"You have seen the puzzle of the Paper Ring? Where you take a a slip of paper, join its ends together, first twisting one, so as to join the upper corner of one end to the lower corner of the other? The Ring has only one surface, and only one edge. The Sock is just like that, isn't it? Is not the outer surface of one side of it continuous with the inner surface of the other side? Whatever is inside that Sock, is outside it; and whatever is outside it, is inside it!"
