I intended to write a piece on poetry yesterday, but instead I experienced a tear in my retina. Right eye. Noonish. I saw white lights like fireworks, followed by a hovering gray blob that obscured my vision. It was roughly the shape of an acorn cap or a winter hat with a fuzzy ball on top. An ophthalmologist at KU Medical Center saw me right away. He looked deep into my vitreous gel with a fancy headlamp that made him look like he was about to go spelunking and exclaimed, I see the acorn in your eye! I thought he was making a joke, but apparently he could see a bundle of proteins torn from my retinal lining floating in the gel.

Why does the poetic image communicate faster than other forms? A few years ago, I asked this very question on Facebook and then proceeded to answer it myself. How annoying of me. My answer was as follows:

Arthur Koestler has an interesting theory. He says poetry requires thinking on a third plane, a kind of “bisociation,” meaning perceiving a situation or an idea in two individually consistent but habitually incompatible frames of reference. This bisociation disturbs our patterns of thinking/feeling and causes a crisis, which requires a third plane of thinking/feeling to arise, one that is antithetical to but that does not negate the strife of the two.

Since this moment of entry into the poem is a moment of crisis, I would argue that we respond to the crisis the way we are hard-wired to respond to all crises—as quickly as possible. Our entry into the poem is similar to pulling a hand away from a scalding object before realizing on a conscious level that the object is hot. It’s instinctual, a survival tactic. Perhaps bisociation in poetry works on this level as well—because of the crisis the poem presents, we move swiftly to a different mode of thinking/feeling that allows us to enter the poem without completely fracturing our identities, without obliterating our ways of seeing and moving through the world. Bisociation is a way of surviving the poem, of seeing the world as we experience it on a day-to-day level, then seeing the world of the poem itself, then seeing a plane on which to stand, one that straddles the two and gives the reader a place to exist, to breathe.

Perhaps this is why poems work on us so quickly, why the image communicates faster in poetry than in other forms of writing. Precisely because poems put us in crisis.

I removed that post from Facebook years ago, but I stashed it in my poetry files. I came across it today and appreciated it as one way to understand how poems work. I also appreciated my former self for leaving me this trace. It could prove useful when people ask me what poems are, how the mean, and under what conditions they operate.

If you look at a vertical sagittal section of the human eye, you are supposed to see something that resembles a camera. That’s not what I see. I see an angelfish without the fins. I’m sure this says something fundamental about me. The watery fish in the head. The brain home to an aquarium. The two specimens that cannot swim, that cannot escape, that do my bidding, that are forced to document the production.

In his poem “Trace,” Eric Pankey writes: To occupy space is to shape it. / Snow, slantwise, is not white / But a murk of winter-black basalt. / In the gullied, alluvial distances, / On the swallow-scored air, / Each erasure is a new trace.

Having a torn retina is not without its consequences. I feel like a mean girl punched me in the eye. Maybe at a bar. Maybe after I looked at her the wrong way. Maybe after she mistook the fireworks in my eyes for something I never intended.

If you look closely enough at a poem while wearing a headlamp, you can enter its recesses and observe the detail held within its vitreous gel. What drifts and where. What has lost viscosity with age and use. What holds fast. But when you occupy the poem, you change it. We change things by looking. There is no way around this.

When I told my husband about my retina, he asked if reading poetry might have caused the tear. I said poetry had no bearing on what happened. He seems to think poetry leads to disaster. I’ve tried to tell him for years now that we all lead ourselves to disaster, with or without poetry. Poems simply document the path from cradle to grave; from point of entry to point of no exit; from one dark, craggy landmark to another.
