From the day of its birth, the anomaly of slavery plagued a nation which asserted the equality of all men, and sought to derive powers of government from the consent of the governed. Within sound of the voices of those who said this lived more than half a million black slaves, forming nearly one-fifth of the population of a new nation.

Negroes could be sold - actually sold as we sell cattle, with no reference to calves or bulls or recognition of family. It was a nasty business. The white South was properly ashamed of it and continually belittled and almost denied it. But it was a stark and bitter fact.

The slavery of Negroes in the South was not usually a deliberately cruel and oppressive system. It did not mean systematic starvation or murder.
