The slavery in the United States was a paradox because it contradicted the American ideal of freedom C. Slavery is one the black chapters in mankind history. It shows barbarian, immorality and misunderstanding.
And yet the article spends surprisingly little time on the ideals of the Declaration of Independence or Virginiaâs slave society, and neither does American Slavery, American Freedom. Itâs an irony that Edmund S. Morgan (1916â2013), the articleâs author, would have appreciated (call it the âthe âParadoxâ paradoxâ): how an unintended argument became his most enduring legacy. âSlavery and Freedomâ began life as Morganâs presidential address to the Organization of American Historians in April 1972.
