Personification of Episteme in Celsus Library in Ephesus, Turkey.

Episteme means knowledge, as in "justified true belief" in the terminology of the philosopher Plato. It is etymologically derived from the Ancient Greek word ἐπιστήμη for knowledge or science, which comes from the verb ἐπίσταμαι, "to know". Episteme as knowledge contrasts doxa, Plato's term for common belief or opinion. Episteme is distinguished from techne, which is knowledge in an applied way as in a craft. The word epistemology, means the study of knowledge, and is derived from episteme.

Michel Foucault

The French philosopher and social theorist Michel Foucault used the term épistème in a highly specialized sense in his work The Order of Things to mean the historical a priori that grounds knowledge and its discourses and thus represents the condition of their possibility within a particular epoch. In subsequent writings, he made it clear that several epistemes may co-exist and interact at the same time, being parts of various power-knowledge systems. But he did not discard the concept:

I would define the episteme retrospectively as the strategic apparatus which permits of separating out from among all the statements which are possible those that will be acceptable within, I won’t say a scientific theory, but a field of scientificity, and which it is possible to say are true or false. The episteme is the ‘apparatus’ which makes possible the separation, not of the true from the false, but of what may from what may not be characterised as scientific.[1]

Yet in Foucault's The Order of Things he describes Episteme as:

However, if in any given culture and at any given moment, there is always only one episteme that defines the conditions of possibility of all knowledge, whether expressed in a theory or silently invested in a practice. (Foucault, 168)

Foucault's use of episteme has been asserted as being similar to

"Truth is a thing of this world: it is produced only by virtue of multiple forms of constraint. And it induces regular effects of power. Each society has its regime of truth, its “general politics” of truth: that is, the types of discourse which it accepts and makes function as true; the mechanisms and instances which enable one to distinguish true and false statements, the means by which each is sanctioned; the techniques and procedures accorded value in the acquisition of truth; the status of those who are charged with saying what counts as true"[5][6]
