ABSTRACT
Sigmund Freud was twenty when John and Pauline's family left Freiberg for Manchester, in England, where they settled into a comfortable life. At twenty, Freud was involved with his own projects, and the defloration phantasy, if it ever existed as such, was going to be symbolically transformed into the not unrelated curiosity prompting the investigation of infantile sexuality. The greatest shock, the most traumatic idea introduced by Freud is contained in his Three Essays on the Theory of Sexuality. Krafft-Ebing's famous book Sexual Psychopathy, published in 1886, was a great success, as were its subsequent editions. Enlarging the concept of sexuality renders a more supple quality to all frontiers rigidly established until then between so-called normal and pathological behaviour. Freud identified an ego-libido, also called narcissistic libido, distinct from an object-libido created by the investment of sexual objects. The Freudian theory of the libido, and the major role it attributes to infantile sexuality, caused great disagreement among the first disciples.
