" I suppose memories live here and there in the body," the old man said, moving his hand from his chest to the top of his head. "But they're invisible, aren't they? And no matter how wonderful the memory, it vanishes if you leave it alone, if no one pays attention to it. They leave no trace, no evidence that they ever existed. But I suppose you're right when you say we should do everything we can to bring back memories of the things that have disappeared. "
