Start with the University. You must, because its gravitational force–money, prestige, vision–is what constitutes Hyde-Park-as-such in the first place, gives it its distinctive topography and limits. Without the UofC, Hyde Park would long ago have dissolved into the surrounding South Side. And yet the University’s directive force only sculpts the neighborhood-scape to a certain extent. Into its crevices and blind spots, the South Side languidly but ineluctably flows, filling in available space, moving over when diverted, then back again.
