"Torture was necessary to maintain slavery. It was integral to slavery. You cannot have slavery without some torture or the threat of torture; and you cannot have torture without slavery. You cannot imprison a free man for ever unless you have broken him; and you can only forcibly break a man's soul by torturing it out of him. Slavery dehumanizes; torture dehumanizes in exactly the same way. The torture of human beings who have no freedom and no recourse to the courts is slavery."
