In this chapter, the author presents her own efforts apparent in her careful examination of patients' material and in her perceptive observations. It discusses characteristic of S. Freud's: he had told her that it is necessary to get ideas that one is dealing with in one's mind 'out'—to make something of them outside of oneself, to give ideas existence independent of oneself. Important as is the author contribution to psychoanalysis as translator of Freud's works, it is in her relationship to Melanie Klein that she is best known. Insight that she gained from her understanding of Klein's work helped her to make her own important contributions to psychoanalysis. The chapter identifies femininity as the mask that some women put on to hide their phallic rivalry and hatred of men, offering themselves as castrated beings to particular types of men, such as potential father figures, to placate them.
