What _have_ they meant? They have meant peace and union and vigor, and the maturity and might of a great nation. How wholesome and healing the peace has been! We have found one another again as brothers and comrades in arms, enemies no longer, generous friends rather, our battles long past, the quarrel forgotten--except that we shall not forget the splendid valor, the manly devotion of the men then arrayed against one another, now grasping hands and smiling into each other's eyes. How complete the union has become and how dear to all of us, how unquestioned, how benign and majestic, as State after State has been added to this our great family of free men! How handsome the vigor, the maturity, the might of the great Nation we love with undivided hearts; how full of large and confident promise that a life will be wrought out that will crown its strength with gracious justice and with a happy welfare that will touch all alike with deep contentment! We are debtors to those fifty crowded years; they have made us heirs to a mighty heritage. But do we deem the Nation complete and finished? These venerable men crowding here to this famous field have set us a great example of devotion and utter sacrifice. They were willing to die that the people might live. But their task is done. Their day is turned into evening. They look to us to perfect what they established. Their work is handed on to us, to be done in another way, but not in another spirit. Our day is not over; it is upon us in full tide. Have affairs paused? Does the Nation stand still? Is what the fifty years have wrought since those days of battle finished, rounded out, and completed? Here is a great people, great with every force that has ever beaten in the lifeblood of mankind. And it is secure. There is no one within its borders, there is no power among the nations of the earth, to make it afraid. But has it yet squared itself with its own great standards set up at its birth, when it made that first noble, naive appeal to the moral judgment of mankind to take notice that a government had now at last been established which was to serve men, not masters? It is secure in everything except the satisfaction that its life is right, adjusted to the uttermost to the standards of righteousness and humanity. The days of sacrifice and cleansing are not closed. We have harder things to do than were done in the heroic days of war, because harder to see clearly, requiring more vision, more calm balance of judgment, a more candid searching of the very springs of right.
