'The English translation of Security, Territory and Population is a major event not only for Anglophone readers of Foucault's work, but for all those concerned with understanding our present social and political condition. These lectures show that the trenchant analysis of biopower, 'power over life', which Foucault had begun in the first volume of the History of Sexuality and which he pursues here in terms of technologies of security, led him to a decisively deeper and more radical formulation of his guiding problematic what he called - the government of the self and others - the issue that would serve as the basis for all his subsequent work. Security, Territory and Population might thus properly be called the 'missing link' that reveals the underlying unity of Foucault's later thought... Burchell's translation is meticulous, supple, and attentive to the nuances of Foucault's fluid lecture style. We all stand in his debt' - Kevin Thompson, Book Review Editor, Continental Philosophy Review, Department of Philosophy, DePaul University, USA 'Foucault, and this book, has enriched and extended our understandings of the field which Foucault made his own: the history of systems of thought.' - Roger Deacon, The European Legacy
