"And when ... you have succeeded in dehumanizing the negro; when you have put him down and made it impossible for him to be but as the beasts of the field; when you have extinguished his soul in this world and placed him where the ray of hope is blown out as in the darkness of the damned, are you quite sure that the demon you have roused will not turn and rend you? What constitutes the bulwark of our own liberty and independence? It is not our frowning battlements, our bristling sea coasts, our army and our navy. These are not our reliance against tyranny. All of those may be turned against us without making us weaker for the struggle.
Our reliance is in the love of liberty which God has planted in us. Our defence is in the spirit which prizes liberty as the heritage of all men, in all lands everywhere. Destroy this spirit and you have planted the seeds of despotism at your own doors. Familiarize yourselves with the chains of bondage and you prepare your own limbs to wear them. Accustomed to trample on the rights of others, you have lost the genius of your own independence and become the fit subjects of the first cunning tyrant who rises among you." -- Abraham Lincoln September 13, 1858
