Contemporary interpretations
Michel Foucault
For
Michel Foucault, an épistémè is the guiding unconsciousness of subjectivity within a given epoch – subjective parameters which form an historical
a priori.
He uses the term
épistémè () in his
The Order of Things, in a specialized sense to mean the historical, non-temporal,
a priori knowledge that grounds truth and
, thus representing the condition of their possibility within a particular
epoch. In the book, Foucault describes épistémè:
In any given culture and at any given moment, there is always only one épistémè that defines the conditions of possibility of all knowledge, whether expressed in a theory or silently invested in a practice.
In subsequent writings, he makes it clear that several épistémè may co-exist and interact at the same time, being parts of various power-knowledge systems. Foucault attempts to demonstrate the constitutive limits of discourse, and in particular, the rules enabling their productivity; however, Foucault maintains that, though ideology may infiltrate and form science, it need not do so: it must be demonstrated how ideology actually forms the science in question; contradictions and lack of objectivity are not an indicator of ideology. Jean Piaget has compared Foucault's use of épistémè with Thomas Kuhn's notion of a paradigm.[.]
