"The Civil War is not only the central event of American history, but it's a central event in large ways for the world itself. If we believe today in the 20th century, as surely we must, that popular government is the way to go, it is the way to the emancipation of the human spirit; then the Civil War established the fact that a popular government could survive, that it could overcome an internal secession movement that could destroy it. So the war becomes, in essence, it becomes a testament for the liberation of the human spirit for all time."
