Is France afraid of her others? By looking back at the discourses and practices that have been formed over the last fifteen years, Sarah Mazouz addresses French politics of alterity. Drawing on an ethnographic survey conducted in both public administrations in charge of combating racial discrimination and in naturalisation offices in a large city in the Paris region, she shows how immigration, nation, and racialisation are articulated in the social space. Through the analysis of these two public offices, Mazouz questions the processes of inclusion and exclusion within the national group itself and between the national and the foreigner. In so doing, she seeks to grasp the paradoxical relationship between the French Republic and her others and the plural logics producing national order.
