These weeks I’ve turned from biographical and summary readings to Foucault’s early works. From here on, these posts will proceed at conceptual levels as much as is possible. Today, we turn to archaeology. In its simplest reduction, the concept denotes a history of discourse. In books such as the History of Madness, the Archaeology of Knowledge, and the Order of Things, Foucault undertakes examinations of discursive formations ranging from health and madness to scientific understanding to aesthetics and perception. Throughout each of these, he frames the conditions of knowledge in a given time period as constrained by the characteristics of that period, a general way of organizing and thinking about the world in each that he names an episteme. So, archaeology is the study of “epistemae,” and an episteme places discourse in historical context.
