Those who don't know history are doomed to repeat it

"The mistake we all make is in assuming anybody remembers <i>any</i>damnthing from one day to the next. If that were true, we'd stop getting involved with approximately the same kind of wrong lover each time, we'd learn the lessons of history, the death penalty would discourage those plotting murder, and George Santayana's famous quote would be about as popular as "the bee's knees." But few of us keep accurate records of what we've learned as we hobble through life barking our shins in the dark on experiences we've already had...."

Those who fail to learn from history are doomed to repeat it.

Those who cannot remember the past are condemned to repeat it.

It is said that those who fail to remember history are doomed to repeat it. That’s not quite correct. We all forget history. The key is whether we have a way to go back to rediscover what we forget. More directly, the key is whether an objective past can keep us honest.

Perhaps you have forgotten. That’s one of the great problems of our modern world, you know. Forgetting. The victim never forgets. Ask an Irishman what the English did to him in 1920 and he’ll tell you the day of the month and the time and the name of every man they killed. Ask an Iranian what the English did to him in 1953 and he’ll tell you. His child will tell you. His grandchild will tell you. And when he has one, his great-grandchild will tell you too. But ask an Englishman — ” He flung up his hands in mock ignorance. “If he ever knew, he has forgotten. ‘Move on!’ you tell us. ‘Move on! Forget what we’ve done to you. Tomorrow’s another day!’ But it isn’t, Mr. Brue.” He still had Brue’s hand. “Tomorrow was created yesterday, you see. That is the point I was making to you. And by the day before yesterday, too. To ignore history is to ignore the wolf at the door.

There's an old saying about those who forget history. I don't remember it, but it's good.

In the words of a very famous dead person, 'A nation that does not know its history is doomed to do poorly on the Scholastic Aptitude Test.

And while forgetting the past might condemn people to repeat it, remembering it too vividly condemned them to never leave.

"Remembering's dangerous. I find the past such a worrying, anxious place. "The Past Tense," I suppose you'd call it. Memory's so treacherous. One moment you're lost in a carnival of delights, with poignant childhood aromas, the flashing neon of puberty, all that sentimental candy-floss... the next, it leads you somewhere you don't want to go. Somewhere dark and cold, filled with the damp ambiguous shapes of things you'd hoped were forgotten. Memories can be vile, repulsive little brutes. Like children I suppose. But can we live without them? Memories are what our reason is based upon. If we can't face them, we deny reason itself! Although, why not? We aren't contractually tied down to rationality! There is no sanity clause! So when you find yourself locked onto an unpleasant train of thought, heading for the places in your past where the screaming is unbearable, remember there's always madness. Madness is the emergency exit… you can just step outside, and close the door on all those dreadful things that happened. You can lock them away… forever."

One is astonished in the study of history at the recurrence of the idea that evil must be forgotten, distorted, skimmed over. The difficulty, of course, with this philosophy is that history loses its value as an incentive and example; it paints perfect men and noble nations, but it does not tell the truth.

Learn from history or you're doomed to repeat it.
