This antiquarian book contains the second volume of Wilhelm Stekel's ground-breaking treatise on two extremes of the human condition: sadism and masochism. This fascinating text is a clear and concise exploration of the subject that will appeal to both students and collectors alike. Within this work Stekel also makes frequent reference to the work of his contemporaries, such as Jung and Freud, which he does in an attempt to familiarise the reader with the nature of the conditions dealt with. Wilhelm Stekel (1868 - 1940) was an Austrian psychologist and physician. He was an early follower of the seminal Sigmund Freud, often described as Freud's most distinguished pupil and commonly hailed as one of the founding fathers of modern psychoanalytical methodology. Many vintage texts such as this are increasingly scarce and expensive, and it is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition. It comes complete with a specially commissioned new biography of the author.
