Social evolution, wiser and more practical than we, has met the necessities of the case by developing those organic tendencies in man which urge him to his social activities, and that always-increasing fund of social nutrition and social energy which enables him to do his work. The difference between an architect dreaming great buildings and eager to build them and an animal struggling for his food, is as the difference between the action of the heart and the action of a hungry fox. The fox exerts himself to supply his wants, the heart exerts itself as a functional activity it cannot help and without any reference to its wants. Its wants are supplied, to be sure, but not in measured dole related to its activities. The exertions of the heart bear relation to the need of the organism to which it belongs, not to its own appetite. If you have to run, your heart works harder; it had no need of extra work, but _you_ had, and, being an organ, it performed the work. Man’s work is called for by the social demands. Society needs Commerce, and Commerce is developed. Society needs Art, and Art is developed. But man, being a self-conscious individual, had to be convinced from without as well as urged from within, else he stoutly refused to perform his social service. “Why should I,” he asks, “if it does not benefit me? A man works only to get something.” Before he had got even this far in formulating his objection to work, he was forced to it, as we have seen, by the slave system and effectually coerced. To meet this later attitude of refusal he was forced to it by the wage system, and effectually coerced as before. In the first case the anti-social results of that form of labour have led to its being discarded, and in the second case we are rapidly approaching the same conclusion. Social service performed under the persuasion of self-interest is accompanied by so many deleterious and anti-social phenomena that it is high time we adopted a wiser system. When exertion is recognised as a racial necessity and a high individual pleasure, there is no longer any weight to the first clause of the Want theory. When it is shown that our desires are gratified by the exertion of others exclusively, there is no longer any weight to the second. And when it is shown that the required “exertion” is not an exertion at all, but a relief, a mere letting off of the social steam pressure, the Want theory begins to need a historian to explain it. The only really confusing element lies in the system of exchange now in use, the wage system, and will be taken up in the chapter on Distribution. X: THE NATURE OF WORK (II) _Summary_
