STUDIES IN THE PSYCHOLOGY OF SEX, VOLUME III Analysis of the Sexual Impulse Love and Pain The Sexual Impulse in Women by HAVELOCK ELLIS 1927 PREFACE TO SECOND EDITION. This volume has been thoroughly revised for the present edition and considerably enlarged throughout, in order to render it more accurate and more illustrative, while bringing it fairly up to date with reference to scientific investigation. Numerous histories have also been added to the Appendix. It has not been found necessary to modify the main doctrines set forth ten years ago. At the same time, however, it may be mentioned, as regards the first study in the volume, that our knowledge of the physiological mechanism of the sexual instinct has been revolutionized during recent years. This is due to the investigations that have been made, and the deductions that have been built up, concerning the part played by hormones, or internal secretions of the ductless glands, in the physical production of the sexual instinct and the secondary sexual characters. The conception of the psychology of the sexual impulse here set forth, while correlated to terms of a physical process of tumescence and detumescence, may be said to be independent of the ultimate physiological origins of that process. But we cannot fail to realize the bearing of physiological chemistry in this field; and the doctrine of internal secretions, since it may throw light on many complex problems presented by the sexual instinct, is full of interest for us. HAVELOCK ELLIS. June, 1913. PREFACE TO FIRST EDITION. The present volume of _Studies_ deals with some of the most essential problems of sexual psychology. The _Analysis of the Sexual Impulse_ is fundamental. Unless we comprehend the exact process which is being worked out beneath the shifting and multifold phenomena presented to us we can never hope to grasp in their true relations any of the normal or abnormal manifestations of this instinct. I do not claim that the conception of the process here stated is novel or original. Indeed, even since I began to work it out some years ago, various investigators in these fields, especially in Germany, have deprived it of any novelty it might otherwise have possessed, while at the same time aiding me in reaching a more precise statement. This is to me a cause of satisfaction. On so fundamental a matter I should have been sorry to find myself tending to a peculiar and individual standpoint. It is a source of gratification to me that the positions I have reached are those toward which current intelligent and scientific opinions are tending. Any originality in my study of this problem can only lie in the bringing together of elements from somewhat diverse fields. I shall be content if it is found that I have attained a fairly balanced, general, and judicial statement of these main factors in the sexual instinct.
