The psychological development involved in man's struggle along these lines may best be stated by an outline sketch of the character of his advance.
When I kill my prisoner (cannibalism was a very common characteristic of early man), it is in "human nature" to keep him for my own larder without sharing him. It is the extreme form of the use of force, the extreme form of human individualism. But putrefaction sets in before I can consume him (it is as well to recall these real difficulties of the early man, because, of course, "human nature does not change"), and I am left without food.
But my two neighbors, each with his butchered prisoner, are in a similar difficulty, and though I could quite easily defend my larder, we deem it better on the next occasion to join forces and kill one prisoner at a time. I share mine with the other two; they share theirs with me. There is no waste through putrefaction. It is the earliest form of the surrender of the use of force in favor of co-operation—the first attenuation of the tendency to act on impulse. But when the three prisoners are consumed, and no more happen to be available, it strikes us that on the whole we should have done better to make them catch game and dig roots for us. The next prisoners that are caught are not killed—a further diminution of impulse and the factor of physical force—they are only enslaved, and the pugnacity which in the first case went to kill them is now diverted to keeping them at work. But the pugnacity is so little controlled by rationalism that the slaves starve, and prove incapable of useful work. They are better treated; there is a diminution of pugnacity. They become sufficiently manageable for the masters themselves, while the slaves are digging roots, to do a little hunting. The pugnacity recently expended on the slaves is redirected to keeping hostile tribes from capturing them—a difficult matter, because the slaves themselves show a disposition to try a change of mastership. They are bribed into good behavior by better treatment: a further diminution of force, a further drift towards co-operation; they give labor, we give food and protection. As the tribes enlarge, it is found that those have most cohesion where the position of slaves is recognized by definite rights and privileges. Slavery becomes serfdom or villeiny. The lord gives land and protection, the serf labor and military service: a further drift from force, a further drift towards co-operation, exchange. With the introduction of money even the form of force disappears: the laborer pays rent and the lord pays his soldiers. It is free exchange on both sides, and economic force has replaced physical force. The further the drift from force towards simple economic interest the better the result for the effort expended. The Tartar khan, who seizes by force the wealth in his State, giving no adequate return, soon has none to seize. Men will not work to create what they cannot enjoy, so that, finally, the khan has to kill a man by torture in order to obtain a sum which is the thousandth part of what a London tradesman will spend to secure a title carrying no right to the exercise of force from a Sovereign who has lost all right to the use or exercise of physical force, the head of the wealthiest country in the world, the sources of whose wealth are the most removed from any process involving the exercise of physical force.
But while this process is going on inside the tribe, or group, or nation, force and hostility as between differing tribes or nations remain; but not undiminished. At first it suffices for the fuzzy head of a rival tradesman to appear above the bushes for primitive man to want to hit it. He is a foreigner: kill him. Later, he only wants to kill him if he is at war with his tribe. There are periods of peace: diminution of hostility. In the first conflicts all of the other tribe are killed—men, women, and children. Force and pugnacity are absolute. But the use of slaves, both as laborers and as concubines, attentuates this; there is a diminution of force. The women of the hostile tribe bear children by the conqueror: there is a diminution of pugnacity. At the next raid into the hostile territory it is found that there is nothing to take, because everything has been killed or carried off. So on later raids the conqueror kills the chiefs only (a further diminution of pugnacity, a further drift from mere impulse), or merely dispossesses them of their lands, which he divides among his followers (Norman Conquest type). We have already passed the stage of extermination.[54] The conqueror simply absorbs the conquered—or the conquered absorbs the conqueror, whichever you like. It is no longer the case of one gobbling up the other. Neither is gobbled. In the next stage we do not even dispossess the chiefs—a further sacrifice of physical force—we merely impose tribute. But the conquering nation soon finds itself in the position of the khan in his own State—the more he squeezes the less he gets, until, finally, the cost of getting the money by military means exceeds what is obtained. It was the case of Spain in Spanish America—the more territory she "owned" the poorer she became. The wise conqueror, then, finds that better than the exaction of tribute is an exclusive market—old English colonial type. But in the process of ensuring exclusiveness more is lost than is gained: the colonies are allowed to choose their own system—further drift from the use of force, further drift from hostility and pugnacity. Final result: complete abandonment of physical force, co-operation on basis of mutual profit the only relationship, with reference not merely to colonies which have become in fact foreign States, but also to States foreign in name as well as in fact. We have arrived not at the intensification of the struggle between men, but at a condition of vital dependence upon the prosperity of foreigners. Could England by some magic kill all foreigners, half the British population would starve. This is not a condition making indefinitely for hostility to foreigners; still less is it a condition in which such hostility finds its justification in any real instinct of self-preservation or in any deep-seated biological law. With each new intensification of dependence between the parts of the organism must go that psychological development which has marked every stage of the progress in the past, from the day that we killed our prisoner in order to eat him, and refused to share him with our fellow, to the day that the telegraph and the bank have rendered military force economically futile.
But the foregoing does not include all the facts, or all the factors. If Russia does England an injury—sinks a fishing fleet in time of peace, for instance—it is no satisfaction to Englishmen to go out and kill a lot of Frenchmen or Irishmen. They want to kill Russians. If, however, they knew a little less geography—if, for instance, they were Chinese Boxers, it would not matter in the least which they killed, because to the Chinaman all alike are "foreign devils"; his knowledge of the case does not enable him to differentiate between the various nationalities of Europeans. In the case of a wronged negro in the Congo the collective responsibility is still wider; for a wrong inflicted by one white man he will avenge himself on any other—American, German, English, French, Dutch, Belgian, or Chinese. As our knowledge increases, our sense of the collective responsibility of outside groups narrows. But immediately we start on this differentiation there is no stopping. The English yokel is satisfied if he can "get a whack at them foreigners"—Germans will do if Russians are not available. The more educated man wants Russians; but if he stops a moment longer, he will see that in killing Russian peasants he might as well be killing so many Hindoos, for all they had to do with the matter. He then wants to get at the Russian Government. But so do a great many Russians—Liberals, Reformers, etc. He then sees that the real conflict is not English against Russians at all, but the interest of all law-abiding folk—Russian and English alike—against oppression, corruption, and incompetence. To give the Russian Government an opportunity of going to war would only strengthen its hands against those with whom he was in sympathy—the Reformers. As war would increase the influence of the reactionary party in Russia, it would do nothing to prevent the recurrence of such incidents, and so quite the wrong party would suffer. Were the real facts and the real responsibilities understood, a Liberal people would reply to such an aggression by taking every means which the social and economic relationship of the two States afforded to enable Russian Liberals to hang a few Russian Admirals and establish a Russian Liberal Government. In any case, the realization of the fact attenuates hostility. In the same way, as they become more familiar with the facts, the English will attenuate their hostility to "Germans." An English patriot recently said, "We must smash Prussianism." The majority of Germans are in cordial agreement with him, and are working to that end. But if England went to war for that purpose, Germans would be compelled to fight for Prussianism. War between States for a political ideal of this kind is not only futile, it is the sure means of perpetuating the very condition which it would bring to an end. International hostilities repose for the most part upon our conception of the foreign State, with which we are quarrelling, as a homogeneous personality, having the same character of responsibility as an individual, whereas the variety of interests, both material and moral, regardless of State boundaries, renders the analogy between nations and individuals an utterly false one.
Indeed, when the co-operation between the parts of the social organism is as complete as our mechanical development has recently made it, it is impossible to fix the limits not merely of the economic interests, but of the moral interest of the community, and to say what is one community and what is another. Certainly the State limits no longer define the limits of the community; and yet it is only the State limits which international antagonism predicates. If the Louisiana cotton crop fails, a part of Lancashire starves. There is closer community of interest in a vital matter between Lancashire and Louisiana than between Louisiana and, say, Iowa, parts of the same State. There is much closer intercommunication between Britain and the United States in all that touches social and moral development than between Britain and, say, Bengal, part of the same State. An English nobleman has more community of thought and feeling with a European continental aristocrat (will marry his daughter, for instance) than he would think of claiming with such "fellow" British countrymen as a Bengal Babu, a Jamaica negro, or even a Dorset yokel. A professor at Oxford will have closer community of feeling with a member of the French Academy than with, say, a Whitechapel publican. One may go further, and say that a British subject of Quebec has closer contact with Paris than with London; the British subject of Dutch-speaking Africa with Holland than with England; the British subject of Hong Kong with Pekin than with London; of Egypt, with Constantinople than with London, and so on. In a thousand respects, association cuts across State boundaries, which are purely conventional, and renders the biological division of mankind into independent and warring States a scientific ineptitude.
Allied factors, introduced by the character of modern intercourse, have already gone far to render territorial conquest futile for the satisfaction of natural human pride and vanity. Just as in the economic sphere, factors peculiar to our generation have rendered the old analogy between States and persons a false one, so do these factors render the analogy in the sentimental sphere a false one. While the individual of great possessions does in fact obtain, by reason of his wealth, a deference which satisfies his pride and vanity, the individual of the great nation has no such sentimental advantage as against the citizen of the small nation. No one thinks of respecting the Russian mujik because he belongs to a great nation, or despising a Scandinavian or Belgian gentleman because he belongs to a small one; and any society will accord prestige to the nobleman of Norway, Holland, Belgium, Spain, or even Portugal, which it refuses to an American "Climber." The nobleman of any country will marry the noblewoman of another more readily than a woman from a lower class of his own country. The prestige of the foreign country rarely counts for anything in the matter, when it comes to the real facts of everyday life, so shallow is the real sentiment which now divides States. Just as in material things community of interest and relationship cut clear across State boundaries, so inevitably will the psychic community of interest come so to do.
Just as, in the material domain, the real biological law, which is association and co-operation between individuals of the same species in the struggle with their environment, has pushed men in their material struggle to conform with that law, so will it do so in the sentimental sphere. We shall come to realize that the real psychic and moral divisions are not as between nations, but as between opposing conceptions of life. Even admitting that man's nature will never lose the combativeness, hostility, and animosity which are so large a part of it (although the manifestations of such feelings have so greatly changed within the historical period as almost to have changed in character), what we shall see is the diversion of those psychological qualities to the real, instead of the artificial, conflict of mankind. We shall see that at the bottom of any conflict between the armies or Governments of Germany and England lies not the opposition of "German" interests to "English" interests, but the conflict in both States between democracy and autocracy, or between Socialism and Individualism, or reaction and progress, however one's sociological sympathies may classify it. That is the real division in both countries, and for Germans to conquer English, or English Germans, would not advance the solution of such a conflict one iota; and as such conflict becomes more acute, the German individualist will see that it is more important to protect his freedom and property against the Socialist and trade unionist, who can and do attack them, than against the British Army, which cannot. In the same way the British Tory will be more concerned with what Mr. Lloyd George's Budgets can do than with what the Germans can do.[55] From the realization of these things to the realization on the part of the British democrat that what stands in the way of his securing for social expenditure enormous sums, that now go to armaments, is mainly a lack of co-operation between himself and the democrats of a hostile nation who are in a like case, is but a step, and a step that, if history has any meaning, is bound shortly to be taken. When it is taken, property, capital, Individualism will have to give to its international organization, already far-reaching, a still more definite form, in which international differences will play no part. And when that condition is reached, both peoples will find inconceivable the idea that artificial State divisions (which are coming more and more to approximate to mere administrative divisions, leaving free scope within them or across them for the development of genuine nationality) could ever in any way define the real conflicts of mankind.
There remains, of course, the question of time; that these developments will take "thousands" or "hundreds" of years. Yet the interdependence of modern nations is the growth of little more than fifty years. A century ago England could have been self-supporting, and little the worse for it. One must not overlook the Law of Acceleration. The age of man on the earth is placed variously at from thirty thousand to three hundred thousand years. He has in some respects developed more in the last two hundred years than in all the preceding ages. We see more change now in ten years than originally in ten thousand. Who shall foretell the developments of a generation?
