Not less stimulating and informative than the first, is the second part of the present volume, containing Freud’s own story of his life and his science. It is common knowledge today that Freud, in his inimitable objectivity, has always published facts and fancies which other scientists would have been only too careful to hide from the eyes of their contemporaries. On the occasion of Freud’s seventieth birthday, I wrote in THE INTERNATIONAL JOURNAL OF PSYCHOANALYSIS (July/October 1926): So far as his personality is concerned, he has completely taken the wind from the sails of modern methods of inquiry which attempts to gain fresh insight into the development of a scientist’s views, by studying the intimate details of his private life. In his “_Traumdeutung_” and “_Psychopathologie des Alltagslebens_”, Freud has undertaken this task himself in a way previously unknown, and has not only indicated new lines of research for this kind of inquiry, but given for all time an example of a candor quite ruthless towards himself. He has also revealed unhesitatingly the ‘secrets of the laboratory’, the inevitable vacillations and uncertainties that are usually so carefully kept hidden. I hope that the reader will agree with me that the part of this book which contains Freud’s “An Autobiographical Study” again displays candor and frankness to an astonishing degree. This part of the present volume, aside from other information, will also demonstrate to the student of psychology the tolerance Freud manifests in regard to former disciples of his who, apparently driven by an overpowering impatience, or because “they did not fancy to dwell in the Depths of the Unconscious” only too early, and with deplorable rashness, hastened to generalize their ideas, notwithstanding the insufficiency of their theories to explain complicated facts. As far as I am personally concerned, I cannot help considering Freud as one of the most progressive disciples of his own teachings, while the apostates of his doctrine appear to me as prematurely aged reactionaries. Equipped with devious excuses and devices, these apostates deserted the paths of Freud’s teachings—paths that require the courage of the born pioneer—to return to the broad and beaten paths of orthodox psychology and biology. May I not once more quote myself in this connection? On December 28, 1926, speaking before the Mid-winter meeting of the American Psychoanalytical Association, I said:
