Wilhelm Stekel was an Austrian physician and psychologist and one of Freud's earliest followers. This title, originally published in 1921, was the author's favourite of his own work. In the preface he says: 'It was written in the beautiful years in which the first rays of analytic psychognosis penetrated the darkness of the human soul.' Covering a variety of topics he takes a psychoanalytic look into The Depths of the Soul .
