Epistemology
The word "epistemology" is derived from the ancient Greek "epistēmē" meaning "knowledge" and the suffix "-logy", meaning "logical discourse" (derived from the Greek word "logos" meaning "discourse"). It is analogue to the German "Wissenschaftslehre" (literally, theory of science) which was introduced by philosophers Johann Fichte and Bernard Bolzano in the late 18th century. The word first appeared in English in 1847 as a translation of the German in New York's "Eclectic Magazine" review of a philosophical novel by German author Jean Paul:
Epistemic community
From this view, an epistemic community may be seen as a group of people who do not have any specific history together, but search for a common idea of home as if forming an intentional community. For example, an epistemic community can be found in a network of professionals from a wide variety of disciplines and backgrounds.
