Author(s): Sigmund Freud
First published in 1920, Beyond the Pleasure Principle documents Freud's expansion of his psychological theories. Heretofore insisting that pleasure and sexual instinct are the chief factors in human behavior, Freud introduced the concepts of death drive and death instinct in this volume, depicting humanity as constantly struggling between the two opposing drives.
The Father of Psychoanalysis, Freud ranks among the most important figures in Western psychology, and this is his most famous work. Freud is responsible for the theories of parapraxis (Freudian slips), dreams as wish fulfillment, the Oedipus complex, repression, the unconscious mind, and other concepts.
