“This book is not about heroes. English poetry is not yet fit to speak of them.
Nor is it about deeds, or lands, nor anything about glory, honour, might, majesty, dominion, or power, except War.
Above all I am not concerned with Poetry.
'My subject is War, and the pity of War.
The Poetry is in the pity.
Yet these elegies are to this generation in no sense consolatory. They may be to the next. All a poet can do today is warn. That is why the true Poets must be truthful.”

“The Obscurity of the Poet”, p. 3
Poetry and the Age (1953)
Context: When I was asked to talk about the Obscurity of the Modern Poet I was delighted, for I have suffered from this obscurity all my life. But then I realized that I was being asked to talk not about the fact that people don’t read poetry, but about the fact that most of them wouldn’t understand it if they did: about the difficulty, not the neglect, of contemporary poetry. And yet it is not just modern poetry, but poetry, that is today obscure. Paradise Lost is what it was; but the ordinary reader no longer makes the mistake of trying to read it — instead he glances at it, weighs it in his hand, shudders, and suddenly, his eyes shining, puts it on his list of the ten dullest books he has ever read, along with Moby-Dick, War and Peace, Faust, and Boswell’s Life of Johnson. But I am doing this ordinary reader an injustice: it was not the Public, nodding over its lunch-pail, but the educated reader, the reader the universities have trained, who a few weeks ago, to the Public’s sympathetic delight, put together this list of the world’s dullest books.
Since most people know about the modern poet only that he is obscure—i. e., that he is difficult, i. e., that he is neglected — they naturally make a causal connection between the two meanings of the word, and decide that he is unread because he is difficult. Some of the time this is true: the poet seems difficult because he is not read, because the reader is not accustomed to reading his or any other poetry.

Strange Meeting (1918)
Context: "Strange friend," I said, "Here is no cause to mourn."
"None," said the other, "Save the undone years,
The hopelessness. Whatever hope is yours,
Was my life also; I went hunting wild
After the wildest beauty in the world,
Which lies not calm in eyes, or braided hair,
But mocks the steady running of the hour,
And if it grieves, grieves richlier than here.
For by my glee might many men have laughed,
And of my weeping something has been left,
Which must die now. I mean the truth untold,
The pity of war, the pity war distilled.
Now men will go content with what we spoiled.
Or, discontent, boil bloody, and be spilled.
They will be swift with swiftness of the tigress,
None will break ranks, though nations trek from progress.
Courage was mine, and I had mystery;
Wisdom was mine, and I had mastery;
To miss the march of this retreating world
Into vain citadels that are not walled.
