The willingness and courage to be aware of and experience the dark side of life, and the consequent despair we feel when we do so, is what distinguishes authentic faith from wishful thinking and denial. Despair is faith's darker handmaiden. There is no faith without doubt and despair, just as there is no good without evil, no day without night. To be authentic, faith must be all-inclusive — encompassing Auschwitz as much as it encompasses its dreams of paradise.
