What does the eye appreciate, the eye that evolved to spot antelope across a distant horizon, the eye that often looks no farther now than the tiny screen of a smart phone?

It likes the greensward, the open expanse of turf, like the swelling savannahs of our evolutionary past. And there, where earth meets sky, if not an animal of prey then an emblem of our ambition: a city to conquer and admire.

I once spent time in this place, the Sheep Meadow of Central Park. In fact, I once lost a set of keys somewhere on this vast lawn. I walked by the meadow daily and mediated on this vista. It is a uniquely American view, embracing our love of cities and of countryside, promising both peace and prosperity. It is a sigh of relief, a gasp of delight.
