The evolution of ideas is that which now rules the world; and if people do not always comprehend this fact it is because the selfish and personal prejudices, passions, and interests disturb and impair their judgment. In modern progress, the régime of privilege and of force can no longer create rights nor lend security for the future or the aggrandizement of nations; and nowadays those individuals do not render a service to their native land who, while they sacrifice permanent interests, think they can calculate the meridian of their country by the artificial reflections of a moment, transitory and perishable. The régime of force or of armed peace consumes the vital forces and the resources of nations; and then from the abyss of inequality, of affliction, and danger produced, bursts forth once more the social and political problem demanding, with threats, the reform of the evil, and laying down the maxim that only the ideal of justice, of liberty, and of human solidarity can possibly stand forth, firm and unshaken, amidst the ruins in which the wild ideas of greatness held by the military powers of the world will remain buried forever. It is not by means of a régime of force, but by that of liberty, peace, and labor, that the United States of America has been enabled to form a marvelous abode of vitality and human progress; and its government, with a perfect insight into the greatness of that country and of its destiny, today addresses the present and the future of our world, and with special interest explains to America the only paths that will lead the nations to the attainment of tranquillity and well-being. Once that existence is obtained, you have said, Mr. Root, that it is necessary to live and advance worthily and honorably,--and that this object cannot be attained by a régime of domestic oppression and of privilege, nor by the external one of isolation or of war, but by that of liberty, order, justice, economical progress, moral improvement, intellectual advance, respect for the rights of others, and a feeling of human solidarity. You have clearly stated: No nation can live unto itself alone and continue to live. Each nation's growth is a part of the development of the race.... A people whose minds are not open to the lessons of the world's progress, whose spirits are not stirred by the aspirations and achievements of humanity, struggling the world over for liberty and justice, must be left behind by civilization in its steady and beneficent advance. In the life of nations there must always prevail an ideal and a harmony of right, of liberty, of peace, and fraternity, although this can only be obtained by persevering efforts, by sacrifices, and by a long and distressing march. It is necessary to "labor more for the future than for the present" and unite together all the nations engaged in the same great task, inspired by a like ideal and professing similar principles.
