And, if the labor movement has arisen in response to actual material needs, it is now a very great and material actuality. The workingmen of the world are, as we have seen, uniting at a pace so rapid as to be almost unbelievable. There are to-day not only great national organizations of labor in nearly every country, but these national movements are bound closely together into one unified international power. The great world-wide movement of labor, which Marx and Engels prophesied would come, is now here. And, if they were living to-day, they could not but be astonished at the real and mighty manifestation of their early dreams. To be sure, Engels lived long enough to be jubilant over the massing of labor's forces, but Marx saw little of it, and even the German socialists, who started out so brilliantly, were at the time of his death fighting desperately for existence under the anti-socialist law. Indeed, in 1883, the year of his death, the labor movement was still torn by quarrels and dissensions over problems of tactics, and in America, France, and Austria the terrorists were more active than at any time in their history. It was still a question whether the German movement could survive, while in the other countries the socialists were still little more than sects. That was just thirty years ago, while to-day, as we have seen, over ten millions of workingmen, scattered throughout the entire world, fight every one of their battles on the lines laid down by Marx. The tactics and principles he outlined are now theirs. The unity of the workers he pleaded for is rapidly being achieved throughout the entire world, and everywhere these armies are marching toward the goal made clear by his life and labor. "Although I have seen him to-night," writes Engels to Liebknecht, March 14, 1883, "stretched out on his bed, the face rigid in death, I cannot grasp the thought that this genius should have ceased to fertilize with his powerful thoughts the proletarian movement of both worlds. Whatever we all are, we are through him; and whatever the movement of to-day is, it is through his theoretical and practical work; without him we should still be stuck in the mire of confusion."[2]
