“We think our memories are pure and uncorrupted, but this is a delusion. Every time we access a memory we rebuild it. Every time it’s rebuilt, things are added and things are lost. In fact, the more we remember something, the less resemblance that memory bears to the original event. We know that memory is fallible—or we know it, but we don’t really believe it. If someone says we remembered something wrong, we argue over it! We fight for the honor of our memories. Maybe it’s like religion, or love. The more flimsy something is, the more fiercely we believe in it.”
