Context: But one may ask, how is it that slavery, or any other form of invidious discrimination, has played so great a role in American history? How could a nation, dedicated at its birth to the proposition that all men are created equal, have tolerated slavery and its effects so long? If we look to the long history of mankind, however, we will ask a different question. Slavery was lawful in every one of the original thirteen states. There was accordingly nothing remarkable in the fact that slavery was not abolished immediately on independence. What is remarkable is that a slave-owning nation would declare that all men are created equal, and thereby make the abolition of slavery a moral and political necessity. To accomplish that task would not be easy. We need to see the dimensions of that task to appreciate its difficulty.
