In our relentlessly optimized world, Justin Neuman calls for more nothing. More time for both adults and kids to engage in free, unstructured play. More opportunities to play games without competition or scoring. More chances to do things without needing to produce outputs or achieve goals. More “transitional spaces” through which we can practice, imagine, and think.

For years, I’ve commuted on foot from Grand Central Station to 14th Street, 30 blocks, give or take. I told myself it was exercise, or that I was saving the subway fare, or that I liked the air. But the truth is I was thinking. Or rather, I was letting thinking happen. The lecture I couldn’t outline at my desk would assemble itself somewhere around 34th Street, the important points falling into sequence with my footfalls, the argument clarifying as if the motion itself were doing the editing. I wasn’t working on the lecture. I was walking in it, the way my kids were playing in Catan.
