This book presents a novel conception of political freedom developed on the basis of the work of Foucault. Against the prevailing interpretations which disqualify a Foucauldian approach from the discourse of freedom, this study posits freedom as the primary axiological motif of Foucault's writing. 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.
