"If the doors of perception were cleansed everything would appear to man as it is: Infinite. This I shall do by printing in the infernal method by corrosives, which in Hell are salutary and medicinal, melting apparent surfaces away, and displaying the infinite which was hid."
William Blake, The Marriage of Heaven and Hell
