"My argument against the dissolution of the American Union is this. It would place the slave system more exclusively under the control of the slave - holding states, and withdraw it from the power in the northern states which is opposed to slavery. Slavery is essentially barbarous in its character. It, above all things else, dreads the presence of an advanced civilization. It flourishes best where it meets no reproving frowns, and hears no condemning voices. While in the Union it will meet with both. Its hope of life, in the last resort, is to get out of the Union. I am, therefore, for drawing the bond of the Union more completely under the power of the free states. What they most dread, that I most desire. I have much confidence in the instincts of the slaveholders. They see that the Constitution will afford slavery no protection when it shall cease to be administered by slaveholders. They see, moreover, that if there is once a will in the people of America to abolish slavery, this is no word, no syllable in the Constitution to forbid that result. They see that the Constitution has not saved slavery in Rhode Island, in Connecticut, in New York, or Pennsylvania; that the Free States have only added three to their original number. There were twelve Slave States at the beginning of the Government: there are fifteen now."
