"A HOUSE DIVIDED CANNOT STAND."
This often-quoted passage was uttered in June, 1857, at Springfield, Illinois, during Lincoln's congressional campaign:
"A house divided against itself cannot stand. I believe that this government cannot endure permanently, half-slave and half-free. I do not expect this house to fall: I do not expect the Union to be dissolved. But I do expect it will cease to be divided. It will become one thing or the other."
