If you follow Mr. Douglas in his various speeches, you cannot fail to be shocked by the heartlessness of his language. Never in history has any public man insulted human nature so boldly. At the North he announces himself as “always for the white man against the nigger,” but at the South he is “for the nigger against the alligator.” It was natural that such a man, who thus mocked at a portion of God’s creation made in the Divine image, should say, “Vote Slavery up or vote it down,”--as if the idea of voting it up were not impious and never to be endured. Beyond all doubt, no majority can be permitted to vote that fellow-men shall be bought and sold like cattle. The pretension is preposterous, aggravated by knowledge on his part that under his device the settlers could only vote Slavery up, and that they were not allowed to vote it down. But this speech attests a brazen insensibility to Human Rights. Not so spoke the Fathers of the Republic, who would not let us miss an opportunity to vote Slavery down. Not so spoke Washington, who declared that to the abolition of Slavery “his suffrage should never be wanting.” Such is the whole political philosophy of this Presidential candidate. A man thus indifferent to the rights of a whole race is naturally indifferent to other things which make for justice and peace. Again he cries out, that the Slavery agitation is in the way of public business, and that it must be removed from Congress. But who has thrust it there so incessantly as himself? Nay, who so largely as himself has been the occasion of its appearance? His complaint illustrates anew the old fable. It was the wolf above that troubled the waters, and not the lamb below. It is the Slave Propagandists--among whom the champion of Popular Sovereignty must find a place--who, from the Missouri Compromise in 1820, through all the different stages of discussion, down to the shutting out of Kansas as a Free State at the recent session, have rendered it impossible to avoid the exciting subject. By dishonest, audacious theories of Slavery, both morally and constitutionally, they have aroused a natural opposition, and put all who truly love their country on the defensive. Yes, it is in defence of the Constitution perverted, of reason insulted, and of humanity disowned, that we are obliged to speak out. * * * * *
