In Our Failure, Our Duty, David McCullough explains that we need more historians who have the heart and humanity necessary to help students imagine the lives of people who have lived in the past and were just as human as we are today.
In 1857, the Dred Scott v. Sanford case took place because Dred Scot, a Missouri slave, was brought to the free state of Illinois and free territory of Wisconsin.
It was ruled that slaves were private property and could be brought anywhere as a slave. The 5th Amendment protected owners' rights of property.
By understanding Dred Scott and what his life experiences, it helps modern historians to have an understanding for what he went through and to feel for him. It comes to a shock to see the treatment of slaves and how they were considered "property".
With an overall understanding of the Dred Scott v. Sanford case, it comes to show how cruelly African Americans were treated. As McCullough explained, we are all human and equal. This goes for the past, present, or future. Having an open and sympathetic mind is key to realizing we are all human and perfectly imperfect.
