The system of slavery is necessarily cruel. The lust of dominion inevitably produces hardness of heart, because the state of mind which craves unlimited power, such as slavery confers, involves a desire to use that power, and although I know there are exceptions to the exercise of barbarity on the bodies of slaves, I maintain that there can be no exceptions to the exercise of the most soul-withering cruelty on the minds of the enslaved. All around is the mighty ruin of intellect, the appalling spectacle of the down-trodden image of God.
Sarah M. Grimké, from An Epistle to the Clergy of the Southern States, New-York, 12th Mo. 1836.
