We are all haunted by George Santayana’s famous statement: “Those who cannot remember the past are condemned to repeat it.” We say it often, but is it true?
I welcome others’ opinions, but I have my doubts. Let me offer three reasons:
First, do we ever really understand the past? Could the Civil War—the most deadly war in American history—have been prevented? Possibly. But if so, how would slavery have ended? Avoiding one tragedy might have perpetuated another. So what have we learned about the Civil War that could possibly guide us in the future?
Second, let’s suppose we understand the past. Can we know where to apply that understanding and where not? Nearly everyone agrees that World War I was a pointless war and a horrific tragedy; in contrast, historians generally agree that World War II “had to” be fought, and it was the Allies’ finest hour.
