Philos. [f. Gr. ἄγνοι-α ignorance + -(O)LOGY.] The doctrine of those things of which we are necessarily ignorant; that department of philosophy that inquires into the character and conditions of ignorance.
1856. Ferrier, Inst. Metaph., 51. We must examine and fix what ignorance is—what we are, and can be, ignorant of. And thus we are thrown upon an entirely new research, constituting an intermediate section of philosophy, which we term the agnoiology … the theory of true ignorance.
