I have been working on this book for a rather long time, and I’m grateful to many people for their generous help. Thanks go in particular to Ed Miliband, Patrick Legalès, Olivier Borraz, Chris Howell, Alan Finlayson, Magnus Ryner, Geoff Eley, Peter Hall, Andrew Martin, Jonas Pontusson, Andrew Scott, Mary Hilson, Victor Perez Diaz, Bo Rothstein, and Joakim Palme. I would also like to thank the Swedish Institute for Futures Studies and my colleagues for their interest in this book. As I write the last words, my thoughts go to two wonderful people in a beautiful house in Somerville, Massachusetts, who gave me a home during my stay at Harvard: Ann Gallagher and Frank Roselli.
