The criterion which we have indicated for the socialized society of the future is a material one. But is the spiritual condition of an epoch to be determined by material arrangements? Is this not a confession of faith in materialism? We are speaking of a criterion, not of a prime moving force. I have no desire, however, to avoid going into the material, or rather we should say mechanical, interpretation of history. I have done it more than once in my larger works, and for the sake of coherence I may repeat it in outline here. The laws which determine individual destinies are reproduced in the history of collective movements. A man's career is not prescribed by his bodily form, his expression, or his environment; but there is in these things a certain connexion and parallelism, for the same laws which determine the course of his intellectual and spiritual life reflect themselves in bodily and practical shape. Every instant of our experience, all circumstances in which we find ourselves, every limb that we grow, every accident that happens to us, is an expression or product of our character. We are indeed subject to human limitations; we are not at liberty to live under water or in another planet; but within these wide boundaries each of us can shape his own life. To observe a man, his work, his fate, his body and expression, his connexions and his marriage, his belongings and his associations, is to know the man. From this point of view all social, economic and political schemes become futile, for if man is so sovereign a being there is no need to look after him. But these schemes re-acquire a relative importance when we consider the average level of man's will-power, as we meet it in human experience--a power which, as a rule, shows itself unable to make head against a certain maximum of pressure from external circumstances. And again, these schemes are really a part of the expression of human will, for through them collective humanity battles with its surroundings, its contemporary world, and freely shapes its own destinies.
