Race and racism

How is it possible to account for the revival of an ideology and a doctrine whose scientific bases have been widely refuted? If the ideology of race, although today deprived of all scientific verisimilitude, is re-mobilized in political discourses, across the world, it is not because it is based on universal categories, but for it results from a violent history; that of Europe's relations with the rest of the world that bear the scars of a double tragedy: colonialism and slave trade.
This revival is not limited to Europe or to the confrontation with the Muslim world. It is erupting in sub-Saharan Africa where it is based on the ethnic category invented by colonization and reinvented by the post-colonial powers... But it is also manifesting itself in other regions of the world. This issue offers case studies on every-street-corner racism, the one geographically closest to us. But it provides also research that seeks to take the notion out of its context to show how racism can be tackled by societies governed by value systems markedly different from ours.
