Prozorov reconstructs an ontology of freedom in Foucault's textual corpus AND outlines the modalities of its practice in the contemporary terrain of global governance on the basis of a new interpretation of the relation of Foucault's approach to the problematic of sovereignty. Critically engaging with acclaimed post-Foucauldian theories of Giorgio Agamben and Antonio Negri, this book restores the controversial notion of the sovereign subject to the critical discourse on global politics. As a study in political thought, this book will be suitable for students and scholars interested in the problematic of political freedom, philosophy and global governmentality.
