So much for our duties, each to himself and each to his neighbor, within the limits of our own country. But our country, as it strides forward with ever-increasing rapidity to a foremost place among the world powers, must necessarily find, more and more, that it has world duties also. There are excellent people who believe that we can shirk these duties and yet retain our self-respect; but these good people are in error. Other good people seek to deter us from treading the path of hard but lofty duty by bidding us remember that all nations that have achieved greatness, that have expanded and played their part as world powers, have in the end passed away. So they have; and so have all others. The weak and the stationary have vanished as surely as, and more rapidly than, those whose citizens felt within them the lift that impels generous souls to great and noble effort. This is only another way of stating the universal law of death, which is itself part of the universal law of life. The man who works, the man who does great deeds, in the end dies as surely as the veriest idler who cumbers the earth’s surface; but he leaves behind him the great fact that he has done his work well. So it is with nations. While the nation that has dared to be great, that has had the will and the power to change the destiny of the ages, in the end must die, yet no less surely the nation that has played the part of the weakling must also die; and whereas the nation that has done nothing leaves nothing behind it, the nation that has done a great work really continues, though in changed form, to live for evermore. The Roman has passed away exactly as all the nations of antiquity which did not expand when he expanded have passed away; but their very memory has vanished, while he himself is still a living force throughout the wide world in our entire civilization of to-day, and will so continue through countless generations, through untold ages.
