first time systematically set forth in his address (April 12, 1862) "upon the special connection between modern times and the idea of a laboring class," subsequently published under the title, The Workingmen's Programme. This address was the point of departure for the socialist movement in Germany, as the Communist Manifesto of Marx and Engels was that of international socialism. It was indeed largely inspired by the spirit of that revolutionary document. During the two and a half years which followed the publication of this address, Lassalle often set forth his fundamental social philosophy with extraordinary clearness and force, but he never surpassed his opening salutation to the workingmen of Germany. It has been read by hundreds of thousands. It was his masterpiece.
The Workingmen's Programme attracted the immediate attention of the Prussian government. The police took offence at the tone of the address and brought against its author a charge of criminal incitement of the poor to hatred and contempt of the rich. On January 16, 1863, Lassalle appeared in court and defended himself against this charge in an almost equally celebrated address, published under the title, Science and the Workingmen. Here Lassalle speaks in a different but no less brilliant vein. From that time forth Lassalle's appearances before audiences of workingmen quite generally led to corresponding appearances before audiences of judges. If one court set him free, he was liable to be haled before another court for defamation of the prosecuting attorney in the court of first resort. But the prisoner's dock served as well as the orator's platform for the purposes of his agitation.
The Workingmen's Programme attracted less immediate attention from the workingmen themselves. But among the few whose attention was attracted was a group of Leipzig labor leaders who invited Lassalle to advise them more fully concerning his plans for the formation of an independent labor party. Lassalle's reply to this invitation was the Open Letter to the Committee for the Calling
