Thomas Jefferson

Quotes verified 12/12Coverage: PARTIALWhole record

Thomas Jefferson believed slavery was a moral and political reproach and expressed a desire to see it abolished. However, he continued to hold enslaved people and drafted laws that restricted the rights of Black individuals. His conduct as a slaveholder contradicted his stated beliefs, and the record does not fully explain why he did not act on his principles.

  • undated “There must doubtless be an unhappy influence on the manners of our people produced by the existence of slavery among us.”
  • undated “It shall not be lawful for any person to emancipate a slave but by deed executed, proved and recorded... No negro or mulatto shall be a witness except in pleas of the commonwealth against negroes or mulattoes...”

Extrapolation: Jefferson's position on slavery was complex and contradictory, with his actions not fully aligning with his stated beliefs.

The full record: ledger, contrary evidence, reasoning, sources

1. WHAT HE SAID (the record)

Record ledger

  • BELIEF (1776-06): Thomas Jefferson believed that no person coming into the colony should be held in slavery under any pretext. This is a stated principle in his proposed constitution for Virginia. "No person hereafter coming into this county shall be held within the same in slavery under any pretext whatever."
  • BELIEF (1776-08-01): Thomas Jefferson argued that enslaved people should be counted as laborers whose presence does not make a state wealthier or more able to pay taxes than a state with free laborers. He believed the term 'property' applied to enslaved people created a fallacy, and that the number of laborers, not their status, determined a state's ability to pay taxes. "That it is the use of the word 'property' here, 8c it's application to some of the people of the state, which produces the fallacy."
  • BELIEF (1776-08-01): Jefferson believed that enslaved people, though not as productive as free laborers in his view, were equally the wealth of a state and should be counted equally for tax quotas. He supported a compromise proposal by Harrison to count two enslaved people as one free person, based on the argument that enslaved people were less productive. "That a slave may indeed from the custom of speech be more properly called the wealth of his master, than the free labourer might be called the wealth of his employer: but as to the state both were equally it's wealth, and should therefore equally add to the quota of it's tax."
  • ACTION (undated): Thomas Jefferson drafted a bill that imposed strict conditions on the emancipation of enslaved people, required them to leave the Commonwealth within a year or lose legal protection, and restricted the rights of Black individuals, including their ability to serve as witnesses and travel freely. This shows his position supported legal restrictions on both enslaved and free Black people. (key quote above)
  • BELIEF (undated): Thomas Jefferson believed that slavery had a degrading and corrupting influence on the manners and morals of both enslaved people and their enslavers. He argued that the existence of slavery fostered despotism, submission, and the imitation of tyranny by children, which in turn corrupted the moral fabric of society. (key quote above)
  • ACTION (editor's note) (about 1784, editor's note; editor's note, not his words): Thomas Jefferson carefully avoided any public utterance on slavery as early as 1790, and in his memoranda written in 1800, he omitted all mention of his involvement in the 1784 plan with its limitation of slavery. Additionally, he did not mention it in his Autobiography written in 1821. "Jefferson carefully avoided any public utterance on slavery. ... he carefully omitted all mention, as also in his Autobiography, written in 1821."
  • BELIEF (1785-06-07): Thomas Jefferson expressed concern that public strictures on slavery might produce irritation and hinder the emancipation of slaves, one of his 'great objects.' He looked to the rising generation for reformations, indicating his belief in the need for change, though he hesitated to act publicly on it. "It is possible that in my own country these strictures might produce an irritation which would indispose the people towards the two great objects I have in view, that is the emancipation of their slaves & the settlement of their constitution on a firmer & more permanent basis."
  • BELIEF (1785-06-21): Thomas Jefferson expressed concern that his terms regarding slavery and the state constitution might produce irritation and retard reformation, indicating he believed slavery required reform. He wished to delay the printing of his work to avoid potential backlash. "I am desirous of preventing the reprinting this, should any book merchant think it worth it, till I hear from my friends whether the terms in which I have spoken of slavery and of the constitution of our State will not, by producing an irritation, retard that reformation which I wish instead of promoting it."
  • BELIEF (1785-06-21): Jefferson expressed concerns that his terms regarding slavery might produce irritation and retard the reformation he wished to promote, indicating his belief in the need for reform regarding slavery. "whether the terms in which I have spoken of slavery and the constitution of our State, will not, by producing an irritation, retard that reformation which I wish, instead of promoting it."
  • BELIEF (1789-01-26): Jefferson believed that enslaved people could become good citizens if raised in habits of property and foresight, and he planned to experiment with this by settling his slaves and imported Germans on farms as metayers. He acknowledged the discouraging results of previous experiments with emancipation but remained committed to trying his own approach. "I shall endeavor to import as many Germans as I have grown slaves. I will settle them and my slaves, on farms of 50 acres each, intermingled, and place all on the footing of the Metayers (Medietani) of Europe."

What cuts against it

  • BELIEF (1814-09-10): Jefferson believed that enslaved people in the United States were, in some respects, better off than laborers in England, though he acknowledged their subjection to bodily coercion. "I am not advocating slavery. I am not justifying the wrongs we have committed on a foreign people, by the example of another nation committing equal wrongs on their own subjects."
  • ACTION (1792-12-03): Jefferson addressed a case involving the recapture of fugitive slaves by citizens of the United States, indicating his involvement in handling matters related to slavery. "Complaint has been made by the Representatives of Spain that certain individuals of Georgia entered the State of Florida, and without any application to the Government, seized and carried into Georgia, certain persons, whom they claim to be their slaves."

2. HOW IT APPLIES (reasoning; inference is marked)

1. Jefferson stated that slavery was a moral and political reproach, and that justice and love of country demanded action to relieve enslaved people and the nation from this condition.

2. He believed that slavery had a degrading and corrupting influence on the manners and morals of both enslaved people and their enslavers.

3. Jefferson proposed that no person coming into the colony should be held in slavery under any pretext, indicating a principled opposition to the institution.

4. Despite these beliefs, he drafted a bill that imposed strict conditions on the emancipation of enslaved people and restricted the rights of Black individuals. (inference: this action contradicts his stated belief in the need for reform.)

5. He carefully avoided public utterance on slavery as early as 1790 and omitted all mention of his involvement in the 1784 plan with its limitation of slavery in his memoranda and autobiography. (inference: this suggests a deliberate effort to distance himself from his earlier anti-slavery positions.)

3. HIS TAKE

Record coverage: PARTIAL

The record is silent on Jefferson's personal justification for continuing to hold enslaved people despite his stated opposition to slavery.

Extrapolation: Jefferson's position on slavery was complex and contradictory. He expressed strong moral opposition to slavery and believed it was a moral and political reproach, yet he continued to hold enslaved people and drafted laws that restricted the rights of Black individuals.

Competing readings: One reading is that Jefferson's actions were a result of political pragmatism and the desire to avoid public backlash. Another reading is that he genuinely believed in gradual reform and the need for a practical plan to abolish slavery. The record itself states that he looked to the rising generation for reformations and expressed a willingness to sacrifice everything for a practicable plan to abolish slavery.

Confidence: Moderate. The record provides clear evidence of Jefferson's stated beliefs and actions, but the reasons for the discrepancy between the two are not fully explained by the record itself.
