Summary

The video is a recording of a lecture by Laurent Devisme, a professor in social sciences and urban studies, inaugurating a new series called ‘Passage des sciences’ at Nantes Université. The series aims to explore the role of doubt in scientific advancement and public debate. In this first session, Devisme discusses how doubt can be a driving force in urban projects, challenging the traditional view of research as purely experimental. He emphasizes the importance of citizen engagement and the need to question established knowledge in urban planning. The lecture includes interactive elements with the audience, such as colored cards for reactions, and highlights the context of growing distrust in science. Devisme argues that perplexity and doubt are essential for a renewed interest in urban fabric and for fostering critical thinking among citizens. The talk is part of a broader initiative to bridge science and society, addressing topics like urbanism, history, ethics, and environmental history over five sessions.

Critical Evaluation

The lecture provides a thoughtful and nuanced perspective on the role of doubt in urban studies, effectively challenging the stereotype of scientific research as purely experimental. Devisme’s argument is well-articulated, drawing on his expertise in urban sociology and his experience as a researcher. He successfully connects the concept of doubt to broader societal issues, such as the erosion of trust in science and the importance of citizen participation in urban planning. The interactive format, with colored cards and designated rapporteurs, encourages audience engagement and reflects the series’ goal of fostering dialogue between science and society. However, the lecture is primarily an opinion piece rather than a presentation of original research, and it lacks concrete examples or case studies to illustrate the points made. The discussion of ‘merchants of doubt’ is brief and could be expanded to provide a more thorough analysis. The title accurately reflects the content, and the lecture is well-suited for a general audience interested in urban issues and the philosophy of science. Overall, the content is valuable and thought-provoking, though it could benefit from more empirical grounding and specific references to support its claims.
