This edition includes a modern introduction and a list of suggested further reading. "e;Beyond the Pleasure Principle"e; marks a major turning point in the evolution of Sigmund Freud's psychoanalytic thought. It is at once richly complex, daringly conceptual, and highly controversial. It leads Freud to a restatement of his theory of consciousness and of the "e;topography"e; of the human mind. At the same time, it provides a charming glimpse of an intimate family experience with his grandson, supporting the formulation of his new concept of the "e;compulsion to repeat"e; which became the basis for his radical revision of what he termed his "e;metapsychology"e;-the "e;scientific"e; foundation for his clinical theory.
