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 will become all one thing, or all the other. Either the opponents of slavery will arrest the further spread of it$,$ and place it where the public mind shall rest in the belief that it is in the course of ultimate extinction; or its advocates will push it forward till it shall become alike lawful in all the states, old as well as new, North as well as South.
