Respecting the essential causes of this social transformation, it must suffice to say that it results from certain general traits in human beings, joined with the influences of their varying circumstances.
Every man aims to pass from desire to satisfaction with the least possible hindrance—follows the line of least resistance. Either the shortest path, or the path which presents fewest impediments, is that which he chooses; and the like applies to courses of conduct at large: he does not use great effort to satisfy a want when small effort will do. Given his surroundings and the occupation he chooses, when choice is possible, is that which promises a satisfactory livelihood with the least tax on such powers as he has, bodily and mental—is the easiest to his particular nature, all things considered. What holds of individuals holds of masses of individuals; and hence the inhabitants of a tract offering facilities for a particular occupation fall into that occupation. In § 732 of the Principles of Sociology I have given from various countries illustrations of the ways in which local conditions determine the local industries:—instance among ourselves mining districts where there are coal, ironstone, lead, slate; wheat-growing districts and pastoral districts; fruit and hop districts; districts for weavers, stockingers, workers in iron; places for shipbuilding, importing, fishing, etc.: showing that certain sections of the population become turned into organizations for the production of certain commodities, without reference to the directive agency of any man. So in each case is it with the various classes of merchants, shopkeepers, professional men, etc., who in each of these centers minister to those engaged in its special industries: nobody ordering them to come or to go.
Similarly when we pass from production to distribution. As in India at the present time, where a Juggernaut festival is accompanied by a vast fair; as, according to Curtius and Mommsen, in Greece and Rome, the gatherings of people to make sacrifices to the gods were the occasions for trading; so in Christian times, church festivals and saints' days, drawing assemblages of people for worship, led to active exchange of commodities—the names of the fairs proving their origin. This was not arranged by any one: it arose from the common sense of all who wanted to sell some things and buy others. There has been a like history for the rise of markets, and the transition from weekly to bi-weekly, and finally to daily, markets in respect of important things—corn, money, securities. No superior man, political or other, dictated these developments. When barter gave place to exchange by means of a currency, the like happened. One wanting to dispose of surplus goods, meeting those who had no personal need for such goods, took in exchange certain things in universal demand, which he knew he would be able to pass on in like manner—in early stages articles of food, of warmth, of defense, of ornament; and from such articles arose in each case a currency—here dried fish, there tea-bricks, and in other cases skins, bundles of cotton, here standard bars of rock salt, there standard bars of iron, in one place definite lengths of cloth, and in another fine mats, and in many places ornaments and the materials for ornaments: which last, gold and silver, being relatively portable, passed into wide use. These precious metals were at first in quantities actually weighed; then in quantities of professed weight; and finally in quantities bearing the king's stamp as being the most trustworthy. No great man—political, industrial, or other—invented this system. It has everywhere resulted from men's efforts to satisfy their needs in the easiest ways. So was it with the transition from a currency of intrinsic value to one of representative value. When, instead of a direct payment in coin, there came to be used a memorandum of indebtedness to be presently discharged, which could be transferred to others—when, as in Italy, to save the weighing and testing of miscellaneous coins, there arose the practice of depositing specified quantities with a custodian and having from him negotiable receipts—when, as in England, the merchants, after having been robbed by the king of their valuables, left for security in the Tower, sought safer places, and, depositing them in the vaults of goldsmiths, received in return "goldsmiths' notes," which could pass from hand to hand; there was initiated a paper-currency. Goldsmiths developed into bankers; after central banks there arose provincial banks; promises to pay became to a great extent substitutes for actual payments; and presently grew up the supplementary system of checks, extensively serving in place of coin and notes. Finally, bank-clerks in London, instead of presenting to the respective banks the many and various claims upon them, met and exchanged these claims and settled the balance: whence presently came the clearing house. No superior man arranged all this. Each further stage was prompted by the desire to economize labor. From primitive fairs up to the daily transactions of the money market, distribution and exchange have developed without the dictation of any great man, either of Mr. Carlyle's sort or of Mr. Mallock's sort. It has been so throughout all other arrangements subserving national life, even the governmental. Though here at least it seems that the individual will and power play the largest part, yet it is otherwise. I do not merely refer to the fact that without loyalty in citizens a ruler can have no power; and that so the supremacy of a man intrinsically or conventionally great is an outcome of the average nature; but I refer to the fact that governmental evolution is essentially a result of social necessities. On tracing its earliest stages from savage life upwards, it becomes manifest that even a ministry is not the mere invention of a king. It arises everywhere from that augmentation of business which goes along with increase of territory and authority: entailing the necessity for deputing more and more work. Under its special aspect it seems to be wholly a result of the king's private action, but under its general aspect it is seen to be determined by the conditions of his existence. And it is so with governmental institutions at large. Without tracing these further it will suffice to quote the saying of Macintosh—"Constitutions are not made but grow."
Of course inequalities of nature and consequent inequalities of relative position are factors in social changes. Of course, as implied above, any assertion of the approximate equality of human beings, save in the sense that they are beings having sets of faculties common to them all, is absurd; and it is equally absurd to suppose that the unlikenesses which exist are without effects on social life. I have pointed out that in the earliest stages of social evolution, when war is the business of life, the supremacy of a leader or chief, or primitive king, is a fact of cardinal importance; and also that the initiator of ecclesiastical control is necessarily distinguished from others "by knowledge and intellectual capacity." The beginnings of industrial evolution are also ascribed by me to differences of individual capacity; as instance the following quotations from that part of the Principles of Sociology which deals with Industrial Institutions.
The natural selection of occupations has for its primary cause certain original differences between individuals, partly physical, partly psychical. Let us for brevity's sake call this the physio-psychological cause (§ 730).
That among the fully civilized there are in like manner specializations of function caused by natural aptitudes, needs no showing: professions and crafts are often thus determined ... occupations of relatively skilled kinds having fallen into the hands of the most intelligent (§ 731).
Speaking generally, the man who, among primitive peoples, becomes ruler, is at once a man of power and a man of sagacity: his sagacity being in large measure the cause of his supremacy. We may therefore infer that as his political rule, though chiefly guided by his own interests, is in part guided by the interests of his people, so his industrial rule, though having for its first end to enrich himself, has for its second end the prosperity of industry at large. It is a fair inference that on the average his greater knowledge expresses itself in orders which seem, and sometimes are, beneficial (§ 770).
In its beginnings slavery commonly implies some kind of inferiority (§ 795).
Considered as a form of industrial regulation, slavery has been natural to early stages of conflicts and consolidations (§ 800).
The rise of slavery exhibits in its primary form the differentiation of the regulative part of a society from the operative part (§ 798).
The recognition of these effects of individual differences, especially in early stages, may rightly go along with the assertion that all the large traits of social structure are otherwise determined—that all those great components of a society which carry on the various industries, making the life of the whole possible, all those specialized classes which have established and maintained the inter-dependence of the producing structures, by facilitating and regulating the exchange of their products, have arisen from the play of aggregate forces, constituted of men's desires directed by their respective sets of circumstances. Mr. Mallock alleges that the great fact of human inequality—the fact that there is a minority "more gifted and efficient than the majority"—is the fundamental fact from which "the main structural characteristics of all civilized societies spring."[10] That he should assert this in presence of all the evidence which the Principles of Sociology puts before him, is, to use the weakest word, surprising. If his assertion be true, however, the way of demonstrating its truth lies open before him. In volumes II. and III. of the Principles of Sociology, several groups of institutions, presented by every developed society, are dealt with under the heads, Political, Ecclesiastical, Professional, Industrial: seventy-one chapters being included in them. Each chapter treats of some aspect, some division or subdivision, of the phenomena grouped under the general head. Instead of the Industrial Institutions discussed above, suppose that Mr. Mallock takes a group not touched upon—Professional Institutions. The thesis worked out in the part so entitled is that all the professions are differentiated from the priesthood; and the differentiation is tacitly represented as due to the slow operation of those natural causes which lead to specializations of function throughout the whole social aggregate. If Mr. Mallock is right, then of the chapters dealing with the ten professions enumerated, each is wrong by omitting to say anything about the great man, political, industrial, or other, who set up the differentiation or from time to time consciously gave it a more pronounced character—who thought that it would be well that there should be a separate medical class, or a separate teaching class, or a separate artist class, and then carried his thought into effect. Mr. Mallock's course is simply to take each of these chapters and show how, by the recognition of the supplementary factor on which he insists, the conclusions of the chapter are transformed. If he does this he will do more than by merely asserting that my views of social evolution are wrong because the "great fact of human inequality" "is systematically and ostentatiously ignored."
If in his title Mr. Mallock had, instead of "Evolution," written Social Sustentation, the general argument of his book would have been valid. If, further, he had alleged that social sustentation is instrumental to social evolution, and that in the absence of processes facilitating social sustentation social evolution can not take place, no one could have gainsaid his conclusion. And if he had inferred that whoever improves these processes betters the conditions which favor social evolution, his inference would have been true. But this admission may be made without admitting that the men who directly or indirectly further sustentation, or who improve the quality of the social units, are the agents who determine and direct social evolution. An account of their doings in no way constitutes an account of that social transformation from an indefinite incoherent homogeneity to a definite coherent heterogeneity, in which the evolution of a society essentially consists.
