Princeton African American Studies professor Imani Perry says the South can be seen as an "origin point" for the way the nation operates. Her book, South to America, reflects on the region's history and traces the steps of an enslaved ancestor. "The South in some ways becomes the repository for the nation's sins, right?" she says. "And then it allows the rest of the country to conceive of itself as relatively pristine."Also, Justin Chang reviews the Finnish film Compartment No. 6.
