Paradox of democracy

Edmund Morgan's "American paradox" refers to the contradiction between the principles of freedom and equality espoused in American society and the existence of slavery in the country's early history. The paradox highlights how the idealized concepts of liberty and democracy were challenged by the institution of slavery, leading to a complex and troubled legacy in American history.

Slavery was a paradox because it was built on the ideals of freedom and democracy, yet it involved the forced subjugation and exploitation of a group of people. The contradiction of advocating for liberty while denying it to others created a moral and ethical dilemma that challenged the principles on which societies were founded.
