“I know what evil is. Once or twice I have wrestled with it, and for a time felt its chilling touch on my life; so I speak with knowledge when I say that evil is of no consequence, except as a sort of mental gymnastic.
For the very reason that I have come in contact with it, I am more truly an optimist. 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 overcoming 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 coöperate with the good, that it may prevail.
I try to increase the power God has given me to see the best in everything and every one, and make that Best a part of my life. The world is sown with good; but unless I turn my glad thoughts into practical living and till my own field, I cannot reap a kernel of the good.”
