I think the negro is included in the word 'men' used in the Declaration of Independence.

In giving freedom to the slave, we assure freedom to the free.

I believe the Declaration that 'all men are created equal' is the great fundamental principle upon which our free institutions rest.

A house divided against itself cannot stand. I believe this government cannot endure permanently half slave and half free.

Man is really free, the real man cannot but be free.

No chains around my feet, but I'm not free.
