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.

It occurs to me as I write that this "white light," usually presented dippily (evidence of afterlife, higher power), is in fact precisely consistent with the oxygen deficit that occurs as blood flow to the brain decreases. "Everything went white," those whose blood pressure has dropped say of the instant before they faint.

Mourning has its place but also its limits.

It is impossible to think of Howard Hughes without seeing the apparently bottomless gulf between what we say we want and what we do want, between what we officially admire and secretly desire, between, in the largest sense, the people we marry and the people we love. In a nation which increasingly appears to prize social virtues, Howard Hughes remains not merely antisocial but grandly, brilliantly, surpassingly, asocial. He is the last private man, the dream we no longer admit.

I don't write for catharsis; I have to write to understand.

When you lose someone, a whole lot of perfectly normal circumstances suddenly take on different meaning. You see it in a different light. You wonder if they knew. I wondered. Doctors have told me that people do have a sense of their own approaching death.

Writing is always a way, for me, of coming to some sort of understanding that I can't reach otherwise.It forces you to think. It forces you to work the thing through. Nothing comes to us out of the blue, very easily.
