You see, I have never felt the need to invent a world beyond this world, for this world has always seemed large and beautiful enough for me. I have wondered why it is not large and beautiful enough for others-- why they must dream up new and marvelous spheres, or long to live elsewhere, beyond this dominion... but that is not my business. We are all different, I suppose. All I ever wanted was to know this world. I can say now, as I reach my end, that I know quite a bit more of it than I knew when I arrived. Moreover, my little bit of knowledge has been added to all the other accumulated knowledge of history-- added to the great library, as it were. That is no small feat, sir. Anyone who can say such a thing has lived a fortunate life.
