Foucault's interest in security, race and war therefore arises out of, and remains integrally associated with, his changing analytic of modern political and power relations, the rules of truth and truths of rule which he calls politics of truth. It arises out of his concern with liberalism as a regime of power and in particular with liberal governmentality which takes species life as its referent object of power relations: that is, liberal biopolitics. From Foucault's perspective, the story of biopoliticised race arises with the birth of political modernity. Race is one of the markers which biopolitically adjudicates Life. It contributes directly to the triangulation of biopolitics with its necropolitics. Foucault maintains historically that political modernity arose from war, specifically race war. Biopolitics changes, however, according to what the complex assemblages of power or knowledge, which take species existence as their referent epistemic object, teach us about the changing conceptualisations and practices of species existence.
