If the other conditions that we have postulated can be realized, it seems almost certain that there must be less illness than there is at present. Population will no longer be congested in slums; children will have far more of fresh air and open country; the hours of work will be only such as are wholesome, not excessive and exhausting as they are at present. As for the progress of science, that depends very largely upon the degree of intellectual liberty existing in the new society. If all science is organized and supervised by the State, it will rapidly become stereotyped and dead. Fundamental advances will not be made, because, until they have been made, they will seem too doubtful to warrant the expenditure of public money upon them. Authority will be in the hands of the old, especially of men who have achieved scientific eminence; such men will be hostile to those among the young who do not flatter them by agreeing with their theories. Under a bureaucratic State Socialism it is to be feared that science would soon cease to be progressive and acquired a medieval respect for authority. But under a freer system, which would enable all kinds of groups to employ as many men of science as they chose, and would allow the ``vagabond's wage'' to those who desired to pursue some study so new as to be wholly unrecognized, there is every reason to think that science would flourish as it has never done hitherto.[61] And, if that were the case, I do not believe that any other obstacle would exist to the physical possibility of our system. [61] See the discussion of this question in the preceding chapter. The question of the number of hours of work necessary to produce general material comfort is partly technical, partly one of organization. We may assume that there would no longer be unproductive labor spent on armaments, national defense, advertisements, costly luxuries for the very rich, or any of the other futilities incidental to our competitive system. If each industrial guild secured for a term of years the advantages, or part of the advantages, of any new invention or methods which it introduced, it is pretty certain that every encouragement would be given to technical progress. The life of a discoverer or inventor is in itself agreeable: those who adopt it, as things are now, are seldom much actuated by economic motives, but rather by the interest of the work together with the hope of honor; and these motives would operate more widely than they do now, since fewer people would be prevented from obeying them by economic necessities. And there is no doubt that intellect would work more keenly and creatively in a world where instinct was less thwarted, where the joy of life was greater, and where consequently there would be more vitality in men than there is at present.
