It must further be noticed that all our ignorances, follies, and mistakes lessen the supporting power of the land. They do not prevent numbers from being born, but they lessen the fund on which those who are born must live, or they prevent us from winning and enjoying what the means at our disposal are really able to produce. All discord, quarreling, and war in a society have this effect. It is legitimate to think of Nature as a hard mistress against whom we are maintaining the struggle for existence. All our science and art are victories over her, but when we quarrel amongst ourselves we lose the fruits of our victory just as certainly as we should if she were a human opponent. All plunder and robbery squander the fund which has been produced by society for the support of society. It makes no difference whether the plunder and robbery are legal or illegal in form. Every violation of security of property and of such rights as are recognized in society has the same effect. All mistakes in legislation, whether sincere and innocent or dictated by selfish ambition and sordid greed, have the same effect. They rob the people of goods that were fairly theirs upon the stage of civilization on which they stood. All abuses of political power, all perversion of institutions, all party combinations for anti-social ends have the same effect. All false philosophies and mistaken doctrines, although it may take a long time to find out which ones are false, still have the same effect. They make us cast away bread and seize a stone.
All the old institutions which have outlived their usefulness and become a cover for abuses and an excuse for error, so that the wars and revolutions which overthrow them are a comparative good, must also be regarded as dogs which fetter us in our attempts to grasp what our knowledge and labor have brought within our reach. In short, all these evils and errors bring upon us penalties which consist in this: that while with the amount of land at our disposal, its productiveness being what it is, and the power of our arts being what it is, and our numbers being what they are, we might reach a certain standard of well-being, yet we have fallen short of it by just so much as the effect of our ignorances, follies, and errors may be. We can express the effect of our mis-doing and mis-thinking by regarding it as so much subtracted from the resources and apparatus with which we are carrying on the struggle for existence. We make the mistakes, in large part, because we cannot convince ourselves what is error and what is truth. The element of loss and penalty which I have described is the true premium which is offered us for finding out where the truth lies. The greatest good we can expect from our scientific investigations and from our education is to free us from these errors and to save us from these blunders. In this view, it is certain that a correct apprehension of social facts and laws would advance the happiness of mankind far more than any discovery of truth about the order of physical nature which we could possibly make.
From one point of view, history may be regarded as showing the fluctuations in the ratio of the population to the land. The population of Greece underwent a very great reduction, during the three centuries before the Christian era, from the numbers which lived in great prosperity in the heroic period of the fifth century before Christ. The reasons for this have never been very satisfactorily ascertained, but it may have been through the laziness and general worthlessness of the population. The population of the Italian peninsula decreased at a high ratio during the period of the Roman empire, and great areas of land went out of cultivation. The Roman system, after stimulating the whole Roman world to high prosperity by giving peace and security, next used up and exhausted the whole world, including Italy. In western Europe, the cultivated area and the population increased and decreased together during the whole feudal period, according as anarchy and violence or peace and security prevailed for periods and over areas. We may regard the maintenance of a great number in high comfort on a given area as the standard towards which success in solving economic and social problems is carrying us, or from which we are falling away when we fail to solve the problems of the time correctly. Taking wide sweeps of history, it is possible to see the "tides in the affairs of men" which are marked by these ebbs and flows of the population against the areas of waste land.
It was the existence of waste land in the countries of western Europe during the Middle Ages that was all the time influencing the fate of the servile classes. The waste had high importance in the manor system; but as slow improvements were brought about in agriculture, the importance of the waste declined. The lord desired to increase his income by reducing it to tillage, and for this purpose he created tenures upon it on behalf of young men of the servile class, the terms of which were easier than those of the ancient and traditional tenures; or he allowed tenants to create petty holdings out of the waste on special terms which gave them a chance to win capital. However slight the claims were which the servile classes had upon the waste by law and custom, nevertheless the mass of wild land existing in and through the country was in fact a patrimony of theirs; its economic effect upon their status and future was a thing which no laws or customs could cut off. The wars, famines, and pestilences which decimated their ranks were a blessing to those who survived and who found themselves possessed of a monopoly of labor over against a superabundance of land. That is the economic status which gives the laborer control of the market and command of the situation.
It was this state of things which freed the servile classes of France, England, and northern Italy. An advance in the arts by several great inventions greatly assisted the movement. The rise of the dynastic states, establishing civil institutions with greater security, peace, and order, worked in the same direction. The Church had been preaching doctrines for a dozen centuries which were distinctly unfavorable to servitude, and which did avail to produce conscientious misgivings and erratic acts hostile to servitude. The influence of these teachings is not to be denied, but it was trifling compared with the great economic changes which have been mentioned, in bringing about the emancipation of the servile classes. Here we have the reason for the earth hunger of the mass of mankind. It is that the condition of things which favors the masses, always assuming that the guarantees of peace and order allow of industrial development, is one in which the area of land is large in proportion to the population. The servile classes contributed little to their own emancipation except a dull and instinctive pushing or shirking by which they were enabled to win whatever amelioration of their status the changes in motion might bring to them. Often their prejudices, ignorance, and stupidity led them to oppose their own interest and welfare. It was the educated and middle classes which, by thought and teaching, wrought out all the better knowledge and, so far as human wit had anything to do with it—which indeed was not to any great extent—broke the way for a new order of things; and these classes, too, acted in general selfishly or short-sightedly.
In any true philosophy of the great social changes, especially the emancipation of the servile classes at the end of the Middle Ages in the leading nations of western Europe, we must look upon the new power of production of the means of subsistence from the soil, in proportion to the numbers who were to share it, as the true explanation of those changes. The living men had won new power, new command over the conditions of life. They might abuse or waste that power, but when they had it, their greater welfare could be no great mystery. The expansion of life in every social domain did upset ideas and philosophies. It produced a religious and ecclesiastical revolution and entailed upon the civilized world religious wars which produced a vast squandering of the new power—for all history teaches us that it is idle to hope that added power will be employed simply to go forward to simple and direct blessing of mankind. On the contrary, men are sure to go to fighting over it in one relation or another. The sixteenth and seventeenth centuries were full of wars which are interpreted in one way or another according to their immediate aspects, but which really were struggles of men, families, classes, and parties for the possession, control, and advantage of the new economic power. It is, however, a great and instructive fact to notice that, although the labor class knew least about the case, had least share in it, and were least considered by the active parties in it, they won the most by it. Everybody was working for them, not out of love for them, or out of intention, but because it was not possible to help it.
Here we must be on our guard against a fallacy which is almost universal in connection with this matter. It is constantly denied, especially by reformers and revolutionists,
