With argument as impetuous, and logic as inexorable, he disposes of Douglas's plea of popular sovereignty:
Here, or at Washington, I would not trouble myself with the oyster laws of Virginia, or the cranberry laws of Indiana. The doctrine of self-government is right-absolutely and eternally right-but it has no just application as here attempted. Or perhaps I should rather say, that whether it has such application depends upon whether a negro is not or is a man. If he is not a man, in that case, he who is a man may, as a matter of self-government, do just what he pleases with him. But if the negro is a man, is it not to that extent a total destruction of self-government to say that he too shall not govern himself? When the white man governs himself, that is self-government; but when he governs himself and also governs another man, that is more than self-government — that is despotism. ... I particularly object to the new position which the avowed principle of this Nebraska law gives to slavery in the body politic. I object to it because it assumes that there can be moral right in the enslaving of one man by another. I object to it as a dangerous dalliance for a free people — a sad evidence that, feeling prosperity, we forget right; that liberty, as a principle, we have ceased to revere ... Little by little, but steadily as man's march to the grave, we have been giving up the old for the new faith. Near eighty years ago we began by declaring that all men are created equal; but now, from that beginning, we have run down to the other declaration, that for some men to enslave others is a ‘sacred right of self-government.’ These principles cannot stand together. They are as opposite as God and Mammon.
