The 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). The contemporary study of the History of Ideas concerns the transitions between historical world-views, but ultimately depends upon narrative continuities that break down under close inspection. The history of ideas marks points of discontinuity between broadly defined modes of knowledge, but those existing modes of knowledge are not discrete structures among the complex relations of historical discourse. Discourses emerge and transform according to a complex set of relationships (discursive and institutional) defined by discontinuities and unified themes. An énoncé (statement) is a discourse, a way of speaking; the methodology studies only the “things said” as emergences and transformations, without speculation about the collective meaning of the statements of the things said. A statement is the set of rules that makes an expression — a phrase, a proposition, an act of speech — into meaningful discourse, and is conceptually different from signification; thus, the expression “The gold mountain is in California” is discursively meaningless if it is unrelated to the geographic reality of California. Therefore, the function of existence is necessary for an énoncé (statement) to have a discursive meaning.
