The clash between Wagner and his critics was a matter of poetry and dramatic music. It was not vital to the human race. The cause of Marx is one that is only now beginning to be understood and recognized by millions of men and women in all the countries of the earth. In his lifetime he issued a manifesto that has become a classic among economists. He organized the great International Association of Workmen, which set all Europe in a blaze and extended even to America. His great book, "Capital"--Das Kapital--which was not completed until the last years of his life, is read to-day by thousands as an almost sacred work. Like Wagner and his Minna, the wife of Marx's youth clung to him through his utmost vicissitudes, denying herself the necessities of life so that he might not starve. In London, where he spent his latest days, he was secure from danger, yet still a sort of persecution seemed to follow him. For some time, nothing that he wrote could find a printer. Wherever he went, people looked at him askance. He and his six children lived upon the sum of five dollars a week, which was paid him by the New York Tribune, through the influence of the late Charles A. Dana. When his last child was born, and the mother's life was in serious danger, Marx complained that there was no cradle for the baby, and a little later that there was no coffin for its burial. Marx had ceased to believe in marriage, despised the church, and cared nothing for government. Yet, unlike Wagner, he was true to the woman who had given up so much for him. He never sank to an artistic degeneracy. Though he rejected creeds, he was nevertheless a man of genuine religious feeling. Though he believed all present government to be an evil, he hoped to make it better, or rather he hoped to substitute for it a system by which all men might get an equal share of what it is right and just for them to have. Such was Marx, and thus he lived and died. His wife, who had long been cut off from her relatives, died about a year before him. When she was buried, he stumbled and fell into her grave, and from that time until his own death he had no further interest in life. He had been faithful to a woman and to a cause. That cause was so tremendous as to overwhelm him. In sixty years only the first great stirrings of it could be felt. Its teachings may end in nothing, but only a century or more of effort and of earnest striving can make it plain whether Karl Marx was a world-mover or a martyr to a cause that was destined to be lost.
