This chapter explains the main conceptions of sexual difference that have influenced feminist theory, tracing their roots in the psychoanalysis of Freud and Lacan, and then introducing the radical rethinking of sexual difference put forward by Luce Irigaray. For Irigaray, in the Western symbolic order there has only ever been sexual hierarchy, not genuine sexual difference. Her political program for changing the symbolic order to create a positive feminine subject-position—one that is not merely the underside or negative opposite of the masculine position—has been developed practically by some Italian feminists. A family of related concepts of sexual difference has become part of feminist theory, stemming from two main sources: the psychoanalytic theories of Freud and Lacan and the work of the Belgian-born philosopher Luce Irigaray, herself a practicing psychoanalyst.
