ABSTRACT
In old days there were many civilisations and many nations still untouched by civilisation. Now, the world is becoming a unity, dominated by the industrial system which, beginning in the north of England about 150 years ago, has already spread to all the great nations and acquired control of all the main economic resources. If it decays, it cannot be regenerated from without; if it destroys itself in internecine wars, there will be no fresh races to build upon the ruins. This is a new fact of our age, which makes inferences from past history somewhat precarious.
