materials in this chapter have been selected to exhibit (1) the role which compet.i.tion plays in social life and all life, and (2) the types of organization that compet.i.tion has everywhere created as a result of the division of labor it has everywhere enforced. These materials fall naturally under the following heads: (a) the struggle for existence; (b) compet.i.tion and segregation; and (c) economic compet.i.tion.

This order of the materials serves the purpose of indicating the stages in the growth and extension of man's control over nature and over man himself. The evolution of society has been the progressive extension of control over nature and the subst.i.tution of a moral for the natural order.

Compet.i.tion has its setting in the struggle for existence. This struggle is ordinarily represented as a chaos of contending individuals in which the unfit perish in order that the fit may survive. This conception of the natural order as one of anarchy, "the war of each against all,"

familiar since Hobbes to the students of society, is recent in biology.

Before Darwin, students of plant and animal life saw in nature, not disorder, but order; not selection, but design. The difference between the older and the newer interpretation is not so much a difference of fact as of point of view. Looking at the plant and animal species with reference to their cla.s.sification they present a series of relatively fixed and stable types. The same thing may be said of the plant and animal communities. Under ordinary circ.u.mstances the adjustment between the members of the plant and animal communities and the environment is so complete that the observer interprets it as an order of co-operation rather than a condition of compet.i.tive anarchy.

Upon investigation it turns out, however, that the plant and animal communities are in a state of unstable equilibrium, such that any change in the environment may destroy them. Communities of this type are not organized to resist or adapt themselves as communities to changes in the environment. The plant community, for example, is a mere product of segregation, an aggregate without nerves or means of communication that would permit the individuals to be controlled in the interest of the community as a whole.[183]

The situation is different in the so-called animal societies. Animals are adapted in part to the situation of compet.i.tion, but in part also to the situation of co-operation. With the animal, maternal instinct, gregariousness, s.e.x attraction restrict compet.i.tion to a greater or less extent among individuals of the same family, herd, or species. In the case of the ant community compet.i.tion is at a minimum and co-operation at a maximum.

With man the free play of compet.i.tion is restrained by sentiment, custom, and moral standards, not to speak of the more conscious control through law.

It is a characteristic of compet.i.tion, when unrestricted, that it is invariably more severe among organisms of the same than of different species. Man's greatest compet.i.tor is man. On the other hand, man's control over the plant and animal world is now well-nigh complete, so that, generally speaking, only such plants and animals are permitted to exist as serve man's purpose.

Compet.i.tion among men, on the other hand, has been very largely converted into rivalry and conflict. The effect of conflict has been to extend progressively the area of control and to modify and limit the struggle for existence within these areas. The effect of war has been, on the whole, to extend the area over which there is peace. Compet.i.tion has been restricted by custom, tradition, and law, and the struggle for existence has a.s.sumed the form of struggle for a livelihood and for status.

Absolute free play of compet.i.tion is neither desirable nor even possible. On the other hand, from the standpoint of the individual, compet.i.tion means mobility, freedom, and, from the point of view of society, pragmatic or experimental change. Restriction of compet.i.tion is synonymous with limitation of movement, acquiescence in control, and telesis, Ward's term for changes ordained by society in distinction from the natural process of change.

The political problem of every society is the practical one: how to secure the maximum values of compet.i.tion, that is, personal freedom, initiative, and originality, and at the same time to control the energies which compet.i.tion has released in the interest of the community.

II. MATERIALS

A. THE STRUGGLE FOR EXISTENCE

1. Different Forms of the Struggle for Existence[184]

The formula "struggle for existence," familiar in human affairs, was used by Darwin in his interpretation of organic life, and he showed that we gain clearness in our outlook on animate nature if we recognize there, in continual process, a struggle for existence not merely a.n.a.logous to, but fundamentally the same as, that which goes on in human life. He projected on organic life a sociological idea, and showed that it fitted. But while he thus vindicated the relevancy and utility of the sociological idea within the biological realm, he declared explicitly that the phrase "struggle for existence" was meant to be a shorthand formula, summing up a vast variety of strife and endeavor, of thrust and parry, of action and reaction.

Some of Darwin's successors have taken pains to distinguish a great many different forms of the struggle for existence, and this kind of a.n.a.lysis is useful in keeping us aware of the complexities of the process. Darwin himself does not seem to have cared much for this logical mapping out and defining; it was enough for him to insist that the phrase was used "in a large and metaphorical sense," and to give full ill.u.s.trations of its various modes. For our present purpose it is enough for us to follow his example.

a) _Struggle between fellows._--When the locusts of a huge swarm have eaten up every green thing, they sometimes turn on one another. This cannibalism among fellows of the same species--ill.u.s.trated, for instance, among many fishes--is the most intense form of the struggle for existence. The struggle does not need to be direct to be real; the essential point is that the compet.i.tors seek after the same desiderata, of which there is a limited supply.

As an instance of keen struggle between nearly related species, Darwin referred to the combats of rats. The black rat was in possession of many European towns before the brown rat crossed the Volga in 1727; whenever the brown rat arrived, the black rat had to go to the wall. Thus at the present day there are practically no black rats in Great Britain. Here the struggle for existence is again directly compet.i.tive. It is difficult to separate the struggle for food and foothold from the struggle for mates, and it seems clearest to include here the battles of the stags and the capercailzies, or the extraordinary lek of the blackc.o.c.k, showing off their beauty at sunrise on the hills.

b) _Struggle between foes._--In the locust swarm and in the rats'

combats there is compet.i.tion between fellows of the same or nearly related species, but the struggle for existence includes much wider antipathies. We see it between foes of entirely different nature, between carnivores and herbivores, between birds of prey and small mammals. In both these cases there may be a stand-up fight, for instance between wolf and stag, or between hawk and ermine; but neither the logic nor the biology of the process is different when all the fight is on one side. As the lemmings, which have overpopulated the Scandinavian valleys, go on the march they are followed by birds and beasts of prey, which thin their ranks. Moreover, the compet.i.tion between species need not be direct; it will come to the same result if both types seek after the same things. The victory will be with the more effective and the more prolific.

c) _Struggle with fate._--Our sweep widens still further, and we pa.s.s beyond the idea of compet.i.tion altogether to cases where the struggle for existence is between the living organism and the inanimate conditions of its life--for instance, between birds and the winter's cold, between aquatic animals and changes in the water, between plants and drought, between plants and frost--in a wide sense, between Life and Fate.

We cannot here pursue the suggestive idea that, besides struggle between individuals, there is struggle between groups of individuals--the latter most noticeably developed in mankind. Similarly, working in the other direction, there is struggle between parts or tissues in the body, between cells in the body, between equivalent germ-cells, and, perhaps, as Weismann pictures, between the various multiplicate items that make up our inheritance.

2. Compet.i.tion and Natural Selection[185]

The term "struggle for existence" is used in a 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. Two canine animals in a time of dearth may be truly said to struggle with each other which shall get food and live.

But a plant on the edge of a desert is said to struggle for life against the drought, though more properly it should be said to be dependent on the moisture. A plant which annually produces a thousand seeds, of which only one of an average comes to maturity, may be more truly said to struggle with the plants of the same and other kinds which already clothe the ground. The mistletoe is dependent on the apple and a few other trees, but can only in a far-fetched sense be said to struggle with these trees, for, if too many of these parasites grow on the same tree, it languishes and dies. But several seedling mistletoes growing close together on the same branch may more truly be said to struggle with each other. As the mistletoe is disseminated by birds, its existence depends on them; and it may metaphorically be said to struggle with other fruit-bearing plants in tempting the birds to devour and thus disseminate its seeds. In these several senses which pa.s.s into each other, I use for convenience' sake the general term of "struggle for existence."

A struggle for existence inevitably follows from the high rate at which all organic beings tend to increase. Every being which during its natural lifetime produces several eggs or seeds must suffer destruction during some period of its life, and during some season or occasional year, otherwise, on the principle of geometrical increase, its numbers would quickly become so inordinately great that no country could support the product. Hence, as more individuals are produced than can possibly survive, there must in every case be a struggle for existence, either one individual with another of the same species, or with the individuals of distinct species, or with the physical conditions of life. It is the doctrine of Malthus applied with manifold force to the whole animal and vegetable kingdoms; for in this case there can be no artificial increase of food, and no prudential restraint from marriage. Although some species may be now increasing more or less rapidly in numbers, all cannot do so, for the world would not hold them.

There is no exception to the rule that every organic being naturally increases at so high a rate that, if not destroyed, the earth would soon be covered by the progeny of a single pair. Even slow-breeding man has doubled in twenty-five years, and at this rate in less than a thousand years there would literally not be standing-room for his progeny.

Linnaeus has calculated that if an annual plant produced only two seeds--and there is no plant so unproductive as this--and their seedlings next year produced two, and so on, then in twenty years there would be a million plants. The elephant is reckoned the slowest breeder of all known animals, and I have taken some pains to estimate its probable minimum rate of natural increase; it will be safest to a.s.sume that it begins breeding when thirty years old and goes on breeding till ninety years old, bringing forth six young in the interval and surviving till one hundred years old; if this be so, after a period of from 740 to 750 years there would be nearly nineteen million elephants alive, descended from the first pair.

The struggle for life is most severe between individuals and varieties of the same species. As the species of the same genus usually have, though by no means invariably, much similarity in habits and const.i.tution, and always similarity in structure, the struggle will generally be more severe between them if they come into compet.i.tion with each other than between the species of distinct genera. We see this in the recent extension over parts of the United States of one species of swallow having caused the decrease of another species. The recent increase of the missel-thrush in parts of Scotland has caused the decrease of the song-thrush. How frequently we hear of one species of rat taking the place of another species under the most different climates! In Russia the small Asiatic c.o.c.kroach has everywhere driven before it its great congener. In Australia the imported hive-bee is rapidly exterminating the small, stingless native bee. We can dimly see why the compet.i.tion should be most severe between allied forms which fill nearly the same place in the economy of nature; but probably in no one case could we precisely say why one species has been victorious over another in the great battle of life.

A corollary of the highest importance may be deduced from the foregoing remarks, namely, that the structure of every organic being is related, in the most essential yet often hidden manner, to that of all the other organic beings with which it comes into compet.i.tion for food or residence or from which it has to escape or on which it preys. This is obvious in the structure of the teeth and talons of the tiger; and in that of the legs and claws of the parasite which clings to the hair on the tiger's body. But in the beautifully plumed seed of the dandelion, and in the flattened and fringed legs of the water-beetle, the relation seems at first confined to the elements of air and water. Yet the advantage of plumed seeds no doubt stands in the closest relations to the land being already thickly clothed with other plants; so that the seeds may be widely distributed and fall on unoccupied ground. In the water beetle, the structure of its legs, so well adapted for diving, allows it to compete with other aquatic insects, to hunt for its own prey, and to escape serving as prey to other animals.

The store of nutriment laid up within the seeds of many plants seems at first sight to have no sort of relation to other plants. But from the strong growth of young plants produced from such seeds, as peas and beans, when sown in the midst of long gra.s.s, it may be suspected that the chief use of the nutriment in the seed is to favor the growth of seedlings whilst struggling with other plants growing vigorously all around.

Look at a plant in the midst of its range; why does it not double or quadruple its numbers? We know that it can perfectly well withstand a little more heat or cold, dampness or dryness, for elsewhere it ranges into slightly hotter or colder, damper or drier, districts. In this case we can clearly see that if we wish in imagination to give the plant the power of increasing in number, we should have to give it some advantage over its compet.i.tors, or over the animals which prey upon it. On the confines of its geographical range, a change of const.i.tution with respect to climate would clearly be an advantage to our plant; but we have reason to believe that only a few plants or animals range so far, that they are destroyed exclusively by the rigor of the climate. Not until we reach the extreme confines of life, in the Arctic regions or on the borders of an utter desert, will compet.i.tion cease. The land may be extremely cold or dry, yet there will be compet.i.tion between some few species, or between the individuals of the same species, for the warmest or dampest spots.

Hence we can see that when a plant or an animal is placed in a new country amongst new compet.i.tors, the conditions of its life will generally be changed in an essential manner, although the climate may be exactly the same as in its former home. If its average numbers are to increase in its new home, we should have to modify it in a different way to what we should have had to do in its native country; for we should have to give it some advantage over a different set of compet.i.tors or enemies.

It is good thus to try in imagination to give to any one species an advantage over another. Probably in no single instance should we know what to do. This ought to convince us of our ignorance on the mutual relations of all organic beings, a conviction as necessary as it is difficult to acquire. All that we can do is to keep steadily in mind that each organic being is striving to increase in a geometrical ratio; that each at some period of its life, during some season of the year, during each generation or at intervals, has to struggle for life and to suffer great destruction. When we reflect on this struggle, we may console ourselves with the full belief that the war of nature is not incessant, that no fear is felt, that death is generally prompt, and that the vigorous, the healthy, and the happy survive and multiply.

3. Compet.i.tion, Specialization, and Organization[186]

Natural selection acts exclusively by the preservation and acc.u.mulation of variations, which are beneficial under the organic and inorganic conditions to which each creature is exposed at all periods of life. The ultimate result is that each creature tends to become more and more improved in relation to its conditions. This improvement inevitably leads to the gradual advancement of the organization of the greater number of living beings throughout the world.

But here we enter on a very intricate subject, for naturalists have not defined to each other's satisfaction what is meant by an advance in organization. Amongst the vertebrata the degree of intellect and an approach in structure to man clearly come into play. It might be thought that the amount of change which the various parts and organs pa.s.s through in their development from the embryo to maturity would suffice as a standard of comparison; but there are cases, as with certain parasitic crustaceans, in which several parts of the structure become less perfect, so that the mature animal cannot be called higher than its larva. Von Baer's standard seems the most widely applicable and the best, namely, the amount of differentiation of the parts of the same organic being, in the adult state, as I should be inclined to add, and their specialization for different functions; or, as Milne Edwards would express it, the completeness of the division of physiological labor. But we shall see how obscure this subject is if we look, for instance, to fishes, amongst which some naturalists rank those as highest which, like the sharks, approach nearest to amphibians; whilst other naturalists rank the common bony or teleostean fishes as the highest, inasmuch as they are most strictly fishlike and differ most from the other vertebrate cla.s.ses. We see still more plainly the obscurity of the subject by turning to plants, amongst which the standard of intellect is, of course, quite excluded; and here some botanists rank those plants as highest which have every organ, as sepals, petals, stamens, and pistils, fully developed in each flower; whereas other botanists, probably with more truth, look at the plants which have their several organs much modified and reduced in number as the highest.

If we take as the standard of high organization the amount of differentiation and specialization of the several organs in each being when adult (and this will include the advancement of the brain for intellectual purposes), natural selection clearly leads toward this standard; for all physiologists admit that the specialization of organs, inasmuch as in this state they perform their functions better, is an advantage to each being; and hence the acc.u.mulation of variations tending toward specialization is within the scope of natural selection.

On the other hand, we can see, bearing in mind that all organic beings are striving to increase at a high ratio and to seize on every unoccupied or less well-occupied place in the economy of nature, that it is quite possible for natural selection gradually to fit a being to a situation in which several organs would be superfluous or useless: in such cases there would be retrogression in the scale of organization.

But it may be objected that if all organic beings thus tend to rise in the scale, how is it that throughout the world a mult.i.tude of the lowest forms still exist; and how is it that in each great cla.s.s some forms are far more highly developed than others? Why have not the more highly developed forms everywhere supplanted and exterminated the lower? On our theory the continued existence of lowly organisms offers no difficulty for natural selection, or the survival of the fittest does not necessarily include progressive development--it only takes advantage of such variations as arise and are beneficial to each creature under its complex relations of life. And it may be asked what advantage, as far as we can see, would it be to an infusorian animalcule--to an intestinal worm, or even to an earthworm--to be highly organized. If it were no advantage, these forms would be left, by natural selection, unimproved or but little improved, and might remain for indefinite ages in their present lowly condition. And geology tells us that some of the lowest forms, as the infusoria and rhizopods, have remained for an enormous period in nearly their present state. But to suppose that most of the many low forms now existing have not in the least advanced since the first dawn of life would be extremely rash; for every naturalist who has dissected some of the beings now ranked as very low in the scale must have been struck with their really wondrous and beautiful organization.

Nearly the same remarks are applicable if we look to the different grades of organization within the same great group; for instance, in the vertebrata to the coexistence of mammals and fish; amongst mammalia to the coexistence of man and the ornithorhynchus; amongst fishes to the coexistence of the shark and the lancelet (Amphioxus), which later fish in the extreme simplicity of its structure approaches the invertebrate cla.s.ses. But mammals and fish hardly come into compet.i.tion with each other; the advancement of the whole cla.s.s of mammals, or of certain members in this cla.s.s, to the highest grade would not lead to their taking the place of fishes. Physiologists believe that the brain must be bathed by warm blood to be highly active, and this requires aerial respiration; so that warm-blooded mammals when inhabiting the water lie under a disadvantage in having to come continually to the surface to breathe. With fishes, members of the shark family would not tend to supplant the lancelet; for the lancelet, as I hear from Fritz Muller, has as sole companion and compet.i.tor on the barren sandy sh.o.r.e of South Brazil an anomalous annelid. The three lowest orders of mammals, namely, marsupials, edentata, and rodents, coexist in South America in the same region with numerous monkeys, and probably interfere little with each other.
