The past is all of one texture–whether feigned or suffered–whether acted out in three dimensions, or only witnessed in that small theatre of the brain which we keep brightly lighted all night long, after the jets are down, and darkness and sleep reign undisturbed in the remainder of the body. There is no distinction on the face of our experiences; one is vivid indeed, and one dull, and one pleasant, and another agonising to remember; but which of them is what we call true, and which a dream, there is not one hair to prove. The past stands on a precarious footing; another straw split in the field of metaphysic, and behold us robbed of it. There is scarce a family that can count four generations but lays a claim to some dormant title or some castle and estate: a claim not prosecutable in any court of law, but flattering to the fancy and a great alleviation of idle hours. A man's claim to his own past is yet less valid. A paper might turn up (in proper story-book fashion) in the secret drawer of an old ebony secretary, and restore your family to its ancient honours, and reinstate mine in a certain West Indian islet (not far from St. Kitt's, as beloved tradition hummed in my young ears) which was once ours, and is now unjustly some one else's, and for that matter (in the state of the sugar trade) is not worth anything to anybody.
