We believe that the spreading out and perpetuity of the institution of slavery impairs the general welfare. We believe - nay, we know, that that is the only thing that has ever threatened the perpetuity of the Union itself.
I say now, however, as I have all the while said, that on the territorial question - that is, the question of extending slavery under the national auspices, - I am inflexible. I am for no compromise which assists or permits the extension of the institution on soil owned by the nation.
Slavery is wrong. If Slavery is right, all words, acts, laws, and Constitutions against it, are themselves wrong, and should be silenced, and swept away.
