Science entails history writing: scientists are continuously engaged in creating “imagined pasts” for their own specialisms, both on the small scale of the ubiquitous literature review and on a much broader scale. This aspect of science has been considered in very different ways in decades-old, yet largely neglected, contributions by Thomas S. Kuhn, Augustine Brannigan, and Simon Schaffer. Inspired by these pieces and by the missing dialogue between them, this essay argues that their concealment is itself an instance, on the (...) broadest possible scale, of the power of “imagined pasts”—in this case the imagined continuity, inscribed in the very name of our discipline, between Isaac Newton and ourselves.
