This work seeks to show that science is rooted not just in conversation but in disagreement, doubt and uncertainty. Mara Beller argues that it is precisely this culture of dialogue and controversy within the scientific community that fuels creativity. Beller draws her argument from her reading of the history of the quantum revolution, especially the development of the Copenhagen interpretation. One of several competing approaches, this version succeeded largely due to the rhetorical skills of Niels Bohr and his colleagues. Using archival research, Beller shows how Bohr and others marketed their views, misrepresenting and dismissing their opponents as "unreasonable" and championing their own not always coherent or well-supported position as "inevitable".
