On Metapsychology - The Theory of Psychoanalysis: "Beyond the Pleasure Principle", "Ego and the Id" and Other Works (Penguin Freud library)

Covering the last three decades of Freud's life, this collection provides a chronological account of Freudian metapsychology, enabling the reader to trace the development of Freud's thought and modification of his theories in the light of his findings from his clinical work. These writings cover all the topics central to psychoanalytical theory: the role of the unconscious in mental life, instinct theory (including the life and death instincts and the concepts of repetition compulsion), reality-testing and the ego's relation to the external world.
