" Still, picture the noble snake, having molted, slithering away, newly glistening. There’s the skin, in a big disorganized pile behind it. Is the snake asking you to notice that a snake was here earlier? No; the snake doesn’t care one way or the other. It has moved on. No, indeed, you can’t call a snake sloppy or careless or fault it for leaving tracks in its wake. Besides, who are you? Snakes have been here for millions of years. "
