Slaveholders kept slaves illiterate because reading awakens awareness of one's condition and the desire to escape it — education and bondage are incompatible. Learning to read makes a person 'unfit' to be a slave by giving them the conceptual tools to recognize and resent their unfreedom.
Slaveholders who converted to Christianity became crueler, not kinder, because religion supplied moral justification and divine sanction for their brutality. Piety and savagery coexisted because the religion of the slaveholding South was structurally distinct from and opposed to the religion of Christ.
