Pick of the week

Paul Chan: My laws are my whores. A provocative juxtaposition of ideas and objects that brings together an 18th Century French libertine with 21st Century law in the United States. One of the more difficult exhibitions in town. Its strongest component is a series of fonts that can be downloaded from the artist’s Web site (nationalphilistine.com); drawings and video pieces succeed only fitfully. Through April 12 at the Renaissance Society at the University of Chicago, 5811 S. Ellis Ave.; 773-702-8670.
