This paper examines the profound tension in Thomas Jefferson's views on slavery and his real-world actions. Drawing on three major texts—"A Summary View of the Rights of British America" (1774), the Declaration of Independence (1776), and "Notes on the State of Virginia" (1784)—the paper traces how Jefferson's Enlightenment idealism coexisted with deep political pragmatism and personal contradictions. The analysis reveals a man who believed, in principle, that slavery was wrong and that all men are created equal, yet never translated those convictions into meaningful action. The paper also considers the Sally Hemings controversy as a further lens through which Jefferson's dualism can be examined, ultimately concluding that political caution and fear of national instability drove the gap between his rhetoric and his conduct.
One of the Founding Fathers and among the most consequential political figures in world history, Thomas Jefferson is also a deeply controversial figure given his views on slavery — an area where his theoretical positions did not always align with his actions. Throughout his life, Jefferson found himself torn between his own Enlightenment-influenced political convictions, expressed in key documents such as the Declaration of Independence, and his belief that the abolition of slavery would cause civil war and instability for the new nation. Because of this dualism, Jefferson's conduct was perpetually divided between the antislavery ideals that Enlightenment philosophy proposed — including the principle that all men are created equal — and the practical necessity of maintaining political stability.
Born into a slave-owning family in Virginia, Jefferson grew up with enslaved people on his father's property, and his opinions soon began to support an incipient antislavery movement. As early as 1770, he argued on behalf of a Virginia slave named Samuel Howell, seeking his freedom on the grounds that "all men are born free" — a concept later integrated into the Declaration of Independence. Many of his writings characterize slavery as an unjust institution. Yet he was never quite able to reconcile his rhetoric with the actions of his own life.
This paper discusses the dualism between Jefferson's stated views on slavery and his personal conduct, and analyzes several of his writings in order to better understand his beliefs. The texts examined include "A Summary View of the Rights of British America," the Declaration of Independence, and "Notes on the State of Virginia." The paper also considers his relationship with Sally Hemings, one of his own enslaved people, with whom he is believed to have fathered several children.
"A Summary View of the Rights of British America" was written in 1774 as a political document in which Jefferson aimed, on one hand, to demonstrate to the King of Britain how he had wronged his American colonial subjects and, on the other hand, to argue for a free America. Jefferson's rhetoric invokes the issue of slavery, though largely to show that the King had disregarded the legislative wishes of his American subjects rather than to make a primary abolitionist argument.
Jefferson refers to "the abolition of domestic slavery" as a "great object of desire where it was unhappily introduced in their infant state." On its surface, this phrase signals a commitment to abolition. However, the argumentation is not entirely convincing. Slavery may have been introduced under British rule, but it had become deeply embedded in the colonial economy, and it was the colonists themselves who perpetuated it. Just as Jefferson could not part with his own enslaved people, countless colonists regarded slavery as inseparable from their economic survival.
The second part of this passage does point toward a more pragmatic abolitionist approach. Jefferson outlines a two-step process for eliminating slavery: first, halting the importation of new enslaved people from Africa, and second, considering the gradual emancipation of those already enslaved:
"But previous to the enfranchisement of the slaves we have, it is necessary to exclude all further importations from Africa. But previous to our repeated attempts to effect this, by prohibitions, and by imposing duties which might amount to a prohibition."
The Declaration of Independence is perhaps the clearest expression of Jefferson's theoretical ideals, since he drafted the majority of the document and it therefore closely reflects his own views. The most significant passage in relation to slavery is the declaration that "all men are created equal." This statement, consistent with the principles of eighteenth-century Enlightenment — a philosophical tradition Jefferson embraced — encompasses all men, not white males alone. Given his grounding in Enlightenment thought, Jefferson almost certainly intended this as a universal statement, one of principled idealism that proposed equality for all. Abraham Lincoln would later invoke precisely this universality when championing emancipation.
Nevertheless, as British abolitionist Thomas Day observed at the time, "if there be an object truly ridiculous in nature, it is an American patriot, signing resolutions of independency with the one hand, and with the other brandishing a whip over his affrighted slaves." This remark captures the fundamental contradiction of the era: slavery was woven into the social and economic fabric of American life, having been established since the seventeenth century.
For Jefferson, as an Enlightenment thinker, proclaiming the equality of all men was far easier to accomplish on paper than to enact across an entire nation. The political obstacles were immense: the southern states especially depended on slavery as a way of life, and moving toward abolition simultaneously with declaring independence from Britain might have fractured the coalition of the thirteen colonies, potentially dooming the independence effort altogether. The Constitution's proclamation of the "sacred right of self-government" further complicated any federal antislavery initiative.
The most reasonable interpretation of Jefferson's position in the Declaration is that he recognized the political impossibility of proposing abolition during a war that required the unity of all thirteen states. Rather than abandon the ideal entirely, he chose to embed the principle that "all men are created equal" into one of the nation's founding documents, leaving the door open for future generations. It bears noting that the Declaration was fundamentally a political act of separation from Britain — not an instrument for the liberation of enslaved people in the American colonies.
"Notes on the State of Virginia" was published in 1784 and contains, particularly in two chapters — Chapter XIV on laws and Chapter XVIII on manners — several references to slavery, some of them quite controversial given Jefferson's background and the positions he expressed in the Declaration of Independence. Written a decade after "A Summary View," this work addresses the United States as an already established independent nation. As a result, some of Jefferson's views shed their practical political urgency and return to a more theoretical and idealistic register. This is most apparent in the chapter on manners.
"Contradictory racial views in Jefferson's 1784 work"
"Personal controversy deepens Jefferson's contradictions"
The analysis in this paper has shown that Jefferson was one of the foremost representatives of the Enlightenment, and his writings provide ample evidence of that intellectual heritage. His theoretical work reflects an idealistic conviction that slavery is wrong. Despite the unusually racist passages in "Notes on the State of Virginia" (1784), the overall trajectory of his writings tends toward condemnation of the institution. Yet he never translated this conviction into meaningful action. His words remained on the page and were not acted upon.
