I can say with conviction that the struggle which evil necessitates is one of the greatest blessings. It makes us strong, patient, helpful men and women. It lets us into the soul of things and teaches us that although the world is full of suffering, it is full also of the overcomings of it. My optimism, then, does not rest on the absence of evil, but on a glad belief in the preponderance of good and a willing effort always to cooperate with the good, that it may prevail.
