"The best and most practical philosophers": Seamen and the authority of experience in early modern science

Within the historiography of early modern science, trust and credibility have become synonymous with genteel identity. While we should not overlook the cultural values attached to social hierarchy and how it shaped the credibility of knowledge claims, this has limitations when thinking about how contemporaries regarded the origins of that knowledge and its location in different types of workers and skillsets. Using the example of seamen in the circles of the Royal Society, this article employs the category of experience, and by extension expertise, to illustrate how recognized forms of knowledge and skill acted as routes to credibility and authority in early modern science. It argues that, within the experimental community, the seaman's authority derived from their direct experience of novel and remote phenomena and the cumulative effect of their wider experience. The accumulated experience they acquired from frequent practice, observation, and exposure translated into a form of "expertness" that rendered seamen trustworthy and credible observers and thinkers. The gentlemanly trust model does not accommodate nor acknowledge the ways the seaman's direct and accumulated experience (and that of many other professional groups) were recognized and valued in inquiry and discourse. The article therefore sets out a new model for understanding trust, credibility, and authority in early modern science that can take us beyond a restrictive mono-model that locates trust in one sociocultural category to highlight the multiple, and sometimes competing, claims to epistemological authority.
