When…you have succeeded in dehumanizing the Negro, when you have put him down and made it forever impossible for him to be but as the beasts of the field; when you have extinguished his soul and placed him where the ray of hope is blown out in darkness like that which broods over the spirits of the damned, are you quite sure that the demon you have roused will not turn and rend you?

speech at Edwardsville, Illinois, 11 September 1858
