Lincoln's House Divided Speech. ... A house divided against itself cannot stand. I believe this government cannot endure, permanently, half slave and half free. I do not expect the Union to be dissolved — I do not expect the house to fall — but I do expect it will cease to be divided.
It is incompatible because having your own opnion seperate from other's beliefs is as Lincoln would put it "divided". To fit Lincoln's description, it would be fit for everyone to have the same opinions, so they aren't divided.
