This collection fills an important gap in our understanding of the role of uncertainty in the science-society nexus. It illustrates the growing awareness that, in this context, uncertainty is essentially a political concern to be addressed by better governance rather than a scientific problem to be solved by improved techniques. Scientific uncertainty will continue to be a challenge for contemporary societies as long as the legitimacy of policy decision-making and action is based on trust in science.Professor Silvio Funtowicz, Centre for the Study of the Sciences and the Humanities, University of Bergen; formerly EU Joint Research Centre, Ispra What should we do with uncertainty? Not abolish it with facts, this wide-ranging essay collection argues. Introduced by two of our most incisive analysts of alternative social futures, the book delves into today's most significant governance challenges and shows how uncertainty leads us to reimagine the politics of modernity. In these turbulent times, this is a book to read, savor and read again. Professor Sheila Jasanoff, Pforzheimer Professor of Science and Technology Studies at the Harvard Kennedy School The old world order is fading into history: what a new one will look like is currently uncertain. In fields as diverse as climate change, finance, urban futures, pandemics, mass migration and many more, the future looks less predictable and demands alternative approaches. This well-timed book lays out what they might be.
