I know a man who once went to Sioux City, not one of the world’s leading destinations, precisely because he had never been there before. More than a decade later he still talks about the experience, from the Sergeant Floyd obelisk to the dog track of North Sioux and the meat packing plant converted to a shopping mall. The same impulse explains a non-specialist’s reading a history of Byzantine iconography or a survey of Australian wildlife. Both offer a break in daily life and an enlargement of our sense of wonder and possibility. That awareness can provide a sense of transcendence, and connection, or even the spark of divine discontent that leads people to change their lives.
