Time turns our lies into truths.

~ Gene Wolfe

Hope is a psychological mechanism unaffected by external realities.

And what of the dead? I own that I thought of myself, at times, almost as dead. Are they not locked below ground in chambers smaller than mine was, in their millions of millions? There is no category of human activity in which the dead do not outnumber the living many times over. Most beautiful children are dead. Most soldiers, most cowards. The fairest women and the most learned men – all are dead. Their bodies repose in caskets, in sarcophagi, beneath arches of rude stone, everywhere under the earth. Their spirits haunt our minds, ears pressed to the bones of our foreheads. Who can say how intently they listen as we speak, or for what word?

~ Gene Wolfe

There is one final point, the point that separates a true multivolume work from a short story, a novel, or a series. The ending of the final volume should leave the reader with the feeling that he has gone through the defining circumstances of Main Character's life. The leading character in a series can wander off into another book and a new adventure better even than this one. Main Character cannot, at the end of your multivolume work. (Or at least, it should seem so.) His life may continue, and in most cases it will. He may or may not live happily ever after. But the problems he will face in the future will not be as important to him or to us, nor the summers as golden.
