Lewis P. Simpson 
Fable of the Southern Writer [PDF ebook] 

"With a breadth and depth unsurpassed by any other cultural historian of the South, Lewis Simpson examines the writing of southerners Thomas Jefferson, John Randolph, Mark Twain, Robert Penn Warren, Allen Tate, William Faulkner, Elizabeth Madox Roberts, Arthur Crew Inman, William Styron, and Walker Percy. Simpson offers challenging essays of easy erudition blessedly free of academic jargon…. [They] do not propose to support an overall thesis, but simply explore the southern writer’s unique relationship with his or her region, bereft of myth and tradition, in the grasp of science and history." — Library Journal
