"It is not our part to master all the tides of the world, but to do what is in us for the succour of those years wherein we are set, uprooting the evil in the fields that we know, so that those who live after may have clean earth to till."
- J.R.R. Tolkien, “The Lord of the Rings”
Sam: "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'll 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 the world, Mr. Frodo, and it's worth fighting for."
