Central Park is in fine shape today, but the project still has a social value, in gathering people together for their shared pleasure. Some purists will complain that the art spoils a sanctuary, that the park is perfect as it is, which it is. But the work, I think, pays gracious homage to Olmsted's and Vaux's abiding pastoral vision: like immense Magic Marker lines, the gates highlight the ingenious and whimsical curves, dips and loops that Olmsted and Vaux devised as antidotes to the rigid grid plan of the surrounding city streets and, by extension, to the general hardships of urban life.
The gates, themselves a cure for psychic hardship, remind us how much those paths vary, in width, and height, like the crowds of people who walk along them. More than that, being so sensitive to nature, they make us more sensitive to its effects.
We didn't need the gates to make us sensitive, obviously. Art is never necessary. It is merely indispensable.
At its best, it leads us toward places we might not have thought to visit. Victor Hugo once said, "There is nothing more interesting than a wall behind which something is happening." This also applies to gates, which beckon people to discover what is beyond them.
