The "Human Subject," "Vulnerable Populations," and Medical History: The Problem of Presentism and the Discourse of Bioethics.

This discussion considers recent historical works of eugenics and sterilization in Canada, but it is not an historiographic review essay or critique per se of this literature. Rather, by focussing on the topic of historic diagnostic categories such as "feeble-minded," "idiot," and "moron," methodological issues such as historical presentism and its possible interactions with the discourse of modern bioethics are examined. The conclusions derived are meant only to be cautionary, and are neither prescriptive nor proscriptive. Medical historians undertaking analyses of currently contentious topics that may directly involve or indirectly allude to "human subjects" or "vulnerable populations" perhaps ought to reflect on the degree, if any, they may be anachronistically writing contemporary bioethical categories into bygone eras.
