In this paper we sought to study, through a detailed review of Dora's analytic material, the specific nature of her oedipal conflict and its expression in her treatment with Freud as manifested in her dreams, associations, and transference. We found that while Freud was surely correct in considering Dora's positive oedipal conflict as an important source of her psychopathology, the implication of her early regression to a phallic-oedipal position was not fully appreciated or interpreted, leading to her eventual premature termination. While Freud analyzed, largely following the end of the treatment, Dora's erotic love for Frau K., he did not see this love as deriving from an integrated phallic-oedipal complex which included competitive and castrative strivings toward men as well as wishes to love a woman from a phallic position. Thus we sought to extend Freud's analysis of the case by delineating the specific form of Dora's homosexual love, the genetic sources for it, and the aggressive wish toward men as they derive from a particular substage of the oedipal phase for females, the phallic-oedipal phase. We conclude that Dora's hostility toward Freud, her father and Herr. K. resulted not only from injured pride but, more basically, from her jealousy and rivalry with father for mother's love. In her treatment Dora's phallic-oedipal wishes became increasingly dominant. They were manifested in the transference with her first acting to engage Freud's interest and then thwarting his interpretive efforts, ultimately by leaving the treatment altogether. The case well illustrates the importance of understanding the role of the phallic-oedipal phase in female hysterical patients.
