Better

I am wise enough to know that there are some perils from which a man must flee.

If this is victory, then our hands are too small to hold it.

In this Music [the singing of the angels in harmony] the World was begun; for Iluvatar made visible the song of the Ainur,and they beheld it as a light in the darkness.

It is not our part to master all the tides of the world, but to do what is in us for the succor 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. What weather they shall have is not ours to rule.

It is not possible even at great length to pot The Lord of the Rings in a paragraph or two ? It was begun in 1937, and every part has been written many times. Hardly a word in its 600,000 or more has been unconsidered. And the placing, size, style, and contribution to the whole of the features, incidents, and chapters has been laboriously pondered. I do not say this in recommendation. It is, I feel, only too likely that I am deluded, lost in a web of vain imaginings of not much value to others ? in spite of the fact that a few readers have found it good, on the whole. What I intend to say is this: I cannot substantially alter the thing. I have finished it, is off my mind: the labor has been colossal: and it must stand or fall, practically as it is.
