I don't think anybody can teach anybody anything. I think that you learn it, but the young writer that is as I say demon-driven and wants to learn and has got to write, he don't know why, he will learn from almost any source that he finds. He will learn from older people who are not writers, he will learn from writers, but he learns it -- you can't teach it.
Evan Connell said once that he knew he was finished with a short story when he found himself going through it and taking out commas and then going through the story again and putting the commas back in the same places. I like that way of working on something. I respect that kind of care for what is being done. That's all we have, finally, the words, and they had better be the right ones, with the punctuation in the right places so that they an best say what they are meant to say. If the words are heavy with the writer's own unbridled emotions, or if they are imprecise and inaccurate for some other reason -- if the worlds are in any way blurred -- the reader's eyes will slide right over them and nothing will be achieved. Henry James called this sort of hapless writing 'weak specification'.
V.S. Pritchett's definition of a short story is 'something glimpsed from the corner of the eye, in passing.' Notice the 'glimpse' part of this. First the glimpse. Then the glimpse gives life, turned into something that illuminates the moment and may, if we're lucky -- that word again -- have even further ranging consequences and meaning. The short story writer's task is to invest the glimpse with all that is in his power. He'll bring his intelligence and literary skill to bear (his talent), his sense of proportion and sense of the fitness of things: of how things out there really are and how he sees those things -- like no one else sees them. And this is done through the use of clear and specific language, language used so as to bring to life the details that will light up the story for the reader. For the details to be concrete and convey meaning, the language must be accurate and precisely given. The words can be so precise they may even sound flat, but they can still carry; if used right they can hit all the notes.
It's possible, in a poem or a short story, to write about commonplace things and objects using commonplace but precise language, and to endow those things-- a chair, a window curtain, a fork, a stone, a woman's earring-- with immense, even startling power. It is possible to write a line of seemingly innocuous dialogue and have it send a chill along the reader's spine-- the source of artistic delight, as Nabokov would have it. That's the kind of writing that most interests me.
