Wrongs are often forgiven, but contempt never is.
                            Our pride remembers it forever.
                                                            - Lord Chesterfield

   It is not "forgive and forget" as if nothing wrong had ever happened, but "forgive and go forward," building on the mistakes of the past and the energy generated by reconciliation to create a new future.
                                                           - Carolyn Osiek, Beyond Anger
 
 

... whoever closes his eyes to the past becomes blind to the present.
Whoever does not wish to remember inhumanity becomes susceptible
to the dangers of new infection.
... there can be no reconciliation without memory.
                                                           - Richard Von Weizaecker
 

                            It is by forgiving that one is forgiven.
                                                            - Mother Teresa
 

                    The salvation of
                                     man is through love and in love.
                                                            - Viktor Frankl
