And why did the representatives of five great nations come together to destroy the slave trade in Africa, and from every coast come the columns of light to journey toward the heart of the dark continent and rim all Africa around with little towns and villages that glow like lighthouses for civilization? Because one day Westminster Abbey was crowded with the great men of England, in the midst of whom stood two black men who had brought Livingstone's body from the jungles of Africa. There, in the great Abbey, faithful Susi told of the hero who, worn thin as parchment through thirty attacks of the African fever, refused Stanley's overtures, turned back toward Ulala, made his ninth attempt to discover the head-waters of the Nile and search out the secret lairs of the slave-dealers, only to die in the forest, with no white man near, no hand of sister or son to cool his fevered brow or close his glazing eyes. Faithful to the last to that which had been the great work of his life, he wrote these words with dying hand: "All I can add in my solitude is, may heaven's rich blessings come down on every one who would help to heal this open sore of the world!" Why was it that in the ten years after Livingstone's death, Africa made greater advancement than in the previous ten centuries? All the world knows that it was through the vicarious suffering of one of Scotland's noblest heroes. And why is it that Curtis says that there are three American orations that will live in history--Patrick Henry's at Williamsburg, Abraham Lincoln's at Gettysburg and Wendell Philips' at Faneuil Hall? A thousand martyrs to liberty lent eloquence to Henry's lips; the hills of Gettysburg, all billowy with our noble dead, exhaled the memories that anointed Lincoln's lips; while Lovejoy's spirit, newly martyred at Alton, poured over Wendell Phillips' nature the full tides of speech divine. Vicarious suffering explains each of these immortal scenes.
