The problem of the twentieth century is the problem of the color-line — the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War. – W. E. B. Du Bois
Oh, East is East, and West is West, and never the twain shall meet,
Till Earth and Sky stand presently at Gods great Judgment Seat;
But there is neither East nor West, Border, nor Breed, nor Birth,
When two strong men stand face to face,
tho they come from the ends of the earth! – Rudyard Kipling
