If Only

In an essay discussing his experiences on a cruise ship ("A Supposedly Fun Thing I'll Never Do Again") David Foster Wallace talks about the "prettiness" of the Caribbean. Then this footnote (#73, on page 306 of the collection of which this is the title essay):
It is not "beautiful"; it is "pretty". There's a difference.
Imagine how much clearer, how much more telling our art criticism would be if we kept this crucial idea in mind.
