The Essentials of Psycho-Analysis book by Sigmund Freud

Distilled into one volume by his daughter Anna, this volume of Freud's writings constitutes a key to the understanding of his work. It includes "The Question of Lay Analysis", "Three Essays on the Theory of Sexuality", "On Dreams", "The Ego and the Id", "Beyond the Pleasure Principle" and 15 shorter pieces. Together, they provide a comprehensive picture of all the central Freudian concepts, and how they connect up to make one of the most challenging bodies of thought of the 20th century.
