In modern day, the greater portion of American scholars and historians


 recognize that Jefferson did in fact have a relationship with Hemings.  


Through journalism, Callender was able to critique Thomas Jefferson 


and expose the hypocrisy of Jefferson’s actions overtime. Jefferson


 justified slavery by referring to Black people as subhuman and less 


than white people. 

Thomas Jefferson wrote that “all men are created 

equal,” and yet enslaved more than six-hundred

 people over the course of his life.
Thomas Jefferson called slavery a “moral depravity” and a 

“hideous blot,” but continued to hold human beings as property

 his entire adult life.

(Jefferson discussing the Missouri question and slavery to John Holmes 


April 22, 1820. Ford, Paul Leicester, ed. The Works of Thomas Jefferson, 


Volume 12. New York: G.P. Putnam's Sons, 1905, p. 159.)



We have the wolf by the ears 



and feel the danger of either



holding or letting him loose."


(Jefferson to Mrs. Sigourney, Monticello, July 18, 1824.)



Despite writing that "all men are created equal," Thomas Jefferson


 enslaved over 600 people during his lifetime. Although he made


 some legislative endeavors against slavery and grieved its existence 


at times, he also benefited directly from it and declared in his Notes 


on the State of Virginia that he regarded black people to be inferior 


to white people.



Thomas Jefferson was an outspoken opponent of slavery throughout


 his life. Slavery, he saw as a "moral depravity" and a "hideous blot," he


 saw as the greatest threat to the fledgling American nation's survival. 


 Jefferson also believed that slavery violated natural laws, which said that 


everyone had the right to personal liberty. These views were radical in a 


world where unfree labor was the norm.



During the American Revolution, Jefferson was actively involved in 


legislation aimed at abolition of slavery.



In 1778, he wrote a Virginia statute prohibiting the entry of enslaved 


Africans.



In 1784, he proposed an edict that would outlaw slavery in the 


Northwest regions.



However, Jefferson always maintained that the decision to


 emancipate slaves would have to be part of a democratic process; 


abolition would be stalled until slave-owners agreed to release their 


human property in a large-scale act of emancipation. To Jefferson, it 


was anti-democratic and antithetical to the values of the American 


Revolution for the federal government to enact abolition or for only 


few planters to free their slaves.


Despite Jefferson's continuous support for abolition, slavery's 


hold on the country was growing. Virginia's slave population 


increased from 292,627 in 1790 to 469,757 in 1830. Jefferson 


believed that abolishing the slave trade would weaken slavery 


and hasten its demise. Instead, slavery spread and became more


 profitable. To weaken Virginians' support for slavery, he 


discouraged the cultivation of crops that relied significantly on


 slave labor, notably tobacco, and encouraged the introduction 


of crops that required little or no slave labor, such as wheat, sugar 


maples, short-grained rice, olive trees, and wine grapes. By the 


1800s, however, Virginia's most valuable product and export was 


slaves, not crops or land.



Jefferson's confidence in the urgency of abolishing slavery 


remained constant. He campaigned for progressive liberation from 


the mid-1770s until his death. The transatlantic slave trade would 


be eliminated first. Second, slave owners would "improve" slavery's 


most heinous aspects by improving (Jefferson used the phrase 


"ameliorating") living conditions and reducing physical punishment. 



Third, all slaves born after a specific date would be declared free, 


followed by final abolition. He, like others of his time, advocated for


 the expulsion of newly freed slaves from the United States. The 


unexpected consequence of Jefferson's strategy was that his goal of 


"improving" slavery as a step toward its abolition was used to justify


 its continuation. After Jefferson's death, pro-slavery proponents 


claimed that if slavery could be legalized, it should be.



Jefferson's abolitionist ideals were linked with his racial beliefs. 


He believed that white Americans and enslaved Africans were two 


"different nations" that could not coexist peacefully in the same country. 



Jefferson's opinion that blacks were racially inferior and "as incapable


 as children," combined with slaves' supposed animosity of their former


 masters, made their freedom an essential component of Jefferson's 


emancipation strategy. Jefferson, influenced by the Haitian Revolution


 and an unsuccessful uprising in Virginia in 1800, believed that 


deporting American slaves—whether to Africa or the West Indies


—was a necessary step after liberation.



Jefferson described slavery as "having a wolf by the ear, and we can


 neither hold him nor safely let him go." Slavery, he believed, would


 ruin his beloved federal union, the world's first democratic experiment.



 Jefferson believed that emancipating slaves on American soil would 


result in a large-scale race war as violent and fatal as the slave 


insurrection in Haiti in 1791. But he also believed that keeping slaves


in bondage, with a portion of America in support of abolition and a 


portion of America in favor of preserving slavery, could only lead to


 a civil war that would destroy the union.



Jefferson's latter forecast came true: the debate over slavery produced 


a violent civil war and the formation of two nations—the Union and


Confederacy—instead of one.
