". . . A palimpsest, then, is a membrane or roll cleansed of its manuscript by reiterated successions. [. . .] What else than a natural and mighty palimpsest is the human brain? Such a palimpsest is my brain; such a palimpsest, oh reader! is yours. Everlasting layers of ideas, images, feelings, have fallen upon your brain softly as light. Each succession has seemed to bury all that went before. And yet, in reality, not one has been extinguished. And if, in the vellum palimpsest, lying amongst the other diplomata of human archives or libraries, there is any fantasticor which moves to laughter, as oftentimes there is in the grostesque collisions of those successive themes, having no natural connection, which by pure accident have consecutively occupied the roll, yet, in our own heaven-created palimpsest, the deep memorial palimpsest of the brain, there are not and cannot be such incoherencies. The fleeting accidents of a man’s life, and tis external shows, may indeed be irrelate and incongruous; but the organising principles which fuse into harmony, and gather about fixed predetermined centres, whatever heterogeneous elements life may have accumulated from without, will not permit the grandeur of human unity greatly to be violated, or its ultimate repose to be troubles, in the retrospect from dying moments, or from other great convulsions.[ . . .]
