For some, hope offers ineffectual lip service for change.  Others see hope as a brave stance in the face of a difficult world.  Rabbi Jonathan Sacks gives different names to these diverging views.  “Optimism is a passive virtue, hope an active one. It needs no courage, only a certain naiveté, to be an optimist. It needs a great deal of courage to have hope.”  How can we move hope beyond wishful thinking to life-giving vision?
