We have indeed been authoritatively told in Congress and elsewhere that our brethren of the South and West will brook no further agitation of the subject of slavery. What then! shall we heed the unrighteous prohibition? No; by our duty as Christians, as politicians, by our duty to ourselves, to our neighbor, and to God, we are called upon to agitate this subject; to give slavery no resting-place under the hallowed aegis of a government of freedom; to tear it root and branch, with all its fruits of abomination, at least from the soil of the national domain. The slave-holder may mock us; the representatives of property, merchandise, vendible commodities, may threaten us; still our duty is imperative; the spirit of the Constitution should be maintained within the exclusive jurisdiction of the government. If we cannot "provide for the general welfare," if we cannot "guarantee to each of the states a republican form of government," let us at least no longer legislate for a free nation within view of the falling whip, and within hearing of the execrations of the task-master and the prayer of his slave! I deny the right of the slave-holder to impose silence on his brother of the North in reference to slavery. What! compelled to maintain the system, to keep up the standing army which protects it, and yet be denied the poor privilege of remonstrance! Ready, at the summons of the master to put down the insurrections of his slaves, the outbreaking of that revenge which is now, and has been, in all nations, and all times, the inevitable consequence of oppression and wrong, and yet like automata to act but not speak! Are we to be denied even the right of a slave, the right to murmur? I am not unaware that my remarks may be regarded by many as dangerous and exceptionable; that I may be regarded as a fanatic for quoting the language of eternal truth, and denounced as an incendiary for maintaining, in the spirit as well as the letter, the doctrines of American Independence. But if such are the consequences of a simple performance of duty, I shall not regard them. If my feeble appeal but reaches the hearts of any who are now slumbering in iniquity; if it shall have power given it to shake down one stone from that foul temple where the blood of human victims is offered to the Moloch of slavery; if under Providence it can break one fetter from off the image of God, and enable one suffering African "To feel The weight of human misery less, and glide Ungroaning to the tomb," I shall not have written in vain; my conscience will be satisfied.
