Isaacson’s analysis of the Declaration of Independence centers on the deep contradiction at the heart of the American founding: the declaration that “all men are created equal” (1) in a nation that institutionalized chattel slavery. The book presents this hypocrisy as a defining moral conflict of the revolutionary era, one reflected in the personal lives and political decisions of the Founders themselves. Isaacson demonstrates that this contradiction was consciously debated, legally encoded, and passed into American political life as an unresolved struggle over the meaning of equality and freedom. 

The book illustrates how this contradiction became embedded in debates surrounding law, rights, and independence during the revolutionary period. The Virginia Declaration of Rights, adopted just a month before the Declaration of Independence, shows how revolutionary ideals were already being limited in practice. Its author, George Mason, originally stated that all men possessed inherent natural rights. However, the document was amended to clarify that these rights apply only to men “when they enter into a state of society” (14), a clause explicitly added to exclude enslaved people from its protections. Isaacson uses this revision to show that many revolutionary leaders understood the contradiction between slavery and natural rights yet still created political frameworks that preserved enslavement while promoting the language of liberty.

The contradiction is most powerfully embodied by Thomas Jefferson, the Declaration’s principal author. Isaacson highlights the stark contrast between Jefferson’s rhetoric about liberty and his personal life. In his original draft, Jefferson condemned the slave trade as a “cruel war against human nature” (14), yet he personally enslaved more than six hundred people over his lifetime and freed only a handful, even in his will. The book also connects Jefferson’s contradictions to broader Enlightenment influences on the revolutionary generation. John Locke, whose political philosophy strongly influenced many American revolutionaries, argued that individuals possessed natural rights independent of monarchy or inherited authority. At the same time, he profited from investments in the Royal African Company. These examples demonstrate that some intellectual traditions influencing the American Revolution coexisted with systems of enslavement and racial inequality.

This conflict extended from the personal to the political, as the Continental Congress chose political unity and compromise over condemning slavery directly. The delegates edited out Jefferson’s passages condemning the slave trade, a decision influenced by the fact that 41 of the 56 signers were enslavers. Isaacson also emphasizes that these contradictions were recognized by some contemporaries during the revolutionary period itself. Abigail Adams directly criticized the contradiction between revolutionary ideals and slavery, writing to Jefferson that it was a “contradiction that must wound the conscience of every honest man” (16). Her pointed questions reveal that the contradiction between liberty and slavery was apparent even in 1776. Isaacson ultimately presents this contradiction as an enduring conflict within American history, one later confronted by figures such as Abraham Lincoln and Martin Luther King Jr. as they pushed the nation toward a more inclusive understanding of equality and citizenship.
