Foucault: Power and Knowledge

When we think of power our eyes usually turn upwards. The head of state, the minister, the boss, the commander, the school principal, the head of the family… We look for an explicit relation in which one commands and another obeys. This view is not wrong but it is incomplete. For a significant part of the decisions that shape our lives does not arrive as a direct order. It works through files, examinations, diagnoses, performance measurements, statistics and descriptions of behaviour deemed “normal.” Nobody tells us openly to “be this kind of person,” yet we learn which traits count as successful, healthy, trustworthy or dangerous.

Michel Foucault’s thought on power and knowledge looks precisely into this invisible field. It shows that knowledge does not merely explain the world neutrally but is intertwined with practices that classify people and render them governable. This does not lead to an easy conclusion such as “science is a lie” or “all knowledge is propaganda.” It asks a harder question: within which relations of power do the institutions, measures and forms of expertise that allow something to count as knowledge operate?

Power is not only a hand that forbids

In the traditional image of power the sovereign says “do not,” the law draws a limit and punishment stops the disobedient. Foucault emphasises that modern power does not only prohibit; it also produces. It produces forms of behaviour, identities, fields of expertise and descriptions of the normal human being. School does not merely transmit knowledge; it turns the student into a particular subject through marks, attendance, attention and discipline. The hospital does not merely treat; it constitutes the body as a case that can be observed, compared and recorded. The prison does not merely confine; it makes the criminal into a personality type to be examined and corrected.

It cannot be said that these institutions serve no function. Education, treatment and security are real needs. Foucault’s contribution is to let us see how power works even inside good aims. A practice is not neutral because it is useful. While the patient’s recovery is sought their word may become unimportant; while the student’s development is measured they may be forced into a single pattern of success.

Power is therefore not an instrument possessed only by ill-intentioned people. It circulates in rules, in the arrangement of space, in who speaks and who listens, and in which knowledge counts as worth recording. Even if the director changes, the system can produce the same behaviour. Attributing the problem only to a “bad person” cannot explain why the same relation continues after the person is replaced.

The file does not only describe us; it constitutes us

Ever more records are kept about the modern individual. School marks, medical history, credit score, work performance, criminal record, online behaviour and purchasing habits accumulate in different systems. Each of these says something about us. But it does not merely reflect our present personality; by determining which roads open and close before us, it shapes us.

When a student is classified early as “unsuccessful,” an employee as “low-performing” or a neighbourhood as “risky,” these definitions affect later decisions. Fewer opportunities, closer surveillance or lower expectations can produce results that appear to confirm the first classification. Measurement does not merely record reality; it becomes part of reality. The language of the file can become more powerful than the person’s own story.

Today algorithmic scoring makes this relation still less visible. Sometimes even the person taking the decision cannot fully explain why a loan application, a job advertisement or a piece of social media content was filtered out. “The system calculated it this way” ends the discussion. The old bureaucrat’s prejudice could be criticised; a mathematical model, appearing objective, can repeat the same prejudice on a wider scale. Knowledge turning into numbers does not abolish its political consequences.

Who sets the measure of the normal?

For Foucault one of the important fields of the power–knowledge relation is normalisation. People are not divided only into legal and illegal; they are subjected to continuous gradations such as healthy–ill, industrious–lazy, compliant–problematic, safe–risky. Some of these comparisons answer real needs. Measurement is required to recognise an illness or to see where a student needs support. The problem is when the historical and social character of the measure is forgotten and it becomes the description of the one correct human being.

The word normal often carries at once the average and what ought to be. The behaviour of the majority becomes a moral measure. Whoever is different is not merely rare but may be considered in need of correction. Thus power works in our self-assessment before any punishment. When we cannot reach the standard body, productivity, relationship or success, we feel deficient.

On social media this normalisation is not carried out only by the state or an expert institution. Millions of people measure one another through likes, follows and comments. As certain faces, homes, relationships and ways of working are repeated, the measure of the desirable life is established. No one forces us into that mould; we compare, arrange and present ourselves voluntarily.

Alert to the politics of knowledge, not against knowledge

Readings of Foucault are sometimes pulled towards a dangerous shortcut: since knowledge is related to power, all truths are equally suspect. This interpretation puts evidence-based knowledge on the same level as invented claims. Yet questioning the institutional conditions of knowledge is not saying there is no truth. On the contrary, it requires examining more carefully how a claim was produced, by whom it was checked and how error is corrected.

Research showing a medicine’s effect is not the same as an advertising text. But which question the research asked, whom it sampled, who financed it and how the results were used remain open to discussion. Trusting scientific method is not the same as placing scientists beyond social oversight. Criticism is not to abolish expertise but to make expertise accountable.

Access to knowledge also matters here. Technical language is used not only to express a complex reality but sometimes to close the field of decision. People being able to understand their own health, environmental or work data does not mean having knowledge equal to an expert’s; it is the condition of being able to say something meaningful about their own lives.

If power is everywhere, where is resistance?

When we stop seeing power only at the top, the first reaction may be pessimism. If it operates in school, hospital, language, the body and our own thought, how shall we escape it? Foucault’s approach is not an account of a closed system in which power controls everything. Wherever power stands within a relation, there is also the possibility of resisting, reversing and using otherwise.

Learning the name of a classification does not mean being condemned to it. People can refuse the identities pinned on them, redefine them, or turn them into instruments of solidarity. Patients can demand participation in medical decisions, workers can question performance measures, students can open the single form of learning to debate. Resistance is not only marching on the palace; it is intervening in the small measures that define our lives.

Foucault does not show us a hidden centre of power and hand us a recipe for destroying it. He does something more uncomfortable: he forces us to look for the traces of power in our own well-meaning institutions, forms of knowledge and habits. This view provides no certain answer but grants an important attentiveness. When someone tells the “truth” about us, we begin to ask not only whether it is true but what authority over our lives that truth produces.
