“No matter how much time has passed, these things still affect us and the world we live in. If you don't pay attention to the past, you'll never understand the future. It's all linked together.”

Lyra's Oxford (2003)
Context: All these tattered old bits and pieces have a history and a meaning. A group of them together can seem like the traces left by an ionizing particle in a bubble chamber: they draw the line of a path taken by something too mysterious to see. That path is a story, of course. What scientists do when they look at the line of bubbles on the screen is work out the story of the particle that made them: what sort of particle it must have been, and what caused it to move in that way, and how long it was likely to continue.
Dr. Mary Malone would have been familiar with that sort of story in the course of her search for dark matter. But it might not have occurred to her, for example, when she sent a postcard to an old friend shortly after arriving in Oxford for the first time, that that card itself would trace part of a story that hadn't yet happened when she wrote it. Perhaps some particles move backward in time; perhaps the future affects the past in some way we don't understand; or perhaps the universe is simply more aware than we are. There are many things we haven't yet learned how to read.
The story in this book is partly about that very process.

Context: Most things are forgotten over time. Even the war itself, the life-and-death struggle people went through, is now like something from the distant past. We're so caught up in our everyday lives that events of the past, like ancient stars that have burned out, are no longer in orbit around our minds. There are just too many things we have to think about every day, too many new things we have to learn. New styles, new information, new technology, new terminology... But still, no matter how much time passes, no matter what takes place in the interim, there are some things we can never assign to oblivion, memories we can never rub away. They remain with us forever, like a touchstone. And for me, what happened in the woods that day is one of these.
