Ex Conatu, Libertas
A family creed for the age of comfort
Thomas Jefferson crossed out a word and changed the meaning of freedom for two and a half centuries.
George Mason’s Virginia Declaration of Rights, drafted weeks before Jefferson sat down to write the Declaration of Independence, listed the inherent rights: life, liberty, property, happiness, and safety. Jefferson kept life. He kept liberty. He dropped property. In its place, he elevated three words that have been misread ever since: the pursuit of happiness.
I believe I know what he meant.
Jefferson was, by his own private confession, an Epicurean. In an 1819 letter to his friend William Short, he said it plainly: “I too am an Epicurean.” He enclosed a syllabus of Epicurean doctrine, stripped to its bones:
Happiness the aim of life.
Virtue the foundation of happiness.
Utility the test of virtue.
Read those three lines slowly. Happiness is the aim. But you cannot reach it without virtue. And virtue is measured by its usefulness: its effects on the world, its contribution to others, its capacity to produce something that matters. Jefferson’s happiness was a framework for effectiveness. For producing. For participating.
He told his daughter Martha the same thing in plain language, writing from a canal boat in southern France in 1787: “A mind always employed is always happy. This is the true secret, the grand recipe for felicity. The idle are the only wretched.”
The idle are the only wretched. Struggle, challenge, effort: those were the mechanisms of happiness in Jefferson’s architecture. Passivity and disengagement were its enemies.
His remaining purpose in life, he told Martha, was seeing his daughters “developing daily those principles of virtue and goodness which will make you valuable to others and happy in yourselves.” Valuable to others AND happy in yourselves. The two weren’t separate categories. Usefulness to others was the mechanism of personal happiness.
The enemy of happiness in Jefferson’s framework is not suffering. It’s what he called “the most dangerous poison of life”:
Ennui.
Passivity.
Disengagement.
Doomscrolling.
The withdrawal from useful activity that rots character from the inside.
We’ve turned his word into something he wouldn’t recognize. Happiness has become a feeling to be optimized, a mood to be managed, an arrival to be reached and defended against disturbance. We track it on apps now. Jefferson meant something closer to effective engagement with reality through virtue: being productive, being useful, developing character through activity, and through all of that, arriving at flourishing. The pursuit was the point. The happiness was in the pursuing.
The drive beneath the Declaration
There is a deeper current running beneath Jefferson’s framework, one he never named.
A century before the Declaration, Spinoza had a word for it: conatus. The fundamental drive of every being to persist in and expand its own existence. Not survival, exactly. Something more stubborn than that. A plant turning toward light isn’t deciding to grow. It just grows. Conatus is that: the core motion of a living thing, pressing outward against whatever constrains it.
And freedom, in Spinoza’s architecture, is the achieved state of acting from your own nature rather than being shoved around by external forces.
Freedom earned through understanding and effort. Never granted. Never inherited without renewal.
Ex Conatu, Libertas. From striving, freedom.
Where did Jefferson’s version come from? He may never have read Spinoza directly. The influence was atmospheric: Spinoza’s ideas passed through the radical Enlightenment and entered the intellectual air that Jefferson breathed without tracing it back. But the convergence is striking. Jefferson’s substitution of “the pursuit of happiness” for “property” shifted freedom from static possession toward active striving. His conviction that the moral sense must be exercised and cultivated, his vision of the yeoman farmer realizing capacity through self-directed labor: all of it resonates with conatus more than with Locke’s framework of natural rights.
Both men arrived at the same insight from different directions. Striving constitutes freedom. Passivity negates it.
What you can’t put in a constitution
But Jefferson made a choice that I think contains the deepest wisdom in the whole architecture.
He kept all of this privately.
His public philosophy remained Lockean: natural rights, consent of the governed, limited government as a shield against tyranny. He built institutions on Locke because institutions require bright lines. A republic must answer questions like: Where does your freedom end and mine begin? What constrains the sovereign? What rights can’t be taken away? Conatus offers no answers to these questions. It is concerned with a being’s relation to its own nature, not with the architecture of competing wills.
Some truths constrain power, bound authority, draw lines between people. A republic runs on these. A courtroom runs on these. They have to be enforceable, or they’re decoration.
Other truths shape character. They orient a person toward the world, cultivate something in them that no legal code can reach. A family runs on these. A mentor runs on these. They work precisely because no one is forced to follow them.
You cannot legislate striving. Try, and you get either authoritarianism (the state defining what counts as proper effort) or emptiness (a principle so abstract it constrains nothing). You cannot put conatus in a constitution. But you can build a household around it. You may, at its largest scale, create a culture of it.
A family doesn’t operate on enumerated rights. It operates on shared identity, obligation, modeling. The goal is character formation. And within that context, the claim that freedom is earned through effort, that passivity negates it, that the idle are the only wretched: these lose none of their force for being unlegislatable.
Jefferson understood this. He held one philosophy for the republic and another for himself and his household. He was right to keep them separate.
As a family creed, Ex Conatu, Libertas locates freedom in agency rather than entitlement. It tells children they are free because they pursue freedom through their own striving, choosing it each day. Not a gift. An ongoing achievement, something that can atrophy through neglect the way a muscle does.
It carries a useful severity. The person who ceases to strive has ceased to be free, regardless of how comfortable the couch is. This is a demanding standard. Deliberately. Jefferson told his daughter the idle are the only wretched. He didn’t soften it.
And it inoculates against what I think is the quiet disease of our particular moment: the slow substitution of ease for agency, of consumption for creation. I watch it in myself. The drift toward optimization, toward managing life rather than living it. The creed functions as a standing challenge. Remain an active author of your own life. Provide value. The capacity for self-governance starts in the smallest republic: the family.
This is why I named the publication what I named it. Prometheus saw humans shivering in the dark. He didn’t petition Zeus. He didn’t wait for permission. He stole fire, brought it down, and accepted the eagle as the price. That’s conatus in its mythic form: the drive to act on what you know, to bring light even when the cost is visible from the start. The creed and the myth are the same argument. Striving constitutes freedom. The fire has to be carried. And the carrying is the point.
I chose these words knowing they can’t be made into law.
A creed that could be legislated would have already lost its meaning. Compelled striving is compliance. Only freely chosen effort constitutes what Spinoza meant, what Jefferson practiced, what I want my children to understand about what it means to be free.
Some truths belong to the household. They enrich the individual and shape the family, and they fall apart the moment you try to enforce them on strangers with no shared context. Jefferson knew this. He built bright lines for the republic and kept his Epicurean notebooks for himself.
Ex Conatu, Libertas. From striving, freedom. The philosopher’s private conviction. The patriarch’s standing challenge.
A mind always employed is always happy. The idle are the only wretched. I believe this. I want my children to believe it too. Not because I told them. Because they felt it: the moment you realize your own capacity, the weight you can carry, the thing you built that wasn’t there before. That feeling is the freedom. Once you’ve had it, comfort stops being enough.
That’s the creed’s final demand. Even its acceptance must be earned.
