The Ship of Theseus

Published September 21, 2026 at 11:03 am CDT

I have had the same conversation in a hundred meeting halls, and it usually ends in the same place. A man stands up during the questions. He is not hostile and he is not a crank. Nine times out of ten he has read more constitutional history than anybody else in the room, and what he wants me to know is that he doesn’t want independence. He wants the Constitution enforced. The Tenth Amendment honored, the spending brought to heel, the agencies cut back, the courts held to the text. He wants the thing we have now put back to the thing it was.

I like that man. I was that man for years. And I ask him one thing in return.

“Returned to what?”

The question is not a debating trick. Underneath his whole position sits a premise he has never had occasion to examine. The premise is that the government in Washington is the government the States ratified, in poor condition, and that a thing in poor condition can be repaired back into what it was. I don’t think that premise survives contact with the record. And if the premise is false, then every Tenth Amendment resolution passed by a State legislature in the last thirty years was aimed at a vessel that is no longer in the water.

An old puzzle about a ship states the difficulty better than any constitutional argument I know.

Plutarch’s ship

Plutarch tells it in his life of Theseus, written near the end of the first century. When Theseus came home from Crete, the Athenians kept the galley he had sailed in. Thirty oars. They kept it for centuries, down to the time of Demetrius of Phalerum, about three hundred years before Christ. A wooden ship can be kept only by repairing it. As the timbers rotted the Athenians drew them out and set sound ones in their place, one plank and then another, and by the end there was very little of the original galley left in the water.

Plutarch says the vessel became a standing illustration for the philosophers, some holding that it remained the same ship and others holding that it did not.

What makes the puzzle hard is that nothing went wrong. Every replacement was lawful, ordinary, and necessary. Nobody stole the ship and nobody scuttled it. Athens maintained the vessel exactly the way a careful owner is supposed to maintain one, and at the end of all that careful maintenance there was still a real question about whether the thing in the water was the thing Theseus sailed.

The federal government of 2026 is not the government the States ratified between 1787 and 1790. Nearly every plank in it has been drawn out and replaced. A few of those replacements were made by the owners, in the open, by the procedure the plan itself provides. Most were not. What sits in Washington now is a later vessel, built inside the hull of the first one and carrying its name.

That is a question of identity rather than a question of policy, and every claim of obligation rests on it. Consent runs to a party. When a Texan is told he is bound by what his State agreed to in 1845, the whole force of the telling depends on whether the thing collecting from him today is the thing that was agreed to then.

The planks that were pulled

Start with 1913, which took out three of the heaviest timbers inside twelve months. In February the Sixteenth Amendment let Washington tax incomes without apportioning the tax among the States, so the federal government no longer had to reach a man through his State in order to reach his pocket. In December the Federal Reserve Act moved practical control of the currency. And in April, between the two, came the Seventeenth Amendment, which took out the keel.

Until 1913 the State legislatures chose the senators. That made the States something more than large constituencies. They held an office inside the federal government, and Federalist 62, which the record generally assigns to Madison, said clearly that this was the point of the design, to give the State governments “such an agency in the formation of the federal government as must secure the authority of the former.” After 1913 the States, as States, held no officer, no vote, and no seat in the government they had created. They have held none since.

Then the work went below the waterline, where the owners could not watch it and were not asked.

In 1942 the Supreme Court decided Wickard v. Filburn. Roscoe Filburn was an Ohio farmer who grew wheat on his own ground and fed it to his own animals. He never sold a bushel of it and it never left the farm. The Court held that Congress could regulate the wheat as commerce among the States, on the reasoning that what Filburn grew was what he did not have to buy. The Court has trimmed that reasoning since, in the school gun case in 1995, the violence against women case in 2000, and the insurance mandate in 2012. Under the plan, a lawyer defending an act of Congress has to find the power on a list. Under the practice, a lawyer attacking one has to find an exception. Nothing in Article I was amended to produce that. The burden of proof changed hands, and no State was asked about it.

South Dakota v. Dole, in 1987, shows the same thing done with money instead of doctrine. Congress had withheld five percent of a State’s federal highway funds from any State that would not set its drinking age at twenty-one. The Court upheld the arrangement and every State came into line. South Dakota’s legal authority over its own drinking age was never touched, not for a single day. Washington did not take the power. It bought the exercise of it with money it had already taxed out of South Dakota. That same arrangement now runs through the schools, the highways, the hospitals, and the sheriff’s office.

The war power went the same way, more slowly, without any one case to mark the moment. Congress last declared war in June of 1942, against Bulgaria, Hungary, and Romania. Korea, Vietnam, Grenada, Panama, the Gulf, the Balkans, Afghanistan, Iraq, and Libya were all fought on something else: authorizations, resolutions, treaty commitments, and in a few instances nothing at all. The framers put that power in the hands of the people’s own representatives because it is the gravest power in the document. It moved anyway, one precedent at a time, and no State was ever asked about that either.

The administrative machinery came last and is the largest of the changes. The Administrative Procedure Act of 1946 built it. Chevron, in 1984, told the courts to defer to an agency’s reading of the statute that empowered it, and for forty years they did. The Supreme Court overruled Chevron in Loper Bright in June of 2024. That was a genuine correction and I am not going to talk it down, but the regulations are still on the books, the agencies are still writing more of them, and nobody who writes a line of federal regulation stands for election in Texas.

Two of the changes on that list were ratified by the States. The rest were never put to anybody.

Athens used sound timber

The comparison to Athens breaks down at one point, and it breaks down against Washington.

The Athenians put sound planks in where the rotten ones came out. That is what keeps their puzzle clean. Nothing was lost in any of those swaps except old wood, and the galley that came out of each repair was as seaworthy as the one that went in. The philosophers could argue about identity precisely because seaworthiness was not in question.

The pieces pulled out in Washington all carried the same load. A limit. Apportionment limited what could be taken. The State legislatures’ hold on the Senate limited what could be consolidated. A declaration of war limited what could be spent on other people’s quarrels. The enumerated list limited what could be attempted at all. Four different mechanisms doing one structural job: keeping the vessel from taking on more than it can carry.

What went in where they came out was a discretion in every instance. Taxation without apportionment. An elastic currency. A Senate that answers to money raised outside the State. A commerce power that reaches a man’s own wheat. A war power exercised out of one office. A body of regulation written by people who never stand for election anywhere. Every one of those was sold as capability, and every one of them genuinely is. Not one of them carries any load against the ship taking on water.

Treasury keeps the ledger, so the result is not a matter of opinion. In July of 1913, the year the first three timbers came out, the federal debt stood at $2.9 billion. On the seventeenth of September this year it stood at $40.09 trillion. Both of those are Treasury’s own figures in Treasury’s own nominal dollars, and the second one was four days old when I looked it up.

That is not a charge against any administration, and it is not a forecast. It is a reading off an instrument. Every mechanism that used to limit federal borrowing was taken out, deliberately, one at a time. The borrowing followed.

I take no satisfaction in any of it, and I am not going to name a year. Nobody serious names a year. The point is narrower and harder to get around: a people lashed to a vessel it does not steer has every interest in that vessel’s soundness and no say in it whatsoever.

That is the second charge, and it is the heavier of the two. The thing in Washington is a different ship from the one the States built. It is also a worse one, refitted so that it cannot stop doing the thing that will eventually put it under.

The refit was allegedly lawful

The best objection to all of this comes from people who actually know the document, and it deserves an answer rather than a wave.

The objection is that the plan provides for its own alteration. Article V is right there in the text. A plank pulled by the owners’ own procedure is maintenance rather than theft, and maintenance is exactly what Athens was doing. Refit a ship according to the ship’s own rules and you still have the ship.

The first half of my answer is a concession. The Sixteenth and Seventeenth Amendments went through Article V. Congress proposed them and the legislatures of the States ratified them, and nobody smuggled anything past anybody. The States did that to themselves, in broad daylight. If every change had come that way, I would owe the man in the meeting hall a different answer than the one I give him.

But Wickard was not ratified. Dole was not ratified. No State legislature ever voted on the migration of the war power, and no convention anywhere approved the Code of Federal Regulations. Those changes came by construction, by deference, and by the ordinary tendency of any body on earth to read its own commission generously. Athens at least pulled its planks on deck, in front of the city. This work was done on the hull, underwater, by the crew, and the owners were told the refit was routine.

The second half of the answer goes to what makes the objection feel strong. Every Athenian replacement was lawful. Plutarch says so. The philosophers argued for two thousand years anyway, because the lawfulness of each step tells you nothing whatever about the identity of the whole. A procedure for replacing a plank is not a procedure for replacing a ship. And nothing in Article V speaks to seaworthiness at all. A “lawful” refit can still sink a boat.

Locke’s question

The useful move here comes from Locke, who was not writing about ships at all.

In 1689, in the second book of the Essay Concerning Human Understanding, Locke gave a chapter to identity. He points out early in it that “is it the same” has no answer at all until you say the same what. The test for sameness depends on what kind of thing you are asking about, and the kinds do not share a test.

For a mass of matter, identity is the matter. Take a particle away and you have a different mass.

For an oak, identity is nothing of the sort. The oak in the yard shares almost no matter with the acorn it came from. Locke says it is the same oak because it holds “such an organization of parts in one coherent body, partaking of one common life.” The matter pours through and is replaced continuously, the organization continues, and the sameness lives in the organization rather than in the wood.

For a person, Locke says identity is continuity of consciousness, which is the hardest case of the three and not ours today.

So before anybody argues about the ship in Washington, put Locke’s question to it. What kind of thing is a government.

It is not a mass of matter, and it is not a living body, whatever the poets have done with that image. It is a made thing, built to a written plan, by identified owners, for a stated purpose. The plan and the owners are both on paper and anyone may read them. For that kind of thing, identity cannot ride on the timber, because the timber is the part that was always going to be replaced. It rides on the plan and on the owner.

Which leaves two questions, and they are the two the man in the meeting hall and I actually disagree about.

Does it still run on the plan. The plan is a grant. Article I, section 8 lists what Congress may do, and the Tenth Amendment says the remainder was never handed over at all: reserved to the States respectively, or to the people. The federal constitution runs in one direction only, no power except the list. A State constitution runs the other way. It limits a government that already holds the police power over the ordinary life of its people. Ask a working lawyer today to name a subject Congress may not reach. He will not hand you the list. He will hand you a short stack of recent cases carving out exceptions, and those two answers do not describe the same document.

Does it still answer to the owner. Article VII says who the owners were. The plan took effect “between the States so ratifying the Same.” Nine of them made it, and it bound only the ones that ratified. Each acted through its own convention, separately, and every one of them was free to stay out. Those States held the Senate, the amendment power, and everything not delegated. Today they choose no senator, hold no officer of their own inside the federal structure, and keep their own laws subject to spending conditions they were taxed to fund. An owner who has to ask permission to change a rule in his own house, and pay for the asking, is not an owner.

Both answers come back no, on the criterion Locke gave for exactly this kind of thing. And Locke is no hostile witness. He is the man whose account of rights the founding generation was working from.

Who gets to answer

In Athens the argument was free. Nobody owed that ship anything. It sent no bills, tried no cases, and drafted no sons.

Ours does all three, so the identity question arrives at a Texan’s door with a tax attached, a court attached, and in some generations a war attached. It is also decided by one of the parties to it, since the extent of federal power is determined by the federal government. That is not a conspiracy. It is just the structure, and no structure that lets a party rule on the scope of its own commission has ever produced a narrow result.

Other places have handled it another way.

In 1998 the Supreme Court of Canada took the question head-on in Reference re Secession of Quebec. It held that Quebec had no right to leave unilaterally. Then it held the second half. A clear majority of Quebeckers, voting on a clear question, would place a reciprocal obligation on the rest of Canada to come to the table and negotiate in good faith. Parliament wrote the standard into statute in the Clarity Act of 2000. Canada is still there.

In October of 2012 the Prime Minister of the United Kingdom and the First Minister of Scotland signed the Edinburgh Agreement, and on the eighteenth of September, 2014, Scots voted on whether to go. They voted to stay, fifty-five to forty-five. The United Kingdom is still there, and the consent holding it together was counted that afternoon instead of assumed.

Neither country came apart from having the question put. Both of them now rest on a consent they can produce on demand, dated and counted. Washington rests on an assumption about 1845 that has never once been tested, and it governs on the strength of that assumption every day.

The old planks are on the shore

Hobbes added the other half of the puzzle in 1655, in the chapter on identity and difference in De Corpore, and that half belongs to Texas.

Suppose, Hobbes said, that somebody kept the old planks as they came out and later put them back together in the same order. Now there are two ships in the water, and both have a claim to the name. He called the result absurd and used the absurdity to make his point, which is that “the same” means nothing until you say in what respect. One ship is the same in form. The other is the same in matter. They cannot both be the same in every sense.

The old planks are not at the bottom of the harbor.

Texas can produce the receipts on every piece of its own timber. A declaration of independence on the second of March, 1836. A field at San Jacinto seven weeks later that settled it. Nearly ten years as a recognized republic with its own treaties, its own ministers in London and Paris, and its own debt. An entry into the union in 1845 by act of its own convention and its own congress, as a party to a compact and not as territory admitted by anyone’s grace. None of it is in dispute. The other party’s archives say the same thing ours do.

Restoration is the accurate word for what Texas is asking, not a gentler one. A people that gathers up the timbers it never gave away and builds with them has destroyed nothing. It is building the older ship.

The timber

Consent is given to a thing and not to a name. Change the plan, change the owner, and the old consent does not carry over to what is left because somebody repainted the name on the bow. That is not an exotic doctrine. It is how every contract on earth already works, and we make an exception only where the party who benefits is also the party writing the rules of evidence.

Which brings us back to the man in the meeting hall. He wants to know how we get the ship back. We do not get the ship back. Repair is not on the table. The crew that spent a century rebuilding that vessel will not be talked into rebuilding it in the other direction, and there is nothing left in the plan that provides a way to make them. The members that used to provide the way are the ones that came out.

What is left is the timber, and the question of what a people does with timber it still owns. Staying aboard is an answer to that question too. It is the one that lets the water decide.

That question has been open since the second of March, 1836, and it has never once been Washington’s to answer.
