"9. Combination of agriculture with manufacturing industries; gradual abolition between town and country, by a more equable distribution of population over the country. "10. Free education for all children in public schools, combination of education with industrial production," _etc._ Though the "Manifesto" was written in 1848, neither Marx, who lived until 1882, nor Engels, who died in 1895, made any alteration in it, on the ground that it had become "a historical document which we have no longer any right to alter."[3] "However much the state of things may have altered during the last twenty-five years, the general principles laid down in this manifesto are, on the whole, as correct to-day as ever."[4] On one very important point, however, they could not refrain from further comment. The revolutionary language in the original draft would be radically mollified if written at the time of the joint preface in 1872. The example of the Paris Commune was disheartening. It demonstrated that "the working class cannot simply lay hold of the ready-made state machinery and wield it for its own purposes."[5] These, then, were the principles of the international movement of which the "Manifesto" was the supreme expression. When labor had revived from its first stupor, after the hard blows it received in the years of revolution, the "Manifesto" was translated into several Continental languages. With the revival of internationalism, it has been translated into every language of the industrial world, and I am told a Japanese and a Turkish edition have been issued. This is a gauge of the spread of international Socialism. In 1862 a number of French workingmen, visiting the International Exhibition in London, were entertained by the Socialist exiles, and the question of reviving an international movement was discussed. Two years later, in St. Martin's Hall, London, workingmen from various countries organized a meeting and selected Mazzini, the Italian patriot, to draw up a constitution. But the South European view of class war was out of accord with the German and French views, and Mazzini's proposals were rejected. Marx then undertook the writing of the address. He succeeded remarkably well in avoiding the giving of offense to the four different elements present, namely, the trade unionists of England, who, being Englishmen, were averse to revolutions; the followers of Proudhon in France, who were then establishing free co-operative societies; the followers of Lassalle in Germany and Louis Blanc in France, who glorified state aid in co-operation; and the less easily satisfied contingent of Mazzini from Spain and Italy.
