"Dreamscapes of Modernity" is a groundbreaking non-fiction book that explores the concept of sociotechnical imaginaries, developed by Sheila Jasanoff and Sang-Hyun Kim. It provides a comprehensive analysis of how notions of scientific and technological progress are intertwined with implicit ideas about public purposes, collective visions for the future, and the common good. Through a variety of case studies, including topics such as nuclear energy in Austria, biotechnology in China, and U.S. bioethics, it demonstrates how these imaginaries can lead to a deeper understanding of the national and transnational politics of science and technology. A theoretical introduction lays the groundwork for the diverse analyses presented by the contributors, while a concluding synthesis summarizes the shared insights. This book represents a significant theoretical advancement and is considered central to research in science and technology studies.
