quite extraordinary Nobel acceptance speech (taped in a London studio, since he is too ill to travel to Stockholm) is up at the Guardian. Here's the meat of his comments about his own way of writing, though there's lots of other stuff there worth reading too (including an incredibly depressing indictment of American foreign policy, as you might expect):
I have often been asked how my plays come about. I cannot say. Nor can I ever sum up my plays, except to say that this is what happened. That is what they said. That is what they did.
Most of the plays are engendered by a line, a word or an image. The given word is often shortly followed by the image. I shall give two examples of two lines which came right out of the blue into my head, followed by an image, followed by me.
The plays are The Homecoming and Old Times. The first line of The Homecoming is 'What have you done with the scissors?' The first line of Old Times is 'Dark.'
In each case I had no further information.
In the first case someone was obviously looking for a pair of scissors and was demanding their whereabouts of someone else he suspected had probably stolen them. But I somehow knew that the person addressed didn't give a damn about the scissors or about the questioner either, for that matter.
'Dark' I took to be a description of someone's hair, the hair of a woman, and was the answer to a question. In each case I found myself compelled to pursue the matter. This happened visually, a very slow fade, through shadow into light.
I always start a play by calling the characters A, B and C.
In the play that became The Homecoming I saw a man enter a stark room and ask his question of a younger man sitting on an ugly sofa reading a racing paper. I somehow suspected that A was a father and that B was his son, but I had no proof. This was however confirmed a short time later when B (later to become Lenny) says to A (later to become Max), 'Dad, do you mind if I change the subject? I want to ask you something. The dinner we had before, what was the name of it? What do you call it? Why don't you buy a dog? You're a dog cook. Honest. You think you're cooking for a lot of dogs.' So since B calls A 'Dad' it seemed to me reasonable to assume that they were father and son. A was also clearly the cook and his cooking did not seem to be held in high regard. Did this mean that there was no mother? I didn't know. But, as I told myself at the time, our beginnings never know our ends.
'Dark.' A large window. Evening sky. A man, A (later to become Deeley), and a woman, B (later to become Kate), sitting with drinks. 'Fat or thin?' the man asks. Who are they talking about? But I then see, standing at the window, a woman, C (later to become Anna), in another condition of light, her back to them, her hair dark.
