Abstract

DeLacy reviews European developments in biology and microscopy and the reception of these ideas by members of the Royal Society during the years when the Society was publishing the letters of Antoni van Leeuwenhoek. Fellows of the Society, including John Ray, Tancred Robinson, Martin Lister, and Edward Tyson, questioned whether any living entity could be spontaneously generated, forcing a reconsideration of ideas about the nature and origins of contagium vivum, or living contagion. Interest in the possible role of small “worms,” “animalcules,” or “insects” in spreading epidemics coincided with an international epizootic of cattle plague or rinderpest, which inspired a widespread discussion of the mechanism of contagion and the imposition of quarantines to contain the outbreak.

Borgondio (1679–1741), a friend of Vallisneri, was a teacher and mentor of the Croatian physicist and mathematician Roger Joseph Boscovich, SJ and FRS, whose atomic theories inspired the monist matter theory of Joseph Priestley.

  55. Ray originally thought that a material “specific essence” was being transmitted within species. Stephen Gaukroger, The Collapse of Mechanism and the Rise of Sensibility: Science and the Shaping of Modernity, 1660–1760 (Oxford: 2010), 193, following Phillip Sloan, argues that Ray abandoned the concept of “species essentialism” by the 1690s under Locke’s influence. This, however, is a claim about Ray’s epistemology—he agreed with Locke that we cannot know about essences—not about his theory of generation. Ray conceded that all humanmade classifications are artificial because they cannot capture essences, but presumably a perfect “natural” classification would avoid this problem. See Sloan, “John Locke, John Ray, and the Problem of the Natural System,” Journal of the History of Biology (1972) 5, no. 1:1–53, on 46, esp. n. 121.
