I AM come of a race noted for vigor of fancy and ardor of passion. Men have called me mad; but the question is not yet settled, whether madness is or is not the loftiest intelligence — whether much that is glorious- whether all that is profound — does not spring from disease of thought — from moods of mind exalted at the expense of the general intellect. They who dream by day are cognizant of many things which escape those who dream only by night. In their gray visions they obtain glimpses of eternity, and thrill, in awakening, to find that they have been upon the verge of the great secret. In snatches, they learn something of the wisdom which is of good, and more of the mere knowledge which is of evil. They penetrate, however, rudderless or compassless into the vast ocean of the “light ineffable,” and again, like the adventures of the Nubian geographer, “agressi sunt mare tenebrarum, quid in eo esset exploraturi.”
We will say, then, that I am mad. I grant, at least, that there are two distinct conditions of my mental existence — the condition of a lucid reason, not to be disputed, and belonging to the memory of events forming the first epoch of my life — and a condition of shadow and doubt, appertaining to the present, and to the recollection of what constitutes the second great era of my being. Therefore, what I shall tell of the earlier period, believe; and to what I may relate of the later time, give only such credit as may seem due, or doubt it altogether, or, if doubt it ye cannot, then play unto its riddle the Oedipus.
-Eleonora, Edgar Allan Poe
