Bioluminescence and the Art of the Glowing Sentence

There is a mushroom called the jack-o'-lantern, and it glows. Not brightly — a faint greenish light, visible only in full darkness, emanating from the gills. For centuries people told stories about it: ghost lights, fairy lights, will-o'-the-wisps leading travelers astray. The truth is stranger and quieter. The mushroom is not trying to lure anyone. It is simply alive, and its aliveness happens to produce light.

I think about the jack-o'-lantern when I revise my writing. A good sentence, like a bioluminescent mushroom, glows from within. It does not announce itself. It does not use exclamation points or fancy vocabulary. It simply is what it is, and in the right darkness — the darkness of a reader's quiet attention — it becomes visible.

The problem is that glowing sentences are easy to miss. They do not stand out on a page the way a loud sentence does. They require the reader to be in the dark, which is to say, they require the reader to be undistracted. This is why so much contemporary writing is loud instead of luminous: loudness is easier to notice, and noticeability is what the internet rewards.

Finding the Glow in Your Own Work

Here is a revision practice I have borrowed from mycologists. When they want to find bioluminescent fungi, they do not search in daylight — they wait for night and walk slowly, letting their eyes adjust. In the same way, when I want to find the glowing sentences in a draft, I do not read it in my usual critical mode. I read it aloud, in a quiet room, at the end of the day. I do not look for what is wrong. I look for what is alive.

What I find, usually, is that the glowing sentences are the plainest ones. She put the knife down. He did not answer. The rain kept falling. These sentences do not try. They simply are. And in the context of a well-built paragraph, they light the whole thing up.

Writing Prompt: The Darkness Exercise

Take a paragraph you have written and delete every adjective and adverb. Read what remains. Then, one by one, put back only the modifiers that are doing necessary work — the ones that change the meaning, not the ones that decorate it. What you are left with is the glow. It may be smaller than what you started with. It will also be brighter. Keep it. The rest was noise.
