Human stories are practically always about one thing, really, aren't they? Death. The inevitability of death. . .. . . (quoting an obituary) 'There is no such thing as a natural death. Nothing that ever happens to man is natural, since his presence calls the whole world into question. All men must die, but for every man his death is an accident, and even if he knows it he would sense to it an unjustifiable violation.' Well, you may agree with the words or not, but those are the key spring of The Lord Of The Rings
There was a deep silence, only scraped on its surfaces by the faint quiver of empty seed-plumes, and broken grass-blades trembling in small air-movements they could not feel.'Not a bird!' said Sam mournfully.'No, no birds,' said Gollum. 'Nice birds!' He licked his teeth. 'No birds here. There are snakeses, wormses, things in the pools. Lots of things, lots of nasty things. No birds,' he ended sadly. Sam looked at him with distaste.
There, peeping among the cloud-wrack above a dark tower high up in the mountains, Sam saw a white star twinkle for a while. The beauty of it smote his heart, as he looked up out of the forsaken land, and hope returned to him. For like a shaft, clear and cold, the thought pierced him that in the end the Shadow was only a small and passing thing: there was light and high beauty for ever beyond its reach.
Goodbye, master, my dear! Forgive your Sam. He'll come back to this spot when the job's done - if he manages it. And then he'll not leave you again. Rest you quiet till I come; and may no foul creature come anigh you! And if the Lady could hear me and give me one wish, I would wish to come back and find you again. Good bye!
I must indeed abide the Doom of Men whether I will or nill: the loss and the silence. But I say to you, King of the Numenoreans, not till now have I understood the tale of your people and their fall. As wicked fools I scorned them, but I pity them at last. For if this is indeed, as the Elves say, the gift of the One to Men, it is bitter to receive.
Frodo: I can't do this, Sam.Sam: I know. It's all wrong. By rights we shouldn't even be here. But we are. It's like in the great stories, Mr. Frodo. The ones that really mattered. Full of darkness and danger, they were. And sometimes you didn't want to know the end. Because how could the end be happy? How could the world go back to the way it was when so much bad had happened? But in the end, it's only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines it will shine out the clearer. Those were the stories that stayed with you. That meant something, even if you were too small to understand why. But I think, Mr. Frodo, I do understand. I know now. Folk in those stories had lots of chances of turning back, only they didn't. They kept going. Because they were holding on to something.Frodo: What are we holding onto, Sam?Sam: That there's some good in this world, Mr. Frodo... and it's worth fighting for.
