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
The term epistemocracy has many conflicting uses, generally designating someone of rank having some epistemic property or other. Nassim Nicholas Taleb used it in 2007 to designate a utopian type of society where the leadership possesses epistemic humility. He claims the French writer Michel de Montaigne was a modern epistemocrat. He points out, however, that it is difficult to assert authority on the basis of one's uncertainty; leaders who are assertive, even if they are incorrect, still gather people together.
