"Mitchell Dean has written an outstandingly clear and scholarly introduction to the central theses and methods of the analysis of the mentalities and techniques of rule… He not only provides a guide to Foucault′s own thought in this area, but he also draws upon other key thinkers in contemporary social theory to develop original and illuminating analysis of some principle formations of political power. Dean′s book should become required reading not just for those interested in the work of Michel Foucault, but for all those who are concerned with the dilemmas of contemporary politics." - Nikolas Rose, Goldsmiths, Praise for the First Edition Originally published in 1999 this exceptionally clear and lucid book quickly became the standard overview of what are now called ′governmentality studies′. With its emphasis on the relationship between governmentality and other key concepts drawn from Michel Foucault, such as bio-politics and sovereignty, the first edition anticipated and defined the terms of contemporary debate and analysis. In this timely second edition Mitchell Dean engages with the full textual basis of Foucault′s lectures and once again provides invaluable insights into the traditions, methods and theories of political power identifying the authoritarian as well as liberal sides of governmentality. Every chapter has been fully revised and updated to incorporate, and respond to, new theoretical, social and political developments in the field; a new introduction surveying the state of governmentality today has also been added as well as a completely new chapter on international governmentality.
