To work nine hours instead of ten, and eight instead of nine, was only apparently an encroachment on the industrial work. The worldwide experiment has proved that the shorter working hours allow an intensity of strain and an improvement of the workmen which ultimately heighten the value of the output. The safety devices burdened the manufacturer with expenses, and yet the economist knows that no outlay is more serviceable for the achievement of the factory. Unionism and arbitration treaties are sincere and momentous efforts to help the whole industrial nation. And all this may be only the beginning. The time may really come when every healthy man will serve his year in the industrial army. Man and woman and child may thus be more and more protected against the destructive abuses of our economic scheme. Their physical health and their mental energy may be kept in better and better working order by social reforms, by state measures and strong organization. The fear of the future, that greatest destroyer of the labourer's working mood, may be more and more eliminated. Extremely much still remains to be done, but the best of it can surely be done without giving up the idea of private capital. In the framework of the capitalistic order such reforms mean a national scientific management in the interest of efficiency and success. If that framework is destroyed, the vigour and the energy are lost, and no improvements in the detail can patch up the ruinous weakness in the foundation. If the goal is an increased achievement of the industrialized nation, socialism is bound to be a failure as long as human minds and their motives are what they are to-day and what they have been through the last five thousand years. No doubt such arguments have little weight with the larger number of those who come to the defence of socialism. The purpose, they would say, is not at all to squeeze more work out of the nerves and muscles of the labourer, to fill still more the pocket of the corporations, to produce still more of the infernal noise in the workshops of the world. The real aim has nothing to do with the output and the muscle, but with the joy and happiness of the industrial workers, who have become slaves in the capitalistic era. It is quite true that if this is the end, the arguments which speak against the efficiency of socialism might well be disregarded. The mixing of the reasons can bring only confusion, and such chaos is unavoidable indeed, as long as the aims are not clearly discriminated. We may acknowledge frankly that the socialistic order may be a hindrance to highest efficiency, and yet should be welcomed because it would abolish the sources of unhappiness. Yet is there really any hope for such a paradise? The problem of achievement may stand nearer to the economist, but that of happiness and misery is thoroughly a question of the mind, and it is the duty of the psychologist to take a stand.
