The story we believe we consciously know is never the whole story which is unfolding in our lives. Though this may be self-evident when written down like this, the human tendency is to believe that we know the whole story, while the story is occurring in our lives.
In this way many of us are afflicted by hubris. We are self-deceiving and arrogant because we believe and act as if we know the whole.
The developmental counter to this form of hubris is suffering. Suffering more often than not teaches us that we do not know. In this way suffering has value in our lives, even though it does not feel very good at the time.
