When Theory Becomes Its Own Object

The risk of abstract normative models

Fa-Chiung Chang · 11 August 2026


Philosophy needs abstraction.

Without abstraction, thought remains trapped inside particular cases. We would have only examples, impressions, injuries, and reactions. We would not have concepts capable of travelling beyond one situation. A theory has to leave something out in order to see anything at all.

But abstraction has its own danger.

To gain generality, a theory temporarily removes certain features of reality. That is not a defect by itself. The question is whether the removed features are merely incidental, or whether they are part of the mechanism that makes the problem what it is. When the excluded variables determine the structure of the case, abstraction no longer clarifies reality. It creates a world in which the problem has become easier to solve.

Rawls’s veil of ignorance is one of the most influential abstractions in modern political philosophy. Its power is clear. By removing knowledge of one’s own place in society, it tries to free the choice of principles from the bias of personal advantage. It asks us to imagine a fair choice situation before we know whether we will be rich or poor, powerful or weak, advantaged or exposed.

That move has shaped generations of political theory.

But a larger question remains. When a theory keeps developing, supplementing, and refining itself in order to answer problems generated by its own abstraction, are we still using the theory as a tool for understanding reality? Or have we begun to maintain the theory as an object in its own right?

Abstraction as a tool

The problem is not that a theory is abstract.

All serious inquiry abstracts. Physics uses idealized bodies. Economics uses simplified agents. Philosophy uses stripped-down cases and imagined conditions. A model does not have to reproduce reality in full. It has to isolate what matters.

The question is therefore not:

Is this theory abstract?

The question is:

Has it abstracted away a variable that determines the result?

In some models, the omitted variable is harmless. A simple physical model may ignore friction because friction is not the object of inquiry. But political theory is different. Social position, power, dependence, institutional standing, and the distribution of costs are not always background noise. They may be the political problem itself.

If a theory constructs fair conditions of choice by removing history, power, interest, and social position, it must explain why these features are not constitutive of political justification. It cannot simply remove them and then treat the purified scene as if it had solved the problem from which those features came.

Otherwise the abstraction has not answered reality. It has changed the question.

The easier world

The veil of ignorance answers an important question:

What principles would people choose if they did not know which social position they would occupy?

This is a valuable question. It helps expose the unfairness of designing rules from within known advantage. If I do not know whether I will be strong or weak, rich or poor, healthy or dependent, I have reason to choose principles that are not tailored to my present benefit.

But the question also creates a special world.

It is a world of choosers without concrete histories, fixed interests, named institutions, accumulated advantages, or enduring relations of power. The model does not ask who is already in a position to define the options. It does not ask who will bear the costs if the chosen principles later fail. It does not ask who can reopen the arrangement once it has hardened into institutions.

Real institutions do not arise in a world like this.

They have authors. They have administrators. They have beneficiaries. They have those who bear their costs. They have people who can amend the terms and people who can only live under them. They have channels of revision, or the absence of such channels.

So a theory of political justification cannot stop at the question:

Were the principles chosen under fair conditions?

It must also ask:

After the principles are formed, who has standing to alter the terms under which others live?

If that second question is missing, the theory may have explained fairness in the choice situation while leaving legitimacy in institutional life untouched.

Development and preservation

Every important theory develops.

No theory is complete at the moment of its first formulation. Objections reveal ambiguities. New cases expose limits. Later writers clarify, extend, and repair. There is nothing suspicious about this. A theory that cannot grow is not alive.

But there are two different kinds of development.

The first is expansion. A theory discovers implications that were already latent in its structure. A concept is clarified. A principle is applied to a new domain. A distinction becomes sharper. The theory becomes more useful because it becomes more precise.

The second is preservation. A theory meets a difficulty that its original structure cannot handle, and new conditions are added in order to protect that structure from collapse.

The pattern is familiar.

The original model says: A can generate justification.

The objection says: A is not enough.

The reply adds B.

Another objection appears.

The reply adds C.

The problem is not that B or C are false. They may be intelligent, plausible, even necessary. The problem is whether they deepen the original theory or quietly perform work that the original model claimed it could do on its own.

At that point, the question changes. We should no longer ask only whether the later additions are defensible. We should ask whether the original model still has the explanatory authority it was taken to have.

If the model repeatedly needs other conditions to supply what its central abstraction removes, then the abstraction may not be a route to the problem. It may be a way around it.

When theory becomes its own object

Once a theory becomes influential, a second phenomenon appears.

Scholars begin to work inside the theory. They examine its concepts, compare interpretations, defend one version against another, solve internal tensions, and propose refinements. This is often valuable. Philosophy needs slow distinctions and disciplined interpretation.

But there is a risk.

A theory can shift from being a tool for understanding reality into being an object whose internal coherence becomes the main thing to be protected.

The cycle then becomes self-sustaining.

The theory generates a difficulty.

Research solves the difficulty.

The solution generates a new difficulty inside the theory.

More research solves that.

Eventually, enormous energy is spent maintaining a conceptual system rather than increasing our understanding of the world the system was meant to illuminate.

A large scholarly tradition proves that a theory has influence. It does not prove that the theory still captures the decisive variables of the problem. A theory can be academically productive precisely because it generates internal puzzles. That productivity is not the same as explanatory necessity.

The question is not whether the tradition is sophisticated. It is.

The question is whether the sophistication still serves the reality that made the theory matter.

Normative ideals and practical authority

Normative theory is indispensable.

Societies cannot live by facts alone. We need standards for saying that an arrangement is unjust, that a burden is wrongly imposed, that a rule should not be accepted merely because it exists.

But a normative theory must face a question about its own force.

Where does its normativity enter the world?

If a theory offers only an ideal standard, it can criticize reality from a distance. That is a legitimate task. But if it claims to explain the legitimacy of real institutions, it must face the structure through which institutions are made, maintained, and reopened.

It must ask:

Who forms the rules?

Who describes the options?

Who prices refusal?

Who bears the consequences?

Who can force revision when the arrangement fails?

A theory may stand above reality in order to judge it. But it cannot flee reality and still claim authority over it.

The difference matters because ideal choice and practical authority are not the same relation. A principle may be chosen without bias in an imagined situation and still leave unanswered the question of who, in actual institutions, has the power to define the terms under which others live.

Knowledge is one dimension. Exposure is another. A model that operates by removing knowledge does not thereby create a relation between rule-makers and cost-bearers. It may correct partiality in imagination while leaving insulation intact in practice.

The limit

The real issue is not whether we should have abstract theories.

Without abstraction, philosophy would disappear.

The issue is whether abstraction continues to serve reality, or whether reality is gradually asked to serve the abstraction.

A powerful theory should be capable of being reopened by the world it claims to explain. It should not only describe how a fair arrangement might be imagined. It should also help us see what happens when that arrangement produces costs, hardens into institutions, and confronts those who did not define its terms but must live under them.

The value of theory does not lie in creating a world that can be perfectly solved.

It lies in helping us understand the world that cannot be abstracted away.
