The contributions in this ebook implement diverse research strategies that (a) uncover biopolitical and necropolitical social practices, and/or (b) question and transform those same practices in our research methods. They develop theoretical and methodological articulations questioning the hegemonic representations that classify, rank and use groups of people to produce subaltern or abject positions. Each article develops and combines a number of different strategies in the analysis of biopolitical and necropolitical practices, as if they were pieces of glass, producing unique multiple refractions of the topic being researched. In different ways, the papers address three central practices in bio/necropolitics: the delimitation of physical and/or subjective territories; the valued stratification of such territories; and the development of a political economy of life and associated epistemologies where one's survival depends on the Other's death.
