Textual Observatio(n): The Language Scholar as Empiricist

Historians of science have delivered rich studies of the development and disciplined practice of observation across a wide investigative spectrum. But there is more to say about the role of scholars whose primary objects of study are textual and linguistic, who found themselves bent not over operating tables or lenses but lists of ancient words and the writings they came from. This paper examines the disciplined sight of Renaissance scholars intent on restoring Latin usage. It shows that as early as the quattrocento they were using the term observatio to describe their linguistic investigations, and doing so in a way that anticipated the more widely heralded observational efforts (and discussions) of early modern medical professionals. The implication: the embrace of disciplined sight as a credited and explicitly theorized knowledge-making tool was as pivotal for those working to unlock the secrets of grammar and usage as for those working to heal sick patients. As twenty-first century language-models remind us, technical and methodological shifts engineered to come to terms with texts have purchase on our engagement with physical objects, and not just the other way around.
