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.

If William Hazlitt hadn’t awakened each morning crawling inside his own skin, he could not have written “On the Pleasure of Hating.” If Virginia Woolf didn’t have difficulty attaching herself to life, she would not have written “The Death of the Moth.” If James Baldwin wasn’t in perpetual violent struggle to bring the black and the white inside himself under control, there would be no “Notes of a Native Son.” These pieces are the work of writers engaged at the deepest level with the essay.

Didion’s “essay” into herself tells us a thing we all know to be true: that the power of everyday anxiety is ruthless: it makes us act against our own well-being, sometimes it even makes us court perversity, a thing we are ashamed of, can hardly bear to look at.

The writing continues to dazzle while the structure falls apart. And rightly so. Because, after all, what difference does it really make—the second and third times around—which comes first? We are in the presence of a man in a trance of self-analysis: a man who will never act on what he knows and therefore is compelled to go on “knowing.

From the moment I found myself standing in front of a memoir-writing class with a hunk of manuscript in my hand, asking, What is this all about? —and the answer came back, It’s about this dysfunctional family in Cincinnati, and I said, No, no. What is it about?—I saw that my classes would be reading as I needed to read: looking for the inner context that makes a piece of writing larger than its immediate circumstance; places a writer’s thought and feeling; imposes shape and reveals inner purpose; the thing that is invariably being addressed when one says to any writer of imagination, But what is it about? and does not expect to hear, It’s about this family in Cincinnati.
