 The Notion of Sexage and Contemporary Feminist Debates 
One of Colette Guillaumin’s major theoretical contributions was the notion of sexage. I propose to analyze it from three angles : upstream, taking into account her previous work on racism ; in itself, what it consists of and what it allows us to think ; downstream, regarding its usefulness as it relates to the contemporary issues facing feminisms. Upstream, I propose articulating the notion of sexage with analyses of racism, more particularly focusing on the consequences of the processes of naturalization of social groups from the point of view of othering (idea of difference) and hierarchization. The sexage relationship seeks to describe the social relationship established between the sexes and is based on the collective appropriation of women as well as their individual appropriation, thus a double appropriation that operates within the apparatus of heterosexuality. But the double individual and collective dimension of sexage implies the marking of bodies, the concrete mechanisms of which fluctuate with the rhythm of social struggles. Guillaumin’s work is essentially based on the homology between sexism and racism. Can this homology be countered with the sarcastic remark that “all the women are white and all the blacks are men” ? Not necessarily. It seems to me that the materialist analysis of social relations, flowing from her work, works well with contemporary theories of social localization, theories that do not reason in terms of identity or difference, but rather insist on the agency of social subjects to transform the web of social relations within which they are embedded.
