The notion of the ‘Other gender’ describes women’s status in patriarchal societies, as explored in Simone de Beauvoir’s The Second Sex. Women are defined and differentiated in relation to men, constituting norms; they are inessential (the Other), in opposition to the essential (a Man as the Subject, the Absolute, the One). In this relation, there is no (balanced) reciprocity.
