I should like you to remember two or three fixed principles which shine through all the history of mankind. The first is that mere bigness is not greatness. There is no dignity, no nobleness, in mere bulk. The true greatness of a nation depends upon the character of its ethical ideal and the energy with which it pursues it. I count it a peculiar good fortune for the American nation that it was conceived in liberty and intelligence and swaddled in order and justice, and that its early years were watched over by men who saw in such an organization the best hopes of the human race. But the baptism of the fathers does not guarantee the consecration of their children; and the republic can be kept true to its ideals only by the devoted efforts of each succeeding generation. Thus is it the privilege of the quiet scholar, who sees and speaks the truth, to shape from his study the policy of nations and the course of history.
