Science, technique, technology: passages between matter and knowledge in imperial Chinese agriculture.

Many historians today prefer to speak of knowledge and practice rather than science and technology. Here I argue for the value of reinstating the terms science, techniques and technology as tools for a more precise analysis of governmentality and the workings of power. My tactic is to use these three categories and their articulations to highlight flows between matter and ideas in the production and reproduction of knowledge. In any society, agriculture offers a wonderfully rich case of how ideas, material goods and social relations interweave. In China agronomy was a science of state, the basis of legitimate rule. I compare different genres of agronomic treatise to highlight what officials, landowners and peasants respectively contributed to, and expected from, this charged natural knowledge. I ask how new forms of textual and graphic inscription for encoding agronomic knowledge facilitated its dissemination and ask how successful this knowledge proved when rematerialized and tested as concrete artefacts or techniques. I highlight forms of innovation in response to crisis, and outline the overlapping interpretative frameworks within which the material applications of Chinese agricultural science confirmed and extended its truth across space and time.
