Dear Writers,

The following excerpt, which has appeared in several works by the writer Joan Didion over some years, is one of many wonderful passages she has written in describing her writing and her process as a writer. Some writers read at least one of these pieces every year. It’s like a brisk walk.

For reasons which now sound baroque I needed a degree by the end of that summer, and the English department finally agreed, if I would come down from Sacramento every Friday and talk about the cosmology of Paradise Lost, to certify me proficient in Milton. I did this. Some Fridays I took the Greyhound bus, other Fridays I caught the Southern Pacific’s City of San Francisco on the last leg of its transcontinental trip. I can no longer tell you whether Milton put the sun or the earth at the center of his universe in Paradise Lost, the central question of at least one century and a topic about which I wrote ten thousand words that summer, but I can still recall the exact rancidity of the butter in the City of San Francisco’s dining car, and the way the tinted windows on the Greyhound bus cast the oil refineries around Carquinez Strait into a grayed and obscurely sinister light. In short my attention was always on the periphery, on what I could see and taste and touch, on the butter, and the Greyhound bus. During those years I was traveling on what I knew to be a very shaky passport, forged papers: I knew that I was no legitimate resident in any world of ideas. I knew I couldn’t think. All I knew then was what I couldn’t do. All I knew then was what I wasn’t, and it took me some years to discover what I was. . . .

Which was a writer.

By which I mean not a “good” writer or a “bad” writer but simply a writer, a person whose most absorbed and passionate hours are spent arranging words on pieces of paper. Had my credentials been in order I would never have become a writer. Had I been blessed with even limited access to my own mind there would have been no reason to write. I write entirely to find out what I’m thinking, what I’m looking at, what I see and what it means. What I want and what I fear. Why did the oil refineries around Carquinez Strait seem sinister to me in the summer of 1956? Why have the night lights in the Bevatron burned in my mind for twenty years? What is going on in these pictures in my mind?

People on hallucinogens describe the same perception of objects. I’m not a schizophrenic, nor do I take hallucinogens, but certain images do shimmer for me. Look hard enough, and you can’t miss the shimmer. It’s there. You can’t think too much about these pictures that shimmer. You just lie low and let them develop. You stay quiet. . . . you try to locate the cat in the shimmer, the grammar in the picture.

Just as I meant “shimmer” literally I mean “grammar” literally. Grammar is a piano I play by ear, since I seem to have been out of school the year the rules were mentioned.

All I know about grammar is its infinite power. To shift the structure of a sentence alters the meaning of that sentence, as definitely and inflexibly as the position of a camera alters the meaning of the object photographed. Many people know about camera angles now, but not so many know about sentences. The arrangement of the words matters, and the arrangement you want can be found in the picture in your mind. . . The picture dictates whether this will be a sentence with or without clauses, a sentence that ends hard or a dying-fall sentence, long or short, active or passive. The picture tells you how to arrange the words and the arrangement of the words tells you, or tells me, what’s going on in the picture. Nota bene:

It tells you.

You don’t tell it.
