We have written rather for the living than the dead. As one of that proscribed and hunted band of Abolitionists, whose rights were so bravely defended by William Leggett, we should, indeed, be wanting in ordinary gratitude not to do honor to his memory; but we have been actuated at the present time mainly by a hope that the character, the lineaments of which we have so imperfectly sketched, may awaken a generous emulation in the hearts of the young democracy of our country. Democracy such as William Leggett believed and practised, democracy in its full and all- comprehensive significance, is destined to be the settled political faith of this republic. Because the despotism of slavery has usurped its name, and offered the strange incense of human tears and blood on its profaned altars, shall we, therefore, abandon the only political faith which coincides with the Gospel of Jesus, and meets the aspirations and wants of humanity? No. The duty of the present generation in the United States is to reduce this faith to practice, to make the beautiful ideal a fact. "Every American," says Leggett, "who in any way countenances slavery is derelict to his duty, as a Christian, a patriot, a man; and every one does countenance and authorize it who suffers any opportunity of expressing his deep abhorrence of its manifold abominations to pass unimproved." The whole world has an interest in this matter. The influence of our democratic despotism is exerted against the liberties of Europe. Political reformers in the Old World, who have testified to their love of freedom by serious sacrifices, hold but one language on this point. They tell us that American slavery furnishes kings and aristocracies with their most potent arguments; that it is a perpetual drag on the wheel of political progress. We have before us, at this time, a letter from Seidensticker, one of the leaders of the patriotic movement in behalf of German liberty in 1831. It was written from the prison of Celle, where he had been confined for eight years. The writer expresses his indignant astonishment at the speeches of John C. Calhoun, and others in Congress, on the slavery question, and deplores the disastrous influence of our great inconsistency upon the cause of freedom throughout the world,--an influence which paralyzes the hands of the patriotic reformer, while it strengthens those of his oppressor, and deepens around the living martyrs and confessors of European democracy the cold shadow of their prisons.
