Seeing Foucault’s theory through African lenses: The discourse on sex, gender and power
The paradigm of male domination exemplified by the social relations between the sexes is structured in a way that men dominate and women submit. As such, these socio cultural relations presuppose a dyadic conception of domination in which women are subject to men. If men are domineering and women are docile, then it is contradictory to say women have power. However, in line with Foucault’s idea on...
