This volume contains all of Freud's major writings on sexuality. It begins with his revolutionary "Three Essays on the Theory of Sexuality" (1905). It also includes shorter papers on normal and abnormal sexuality, illustrated by numerous examples provided by Freud's own patients. These writings follow the full range and development of this thought up to 1931, covering such topics as sexual education of children, the psychology of love, perversions, the taboo of virginity and anal eroticism. His views changed considerably over the years, particularly those concerning the development of sexuality in children, the Oedipus complex, the relation of character to sexual types and the sexual life of women.
