In this spirit, and with this encouragement, we must labor for that grand and final object, watchword of all ages, the Unity of the Human Family. Not in benevolence, but in selfishness, has Unity been sought in times past,—not to promote the happiness of all, but to establish the dominion of one. It was the mad lust of power which carried Alexander from conquest to conquest, till he boasted that the whole world was one empire, with the Macedonian phalanx as citadel. The same passion animated Rome, till, at last, while Christ lay in a manger, this single city swayed a broader empire than that of Alexander. The Gospel, in its simple narrative, says, "And it came to pass in those days that there went out a decree from Cæsar Augustus that all the world should be taxed." History recalls the exile of Ovid, who, falling under the displeasure of the same emperor, was condemned to close his life in melancholy longings for Rome, far away in Pontus, on the Euxine Sea. With singular significance, these two contemporaneous incidents reveal the universality of Roman dominion, stretching from Britain to Parthia. The mighty empire crumbled, to be reconstructed for a brief moment, in part by Charlemagne, in part by Tamerlane. In our own age, Napoleon made a last effort for Unity founded on Force. And now, from his utterances at St. Helena, the expressed wisdom of his unparalleled experience, comes the remarkable confession, worthy of constant memory: "The more I study the world, the more am I convinced of the inability of brute force to create anything durable." From the sepulchre of Napoleon, now sleeping on the banks of the Seine, surrounded by the trophies of battle, nay, more, from the sepulchres of all these departed empires, may be heard the words, "They that take the sword shall perish by the sword."
Unity is the longing and tendency of Humanity: not the enforced Unity of military power; not the Unity of might triumphant over right; not the Unity of Inequality; not the Unity which occupied the soul of Dante, when, in his treatise De Monarchia, the earliest political work of modern times, he strove to show that all the world belonged to a single ruler, the successor of the Roman Emperor: not these; but the voluntary Unity of nations in fraternal labor; the Unity promised, when it was said, "There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female, for ye are all one in Christ Jesus"; the Unity which has filled the delighted vision of good men, prophets, sages, and poets, in times past; the Unity which, in our own age, prompted Béranger, the incomparable lyric of France, in an immortal ode, to salute the Holy Alliance of the Peoples,[318] summoning them in all lands, and by whatever names they may be called, French, English, Belgian, German, Russian, to give each other the hand, that the useless thunderbolts of War may all be quenched, and Peace sow the earth with gold, with flowers, and with corn; the Unity which prompted an early American diplomatist and poet to anticipate the time when nations shall meet in Congress,—
"To give each realm its limit and its laws,
Bid the last breath of dire contention cease,
And bind all regions in the leagues of Peace;
Bid one great empire, with extensive sway,
Spread with the sun, and bound the walks of day,
One centred system, one all-ruling soul,
Live through the parts, and regulate the whole";[319]
