The fact that the provision on this subject was adopted unanimously, while showing the little importance attached to it in the shape it finally assumed, testifies also that it could not have been regarded as a source of national power for Slavery. It will be remembered that among the members of the Convention were Gouverneur Morris, who had said that he "NEVER would concur in upholding domestic Slavery,"--Elbridge Gerry, who thought we "ought to be careful NOT to give any sanction to it,"--Roger Sherman, who "was OPPOSED to a tax on slaves imported, because it implied they were property,"--James Madison, who "thought it WRONG to admit in the Constitution the idea that there could be property in men,"--and Benjamin Franklin, who likened American slaveholders to Algerine corsairs. In the face of these unequivocal judgments, it is absurd to suppose that these eminent citizens consented unanimously to any provision by which the National Government, the creature of their hands, dedicated to freedom, could become the most offensive agent of Slavery.
Thus much for the evidence from the history of the Convention. But the true principles of our political system are in harmony with this conclusion of history; and here let me say a word of State rights.
It was the purpose of our fathers to create a National Government, and to endow it with adequate powers. They had known the perils of imbecility, discord, and confusion, protracted through the uncertain days of the Confederation, and they desired a government which should be a true bond of union and an efficient organ of national interests at home and abroad. But while fashioning this agency, they fully recognized the governments of the States. To the nation were delegated high powers, essential to the national interests, but specific in character and limited in number. To the States and to the people were reserved the powers, general in character and unlimited in number, not delegated to the nation or prohibited to the States.
The integrity of our political system depends upon harmony in the operations of the Nation and of the States. While the nation within its wide orbit is supreme, the States move with equal supremacy in their own. But, from the necessity of the case, the supremacy of each in its proper place excludes the other. The Nation cannot exercise rights reserved to the States, nor can the States interfere with the powers of the nation. Any such action on either side is a usurpation. These principles were distinctly declared by Mr. Jefferson in 1798, in words often adopted since, and which must find acceptance from all parties.
