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.

Burroughs's voice is hard, derisive, inventive, free, funny, serious, poetic, indelibly American.

In fact I no longer value this kind of memento. I no longer want reminders of what was, what got broken, what got lost, what got wasted. There was a period, a long period, dating from my childhood until quite recently, when I thought I did. A period during which I believed that I could keep people fully present, keep them with me, by preserving their mementos, their "things," their totems.

When I began writing these pages I believed their subject to be children, the ones we have and the ones we wish we had, the ways in which we depend on our children to depend on us, the ways in which we encourage them to remain children, the ways in which they remain more unknown to us than they do to their more casual acquaintances; the ways in which we remain equally opaque to them.

Writing nonfiction is more like sculpture, a matter of shaping the research into the finished thing.

This book is called "Blue Nights" because at the time I began it I found my mind turning increasingly to illness, to the end of promise, the dwindling of the days,the inevitability of the fading, the dying of the brightness. Blue nights are the opposite of the dying of the brightness, but they are also its warning.
