[O]ne reason there is no socialism in America is because of Lincoln. In the American context Lincoln imparted to liberal democracy a sense of nobility and purpose that it has not always had in other contexts. He makes democracy something transcendent, and especially at Gettysburg where he talks about the nation having this new birth of freedom. He ratchets the horizons of liberal democracy right up past the spires of Cologne Cathedral and he makes it this glowing attractive ideal that people are willing to make these tremendous sacrifices to protect. Because at the end of the day this is what the Civil War is about-it's about the preservation of liberal democracy. In the 1860s the United States was the last Enlightenment experiment that was still standing. What you had in the climate of mid-19th century Europe was the renaissance of romantic aristocracy.
