"The system was psychological and physical at the same time. The slaves were taught discipline, were impressed again and again with the idea of their own inferiority to "know their place," to see blackness as a sign of subordination, to be awed by the power of the master, to merge their interest with the master's, destroying their own individual needs. To accomplish this there was the discipline of hard labor, the breakup of the slave family, the lulling effects of religion (which sometimes led to "great mischief," as one slaveholder reported), the creation of disunity among slaves by separating them into field slaves and more privileged house slaves, and finally the power of law and the immediate power of the overseer to invoke whipping, burning, mutilation, and death. Dismemberment was provided for in the Virginia Code of 1705. Maryland passed a law in 1723 providing for cutting off the ears of blacks who struck whites, and that for certain serious crimes, slaves should be hanged and the body quartered and exposed."
