We know how things are and how they are not. We know how things tend to work and how they don’t. We know how things mostly go and how they never go. And we like it when a story agrees with our sense of how the world works. It gives us a thrill, and this thrill-at-truth keeps us reading. In a story entirely made up, it’s actually the main thing that keeps us reading. Since everything is invented, we read in a continual state of light skepticism. Every sentence is a little referendum on truth. “True or not?” we keep asking. If our answer is “Yes, seems true,” we get shot out of that little gas station and keep reading.

I once asked Ethan Canin to tell me the most valuable thing he knew about writing, and without hesitation he said, "Nothing is as important as a likable narrator. Nothing holds a story together better." I think he’s right. If your narrator is someone whose take on things fascinates you, it isn’t really going to matter if nothing much happens for a long time.

To fashion a persona out of one’s own undisguised self is no easy thing. A novel or a poem provides invented characters or speaking voices that act as surrogates for the writer. Into those surrogates will be poured all that the writer cannot address directly—inappropriate longings, defensive embarrassments, anti-social desires—but must address to achieve felt reality. The persona in a nonfiction narrative is an unsurrogated one. Here the writer must identify openly with those very same defenses and embarrassments that the novelist or the poet is once removed from.

In each case the writer was possessed of an insight that organized the writing, and in each case a persona had been created to serve the insight. I became enraptured, tracing out the development of the persona in memoir after essay after memoir (it was out of this rapture that I realized I was a nonfiction writer). I began to read the greats in essay writing—and it wasn’t their confessing voices I was responding to, it was their truth-speaking personae.

But memoir is neither testament nor fable nor analytic transcription. A memoir is a work of sustained narrative prose controlled by an idea of the self under obligation to lift from the raw material of life a tale that will shape experience, transform event, deliver wisdom. Truth in a memoir is achieved not through a recital of actual events; it is achieved when the reader comes to believe that the writer is working hard to engage with the experience at hand. What happened to the writer is not what matters; what matters is the large sense that the writer is able to make of what happened. For that the power of a writing imagination is required. As V. S. Pritchett once said of the genre, “It’s all in the art. You get no credit for living.
