Political theory is not an easy or simple enterprise — it is, as John Plamenatz insists, “an elaborate, rigorous, difficult and useful understanding, as much needed as any of science.” The case for studying it rests on a foundational recognition: neither philosophy nor science holds a privileged cognitive status within political theory. All political philosophy makes claims about how the political world actually operates, claims that require empirical examination to sustain. All political science raises normative questions that a dedication to value-free explanation cannot dissolve. Political theory is necessary precisely because it refuses to let either philosophy or science off the hook.
Political Theory as Intellectual Activity: More Than a Discipline
Political theory is more than a discipline with a syllabus and a canon. It is an intellectual exercise, an activity — one that must function simultaneously as philosophy and as science. Dante Germino captures the spirit of this dual demand well. The political theorist, he argues, turns their back on “distortions, over-simplifications, sloganeering and demagoguery” and speaks out honestly on the perpetual problems confronting human existence in society. As philosophy, political theory will always attempt to find out the truth in every situation. As science, it will always attempt to reach the truth. The distinction is subtle but consequential: philosophy is the orientation toward truth; science is the method of arriving at it. Political theory requires both.
Plamenatz is equally clear about what political theory is not. It is not fantasy. It is not the parading of prejudices. It is not an intellectual game, and still less a form of “linguistic analysis.” These characterisations — which behaviouralists sometimes offered as defining the limits of political theory — Plamenatz regards as serious misunderstandings of what the enterprise actually does.
The Tasks Before Political Theory
As Science: Three Analytical Functions
David Held identifies three tasks that political theory must perform in its scientific capacity.
The first is to identify significant political variables and describe their mutual relations. This requires an analytic scheme — without one, political research is merely the accumulation of unordered facts. A theoretical framework renders research meaningful and allows facts to cohere into generalisations.
The second is to enable comparative research. When workers in a field share a common theoretical framework, the results of different research projects can be meaningfully compared, earlier conclusions can be verified or revised, and areas requiring further empirical work can be identified with precision. Without such a framework, findings accumulate in isolation, unable to speak to one another.
The third is to make research more reliable. A relatively consistent body of concepts disciplines inquiry — it constrains what counts as evidence, what counts as explanation, and what kinds of conclusions the data can support.
As Philosophy: Going Beyond the Present
Political theory’s philosophical tasks require it to go beyond what science alone can accomplish. The distinction here is not merely methodological but substantive. Science studies a phenomenon; philosophy understands it — and understanding requires situating the present in relation to both its past and its possible futures. Political theory cannot confine itself to the study of the status quo. It must ask not only what the present is but for what the present exists — a question that pushes it inevitably into normative territory.
Four Orientations of Political Theory
Contemporary scholarship has identified at least four distinct ways of understanding what political theory’s tasks actually are, each associated with a different intellectual tradition.
The normative orientation, associated above all with John Rawls, treats political theory as a branch of moral philosophy. Its task is not only to develop general principles for evaluating social structures but to design appropriate institutions, procedures, and policies for realising those principles. Bruce Ackerman’s Social Justice in the Liberal State (1980), Brian Barry’s A Treatise on Social Justice (1989), and Charles Beitz’s Political Theory and International Relations (1979) all work within this orientation, extending its reach from domestic to international contexts.
The contemplative and reflective orientation, associated with Charles Taylor (Philosophical Papers, 1985), Alasdair MacIntyre (After Virtue, 1981), and William Connolly (Political Theory and Modernity, 1988), treats political theory as primarily concerned with understanding human existence in general — not as a branch of moral philosophy, and not necessarily normative in its orientation. Its purpose is comprehension, not prescription.
The interpretive orientation, associated with Michael Walzer’s Spheres of Justice (1983), treats political theory as primarily concerned with articulating the self-understanding of a particular community. It is necessarily local in scope — what Walzer calls “municipal” — and interpretive in method. Universal principles are arrived at, if at all, by working through the specific rather than above it.
The exploratory orientation, associated with Richard Rorty’s Contingency, Irony and Solidarity (1989), insists that political theory should be tentative, conversational, open-minded, ironic, and sensitive — resistant to the foundationalist ambition that characterises both the normative and the interpretive traditions. Political theory, on this account, keeps the conversation going rather than settling it.
These four orientations are not always compatible. The tension between them — between the universalism of Rawls and the localism of Walzer, between the normativity of Barry and the irony of Rorty — constitutes one of the most productive fault lines in contemporary political thought.
The Significance of Political Theory: A Defence
The question of political theory’s significance became urgent in the mid-twentieth century, when behaviouralists declared much of the classical tradition intellectually bankrupt. The charge, as Plamenatz reported it, was blunt: “Political philosophy is dead, killed by the logical positivists and their successors who have shown that many of the problems which exercised the great political thinkers of the past were spurious, resting in confusions of sight and the misuse of language.”
Plamenatz’s response, in his essay “The Use of Political Theory,” identified five distinct uses that political theory performs — uses that no amount of empirical political science could replicate or replace.
Political theory is a serious intellectual activity. The need for rigorous reflection on the nature of political life, political values, and political institutions is, if anything, greater in modern conditions of complexity and ideological conflict than at any earlier point. The fact that it does not produce the same kind of knowledge as empirical theory does not make it less necessary.
Political theory is the study of values, norms, and goals. Empirical political science tells us how political systems work; political theory asks what they are for. These are different questions, and both require answers.
Political theory is the study of historically influential theories. The great texts of political theory — from Plato’s Republic to Rawls’s A Theory of Justice — have not merely described political life; they have shaped it. They have profoundly influenced how human beings understand themselves, their social arrangements, and their political possibilities. Studying them is not antiquarianism — it is understanding how political reality has been constructed.
Political theory has an element of socially conditioned ideology. This is Plamenatz’s most challenging claim. Political theories are not produced in a vacuum; they emerge from specific social contexts and carry ideological freight. But this does not disqualify them. Even the “illusions” that political theories sometimes propagate shape the course of social development. Without them, history would not have been what it is.
Political theory produces a coherent system of political principles. This, for Plamenatz, is the core function. Political theorists do not, like shopkeepers, “display a large variety of goods, describing them all accurately and leaving it to the customer to choose.” They produce a hierarchy of principles and try to explain how people should use them to make their choices. They are, in his memorable formulation, “not mere purveyors of ideas; they are the preachers and the propagandists.”
C. Wright Mills: Four Dimensions of Significance
C. Wright Mills, writing in The Marxists (1962), adds a sociological dimension to this defence. Political philosophies, Mills observes, “are intellectual and moral creations. They contain high ideals, easy slogans, dubious facts, crude propaganda, and sophisticated theories.” This complexity is not a defect — it is what makes them socially potent.
Mills identifies four dimensions of that potency. First, political theory is itself a social reality — an ideology through which institutions and practices are justified, attacked, and framed. It provides the phrases in which demands are raised, criticisms made, and policies, at times, determined. Second, it is an ethic — an articulation of ideals used in judging events, movements, and persons. Third, it designates agencies of action: it identifies not only where we want to go but who is to take us there and by what means. Fourth, it contains theories of man, society, and history — frameworks that tell us how society is constituted and how it works, and therefore where we stand and where we may be going.
This tension between Plamenatz’s focus on principled guidance and Mills’s focus on ideological function reflects a genuine ambiguity in political theory’s social role. In India, this ambiguity has played out with particular clarity. The political theory embedded in the Indian Constitution — drawing on liberalism, social democracy, and Ambedkar’s own anti-caste philosophy — has functioned simultaneously as principled normative framework and as contested ideological terrain. Debates over reservations, minority rights, and the scope of directive principles are not merely legal disputes; they are arguments conducted in the language that the constitutional framers’ political theory made available.
Why Study Political Theory? The Comprehensive Answer
Political theory explains, illuminates, understands, evaluates, enlightens, and alters. Each of these verbs does different work. Explanation accounts for political phenomena. Illumination reveals what explanation alone may leave in shadow. Understanding situates phenomena within larger wholes. Evaluation judges them against normative standards. Enlightenment transforms the understanding of those who engage with the theory. Alteration — the most ambitious function — changes political reality itself.
Political theory also contributes to the capacity of human beings to understand themselves, to transform themselves, and to take command of their own common affairs. It aims to comprehend the world in which it arises, identify its salient character, understand its crises, and assess the capacity to resolve them. This is not a modest ambition. It is, as Germino suggests, what makes political theory one of the most demanding and consequential intellectual activities available to us.
The behaviouralist challenge has not disappeared. Quantitative political science continues to produce genuinely important knowledge. But the post-2008 resurgence of inequality debates, the post-2016 crisis of liberal democratic legitimacy, and the post-2020 reckoning with structural racism have each demonstrated — once again — that empirical description without normative framework leaves political science unable to do its most important work: to tell us not only what is happening but what it means, and what ought to be done about it.
Key Takeaways
- Political theory is not an easy enterprise — it is elaborate, rigorous, difficult, and indispensable, combining the functions of philosophy (finding truth) and science (reaching truth).
- Neither philosophy nor science holds a privileged status within political theory; both are essential and neither can substitute for the other.
- As science, political theory identifies significant variables, enables comparative research, and makes inquiry more reliable. As philosophy, it goes beyond the status quo to ask what the present exists for.
- Four orientations define contemporary political theory: normative (Rawls, Barry), contemplative (Taylor, MacIntyre), interpretive (Walzer), and exploratory (Rorty).
- Plamenatz identifies five uses: serious intellectual activity, study of values and norms, study of historically influential theories, analysis of socially conditioned ideology, and production of a coherent system of political principles.
- C. Wright Mills adds four dimensions of political theory’s social significance: as social reality and ideology, as ethical framework, as designator of agencies of action, and as theory of man, society, and history.
- The behaviouralist declaration of political theory’s death was premature; the recurring crises of contemporary politics demonstrate that normative political theory is not merely academically valuable — it is politically necessary.
