Given the same innate capacity, and it is evident that social development will go on faster or slower, will stop or turn back, according to the resistances it meets. In a general way these obstacles to improvement may, in relation to the society itself, be classed as external and internal—the first operating with greater force in the earlier stages of civilization, the latter becoming more important in the later stages.
Man is social in his nature. He does not require to be caught and tamed in order to induce him to live with his fellows. The utter helplessness with which he enters the world, and the long period required for the maturity of his powers, necessitate the family relation; which, as we may observe, is wider, and in its extensions stronger, among the ruder than among the more cultivated peoples. The first societies are families, expanding into tribes, still holding a mutual blood relationship, and even when they have become great nations claiming a common descent.
Given beings of this kind, placed on a globe of such diversified surface and climate as this, and it is evident that, even with equal capacity, and an equal start, social development must be very different. The first limit or resistance to association will come from the conditions of physical nature, and as these greatly vary with locality, corresponding differences in social progress must show themselves. The net rapidity of increase, and the closeness with which men, as they increase, can keep together, will, in the rude state of knowledge in which reliance for subsistence must be principally upon the spontaneous offerings of nature, very largely depend upon climate, soil, and physical conformation. Where much animal food and warm clothing are required; where the earth seems poor and niggard; where the exuberant life of tropical forests mocks barbarous man’s puny efforts to control; where mountains, deserts, or arms of the sea separate and isolate men; association, and the power of improvement which it evolves, can at first go but a little way. But on the rich plains of warm climates, where human existence can be maintained with a smaller expenditure of force, and from a much smaller area, men can keep closer together, and the mental power which can at first be devoted to improvement is much greater. Hence civilization naturally first arises in the great valleys and table lands where we find its earliest monuments.
But these diversities in natural conditions, not merely thus directly produce diversities in social development, but, by producing diversities in social development, bring out in man himself an obstacle, or rather an active counterforce, to improvement. As families and tribes are separated from each other, the social feeling ceases to operate between them, and differences arise in language, custom, tradition, religion—in short, in the whole social web which each community, however small or large, constantly spins. With these differences, prejudices grow, animosities spring up, contact easily produces quarrels, aggression begets aggression, and wrong kindles revenge.[62] And so between these separate social aggregates arises the feeling of Ishmael and the spirit of Cain, warfare becomes the chronic and seemingly natural relation of societies to each other, and the powers of men are expended in attack or defense, in mutual slaughter and mutual destruction of wealth, or in warlike preparations. How long this hostility persists, the protective tariffs and the standing armies of the civilized world to-day bear witness; how difficult it is to get over the idea that it is not theft to steal from a foreigner, the difficulty in procuring an international copyright act will show. Can we wonder at the perpetual hostilities of tribes and clans? Can we wonder that when each community was isolated from the others—when each, uninfluenced by the others, was spinning its separate web of social environment, which no individual can escape, that war should have been the rule and peace the exception? “They were even as we are.”
Now, warfare is the negation of association. The separation of men into diverse tribes, by increasing warfare, thus checks improvement; while in the localities where a large increase in numbers is possible without much separation, civilization gains the advantage of exemption from tribal war, even when the community as a whole is carrying on warfare beyond its borders. Thus, where the resistance of nature to the close association of men is slightest, the counterforce of warfare is likely at first to be least felt; and in the rich plains where civilization first begins, it may rise to a great height while scattered tribes are yet barbarous. And thus, when small, separated communities exist in a state of chronic warfare which forbids advance, the first step to their civilization is the advent of some conquering tribe or nation that unites these smaller communities into a larger one, in which internal peace is preserved. Where this power of peaceable association is broken up, either by external assaults or internal dissensions, the advance ceases and retrogression begins.
But it is not conquest alone that has operated to promote association, and, by liberating mental power from the necessities of warfare, to promote civilization. If the diversities of climate, soil, and configuration of the earth’s surface operate at first to separate mankind, they also operate to encourage exchange. And commerce, which is in itself a form of association or co-operation, operates to promote civilization, not only directly, but by building up interests which are opposed to warfare, and dispelling the ignorance which is the fertile mother of prejudices and animosities.
And so of religion. Though the forms it has assumed and the animosities it has aroused have often sundered men and produced warfare, yet it has at other times been the means of promoting association. A common worship has often, as among the Greeks, mitigated war and furnished the basis of union, while it is from the triumph of Christianity over the barbarians of Europe that modern civilization springs. Had not the Christian Church existed when the Roman Empire went to pieces, Europe, destitute of any bond of association, might have fallen to a condition not much above that of the North American Indians or only received civilization with an Asiatic impress from the conquering scimitars of the invading hordes which had been welded into a mighty power by a religion which, springing up in the deserts of Arabia, had united tribes separated from time immemorial, and, thence issuing, brought into the association of a common faith a great part of the human race.
Looking over what we know of the history of the world, we thus see civilization everywhere springing up where men are brought into association, and everywhere disappearing as this association is broken up. Thus the Roman civilization, spread over Europe by the conquests which insured internal peace, was overwhelmed by the incursions of the northern nations that broke society again into disconnected fragments; and the progress that now goes on in our modern civilization began as the feudal system again began to associate men in larger communities, and the spiritual supremacy of Rome to bring these communities into a common relation, as her legions had done before. As the feudal bonds grew into national autonomies, and Christianity worked the amelioration of manners, brought forth the knowledge that during the dark days she had hidden, bound the threads of peaceful union in her all-pervading organization, and taught association in her religious orders, a greater progress became possible, which, as men have been brought into closer and closer association and co-operation, has gone on with greater and greater force.
But we shall never understand the course of civilization, and the varied phenomena which its history presents, without a consideration of what I may term the internal resistances, or counter forces, which arise in the heart of advancing society, and which can alone explain how a civilization once fairly started should either come of itself to a halt or be destroyed by barbarians.
The mental power, which is the motor of social progress, is set free by association, which is, what, perhaps, it may be more properly called, an integration. Society in this process becomes more complex; its individuals more dependent upon each other. Occupations and functions are specialized. Instead of wandering, population becomes fixed. Instead of each man attempting to supply all of his wants, the various trades and industries are separated—one man acquires skill in one thing, and another in another thing. So, too, of knowledge, the body of which constantly tends to become vaster than one man can grasp, and is separated into different parts, which different individuals acquire and pursue. So, too, the performance of religious ceremonies tends to pass into the hands of a body of men specially devoted to that purpose, and the preservation of order, the administration of justice, the assignment of public duties and the distribution of awards, the conduct of war, etc., to be made the special functions of an organized government. In short, to use the language in which Herbert Spencer has defined evolution, the development of society is, in relation to its component individuals, the passing from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity. The lower the stage of social development, the more society resembles one of those lowest of animal organisms which are without organs or limbs, and from which a part may be cut and yet live. The higher the stage of social development, the more society resembles those higher organisms in which functions and powers are specialized, and each member is vitally dependent on the others.
