Something nonsensical in the heart of poetry
Something nonsensical in the heart of poetry is the very reason why one can’t call poetry “useful.” Sense is useful; you can apply things that make sense to other circumstances; you can take something away. But nonsense you can only revisit; its satisfactions exist in it, and not in applications. This is why Auden and others can say with such confidence that poetry makes nothing happen. That’s the relief of it. And the reason why nothing can substitute for it.
