Even the complaint repeated without end that the workingman's task is unendurable because of its unceasing monotony is ultimately nothing but a psychological theory, and this theory is superficial and misleading. It is easy to point out to the suggestible mind that there is a wonderful enrichment of life in variety, and that uniformity must therefore be something ugly and discouraging and unworthy. But the real mental facts allow just as well the opposite argument. The mere change and variation, going from one thing to another, makes the mind restless and distracted, without inner unity and harmony. To be loyal to one task and to continue it faithfully and insistently, brings that perfect adjustment of the mind in which every new act is welcome because it has become the habit ingrained in the personality. To be sure there are individual differences. We have in political life, too, radicals who get more satisfaction from change, and conservatives who prefer continuity of traditions; and so the whole mental structure of some men is better adjusted to a frequent variation in work, and that of others better prepared for continuity. The one has a temperament which may lead him from one occupation to another, from one town to another, from one flat to another, from one set of companions to another. But there is the opposite type of minds. To them it is far more welcome to continue throughout life at the same work, in the same old home, in touch with the same dear friends. Many minds surely are better fitted for alternation in their activities, but many others, and they certainly are not the worst, are naturally much better adapted to a regular repetition. There are opportunities for both types of mental behaviour in the workshop of the nation, and the peaceful adjustment is disturbed only by the hasty theory that repetition is a lower class of work, which makes man a mere machine and that it is therefore to be despised. Change the theory about uniformity, and you remove monotony from the industrial world. Monotony is only the uniformity which is hated.
