"Episteme" is a philosophical term derived from the Ancient Greek word ἐπιστήμη "epistēmē", which can refer to knowledge, science or understanding, and which comes from the verb , meaning "to know, to understand, or to be acquainted with".
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.
