Foucault specifies these conditions more precisely in the Archeology, where he redefines the épistemè as "the total set of relations that unite, at a given period, the discursive practices that give rise to epistemological figures, sciences, and possibly formalized systems."But in “The Order of Things” Foucault explains this project in the rather Kantian language of "conditions of possibility," which he attempts to historicize through the concept of the épistemè.
