Perhaps play is more pervasive than some would like to admit. Think about the world's most impressive architecture, the cleverest industrial design, scientific research that forms unexpected bridges between fields of research, works of writing that expand our definition of American letters. Our first experiences of real play occur when we are young, and we assume that we must grow out of the things from our childhood as larvae will shed their skin in order to get bigger, but we have wrongly categorized this essential thing. It is a skill as well as an activity, and we must not shed our first line of defense against the stripping of our freedom. Play is as crucial and serious as maintenance.
