Conflict theory rests on a concept it does not itself define adequately: power. This lesson takes it directly, because power is both the discipline's most-used word and its most contested one, and because there is an unusually clear structure to the argument.

The structure is a sequence of moves, each of which says: the previous account measures only the power you can see.

The first face: decision-making

What is right about it: it is checkable. It requires evidence. It refuses to infer power from position or reputation alone, and it produced a genuine finding — that different groups prevail in different domains, which the elite theorists' model did not predict.

What is wrong with it: it can only detect power that produces a visible contest. Everything that prevents a contest is invisible to it, and the next two moves are about exactly that.

The second face: non-decision-making

Peter Bachrach and Morton Baratz, "Two Faces of Power" (1962), made the first move.

How it operates, concretely:

Rules of procedure determine what is a proper subject for a body to consider. Agenda-setting determines what reaches the table and in what order. Anticipated reactions — the most common form — mean that a proposal is never made because everyone knows it would fail. Definitions of the possible rule options out as unrealistic before they are stated. And the threat of sanctions, which need not be issued to be effective.

The third face: shaping preferences

Steven Lukes, Power: A Radical View (1974), made the decisive move.

Beyond the three faces

Foucault (5.9) rejects the whole framework. Power for him is not something possessed by A and exercised over B; it is a relation dispersed throughout the social body, operating through discourse, classification, examination and self-regulation, and it is productive — it produces subjects, categories and knowledge rather than merely repressing. "Where there is power, there is resistance." The question is not who has power but how power operates, and the answer is: through the constitution of what counts as normal, true and possible.

Bourdieu (5.10) adds symbolic power: the power to impose categories of perception as legitimate, so that arbitrary distinctions are experienced as natural. Symbolic violence is the process by which the dominated accept the terms of their domination because those terms are the only ones available for thinking about it. This is close to Lukes's third face with a mechanism supplied — the habitus, formed by position, generating preferences that fit the position.

Michael Mann's The Sources of Social Power (1986–2012) distinguishes four networks — ideological, economic, military and political — that are not reducible to one another and that combine differently in different periods. It is the most substantial historical treatment, and its central methodological point is that power is not one thing.

Gramsci's hegemony (5.6) is the third face developed with a politics: consent won continuously in civil society, never total, requiring real concessions, and contestable.

And the "power to" tradition — Hannah Arendt, and Talcott Parsons, of all people — insists that power is not only domination but the collective capacity to act, generated when people combine. Arendt: "power corresponds to the human ability not just to act but to act in concert." This is a genuinely different concept sharing a word, and conflating them causes confusion.

The empirical difficulty, honestly

The three-faces framework is more useful analytically than it is tractable empirically, and this should be said.

The first face is measurable and captures the least. The second requires demonstrating that something was kept off an agenda, which usually means finding the comparable case where it was not. The third requires counterfactual claims about what people would want under conditions that do not obtain.

Which is why the best empirical work on power tends to be comparative and historical: Skocpol on revolutions, Mann on power networks, Steven Levitsky and Lucan Way on competitive authoritarianism, Gilens and Page on policy responsiveness (4.6.2, with its methodological disputes). The comparison supplies the counterfactual that a single case cannot.

And the practical rule for a reader: when someone claims power is operating, ask which face they mean and what evidence would show it. When someone claims it is not, ask whether they are only looking at the first.

Why it matters

It is the discipline's central concept, and this is the clearest map of it. Three faces, each detecting what the previous one misses, with a stated method and a stated difficulty for each.

It supplies a permanently useful question: not "who has power here?" but "which face is operating, and what would count as evidence?" Applied to a workplace, a family, a government or a market, it disciplines a word that is usually used loosely.

It shows a concept being properly contested. Lukes's second edition, conceding substantial ground and defending what remained, is a model of intellectual conduct — and a demonstration that "essentially contested" does not mean "impossible to reason about."

And it names the thing conflict theory needs and does not supply. Coser and Dahrendorf describe conflict; this lesson describes what determines its outcomes and, more importantly, what determines whether it occurs at all. The conflicts that do not happen are the ones that tell you most about a society, and only the second and third faces can see them.
