It is to the training of the genuine man that the universities of the world are devoted. They call for the higher sacrifice, the sacrifice of those who have powers not needed in the common struggle of life, and who have, therefore, something over and beyond this struggle to give to their fellows. Large or small, whatever the gift may be, the world needs it all, and to every good gift the world will respond a thousand-fold. Strength begets strength, and wisdom leads to wisdom. "There is always room for the man of force, and he makes room for many." It is the strong, wise, and good of the past who have made our lives possible. It is the great human men, the "men in the natural order," that have made it possible for "the plain, common men," that make up civilization, to live, rather than merely to vegetate. We hear those among us sometimes who complain of the shortness of life, the smallness of truth, the limited stage on which man is forced to act. But the men who thus complain are not men who have filled this little stage with their action. The man who has learned to serve the Lord never complains that his Master does not give him enough to do. The man who helps his fellow-men does not stand about with idle hands to find men worthy of his assistance. He who leads a worthy life never vexes himself with the question as to whether life is worth living. We know that all our powers are products of the needs and duties of our ancestors. Wisdom too great to be translated into action is an absurdity. For wisdom is only knowing what it is best to do next. Virtue is only doing it. Virtue and happiness have never been far apart from each other. To know and to do is the essence of the highest service. Those the world has a right to honor are those who found enough in the world to do. The fields are always white to their harvest. Alexander the Great had conquered his neighbors in Greece and Asia Minor, the only world he knew. Then he sighed for more worlds to conquer. But other worlds he knew nothing of lay all about him. The secrets of the rocks he had never suspected. Steam, electricity, the growth of trees, the fall of snow,--all these were mysteries to him. The only conquest he knew, the subjection of men's bodies, went but a little way. All the men who in his lifetime knew the name of Alexander the Great could find encampment on the Palo Alto farm. The great world of men in his day was beyond his knowledge. His world was a very small one, and of this he had seen but a little corner. For the need of more worlds to conquer is no badge of strength. It is the stamp of ignorance. It is the cry only of him who knows that the great earth about him still stands unconquered. No Lincoln ever sighed for more nations to save; no Luther for more churches to purify; no Darwin that nature had not more hidden secrets which he might follow to their depths; no Agassiz that the thoughts of God were all exhausted before he was born.
