Speak not evil one of another, breathren.
                              -  James iv.ii

Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice.
                                - Eph, iv. 31


        If aught good thou canst not say
          Of thy brother, foe, or friend,
      Take thou, then, the silent way,
          Lest in word thou shouldst offend.
                                                  Anon

IF there is any person to whom you feel dislike, that is the person of whom you ought never to speak.
                                            R. Cecil

To recognize with delight all high and generous and beautiful actions; to find a joy even in seeing the good qualities of your bitterest opponents, and to admire those qualities even in those with whom you have least sympathy, this is the only spirit which can heal the love of slander and of calumny.
