That’s a key moment in the movie. It is also something that I wish more people would take to heart—people I talk with about politics, especially people I agree with. Today, as in 1865, people tend to be sure they are right, and maybe they are—Stevens was, courageously. What people don’t always want to take on board is that people who disagree with them may be just as resolutely sure they are right. That’s one reason the road to progress, or regression, in a democracy is seldom straight, entirely open or, strictly speaking, democratic. If Lincoln’s truth is marching on, it should inspire people to acknowledge that doing right is a tricky proposition. “I did not want to make a movie about a monument,” Spielberg told me. “I wanted the audience to get into the working process of the president.”
Lincoln came out against slavery in a speech in 1854, but in that same speech he declared that denouncing slaveholders wouldn’t convert them. He compared them to drunkards, writes Goodwin:
Though the cause be “naked truth itself, transformed to the heaviest lance, harder than steel” [Lincoln said], the sanctimonious reformer could no more pierce the heart of the drinker or the slaveowner than “penetrate the hard shell of a tortoise with a rye straw. Such is man, and so must he be understood by those who would lead him.” In order to “win a man to your cause,” Lincoln explained, you must first reach his heart, “the great high road to his reason.”
As it happened, the fight for and against slave-owning would take the lowest of roads: four years of insanely wasteful war, which killed (by the most recent reliable estimate) some 750,000 people, almost 2.5 percent of the U.S. population at the time, or the equivalent of 7.5 million people today. But winning the war wasn’t enough to end slavery. Lincoln, the movie, shows how Lincoln went about avoiding swamps and reaching people’s hearts, or anyway their interests, so all the bloodshed would not be in vain.
