William: A Spark Is Not an Explanation

William had built a small program that turned a tapped rhythm into a shifting pattern of light. It worked. That was the trouble: every change looked obedient, and nothing looked alive.

He had tried longer pauses, uneven intervals, a softer fade. He had listened to the rhythm without watching the screen, then watched without listening. His notebook held enough crossed-out possibilities to show that this was not a problem he had merely wished at.

At last he saved the work and went outside. He did not take the notebook.

There was a useful distinction in the 2014 review Creativity—the unconscious foundations of the incubation period, by Ritter and Dijksterhuis: initial conscious work, then an interval away from task-related conscious thought. Preparation before incubation. The interval was not a substitute for learning the shape of the difficulty.

The authors interpreted the findings they reviewed as supporting an unconscious contribution to creativity, considering mind-wandering and sleep as well as explanations based on distraction alone. William could take that interpretation seriously without making it the explanation for every bright thought he had ever had. Feeling a solution arrive did not let him observe everything that had brought it there.

Beyond the screen, he noticed the ordinary unevenness of walking: a footfall, a small hesitation at the curb, the next step. For a moment he wondered whether the light should answer the rhythm rather than follow it.

It was only a possibility. He would have to build it, watch it, and perhaps cross it out.

Still, there was warmth in the arrival. He could call that warmth a divine spark—a name for how an opening felt, not evidence of a supernatural cause. The metaphor did not need to become a mechanism to matter to him.

Nor did the walk need to earn its keep by producing an answer. Some evenings the stubborn thing would remain stubborn. Music, air, and movement would still belong to his life, not merely to a technique for getting more work out of it.

When William returned, the screen held exactly what he had left. He opened the notebook before changing the code.
