The greatest poet in the English language found his poetry where poetry is found: in the lives of the people. He could have done this only through love — by knowing, which is not the same thing as understanding, that whatever was happening to anyone was happening to him. It is said that his time was easier than ours, but I doubt it — no time can be easy if one is living through it. I think it is simply that he walked his streets and saw them, and tried not to lie about what he saw: his public streets and his private streets, which are always so mysteriously and inexorably connected; but he trusted that connection. And, though I, and many of us, have bitterly bewailed (and will again) the lot of an American writer — to be part of a people who have ears to hear and hear not, who have eyes to see and see not — I am sure that Shakespeare did the same. Only, he saw, as I think we must, that the people who produce the poet are not responsible to him: he is responsible to them.
That is why he is called a poet. And his responsibility, which is also his joy and his strength and his life, is to defeat all labels and complicate all battles by insisting on the human riddle, to bear witness, as long as breath is in him, to that mighty, unnameable, transfiguring force which lives in the soul of man, and to aspire to do his work so well that when the breath has left him, the people — all people! — who search in the rubble for a sign or a witness will be able to find him there.
