“Can crowds be anything but unwise? Is there any reason to suppose that collective judgments could be accurate? The papers gathered in this volume suggest some stimulating ways to claim that those questions could be answered affirmatively and that the so called ‘mob’ might sometimes be less foolish and less unreliable than it has commonly been taken to be. Very rewarding in times when democracy is so frequently deemed unable to cope with complex questions.” – Jean-Fabien Spitz, Professor of Political Philosophy, University of Paris I Panthéon Sorbonne
