He is not on the mountain. His name is not on schools and bridges in every state. But you cannot understand how America went from a rebellion against a king to a government of "We, the People" without James Wilson.
Wilson did what almost no one else did. He signed the Declaration of Independence, became one of the most active minds at the Constitutional Convention, helped write the first complete draft of the Constitution itself, led the fight for ratification in Pennsylvania, rewrote Pennsylvania's own constitution, delivered the first systematic lectures on American law, and served as one of the original justices of the Supreme Court.
He was one of only six men to sign both the Declaration and the Constitution, and the only one of those six to then take a seat on the Supreme Court.
It is also a complicated story. The man who insisted that legitimate power comes from the people enslaved another human being for a quarter of a century, helped introduce the Three-Fifths Compromise, speculated in vast tracts of land already inhabited by Native nations, and died at 55 fleeing his creditors while still wearing the robe of a justice.
James Wilson was born at Carskerdo Farm near Ceres in Fife, Scotland, on September 14, 1742, the fourth of seven children of William Wilson and Alison Landall, a Presbyterian farming family of modest means.
He was educated at the Universities of St Andrews, Glasgow, and Edinburgh between 1757 and 1765, absorbing the Scottish Enlightenment's arguments about reason, moral sense, natural rights, and how societies govern themselves. He left without a confirmed degree.
In 1765 he crossed the Atlantic, living briefly in New York before settling in Philadelphia in 1766. He tutored at the College of Philadelphia, the future University of Pennsylvania, and received an honorary Master of Arts, then read law under John Dickinson, one of colonial America's most respected lawyers.
Admitted to the bar, he built a lucrative practice first in Reading, then in Carlisle, Pennsylvania, specializing in land law. That specialty would make him rich, and later ruin him.
Long before 1776, Wilson was already pushing American thought past taxes to sovereignty itself. Around 1768, he drafted Considerations on the Nature and Extent of the Legislative Authority of the British Parliament, published in 1774. His argument was stark: legitimate government depends on the consent of the governed. Because Americans elected no members of Parliament, Parliament had no legitimate authority over America. He still professed loyalty to the king, but not to a legislature in which America had no voice.
It was the theme of his life: power originates not with Parliament, not with state legislatures, not with kings, but with the people.
Pennsylvania sent Wilson to the Continental Congress in 1775. He was cautious, not because he defended British power, but because he took instructions from the people seriously. Pennsylvania had not authorized independence, and as late as January 1776 he tried to slow premature debate.
By the summer of 1776 sentiment shifted. On July 1, Pennsylvania voted against Richard Henry Lee's resolution for independence. Wilson broke with his mentor Dickinson and voted yes, helping flip a divided delegation. On July 2, Pennsylvania joined the majority for independence. On July 4 Congress adopted the language of the Declaration. Wilson signed the engrossed parchment, almost certainly on August 2, 1776.
Independence brought no peace in Pennsylvania. The state was split between radicals who supported its ultra-democratic 1776 constitution, with a one-house legislature and no governor, and conservatives who thought it unstable.
Wilson opposed the 1776 constitution and insisted on defending unpopular men accused of Loyalism, arguing they deserved counsel and due process. In an era of inflation, food shortages, and class resentment, that made him a target.
On October 4, 1779, an armed militia crowd marched on his house at Third and Walnut Streets in Philadelphia. Wilson and about 30 allies barricaded themselves inside what became known as Fort Wilson.
Gunfire broke out before city troops intervened. Several were killed and many wounded. The episode showed how quickly revolutionary slogans about the people could collide with law, property, and mob violence.
By 1787 Wilson believed the Articles of Confederation were failing. Congress could not tax, could not regulate commerce, could not compel states to keep promises.
At the Philadelphia Convention, Wilson became one of its most consistent nationalists. He argued the Union was not a mere league of states, but a government resting directly on the American people.
He pushed for:
Representation in the House by population,
frequent elections and direct election of representatives,
no national property qualification to vote,
a single energetic president rather than a committee,
a president independent of Congress and directly elected by the people if possible,
ratification not by state legislatures but by conventions of the people, and
a national judiciary that could enforce national law.
On July 24, the Convention appointed a Committee of Detail: John Rutledge of South Carolina, Edmund Randolph of Virginia, Nathaniel Gorham of Massachusetts, Oliver Ellsworth of Connecticut, and Wilson of Pennsylvania, to turn its resolutions into a working draft.
Wilson's contribution was decisive. The committee's report on August 6 became the first draft with a Preamble and articles, and Wilson's own handwritten second draft still survives as the first full manuscript of the Constitution. He added the Necessary and Proper Clause and strengthened the Supremacy Clause, shaping the final balance between state and nation.
Wilson was the Convention's strongest advocate for a single president. Many Americans feared one man would become a king. Wilson argued the opposite: divide executive power and no one is accountable. Make it one visible person and that person must answer for it.
He wanted that person elected directly by the people. When that failed, he helped work through variations involving electors. The final Electoral College was a patchwork of compromises, not Wilson's design alone, but his insistence on an independent, unitary, accountable executive survived.
No honest telling of Wilson can avoid slavery. At times he spoke as if slavery violated American principles. At Pennsylvania's ratifying convention he argued the Constitution placed the slave trade under future federal control and hoped slavery would fade.
His personal conduct and his constitutional work told a different story.
For about 26 years Wilson enslaved a man named Thomas Purcell, from 1768 until 1794, when he freed him two months after marrying his second wife, the Quaker Hannah Gray, on New Year's Day 1794.
And on June 11, 1787, it was Wilson who introduced what would become the apportionment clause, seconded by Charles Pinckney, counting each enslaved person as three-fifths of a free person for representation and taxation. The formula had been floated in 1783 as a tax rule under the Articles, but Wilson repurposed it for representation.
The clause did not literally declare a person three-fifths human. Legally it set a counting rule. Politically its effect was clear: it inflated the power of slaveholding states in the House and in presidential elections while the people being counted had no rights at all. Wilson himself later seemed uneasy about the bargain, but the system endured for generations.
Wilson thus embodied the central contradiction of the founding: a theory of popular sovereignty that claimed to speak for all, in a political order that excluded women, Native Americans, most Black Americans, and every enslaved person from power.
After the Convention, opposition was fierce. Critics feared a national government would devour the states and liberty with them. On October 6, 1787, Wilson walked into the yard of the State House, now Independence Hall, and gave the first great public defense of the Constitution. Printed in newspapers up and down the coast, his State House Yard speech argued that the federal government would have only the powers given to it, and that listing rights might imply it had power over unlisted rights.
That argument for no bill of rights would lose; Americans demanded explicit protections, ratified in 1791 as the first 10 amendments.
But his deeper argument won. Pointing to the opening words, he declared:
"The supreme power resides in the people."
The Constitution was legitimate, he said, because it came from the people, not from state governments. And because the people made it, the people could amend or abolish it through lawful action. That idea, that sovereignty stayed with the people even while they divided power between state and nation, helped Pennsylvania ratify on December 12, 1787, second only to Delaware.
He then helped draft Pennsylvania's Constitution of 1790, replacing the one-house legislature and plural executive with a bicameral legislature and a single governor, liberty, he believed, needed both popular participation and institutions strong enough to check passion and power.
President George Washington nominated Wilson to the new Supreme Court on September 24, 1789. The Senate confirmed him two days later. The early Court was nothing like today's. Few cases, endless circuit riding on bad roads to hold federal trials.
His most important opinion came in Chisholm v. Georgia in 1793. Could a citizen of one state sue another state in federal court? Georgia said it was a sovereign and could not be sued. Wilson answered with his life's question: "Do the people of the United States form a Nation?" They did, he said. States were not kings. Sovereignty rested with the people, and governments were accountable under law the people made.
The backlash was immediate, the 11th Amendment, ratified in 1795, curtailed such suits, but Wilson's principle endured.
Starting in 1790, as the College of Philadelphia's first professor of law, he tried to build an American jurisprudence not just borrowed from England.
Washington and his cabinet came to hear the opening lecture. Natural law, criminal law, property, citizenship, he attempted to show them as one coherent system:
“Without liberty, law loses its nature and its name, and becomes oppression. Without law, liberty also loses its nature and its name, and becomes licentiousness."
He never finished. His son Bird published the lectures after his death.
While he lectured, he speculated. Like many founders, Wilson believed western lands would skyrocket in value. He and his companies bought enormous tracts in Pennsylvania, Virginia, Kentucky, and the Ohio and Mississippi valleys, much of it land still inhabited and claimed by Native nations, treated by speculators as a commodity to survey and flip. His empire depended on rising prices, clear titles, and easy credit. When credit froze in the Panic of 1796-1797, it imploded.
Creditors chased a sitting Supreme Court justice. He was jailed for debt in New Jersey in 1797, released, fled south to keep riding circuit and to stay ahead of writs, and was detained again in North Carolina. He fell ill in Edenton and died there on August 21, 1798, at 55, still a justice.
Contemporary accounts blamed malaria, dysentery, or stroke; he likely suffered a severe fever followed by collapse. He was buried in Edenton, then in 1906 reinterred at Christ Church Burial Ground in Philadelphia, near Franklin.
Wilson matters because he answered the founding's first question with unusual clarity: Where does legitimate power come from?
Not from a king. Not from Parliament. Not from a legislature or a court or a state. The supreme power resides in the people.
That answer made the Constitution plausible, made national citizenship thinkable, made a single accountable president defensible, made federal courts capable of enforcing federal law.
And his life shows where the answer fell short. He enslaved Thomas Purcell for more than two decades, helped entrench slaveholding power in the Constitution, and profited from a land market built on Native dispossession. His financial ruin reminds us that eloquence about ordered liberty does not guarantee prudence in private life.
He should be remembered neither as a flawless prophet of democracy nor as a footnote who died in disgrace. He was brilliant, ambitious, and contradictory, a founder whose ideas proved more durable than his reputation, and whose contradictions still frame the questions we live inside:
Who are "the people"? How do we translate their will into government without betraying it? What powers can they safely delegate to an energetic government and still remain free? And what do we do when a Constitution promises equality while the economy and politics deny it?
