Agnoiology
(Gr. agnoio + logos, discourse on ignorance) J. F. Ferrier (1854) coined both this term and the term epistemology as connoting distinctive areas of philosophic inquiry in support of ontology. Agnoiology is the doctrine of ignorance which seeks to determine what we are necessarily ignorant of. It is a critique of agnosticism prior to the latter’s appearance. Ignorance is defined in relation to knowledge since one cannot be ignorant of anything which cannot possibly be known. — H.H.
