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 theories of truth
The ideal epistemic perspective is the set of "maximally coherent and consistent propositions". A proposition is true if and only if it is a member of this maximally coherent and consistent set of propositions (associated with several German and British 19th century idealists).
