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:
Epistemocracy
However the term had already been used long before this, and Taleb's usage has not caught on. Most uses of the word are unrelated or even opposite to this. For instance in reference to communism: "Maoism, like the Marxist- Leninist system upon which it modeled itself, was an `epistemocracy,' rule by those possessed of that infallible wisdom embodied in the `universal truth of Marxism'" Or theocracy: "The model for this concentration of knowledge in the hands of a single group is the epistemocracy of the Old Testament priests..."
