Enjoying the grand sweep of Tolkien’s vision as I read aloud to my kids:
“And doubtless the good stone-work is the older and was wrought in the first building,” said Gimli. “It is ever so with the things that Men begin: there is a frost in Spring, or a blight in Summer, and they fail of their promise.”
“Yet seldom do they fail of their seed,” said Legolas. “and that will lie in the dust and rot to spring up again in times and places unlooked-for. The deeds of Men will outlast us, Gimli.”
“And yet come to naught in the end but might-have-beens, I guess,” said the Dwarf.
“To that the Elves know not the answer,” said Legolas.
[Legolas speaking, later in the chapter:] “In that hour I looked on Aragorn and thought how great and terrible a Lord he might have become in the strength of his will, had he taken the Ring to himself. Not for naught does Mordor fear him. But nobler is his spirit than the understanding of Sauron; for is he not of the children of Lúthien? Never shall that line fail, thought the years may lengthen beyond count.”
[Gandalf speaking, later in the chapter:] “We must walk open-eyed into that trap, with courage, but small hope for ourselves. For, my lords, it may well prove that we ourselves shall perish utterly in a black battle far from the living lands; so that even if Barad-dûr be thrown down, we shall not live to see a new age. But this, I deem, is our duty. And better so than to perish nonetheless–as we surely shall, if we sit here–and know as we die that no new age shall be.”
A few unconnected quotes from chapter 9 of book V in The Return of the King by J.R.R. Tolkien.
