I think it was when I got to the butterflies -- in that brief, beautiful image comprising life, death and technology -- that the hair on the back of my neck began to stand on end. All at once, the pleasure I took in reading was altered irrevocably. Before then I had never noticed, somehow, that stories were made not of ideas or exciting twists of plot but of language. And not merely of pretty words and neat turns of phrase, but of systems of imagery, strategies of metaphor.

When I first set my sights on becoming a writer at age eleven or so, I wanted to be a fantasy and science fiction writer. That was my preferred reading material and that's what I thought I was going to write. That's always been there. You can even see little hints of it in Mysteries of Pittsburgh and Wonderboys.

I have staked my career—my life itself—on the things I could see, on the stories I could credit, and on the eventual vindication, when the book was closed, of the reasonable and skeptical approach. In the face of twenty-five years of bloodshed, mayhem, criminality, and the universal human pastime of ruination, I have clung fiercely to Occam’s razor, seeking always to keep my solutions unadorned and free of conjecture, and never to resort to conspiracy or any kind of prosecutorial woolgathering. My mother, whenever she was confronted by calamity or personal sorrow, invoked cosmic emanations, invisible empires, ancient prophecies, and intrigues; it has been the business of my life to reject such folderol and seek the simpler explanation. But we were fools, she and I, arrant blockheads, each of us blind to or heedless of the readiest explanation: that the world is an ungettable joke, and our human need to explain its wonders and horrors, our appalling genius for devising such explanations, is nothing more than the rim shot that accompanies the punch line.
