“We hate poetry that has a palpable design upon us — and if we do not agree, seems to put its hand in its breeches pocket. Poetry should be great and unobtrusive, a thing which enters into one's soul, and does not startle or amaze with itself, but with its subject.”

The Usurpation Of Language (1910)
Context: Though science makes no use for poetry, poetry is enriched by science. Poetry “takes up” the scientific vision and re-expresses its truths, but always in forms which compel us to look beyond them to the total object which is telling its own story and standing in its own rights. In this the poet and the philosopher are one. Using language as the lever, they lift thought above the levels where words perplex and retard its flight, and leave it, at last, standing face to face with the object which reveals itself.

Stephen Hero (1944)
Context: Now for the third quality. For a long time I couldn't make out what Aquinas meant. He uses a figurative word (a very unusual thing for him) but I have solved it. Claritas is quidditas. After the analysis which discovers the second quality the mind makes the only logically possible synthesis and discovers the third quality. This is the moment which I call epiphany. First we recognise that the object is one integral thing, then we recognise that it is an organised composite structure, a thing in fact: finally, when the relation of the parts is exquisite, when the parts are adjusted to the special point, we recognise that it is that thing which it is. Its soul, its whatness, leaps to us from the vestment of its appearance. The soul of the commonest object, the structure of which is so adjusted, seems to us radiant. The object achieves its epiphany.

The Life of Poetry (1949)
Context: Poetry is not; or seems not to be. But it appears that among the great conflicts of this culture, the conflict in our attitude toward poetry stands clearly lit. There are no guards built up to hide it. We call see its expression, and we can see its effects upon us. We can see our own conflict and our own resource if we look, now, at this art, which has been made of all the arts the one least acceptable.
Anyone dealing with poetry and the love of poetry must deal, then, with the hatred of poetry, and perhaps even Ignore with the indifference which is driven toward the center. It comes through as boredom, as name-calling, as the traditional attitude of the last hundred years which has chalked in the portrait of the poet as he is known to this society, which, as Herbert Read says, "does not challenge poetry in principle it merely treats it with ignorance, indifference and unconscious cruelty."
Poetry is foreign to us, we do not let it enter our daily lives.
