The Human Cycle, The Ideal of Human Unity, War and Self-Determination

The Human Cycle was first published in monthly instalments in the review Arya between August 1916 and July 1918 under the title The Psychology of Social Development. Each chapter was written immediately before its publication. The text was revised during the late 1930s and again, more lightly, in 1949. That year it was published as a book under the title The Human Cycle. The Publisher's Note to the first edition, which was dictated by Sri Aurobindo, is reproduced in the present edition.
The Ideal of Human Unity was written and published in monthly instalments in the Arya between September 1915 and July 1918. In 1919 it was brought out as a book. Sri Aurobindo wrote a Preface to that edition which is reproduced in the present volume. He revised the book during the late 1930s, before the outbreak of World War II. References to political developments of the period between the world wars were introduced at this time, often in footnotes. In 1949 Sri Aurobindo undertook a final revision of The Ideal of Human Unity. He commented on the changed international situation in footnotes and made alterations here and there throughout the book, but brought it up to date mainly by the addition of a Postscript Chapter. In 1950 the revised text was published in an Indian and an American edition.
Five of the essays making up War and Self-Determination were published in the Arya between 1916 and 1920. In 1920 three of them — "The Passing of War?", "The Unseen Power" and "Self-Determination" — along with a Foreword and a newly written essay, "The League of Nations", were published as a book. In later editions the other two Arya essays, "1919" and "After the War", were added by the editors.
