3. Western Europe received all the wisdom and experience of the ancient world, and labored well at the grand problem, though she did not completely solve it. She, however, made an immense advance toward it, and her children, rich in her experience, instructed at once by her success and her mistakes, and aided always by her wisdom, found (let us hope) in America the goal of their noblest aspirations. Thus we find the spirit of progress traversing the whole course of human history, constantly advancing through all the confusion of rising and falling states, of battle, siege and slaughter, of victory and defeat; through the varying fortunes and ultimate extinction of monarchy, republic and empire; through barbaric irruption and desolation, feudal isolation, spiritual supremacy, the heroic rush and conflict of the Cross and the Crescent; amid the busy hum of industry, through the marts of trade and behind the gliding keels of commerce; through the bloody conflicts of commons, nobles, kings and kaisers to New and Free America. There the Englishman, the German, the Frenchman, the Italian, the Scandinavian, the Asiatic and the African all meet as equals. There they are free to speak, to think, and to act. They bring their common contributions of character, energy and activity to the support and enlargement of a common country, and the spread of its influence and enlightenment through all the lands of their origin. As America is the common ground on which all the currents and ideas of all the civilizations meet, so also it is the point from which return currents, hastened by lightning and by steam, seek again every quarter of the earth with kindly greetings, to renew the relations broken in the original separation of the races, and to cement, by exchanges mutually profitable, a new and better unity of mankind. As the heart in the human body receives the current of blood from all parts of the system, and, having revitalized it, returns it with fresh elements of strength, so America adopts the children of all lands only to return a manhood ennobled by a sense of its own dignity through the practice of a system of self-government which improves the condition and promotes the interest of each while it produces harm to none.
