Ideal Theory Empties Position

A Theory of Justice · John Rawls · 29 June 2026


WORK

In A Theory of Justice, Rawls asks what principles of justice rational parties would choose behind a veil of ignorance, without knowing their own place in society.

WHY IT MATTERS TO BOUNDARYISM

Rawls gives modern political philosophy one of its most influential images of fairness: remove knowledge of position, and the principles chosen will not be biased by position. Because no one knows whether they will be strong or weak, rational parties will protect the weak — this is the reasoning behind the difference principle, and it is the strongest reply Rawls offers to any theory that begins, as Boundaryism does, from position.

So the disagreement is not where it first appears.

BOUNDARYISM RESPONSE

It would be easy, and wrong, to say that Rawls ignores position. He does not. The veil removes knowledge of position precisely so that no one can write the rules to favor the position they happen to occupy. A rational party who might turn out to be the worker, the migrant, the rider, will not design principles that abandon them. Out of this comes a commitment to the least advantaged.

Position is not ignored behind the veil. Its influence on the choice of principles is deliberately removed.

The disagreement is about when.

Rawls removes position at the moment principles are chosen. Boundaryism is concerned with what happens after principles begin to operate. These are different questions, and the answer to the first does not settle the second.

A labor law may be chosen fairly. It may genuinely protect those it was written for. Over time, technologies change, markets reorganize, institutions adapt, and new forms of work emerge. Cost moves downward. Exit grows expensive.

The law has not changed.

The structure has.

The people now standing inside that structure occupy positions the original choice never saw — positions in which what they must bear, what they can contest, and whether they can leave have all quietly been redistributed.

The one who defines is not in the position of the one who is defined. The one who transfers a cost is not in the position of the one who bears it. The one who can leave is not in the position of the one who cannot. These asymmetries do not necessarily arise because the principles were unjust. They arise between positions, after the principles are in place, and they can deepen while the principles themselves remain untouched.

This is why Boundaryism does not reject Rawls’s question. It asks the question that begins after Rawls’s has been answered. Not how a just order is chosen, but how that order is kept from crossing its own boundaries once it exists and once real people are standing somewhere inside it.

For Rawls, position is what justice must abstract away from in order to choose principles fairly. For Boundaryism, position is where legitimacy must be tested again and again after those principles begin to govern.

The veil asks how justice begins.

Boundaryism asks how legitimacy is maintained.
