FILLED with man-purses and tolerance and kaftans draped on the backs of cafe chairs, should the temperature suddenly drop, Copenhagen is notoriously too civilized. At stoplights, bicycles queue with a Tetris-like geometry, and the natives never jaywalk. (Step into one of their bike lanes, and a Dane might sniff at you; but in three days of walking the expanse of Copenhagen, I never once heard a car horn.) How did a city so orderly, so sleepily self-satisfied, ever produce Soren Kierkegaard?
