Poems on Poems

Here is a little quote by the famous poetry critic Helen Vendler commenting upon someone else's criticism that "every Ashbery poem is about poetry." :

In the code language of criticism when a poem is said to be about poetry the word "poetry" is often used to mean: how people construct an intelligibility out of the randomness they experience; how people choose what they love; how people integrate loss and gain; how they distort experience by wish and dream; how they perceive and consolidate flashes of harmony; how they (to end a list otherwise endless) achieve what Keats called a "Soul or Intelligence destined to possess the sense of Identity."
