Archaeology of knowledge

The Archaeology of Knowledge (L’archéologie du savoir, 1969) by Michel Foucault is a treatise about the methodology and historiography of the systems of thought (epistemes) and of knowledge (discursive formations) which follow rules that operate beneath the consciousness of the subject individuals, and which define a conceptual system of possibility that determines the boundaries of language and thought used in a given time and domain. The archaeology of knowledge is the analytical method that Foucault used in Madness and Civilization: A History of Insanity in the Age of Reason (1961), The Birth of the Clinic: An Archaeology of Medical Perception (1963), and The Order of Things: An Archaeology of the Human Sciences (1966).
