“I do the very best I know how—the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what is said against me won’t amount to anything. If the end brings me out wrong, ten angels swearing I was right would make no difference.”
—Lincoln quoted in Francis Carpenter, The Inner Life of Abraham Lincoln: Six Months at the White House.
