... A major theme of [Warren's] The Legacy of the Civil War is that the war left the North (which is to say, the U.S. government) with "a treasury of virtue." This is the "psychological heritage" left to the North, and it is an insidious heritage, wrote [Pulitzer-Prize winning poet and novelist] Robert Penn Warren. "The Northerner, with his Treasury of Virtue, feels redeemed by history." ... Warren called this "moral narcissism." It is "a poor basis for national policy," he wrote, but is the "justification" for "our crusades of 1917-1918 and 1941-1945 and our diplomacy of righteousness, with the slogan of unconditional surrender and universal spiritual rehabilitation for others."
