When nature removes a great man, people explore the horizon for a successor; but none comes, and none will. His class is extinguished with him. In some other and quite different field, the next man will appear.
I shall do less whenever I shall believe what I am doing hurts the cause and I shall do more whenever I shall believe doing more will help the cause. I shall try to correct errors when shown to be errors and I shall adopt new views so fast as they shall appear to be true views.
