"So when people say that poetry is merely a luxury for the educated middle classes, or that it shouldn't be read much at school because it is irrelevant, or any of the strange and stupid things that are said about poetry and its place in our lives, I suspect that the people doing the saying have had things pretty easy. A tough life needs a tough language - and that is what poetry is. That is what literature offers - a language powerful enough to say how it is.
Let's not confuse this with realism. The power does not lie directly with the choice of subject or its social relevance - if it did, then everything not about our own contemporary situation would be academic to us, and all the art of the past would be a mental museum. Art lasts because it gives us a language for our inner reality, and that is not a private hieroglyph; it is a connection across time to all those others who have suffered and failed, found happiness, lost it, faced death, ruin, struggled, survived, known the night-hours of inconsolable pain."
