Many colleagues and friends have provided invaluable assistance and constructive criticism at various stages of this project. From the University of Sydney, I thank Charlotte Epstein, Duncan Ivison, Jane Park, John Keane, Kiri Flutter, Joy Twemlow, Megan Quinn, Marco Duranti, Moira Gatens, and Simon Tormey. I am also indebted to what I hope will one day be known as the unsw Foucault school: Ben Golder, Paul Patton, and Miguel Vatter. Keith Ansell-Pearson, Jane Bennett, Leonard Lawlor, Ella Myers, and Felisa Tibbitts provided advice and encouragement at crucial points. Courtney Berger was her usual wonderful editorial self, and I am lucky to have her patient and excellent direction. I am especially grateful for three wonderful colleagues, Danielle Celermajer, Samuel Moyn, and an anonymous reviewer for Duke University Press, all of whom helped me more than I could have hoped for, and for my wife, Melanie White, and her tender loving care. This book is dedicated to Melanie, to our beautiful daughter Beatrice, and to my parents Georges and Joanne.
