But it is immaterial whether you legislate for Missouri as a State or not. The effect of your legislation is to bring it into the Union with a portion of its sovereignty taken away.
But it is a State which you are to admit. What is a State in the sense of the Constitution? It is not a State in the general—but a State as you find it in the Constitution. A State, generally, is a body politic or independent political society of men. But the State which you are to admit must be more or less than this political entity. What must it be? Ask the constitution. It shows what it means by a State by reference to the parties to it. It must be such a State as Massachusetts, Virginia, and the other members of the American confederacy—a State with full sovereignty except as the constitution restricts it.
In a word, the whole amount of the argument on the other side is, that you may refuse to admit a new State, and that therefore if you admit, you may prescribe the terms.
The answer to that argument is—that even if you can refuse, you can prescribe no terms which are inconsistent with the act you are to do. You can prescribe no conditions which, if carried into effect, would make the new State less a sovereign State than, under the Union as it stands, it would be. You can prescribe no terms which will make the compact of Union between it and the original States essentially different from that compact among the original States. You may admit, or refuse to admit: but if you admit, you must admit a State in the sense of the Constitution—a State with all such sovereignty as belongs to the original parties: and it must be into this Union that you are to admit it, not into a Union of your own dictating, formed out of the existing Union by qualifications and new compacts, altering its character and effect, and making it fall short of its protecting energy in reference to the new State, whilst it acquires an energy of another sort—the energy of restraint and destruction.
One of the most signal errors with which the argument on the other side has abounded, is this of considering the proposed restriction as if levelled at the introduction or establishment of slavery. And hence the vehement declamation, which, among other things, has informed us that slavery originated in fraud or violence.
The truth is, that the restriction has no relation, real or pretended, to the right of making slaves of those who are free, or of introducing slavery where it does not already exist. It applies to those who are admitted to be already slaves, and who (with their posterity) would continue to be slaves if they should remain where they are at present; and to a place where slavery already exists by the local law. Their civil condition will not be altered by their removal from Virginia, or Carolina, to Missouri. They will not be more slaves than they now are. Their abode, indeed, will be different, but their bondage the same. Their numbers may possibly be augmented by the diffusion, and I think they will. But this can only happen because their hardships will be mitigated, and their comforts increased. The checks to population, which exist in the older States, will be diminished. The restriction, therefore does not prevent the establishment of slavery, either with reference to persons or place; but simply inhibits the removal from place to place (the law in each being the same) of a slave, or make his emancipation the consequence of that removal. It acts professedly merely on slavery as it exists, and thus acting restrains its present lawful effects. That slavery, like many other human institutions, originated in fraud or violence, may be conceded: but, however it originated, it is established among us, and no man seeks a further establishment of it by new importations of freemen to be converted into slaves. On the contrary, all are anxious to mitigate its evils, by all the means within the reach of the appropriate authority, the domestic legislatures of the different States.
Of the declaration of our independence, which has also been quoted in support of the perilous doctrines now urged upon us, I need not now speak at large. I have shown on a former occasion how idle it is to rely upon that instrument for such a purpose, and I will not fatigue you by mere repetition. The self-evident truths announced in the Declaration of Independence are not truths at all, if taken literally; and the practical conclusions contained in the same passage of that declaration prove that they were never designed to be so received.
