“It’s all about the direction of time, and the direction of us as we move through it.”
“I don’t follow.”
“It’s this: We’re walking backwards through time.”
He pause to let us think about this.
“Most of us can see everything that has happened but nothing that will happen,” he explained with dazzling directness, “like walking backwards. You wouldn’t think to drive a car forwards while facing backwards, so it would make more sense to walk forwards through time, don’t you think?”
It was an interesting point.
“But then our past would be unknown to us,” I pointed out.
“Is that so bad? To remember everything that is going to happen is better than remembering everything that has.”
I must have looked doubtful, for he added:
“Okay, which is better: The anticipation of a really good time or the memory of it?”
“The anticipation, I guess.”
“I think so too,” he said sadly, “we’re travelling through time facing the wrong direction. If we could only turn around and look occasionally where we were going, things would be a lot simpler.”
