The Economist reported that in early 2007, for the first time in history, more humans lived in cities than in the countryside.

Years back, conversing with a now long-retired dean, I happened to let slip the words “common sense.” He replied, “It’s been a long time since I heard that phrase uttered on this campus, much less seen it practiced.”

Though a few verbal grenades are tossed over the divide each semester, schools on both sides generally co-exist tolerably well. What are the differences between them?
