When Barack Obama was born, John Kennedy was president. When John Kennedy was born, Woodrow Wilson was president. And when Woodrow Wilson was born, Abe Lincoln was still just a country lawyer, almost unheard of outside Illinois.
The past is closer than we think. But it is also, in another sense, farther away.
One hundred fifty years ago this week — only two average lifetimes ago — Americans butchered one another with frenzied abandon on picturesque fields and hillocks near Gettysburg, Pa. The 160,000 men who fought there on July 1-3, 1863, made up slightly more than one half of one percent of the nation's entire population at the time.
A proportionately sized battle today would throw 1.6 million Americans against one another — and leave 78,000 of them dead.
The scale of the American Civil War overpowers the modern imagination. Gettysburg, its largest and most decisive battle, was not its deadliest.
What was still a young and experimental nation (when Lincoln was born, the author of the Declaration of Independence was still in the White House), with just 31 million residents (less than the current population of California), inflicted upon itself what remains by far America's bloodiest conflict, even in simple numbers. In relative terms, the Civil War was six times as deadly for Americans as World War II.
A comparably scaled internal war today would kill 7 million.
It can feel presumptuous to reflect on the meaning of the Civil War. An oceanic tide of literature, scholarship and dramatization has surely said it all. The astounding eloquence of the participants, from Lincoln on down, bids us to be silent.
