The nineteenth century was the age of Power Discovered; mechanical inventions, the concentration of industry, the extension of the factory system, new means of transportation destroyed the last vestige of the feudal world and left the democratic ideal triumphant but unfulfilled: a new century dawns,—the age of Power Humanized. The industrial world in which we live, with all its peculiar characteristics, has been built upon the ruins of the feudal order, and in due time will give place to a newer and better civilization. Radicals of to-day see visions of to-morrow; reformers fired by the visions seek to make them real; while conservatives, clinging to the traditions of a dead past, strive to stay the inevitable progress of mankind. Truth never changes, but the knowledge of truth grows deeper with each age; no political institution, no social institution is sacred unless it is founded upon some eternal truth, and all human institutions must change with the increasing knowledge of mankind. Everywhere in the Western world the condition of the laboring population is vastly better to-day than when, a century and a half ago, the factory was established; vastly better than when, sixty years ago, the governments of Europe trembled before a working-class revolt,—when British Chartism triumphed in reform; when Karl Marx, exiled from Prussia, called upon the workingmen of the world to unite; when Mazzini, another exile in London, preached to the toilers of Italy the gospel of God and humanity, of progress through education. But the evolution is incomplete, and the discontent of the laboring population still remains a vital force in the upward progress of mankind.
