Epilogue

"This book is a path breaking contribution to the study of democracy. Its novel approach to understanding technical and ethical controversies shows how the uncertainties people share about the world and its future can become the source of new forms of democratic life." --Timothy Mitchell, Columbia University "This lucid and engaging book not only breathes new life into science and technology studies, but it also reinvents and re-enchants politics. It traces a new democratic politics of the unknown."--Ash Amin, Department of Geography, Durham University -- Ash Amin "In this provocative book, Michel Callon analyses the hybrid forums taking shape in the controversial sites where science overflows into the everyday world, where specialist knowledge is being challenged, new kinds of dialogic democracy are being born, and new styles of measured action are coming into being that enable human beings to reach decisions despite endemic uncertainty. Such a democratization of democracy could have implications far beyond the public understanding of science. The crucial contribution of this book is to suggest that this 'philosophy in the wild' could provide the basis for all who have to act in an uncertain world." Nikolas Rose , Martin White Professor of Sociology, and Director, BIOS Centre for the Study of Bioscience, Biomedicine, Biotechnology and Society, London School of Economics "This lucid and engaging book not only breathes new life into science and technology studies, but also reinvents and re-enchants politics. It traces a new democratic politics of the unknown." Ash Amin , Department of Geography, Durham Universit
