Speaker: Joan Judge, Professor, Department of History, York University What can we learn from intellectual detritus? Focusing on cheap print, vernacular daily-use knowledge, and common readers in the Long Republic (1895-1955), this talk argues that the books an age discards as slipshod and unscientific, and the readers it disparages as superstitious and ignorant, comprise the broad epistemic terrain from which historical change is actualized. Premised on the notion that what we currently know about China’s iconic 20th-century revolutions does not explain enough, it shifts our attention from innovation to ingenuity, from “knowledge what” to “knowledge how,” from the momentous to the mundane—without losing sight of the momentous. The talk first introduces a project on “China’s Mundane Revolution” that is based on some 500, largely unstudied, daily-use texts, together with material gathered from the interstices of various archives. It then zeros in on one of the “how to” topics in the study: “how to treat a cholera infection.” Examining the ways individual common readers might have approached “the most spectacular ‘new’ disease of the nineteenth century,” the example highlights the dynamic processes of scientizing vernacular and vernacularizing scientific forms of knowledge. It also raises questions about the ways these processes align—or misalign—with the various iterations of mass politics in this critical period.
