PREFACE TO THE SECOND EDITION
Reading edition
A few errors in the text of the First Edition have been corrected, and a sentence which had caused misunderstanding has been omitted. No other change has been made. A Postscript has been added in order to point out some of the directions in which the psychological inquiry made during the war gave a practical foresight that was confirmed by the course of events, and in order to examine the remarkable situation in which society now finds itself.
In the Preface to the First Edition I ventured to suggest that some effective knowledge of the mind might be of value to a nation at war; I take this opportunity of suggesting that such knowledge might be not less useful to a tired nation seeking peace. At the same time it should perhaps be added that this book is concerned wholly with the examination of principles, is professedly speculative in methods and conclusions, and is quite without pretensions to advise upon the conduct of affairs. August, 1919.
