In this path-breaking book, Tong Lam examines the emergence of the ?culture of fact? in modern China, showing how elites and intellectuals sought to transform the dynastic empire into a nation-state, thereby ensuring its survival. Lam argues that an epistemological break away from traditional modes of understanding the observable world began around the turn of the twentieth century. Tracing the Neo-Confucian school of evidentiary research and the modern departure from it, Lam shows how, through the rise of the social survey, ?the fact? became a basic conceptual medium and source of truth. In focusing on China’s social survey movement, A Passion for Facts analyzes how information generated by a range of research practices?census, sociological investigation, and ethnography?was mobilized by competing political factions to imagine, manage, and remake the nation.
