The author illustrates with a clinical case the correctness of the psychoanalytic principle of continuing the analytic process, specifically the fundamental rule, to the very end of analysis. Toward the end of the last hour a patient, who had said many times that he could not remember having had incestuous fantasies, recalled that on reading Ibsen's Ghosts during his adolescence he had thought Oswald could do nothing but have intercourse with his mother. He then recalled that he used to think: 'Wouldn't it be nice to have someone in the house to have intercourse with?'.
