The chapters constituting this book were written under the title THE PSYCHOLOGY OF SOCIAL DEVELOPMENT from month to month in the philosophical monthly, ARYA, from August 15, 1916 to July 15, 1918 and used recent and contemporary events as well as illustrations from the history of the past in explanation of the theory of social evolution put forward in these pages. The reader has therefore to go back in his mind to the events of that period in order to follow the line of thought and the atmosphere in which it developed. At one time there suggested itself the necessity of bringing this part up to date, especially by some reference to later developments in Nazi Germany and the development of a totalitarian Communist regime in Russia. But afterwards it was felt that there was sufficient prevision and allusion to these events and more elaborate description or criticism of them was not essential; there was already without them an adequate working out and elucidation of this theory of the social cycle.
