50. Galton estimated the number of men of genius in all history at four hundred. An important fraction of these were related by blood. The "men of the time" he rates at four hundred and fifty in a million, and the more distinguished of them at two hundred and fifty in a million. These latter he defines by saying that a man, to be included amongst them, "should have distinguished himself pretty frequently, either by purely original work, or as a leader of opinion." He finds that illustrious men are only one in a million. On the other hand, idiots and imbeciles in England and Wales are one in four hundred, of whom thirty per cent can be educated so as to be equal to one third of a normal man each; forty per cent can be made worth two thirds of a man; twenty-five or thirty per cent pass muster in a crowd. Above these are silly persons whose relatives shield them from public knowledge. Then above these come the Dundreary type.69
51. Class; race; group solidarity. If the group which is classified is a large one, and especially if it is a genetic unit (race, tribe, or nation), there are no gaps in the series. Each individual falls into his place by virtue of his characteristic differences. Just as no two are anthropologically alike, so we may believe that no two are alike or equal in societal value. That all men should be alike or equal, by any standard whatever, is contrary to all the facts of human nature and all the conditions of human life. Any group falls into subdivisions, the members of each of which are approximately equal, when measured by any standard, because the classification is imperfect. If we make it more refined, the subdivisions must be subdivided again. We are in a dilemma: we cannot describe mankind at all without categories, and if we go on to make our categories more and more exact, each one of them would at last contain only one person. Two things result which are practically important, and which furnish us with scientific concepts which we can employ in further study: (1) The classification gives us the notion of the relative position of one, or a subdivision, in the entire group. This is the sense of "class."70 (2) The characteristic differences furnish the notion of individuality and personality. The concept of a race, as the term is now used, is that of a group clustered around a mean with respect to some characteristic, and great confusion in the use of the word "race" arises from the attempt to define races by their boundaries, when we really think of them by the mean or mode, e.g. as to skin color. The coherence, unity, and solidarity of a genetic group is a very striking fact. It seems to conceal a play of mystic forces. It is, in fact, no more mysterious than the run of dice. The propositions about it would all become, in the last analysis, identical propositions; e.g. it is most probable that we shall meet with the thing which is present in the greatest number; or, it is most probable that the most probable thing will happen. In the middle of the nineteenth century, when attention was first called to the solidarity and internal correlations of groups, especially if they were large and genetic, it was believed that occult and far-reaching laws had been discovered. That opinion has long been abandoned. If there are four dice in a box, each having from one to six dots on its faces, the chance of throwing four sixes is just the same as that of throwing four ones. The mean of the sums of the dots which may fall uppermost is fourteen, which can be produced by one hundred and forty-six throws. Suppose that the components of social value are four—intellectual, moral, physical, economic—represented by the four dice, and that the degrees are represented by the dots. We should get four sixes once in twelve hundred and ninety-six throws. Of the one hundred and forty-six throws which give the mean fourteen, seventy-two show one six up. That might be a Hercules fit only for a dime museum. Seventy-eight of the combinations are inharmonious, but have one strong element.71 In societal matters it is by no means indifferent whether the equal sums of societal value are made up of very unequal, or of harmonious, components. So in a group of a million persons the chance of a great genius, who would stand alone towards X is just the same as that of an utter idiot who would stand alone towards x, and the reason why the number at the mode is so great is that the societal value is the sum of components, of which many sums may be equal, although the components are very unequal. Two strata at equal distances above and below O are equal in number, so far as their useful powers and resistances go, but education introduces a new component which destroys their equality and forces a redistribution. Galton72 suggests that, if people who would when adults fall in classes V, W, or X in our diagram could be recognized in infancy, and could be bought for money, it would be a great bargain for a nation, England for instance, to buy them for much money and rear them as Englishmen. Farr estimated the baby of an agricultural laborer as worth £5, capital value. A baby who could be reared to take a place in the class X would have a capital value of thousands of pounds. The capital value would be like that of land of different degrees of natural advantage, but none of it yet exploited.
52. The masses and the mores. In connection with the mores the masses are of very great importance. The historical or selected classes are those which, in history, have controlled the activities and policy of generations. They have been differentiated at one time by one standard, at another time by another. The position which they held by inheritance from early society has given them prestige and authority. Merit and societal value, according to the standards of their time, have entered into their status only slightly and incidentally. Those classes have had their own mores. They had the power to regulate their lives to some extent according to their own choice, a power which modern civilized men eagerly desire and strive for primarily by the acquisition of wealth. The historical classes have, therefore, selected purposes, and have invented ways of fulfilling them. Their ways have been imitated by the masses. The classes have led the way in luxury, frivolity, and vice, and also in refinement, culture, and the art of living. They have introduced variation. The masses are not large classes at the base of a social pyramid; they are the core of the society. They are conservative. They accept life as they find it, and live on by tradition and habit. In other words, the great mass of any society lives a purely instinctive life just like animals. We must not be misled by the conservatism of castes and aristocracies, who resist change of customs and institutions by virtue of which they hold social power. The conservatism of the masses is of a different kind. It is not produced by interests, but it is instinctive. It is due to inertia. Change would make new effort necessary to win routine and habit. It is therefore irksome. The masses, moreover, have not the power to reach out after "improvements," or to plan steps of change by which needs might be better satisfied. The mores of any society, at a period, may be characterized by the promptness or reluctance of the masses to imitate the ways of the classes. It is a question of the first importance for the historian whether the mores of the historical classes of which he finds evidence in documentary remains penetrated the masses or not. The masses are the real bearers of the mores of the society. They carry tradition. The folkways are their ways. They accept influence or leadership, and they imitate, but they do so as they see fit, being controlled by their notions and tastes previously acquired. They may accept standards of character and action from the classes, or from foreigners, or from literature, or from a new religion, but whatever they take up they assimilate and make it a part of their own mores, which they then transmit by tradition, defend in its integrity, and refuse to discard again. Consequently the writings of the literary class may not represent the faiths, notions, tastes, standards, etc., of the masses at all. The literature of the first Christian centuries shows
