"Human suffering is so great, so endless, so awful that I can hardly write of it. I could not go into hospitals and face it, as some do, lest my mind should be temporarily overcome. The whole and the worst the worst pessimist can say is far beneath the least particle of the truth, so immense is the misery of man. It is the duty of all rational beings to acknowledge the truth. There is not the least trace of directing intelligence in human affairs. This is a foundation of hope, because, if the present condition of things were ordered by a superior power, there would be no possibility of improving it for the better in the spite of that power. Acknowledging that no such direction exists, all things become at once plastic to our will."
