Rosine Jozef Perelberg articulates a Freudian metapsychology with modern preoccupations with questions of sexual difference and differences. She expands on the ideas presented in her previous book edited work, . The author’s approach brings back into focus Freud‘s idea that "one is not born already made as a man or woman, but one is constituted as such in the process of development". Freud’s theoretical writing on bisexuality is examined, returning us firmly to infantile sexuality and the Oedipus complex and the "repudiation of femininity". Perelberg draws on her past training as a social anthropologist to propose and explore the differentiation between sex, gender, and sexuality. She considers post-war academic work in gender and women’s studies and queer theory, arguing that the object of psychoanalysis is not gender but sexuality, which establishes a link between the sexual and the unconscious. She suggests that the unconscious permanently challenges our apparent unity as subjects. Sexuality, Excess and Representation will be of great interest to all practicing psychoanalysts and psychoanalytic psychotherapists.
