It is a necessary conceit to believe things cannot change beyond all recognition. To greet the day to come as if it was but a shadow cast forward by the day just done, is how we fashion the links of the chain that we call our lives. But it is in the moment when the world shows a new face, when the chain twists, buckles and binds, when rain turns into fire, water into stone, land into sea, that we must acknowledge a most unpleasant truth. Continuity is an illusion. Unseen forces work to their own ends.
