When Classification Becomes Power: Foucault on Knowledge, Normalization, and the Making of Subjects

Part I —From Classification to the Individual

1. The Table Behind the Person

What happens when a way of organizing knowledge becomes a way of organizing people?

The question can be approached through one of the simplest operations of thought: classification. We classify in order to distinguish one thing from another, establish relations among things, and make a heterogeneous field intelligible. A table, taxonomy, or grid of categories can therefore appear to be a neutral device for arranging what is already there. Yet Michel Foucault's work invites a more difficult question: what becomes possible once a particular system of distinctions determines what can be recognized, compared, and named?

In The Order of Things, Foucault approaches this problem at the level of the historical conditions under which knowledge becomes possible. His famous discussion of Borges's imaginary Chinese encyclopedia exposes the strangeness of classification by making an apparently coherent ordering of things suddenly impossible to inhabit. The problem is not simply that Borges's categories are unusual. It is that classification depends upon an underlying space in which things can be placed alongside one another and recognized as belonging to a field of comparison. What appears to us as an intelligible order is therefore not simply a mirror of the world. It depends upon historically specific ways of making differences visible and relations thinkable.

This gives us a first sense of what classification does. It does not merely answer the question, What is this? It helps establish the terms in which such a question can be asked.

The consequences become more significant when the objects being classified are not plants, animals, or commodities, but human beings.

A person may be classified as healthy or ill, capable or incapable, normal or abnormal, criminal or law-abiding, successful or unsuccessful. Such categories do not merely describe differences. Once embedded in institutions, they can affect how a person is treated, what is expected of them, which interventions are considered appropriate, and how their conduct is interpreted.

This is where a question about the historical organization of knowledge acquires a practical dimension.

The issue is not simply that categories can be historically contingent. Foucault's analyses allow us to ask what happens when historically produced distinctions become part of the ordinary mechanisms through which individuals are observed, assessed, corrected, treated, educated, or excluded.

The movement of the argument can therefore be stated simply:

classification makes things intelligible;

classification of people makes individuals intelligible in particular ways;

and when such classifications become embedded in institutions, they can begin to organize conduct.

The problem is no longer only how a culture orders knowledge. It is what happens when that order enters social practices.

2. From Order to Classification

Foucault's analysis of classification in The Order of Things is not primarily an account of particular taxonomies. His deeper concern is with the historical conditions that make certain forms of ordering possible at all. The table is important because it represents a space in which differences can be distributed, identities established, and relations made visible. A classification works because the things classified can occupy positions within an intelligible field.

This point matters because it prevents us from treating categories as if they simply waited to be discovered. A classification does not necessarily invent the objects it names, but it determines how differences among them can be organized and rendered meaningful. The same phenomenon may therefore acquire different forms of intelligibility under different historical arrangements of knowledge.

Yet there is an important difference between classifying things and classifying people.

When a botanist places a plant within a taxonomic system, the classification primarily serves to organize knowledge about the plant. When an institution classifies a person, however, the category may become part of a practice directed toward that person. It can enter a network of decisions and procedures: admission or exclusion, treatment or non-treatment, advancement or failure, surveillance or release, intervention or neglect.

This does not mean that every classification of a person is necessarily oppressive, nor that every institutional category is simply an arbitrary invention of power. The more precise Foucauldian question is: What does a particular classification make possible?

A diagnosis can make treatment possible. A school assessment can influence educational placement. A criminal classification can affect surveillance and punishment. A psychiatric category can place an individual within a particular institutional field. A performance rating can influence promotion or dismissal.

The category therefore does something beyond naming.

It places the individual within a field of differences in which particular responses become intelligible.

This is where the historical organization of knowledge begins to approach the question of power. Knowledge does not become power simply because someone possesses information about another person. The relation becomes more concrete when knowledge is incorporated into practices through which individuals are observed, compared, evaluated, and acted upon.

A useful distinction can be made here between three levels, without treating them as fixed Foucauldian categories:

epistemic classification makes something intelligible;

normative classification relates differences to a standard;

institutional classification places an individual within practices that can respond to those differences.

The three can overlap. Indeed, Foucault's analyses become particularly revealing precisely where they do.

This is why the question of the norm becomes so important. A classification such as A and B merely establishes a difference. But once individuals are compared against a standard of what counts as normal, healthy, capable, productive, or acceptable, difference acquires another dimension.

The issue is no longer simply:

How are these individuals different?

It becomes:

How does each individual stand in relation to the norm?

This seemingly small shift transforms classification into a practice of comparison.

And comparison opens the way to judgment.

3. From Difference to Norm

The concept of normalization allows Foucault to analyze a form of power that does not depend primarily on spectacular acts of prohibition or punishment. A norm provides a standard against which individuals can be compared, measured, differentiated, and assessed.

The difference is crucial.

A classification distinguishes:

A / B

A norm allows us to distinguish: closer to the norm / farther from the norm

The second arrangement creates a field of gradations. Individuals can occupy positions within it. They can be assessed, ranked, corrected, trained, or encouraged to move toward an expected standard.

This is one reason the examination is so important in Discipline and Punish. The examination combines observation with judgment. It makes the individual visible, but it also places that individual within a field of comparison. The student can be examined, the patient assessed, the prisoner observed, the worker evaluated. The individual becomes knowable through procedures that simultaneously produce information and establish differences.

The examination therefore has a peculiar double function. It is a procedure for acquiring knowledge about individuals, but it is also a mechanism through which individuals are positioned within a normative order.

This helps explain the importance of records, measurements, grades, reports, and other forms of documentation in disciplinary institutions. The individual is not merely seen; the individual is described, recorded, compared, and evaluated. Conduct can become a documented object of knowledge.

The result is a transformation in the status of the individual.

A person who enters an institution does not remain simply an undifferentiated individual. They can become a case: a particular instance within a field of comparison.

This is a significant development in Foucault's analysis. Power does not operate only by treating people as an anonymous mass. Disciplinary practices also individualize them. They distinguish one student from another, one patient from another, one prisoner from another, and produce detailed knowledge about each.

The individual is therefore caught between two movements.

On one side, classification places the person within a broader normative field.

On the other, examination produces increasingly detailed knowledge of that particular person.

The individual becomes both comparable and singular.

This is one of the paradoxes of disciplinary power. To govern individuals and populations effectively, it is useful to know people in their particularity. The more precisely a person can be observed and recorded, the more precisely that person can be compared with others and with an established standard.

The examination thus connects several operations that might otherwise appear separate:

visibility → observation → documentation → comparison → judgment

None of these operations, taken individually, is necessarily equivalent to domination. Observation can serve many purposes; documentation can preserve information; comparison can be useful. Foucault's point is more specific: when such procedures become systematically embedded in institutional arrangements, they can participate in disciplinary mechanisms that shape conduct.

This is why the norm matters so much. Without a standard, observation can tell us what someone does. With a standard, observation can tell us whether what someone does falls within, approaches, or departs from an expected range.

The individual thus becomes an object of knowledge in a very particular sense: not simply someone about whom information exists, but someone whose conduct can be located within an organized field of judgment.

At this point, the earlier question about the organization of knowledge has acquired a practical consequence. The table has not disappeared, it has become operational.

4. The Individual as a Case

Once an individual can be observed, compared, and evaluated, the person can also be entered into a record. This may seem like a minor administrative development, but for Foucault documentation is closely connected to the disciplinary production of individual knowledge.

The file, report, examination result, medical record, school assessment, or institutional dossier allows observations to persist beyond the moment in which they were made. The individual can now be followed across time, compared with previous performances, and placed within a cumulative history.

The person becomes a case.

This does not mean that the institution has simply discovered the individual's true identity. Rather, the individual becomes available for a particular kind of knowledge. Behaviors that might otherwise disappear into the ordinary flow of life can be isolated, described, recorded, and related to a standard.

A student's performance can be reduced to grades and comments. A patient's condition can be organized through symptoms and diagnoses. A prisoner's conduct can be documented through reports and observations. A worker's activity can become a series of evaluations.

The record creates continuity.

An isolated action can become part of a pattern.

A pattern can become a characteristic.

A characteristic can become a category.

And a category can influence how subsequent actions are interpreted.

This is one reason Foucault's account of disciplinary power cannot be reduced to the idea of an authority simply issuing commands. The individual is constituted as an object of knowledge through a network of relatively ordinary procedures: observation, examination, documentation, comparison, and judgment.

The resulting knowledge is not external to the exercise of power. Nor is power simply the application of knowledge produced somewhere else. The two become intertwined in institutional practices.

This is the significance of Foucault's notion of power-knowledge. The point is not merely that those in power use knowledge as a tool. Rather, particular forms of knowledge and particular relations of power can support and produce one another. The practices that make an individual knowable can simultaneously place that individual within a field in which certain actions become possible, legitimate, required, or prohibited.

The distinction is subtle but important.

It would be too simple to say: First the institution classifies the individual; then it exercises power over the classified person.

Foucault's analysis suggests a more complicated relation. The procedures through which the individual becomes an object of knowledge are themselves part of the operation of power. At the same time, the knowledge produced through those procedures can make further interventions possible.

The individual is therefore not merely under power in the sense of being subjected to an external force. The individual is also produced as a particular kind of object within practices of knowledge.

This brings us back to the problem with which we began.

A table initially seemed to be an instrument for ordering things. A classification appeared to be a way of making differences intelligible. But when classifications are connected to norms, examinations, records, and institutional practices, the consequences extend beyond knowledge.

The category can affect how the individual is seen.

The examination can determine how the individual is evaluated.

The record can preserve and circulate that evaluation.

And the resulting knowledge can shape what happens next.

The movement from The Order of Things to Discipline and Punish is therefore not a simple transition from “epistemology” to “politics.” It is a shift in the question we ask of classification.

At first: How does a historical order make differences intelligible?

Then: What happens when those differences become part of practices that act upon individuals?

The answer leads us toward normalization, discipline, and the production of subjects.

The table has become a procedure.

The category has become a judgment.

And the person has become a case.

Part II — From the Individual to Power

5. When Classification Becomes Normalization

The transition from classification to normalization is not simply a matter of adding a judgment to an existing category. It changes the function of difference itself.

A classification can distinguish one category from another. Normalization establishes a standard against which individuals can be measured. The question is no longer only where someone belongs, but how that person stands in relation to an expected way of behaving.

This distinction is central to Foucault's account of disciplinary power. The norm does not merely describe what most people happen to do. It can become a reference point through which conduct is evaluated and modified. Individuals are distributed around a standard, and their position within that distribution can become the basis for intervention.

The school provides an accessible example. A student can be described in terms of grades, attendance, behavior, participation, or performance. None of these measurements is inherently oppressive. Their significance changes when they form part of a system that distinguishes acceptable from unacceptable performance and attaches consequences to those distinctions.

The same structure can appear in other institutions. A medical examination can distinguish health from illness; a psychiatric assessment can distinguish recognized forms of conduct from those considered pathological; a prison can distinguish compliant from resistant behavior. In each case, observation acquires practical significance because it is connected to a standard and to an institutional response.

This is why normalization should not be understood simply as the imposition of an arbitrary rule. The more interesting Foucauldian question concerns the way standards become embedded in practices that appear ordinary, technical, or necessary.

Once a norm has been established, deviation can become an object of intervention.

The student who falls below an expected level may require remediation.

The prisoner whose conduct violates institutional expectations may require correction or increased surveillance.

The employee whose performance falls below a prescribed standard may be subjected to further evaluation.

The category does not merely describe the person. It helps organize what can happen to that person.

This is where the epistemic and practical dimensions of classification converge. The norm establishes a field within which individuals become comparable, while institutional procedures turn those comparisons into possible actions.

Foucault's analysis therefore complicates the familiar image of power as a force that primarily says no. Disciplinary power often works through smaller and more continuous operations: measuring, training, correcting, examining, recording, and comparing.

Its effectiveness depends partly on making differences calculable.

A person need not be publicly condemned as abnormal for a norm to shape their conduct. It may be enough to make performance visible, establish a standard, and provide mechanisms through which individuals are encouraged to adjust themselves.

This also explains why normalization can operate without a single person consciously designing the entire system. Norms can circulate through professional practices, institutional routines, administrative procedures, and forms of expertise. The power involved is therefore not adequately described as the intention of a particular authority.

What matters is the functioning of the arrangement.

A category becomes consequential when it can be connected to a practice.

A norm becomes disciplinary when it organizes comparison and correction.

And an examination becomes a mechanism of power when the knowledge it produces participates in this process.

The question has consequently shifted once more. We began by asking how classification makes the world intelligible. We then asked how individuals become objects of knowledge. We can now ask what happens when individuals begin to encounter themselves through these same distinctions.

6. When a Category Speaks for You

Classification can affect not only how a person is treated but also how that person's speech is received.

This point becomes especially important in Foucault's work on madness. The issue is not simply whether people classified as mad are prevented from speaking. They may speak extensively. The more difficult question is under what conditions their speech is recognized as meaningful, rational, authoritative, or true.

This is important because silencing does not always require the physical prevention of speech.

Someone can be allowed to speak and nevertheless fail to occupy a position from which their words are recognized as legitimate.

If a person has been classified as mad, for example, what they say may be interpreted through that classification. A statement about an experience, an institution, or another person can be heard not as a claim requiring consideration but as an expression of madness. The category therefore affects the conditions under which speech becomes credible.

This is one of the deeper implications of Foucault's concern with the historical division between reason and madness. The problem is not exhausted by asking whether people classified as mad have been treated badly. It also concerns the institutional and discursive procedures through which certain forms of speech are separated from the domain of legitimate reason.

The question can therefore be formulated more precisely: Who is allowed to count as a speaker whose words can constitute knowledge?

This takes us beyond the classification of individuals as such. We are now dealing with classifications of speech, speakers, and forms of discourse.

Not every statement enters a field of knowledge under the same conditions. The status of the speaker matters. So do the institutions in which speech occurs, the concepts available for interpreting it, and the procedures through which truth claims are assessed.

This is where Foucault's broader analysis of discourse becomes relevant. His concern is not simply with language as a system of signs but with the rules and practices that govern the production, circulation, and recognition of statements as meaningful or true within particular domains.

The category assigned to a person can therefore influence the status of their words.

A physician speaks differently from a patient within a medical institution.

A judge speaks differently from a defendant within a courtroom.

A teacher speaks differently from a student within a classroom.

An expert speaks differently from someone whose knowledge has not been institutionally recognized.

These differences do not mean that the first person is always correct or the second always mistaken. They indicate that speech occurs within structured relations of authority and recognition.

The point is especially clear when the category itself becomes an explanation for what someone says.

If a person's speech is interpreted through a diagnosis, the diagnosis may become more than a description of the person's condition. It can become part of the framework through which the speech is judged.

This is why it would be too strong to say that classification simply “silences” the subject. The more precise formulation is that classification can affect the conditions of audibility.

A person may retain the physical ability to speak while losing, or never acquiring, an institutional position from which their speech is treated as credible.

This adds another dimension to the earlier sequence:

visibility → classification → comparison → judgment

can become:

classification → interpretation → credibility → exclusion

The problem is therefore not only what happens to the classified individual as an object of institutional action. It is also what happens to their capacity to appear as a legitimate subject of knowledge.

And this leads to a still more unsettling possibility: the subject may eventually participate in the very process through which they are classified.

7. From Being Classified to Classifying Oneself

Disciplinary power does not depend entirely on an external authority constantly observing and correcting individuals. One of Foucault's important insights is that mechanisms of surveillance can be effective precisely when individuals begin to regulate their own conduct.

The Panopticon provides the architectural model for this possibility. Its significance is not simply that a guard can observe prisoners from a central position. More important is the asymmetry of visibility: the prisoner cannot know with certainty when they are being observed and must therefore behave as though observation were possible at any moment.

The consequence is a change in the relation between surveillance and conduct.

The individual begins to monitor the self.

This is why the Panopticon becomes more than a prison design in Foucault's analysis. It represents a principle of power in which continuous visibility can encourage individuals to regulate themselves.

The connection with classification is important. Once a norm has become available as a standard of comparison, individuals do not always need an external authority to tell them where they stand. They can evaluate themselves.

Am I performing well enough?

Am I healthy enough?

Am I behaving normally?

Am I productive enough?

Am I meeting the expected standard?

The questions are ordinary, but their significance depends upon the existence of standards against which the individual can measure the self.

Normalization can therefore become reflexive.

The person who has learned the categories does not merely encounter them from outside. They may begin to use them in interpreting their own conduct.

This is one reason Foucault's analysis cannot be reduced to a simple opposition between an oppressive institution and a passive individual. Power can operate through practices in which individuals participate, even when those practices constrain the field of possible conduct.

The individual becomes, in a sense, both the object and the agent of observation.

This does not mean that people are secretly responsible for their own subjection. Nor does it mean that external institutions cease to matter. Rather, disciplinary power can become more effective when the distinction between being observed and observing oneself becomes less clear.

The norm no longer needs to appear only as an external command.

It can become a criterion by which the individual interprets the self.

Here the movement from historical conditions of knowledge to social practice reaches its most intimate point. A system that began as a way of distinguishing and organizing can become part of the way a person understands who they are.

The table is no longer merely somewhere outside the individual.

Its categories can become part of the individual's own self-description.

8. What Classification Does

We can now see why classification occupies such an important place in Foucault's analyses, even though classification itself is never simply reducible to a single mechanism of power.

At the level of knowledge, classification makes differences intelligible. It establishes relations among things and provides a framework within which objects can be identified and compared.

When human beings become the objects of such practices, further consequences become possible.

Classification can make an individual visible.

A norm can make the individual comparable.

An examination can make the individual measurable and documentable.

An institutional category can make the individual actionable.

A discourse can affect how the individual is interpreted and heard.

And, under certain conditions, the norms produced through these practices can become part of the individual's own way of understanding the self.

This is the point at which different strands of Foucault's work converge without needing to be collapsed into a single theory.

The Order of Things asks how historically specific arrangements make objects of knowledge intelligible.

Discipline and Punish examines practices through which individuals are observed, examined, compared, and normalized.

His work on madness shows how divisions between reason and unreason can affect not only the treatment of individuals but also the status accorded to their speech.

Across these different investigations, the question is not simply who possesses power. It is how practices of knowledge and relations of power become intertwined in the production of objects, categories, and subjects.

This also changes how we should think about discrimination and exclusion. They do not always begin with an explicit declaration that someone is inferior or undesirable. They can emerge from apparently technical distinctions once those distinctions become connected to institutional decisions and unequal distributions of credibility, opportunity, treatment, or freedom.

The crucial issue is therefore not whether categories exist. Societies could hardly function without distinctions of some kind. The question is what a category does once it enters a network of norms, institutions, and practices.

A category can describe.

It can compare.

It can rank.

It can authorize intervention.

It can disqualify.

It can determine whose account receives attention.

It can even become part of the language through which a person understands themselves.

This is why the Foucauldian question is more demanding than simply asking whether a category is true or false.

We must also ask:

What does this category make possible?

What practices depend upon it?

Who gains authority from it?

Who becomes more visible through it, and who becomes less credible?

What forms of conduct become normal, and what forms become deviations?

These questions do not require us to assume that every classification is arbitrary or every norm oppressive. They require us to examine the historical and institutional conditions under which categories acquire practical force.

The problem that began with a table has therefore become a problem concerning the subject.

Conclusion — From the Table to the Subject

A table seems harmless. It places things beside one another, establishes distinctions, and makes an order visible. In The Order of Things, Foucault asks us to notice that such arrangements are historically specific rather than inevitable reflections of the world.

When the objects placed within these arrangements are human beings, however, something further can occur.

A classification can become a norm.

A norm can become a standard of comparison.

Comparison can become examination.

Examination can produce records and cases.

Records can enter institutional practices.

Those practices can affect how individuals are treated, judged, and heard.

And the categories through which individuals are known can eventually become categories through which they know themselves.

The significance of classification, then, lies neither in the mere existence of categories nor in the claim that categories are simply instruments of oppression. Its significance lies in the relations that form around them.

The Foucauldian question is therefore not merely: Who decided what is normal?

It is also: What becomes possible once something has been recognized as normal or abnormal?

A classification does more than place a person in a conceptual table. Under particular historical and institutional conditions, it can help determine how that person becomes visible, how they are evaluated, what can be done to them, and whether what they say will be heard as credible speech.

The movement from knowledge to power is therefore not a movement from one separate domain to another. It occurs when ways of knowing become embedded in practices that organize conduct and constitute subjects.

The table does not remain on the page.

It enters the institution.

And, eventually, it may enter the subject.
