“Your memory is a monster; you forget—it doesn't. It simply files things away. It keeps things for you, or hides things from you—and summons them to your recall with will of its own. You think you have a memory; but it has you!”

“you can’t just move backward. You can’t push the chicken back into the egg, wine back into the grape, the boy back into the womb. If you want the baby to let go of your watch, you don’t just try to explain that he ought to do it—you offer him something he would rather have.”
― Isaac Asimov, The Gods Themselves
