From Lord of the Rings: The Two Towers:
[Samwise Gamgee to Frodo Baggins]
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 ot know the end. Because could the end be happy? How could the world go back to the way it was when so much 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 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. Because they were holding on to something.
What were they holding on to, Sam?
There’s some good in this world, Mr. Frodo. And it’s worth fighting for.
