In this post we look at Simon Schaffer’s “The Show That Never Ends: Perpetual Motion in the Early Eighteenth Century,” British Journal for the History of Science 28 (1995): 157-189, in which he sets himself the task of explaining the intellectual and political viability of perpetual motion schemes, particularly in “the lands dominated by the Hapsburgs, the Empire and northern Italy” (162). This is a difficult challenge, since, as Schaffer points out, such machines had been subjected to widespread doubt and criticism from the middle of the seventeenth century. Yet, they did have a place, and what Schaffer, I think, accomplishes here is that he makes that place fit more coherently into what we know about how, in general, engineering and philosophical novelties were handled in the early 18th-century milieu.
