I am come of a race noted for vigour of fancy and ardour 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 cognisant of many things which escape those who dream only by night. In their grey visions they obtain glimpses of eternity, and thrill, in awakening, to find that they have been on 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.
