So to those who clamor, as many now do, "Produce! Produce!" one simple question may be addressed:--"Produce what?" Food, clothing, house-room, art, knowledge? By all means! But if the nation is scantily furnished with these things had it not better stop producing a good many others which fill shop windows in Regent Street? If it desires to re-equip its industries with machinery and its railways with wagons, had it not better refrain from holding exhibitions designed to encourage rich men to re-equip themselves with motor-cars? What can be more childish than to urge the necessity that productive power should be increased, if part of the productive power which exists already is misapplied? Is not _less_ production of futilities as important as, indeed a condition of, _more_ production of things of moment? Would not "Spend less on private luxuries" be as wise a cry as "produce more"? Yet this result of inequality, again, is a phenomenon which cannot be prevented, or checked, or even recognized by a society which excludes the idea of purpose from its social arrangements and industrial activity. For to recognize it is to admit that there is a principle superior to the mechanical play of economic forces, which ought to determine the relative importance of different occupations, and thus to abandon the view that all riches, however composed, are an end, and that all economic activity is equally justifiable. {40} The rejection of the idea of purpose involves another consequence which every one laments, but which no one can prevent, except by abandoning the belief that the free exercise of rights is the main interest of society and the discharge of obligations a secondary and incidental consequence which may be left to take care of itself. It is that social life is turned into a scene of fierce antagonisms and that a considerable part of industry is carried on in the intervals of a disguised social war. The idea that industrial peace can be secured merely by the exercise of tact and forbearance is based on the idea that there is a fundamental identity of interest between the different groups engaged in it, which is occasionally interrupted by regrettable misunderstandings. Both the one idea and the other are an illusion. The disputes which matter are not caused by a misunderstanding of identity of interests, but by a better understanding of diversity of interests. Though a formal declaration of war is an episode, the conditions which issue in a declaration of war are permanent; and what makes them permanent is the conception of industry which also makes inequality and functionless incomes permanent. It is the denial that industry has any end or purpose other than the satisfaction of those engaged in it.
