Our relations with the other Powers of the world are important; but still more important are our relations among ourselves. Such growth in wealth, in population, and in power as this Nation has seen during the century and a quarter of its national life is inevitably accompanied by a like growth in the problems which are ever before every nation that rises to greatness. Power invariably means both responsibility and danger. Our forefathers faced certain perils which we have outgrown. We now face other perils the very existence of which it was impossible that they should foresee. Modern life is both complex and intense, and the tremendous changes wrought by the extraordinary industrial development of the last half century are felt in every fibre of our social and political being. Never before have men tried so vast and formidable an experiment as that of administering the affairs of a continent under the forms of a democratic republic. The conditions which have told for our marvelous material well-being, which have developed to a very high degree our energy, self-reliance, and individual initiative, have also brought the care and anxiety inseparable from the accumulation of great wealth in industrial centres. Upon the success of our experiment much depends; not only as regards our own welfare, but as regards the welfare of mankind. If we fail, the cause of free self-government throughout the world will rock to its foundations; and therefore our responsibility is heavy, to ourselves, to the world as it is to-day, and to the generations yet unborn. There is no good reason why we should fear the future, but there is every reason why we should face it seriously, neither hiding from ourselves the gravity of the problems before us nor fearing to approach these problems with the unbending, unflinching purpose to solve them aright.
