"a path of ascent however hard" -- Tolkien to Lewis on the mysteries and opportunities of pain (Letters² #113)

In January 1948 Tolkien said something to C. S. Lewis that hurt him. In Letter #113 Tolkien continues what appears to be a longer conversation about the incident. This is the only letter we have from the correspondence and we don't know what Tolkien said or about what he said it. I encourage the reader to go look at this letter because it makes clear that Tolkien is truly unhappy that he has wounded his friend, who is also truly unhappy, and because the words from the letter I quote below, when read out of context, don't seem particularly contrite or apologetic. 

In an article I am working on right now I quote this letter in order to show that Tolkien did not believe that the mere fact of suffering sanctified or ennobled us. I think these few sentences make that point clearly, but that's not what I am here to write about. As I was looking at this passage again yesterday I caught an allusion to Vergil's Aeneid that I probably should have caught before. I have no doubt that Tolkien intended this allusion and that Lewis would have noticed it, probably right off.

Lewis's engagement with the Aeneid was deep and lifelong, from his school days onward, so much so that he labored on and off for decades on his own translation, and Tolkien had heard him read parts of it aloud at meetings of the Inklings. A. T. Reyes provides a good discussion of this in the introduction to his book, C. S. Lewis's Lost Aeneid. Tolkien, too, was steeped in Vergil from his own school days, as was entirely normal at that time. We even have a page from the 1920s on which Tolkien transliterated phrases from the Aeneid into one of his early Elvish alphabets (Parma Eldalamberon 16, 38-39).

What am I talking about already? Here's the quote:

I daresay under grace that [pain which you are feeling] will do good rather than harm, but that is between you and God. It is one of the mysteries of pain that it is, for the sufferer, an opportunity for good, a path of ascent however hard. But it remains an ‘evil’, and it must dismay any conscience to have caused it carelessly, or in excess, let alone wilfully.

The words I've emphasized recall some of the most famous lines in Vergil's Aeneid. In Book 6 of this work, Aeneas must journey to the underworld, but first he receives instructions about the way and its perils:

Tros Anchisiade, facilis descensus Averno:
noctes atque dies patet atri ianua Ditis;
sed revocare gradum superasque evadere ad auras,
hoc opus, hic labor est.

Trojan son of Anchises, easy is the descent to hell:
Night and day the doors of dark Dis lie open;

But to retrace your steps, and escape to the upper world,

this is the task, this the labor.

            (Aen. 6.127-130)

Notice that Tolkien isn't trying to cheer Lewis up here, or to comfort him with platitudes about how they'll get through this. Had Tolkien been trying to do that, and had he been clumsier and more obvious (like me), he would have alluded to another famous passage of Vergil, where Aeneas is trying to encourage his followers after yet another disaster has befallen them. 

“O socii—neque enim ignari sumus ante malorum—
O passi graviora, dabit deus his quoque finem.
Vos et Scyllaeam rabiem penitusque sonantis
accestis scopulos, vos et Cyclopea saxa
experti: revocate animos, maestumque timorem
mittite: forsan et haec olim meminisse iuvabit."

"O my Comrades -- by now we know all about evils
-- You've seen worse! God will let these end, too.
You, you've come near rabid Scylla's baying cliffs;
You've seen the giant stonework of the Cyclops's home.
Take up your courage again, let go dejection and fear:
Perhaps one day it will please us to recall these evils, too."

(Aen. 1.198-203)

Rather than pat Lewis on the back, Tolkien allows that Lewis is in pain, that he (Tolkien) has done him wrong, however unintentionally, and that the way back from this will involve hard work. He knows that when we are hurt even forgiving the offender often doesn't make the pain go away. There are times when we are downhearted because the world is just giving us a hard time; there are times when someone in particular whom we care about hurts us; and there are times when we feel the pain of hurting someone we love and losing them. Encouragement like that given by Aeneas to his followers can help in the first of these scenarios. At least it can encourage us to pull ourselves together and go on. The second and third scenarios are much harder, darker and more hellish. "This is the task, this the labor."
