But this movement, or agitation, as it is reproachfully called, is boldly pronounced injurious to the very object desired. Now, without entering into details, which neither time nor the occasion justifies, let me say that this objection belongs to those commonplaces which have been arrayed against every good movement in the world's history, against even knowledge itself, against the abolition of the slave-trade. Perhaps it was not unnatural for the Senator from North Carolina [Mr. BADGER] to press it, even as vehemently as he did; but it sounded less natural, when it came, though in more moderate phrase, from my distinguished friend and colleague from Massachusetts [Mr. EVERETT]. The past furnishes a controlling example by which its true character may be determined. Call to mind, Sir, that the efforts of William Wilberforce encountered this precise objection, and that the condition of the kidnapped slave was then vindicated, in language not unlike that of the Senator from North Carolina, by no less a person than the Duke of Clarence, of the royal family of Great Britain. In what was called his maiden speech, on the 3d of May, 1792 and preserved in the Parliamentary Debates, he said: "The negroes were not treated in the manner which had so much agitated the public mind. He had been an attentive observer of their state, and had no doubt but he could bring forward proofs to convince their Lordships that their state was far from being miserable: on the contrary, that, when the various ranks of society were considered, they were comparatively in a state of humble happiness." And only the next year, this same royal prince, in debate in the House of Lords, asserted that the promoters of the abolition of the slave-trade were "either fanatics or hypocrites," and in one of these classes he ranked Wilberforce. Mark now the end. After years of weary effort, the slave-trade was finally abolished; and at last, in 1833, the early vindicator of this enormity, the maligner of a name hallowed among men, was brought to give his royal assent, as William the Fourth, King of Great Britain, to the immortal Act of Parliament, greater far than any victory of war, by which Slavery was abolished throughout the British dominions. Sir, time and the universal conscience have vindicated the labors of Wilberforce. The movement against American Slavery, protected by the august names of Washington, Franklin, and Jefferson, can calmly await a similar judgment.
