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

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

Science and democracy are the right and left hands of what I'll refer to as the move from the realm of necessity to the realm of freedom.

Whenever I hear anyone arguing for slavery I feel a strong impulse to see it tried on him personally.

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

God gave man a mouth to receive bread, hands to feed it, and his hand has a right to carry bread to his mouth without controversy.
