‘Morality and slavery’ argues that, as much as detachment and dispassion govern standard historical practice, historians cannot escape making moral judgments. Precisely because slavery is a morally charged subject, its history has been especially prone to changing points of view, traceable, for example, in recent histories of the slave trade and the controversy over Olaudah Equiano's birthplace. Various polar extremes – the structural coerciveness of slavery versus the agency of slaves; the persistence of African ethnicities versus rapid creolization; the spread of slavery versus the rapid growth of anti-slavery in the early republic – are evident in historical interpretations, which necessarily involve complicated value judgments and serious moral ramifications. The essay concludes by suggesting that a measure of balance and fairness has been possible in the study of slavery. Through empathy, historians have been able to recover, in part at least, the hopes and fears, dreams and nightmares, notions of right and wrong among both slaves and masters in previous epochs.
