I myself have always found that if I examine something, it's less scary. I grew up in the West, and we always had this theory that if you saw - if you kept the snake in your eye line, the snake wasn't going to bite you. And that's kind of the way I feel about confronting pain. I want to know where it is.

But the fact of it was that I liked it out there, a ruin devoid of human vanities, clean of human illusions, an empty place reclaimed by the weather where a woman plays an organ to stop the wind's whining and an old man plays ball with a dog named Duke. I could tell you that I came back because I had promises to keep, but maybe it was because nobody asked me to stay.

Marriage is memory, marriage is time. Marriage is not only time: it is also, parodoxically, the denial of time.

Information is control.

I recall an August afternoon in Chicago in 1973 when I took my daughter, then seven, to see what Georgia O’Keeffe had done with where she had been. One of the vast O’Keeffe ‘Sky Above Clouds’ canvases floated over the back stairs in the Chicago Art Institute that day, dominating what seemed to be several stories of empty light, and my daughter looked at it once, ran to the landing, and kept on looking. "Who drew it," she whispered after a while. I told her. "I need to talk to her," she said finally.

I was supposed to have a script, and had mislaid it. I was supposed to hear cues, and no longer did. I was meant to know the plot, but all I knew was what I saw: flash pictures in variable sequence, images with no 'meaning' beyond their temporary arrangement, not a movie but a cutting-room experience.

On the whole, I don't want to think too much about why I write what I write. If I know what I'm doing ... I can't do it.
