Lewis Carroll’s Through the Looking Glass, the White Queen instructs Alice that “one’s memory works both ways.” “I’m sure mine only works one way,” Alice remarked. “I can’t remember things before they happen.” “It’s a poor sort of memory that only works backwards,” the Queen remarked. “What sort of things do you remember best?” Alice ventured to ask. “Oh, things that happened the week after next,” the Queen replied in a careless tone.
