If any work in the twentieth century can be said to have revolutionized the patterns of modern thought and scientific inquiry, it is THE INTERPRETATION OF DREAMS. Freud himself said: "It contains the most valuable of all the discoveries it has been my good fortune to make." This translation by James Strachey is the definitive one incorporating all the alterations, additions, and deletions Freud made over a thirty-year period. The detailed commentary and scrupulous cross referencing enable the reader to understand clearly the development of Freud's thought. The publication of THE INTERPRETATION OF DREAMS marked the real beginning of psychoanalysis and of the pervasive psychoanalytic view of man and society.
