Introduction

The twentieth century witnessed profound transformations in the discipline of Political Science as scholars increasingly questioned the assumptions, methods, and objectives of traditional institutional and normative political analysis. Among the most influential intellectual developments were the Behavioural Approach and the Marxist Approach, which offered contrasting yet highly significant perspectives on the nature of politics, political inquiry, and the purpose of political knowledge. While Behaviouralism sought to transform Political Science into an objective, empirical, and value-neutral social science through the systematic study of observable political behaviour, Marxism viewed politics as an expression of historically determined class relations rooted in the material organization of society. Consequently, the two approaches differ not only in their theoretical assumptions but also in their methodologies, epistemological commitments, and conceptions of political reality.

The Behavioural Revolution, which emerged primarily in the United States after the Second World War under scholars such as Charles E. Merriam, Harold D. Lasswell, David Easton, Robert A. Dahl, Gabriel A. Almond, Sidney Verba, Herbert Simon, and Karl Deutsch, emphasized scientific methods, quantification, hypothesis testing, survey research, and empirical verification. Behaviouralists argued that Political Science should move beyond the formal study of constitutions and legal institutions to examine how individuals and groups actually behave within political systems. Their objective was to establish Political Science as an empirical discipline comparable to the natural sciences through rigorous observation, measurement, and theory building.

In contrast, the Marxist Approach, derived from the works of Karl Marx and Friedrich Engels and subsequently developed by Vladimir Lenin, Antonio Gramsci, Rosa Luxemburg, Georg Lukács, Louis Althusser, Nicos Poulantzas, Ralph Miliband, and Erik Olin Wright, conceives politics as inseparable from the economic structure of society. Marxists reject the behavioural claim of value neutrality, arguing that political institutions, ideologies, and state structures primarily reflect underlying relations of production and class domination. Political analysis therefore requires historical investigation, dialectical reasoning, and critical examination of capitalism rather than merely describing observable behaviour.

These approaches represent fundamentally different conceptions of Political Science. Behaviouralism seeks explanatory generalizations through empirical research and methodological individualism, whereas Marxism emphasizes historical materialism, structural analysis, and normative commitment to emancipation from exploitation. Nevertheless, both approaches have profoundly shaped modern political inquiry. Behaviouralism introduced methodological sophistication and scientific research techniques, while Marxism expanded Political Science by incorporating economic power, ideology, class conflict, and structural inequality into political analysis.

This essay critically compares the Behavioural and Marxist approaches by examining their theoretical foundations, methodological orientations, principal assumptions, and contributions to Political Science. It argues that although Behaviouralism significantly advanced empirical research and methodological rigor, its neglect of structural inequalities and normative concerns limited its explanatory capacity. Conversely, Marxism provides a powerful framework for analysing power, class, and ideology but is often criticized for economic reductionism and deterministic tendencies. Contemporary Political Science increasingly draws upon insights from both traditions in developing more comprehensive and interdisciplinary approaches to the study of politics.

The Behavioural Approach

Meaning

Behaviouralism emerged as a reaction against:

• Traditional institutionalism.
• Legal formalism.
• Normative political theory.

Its central concern is the scientific study of political behaviour.

David Easton described it as both an intellectual tendency and an academic movement aimed at making Political Science more scientific.

---

Theoretical Foundations

Behaviouralism rests upon several assumptions.

Empiricism

Political knowledge should be based upon:

• Observation.
• Experience.
• Verification.

Facts rather than speculation constitute scientific knowledge.

---

Positivism

Behaviouralists believe Political Science should emulate the natural sciences by identifying regularities through systematic research.

---

Individualism

Politics is understood through the behaviour of:

• Individuals.
• Groups.
• Voters.
• Leaders.
• Bureaucrats.

Institutions are analysed through the actions of their participants.

---

Value Neutrality

Influenced by Max Weber, behaviouralists distinguish:

• Facts.
• Values.

Scientific inquiry should remain objective.

---

Methodological Orientation of Behaviouralism

Behaviouralists emphasize:

• Quantitative methods.
• Surveys.
• Questionnaires.
• Interviews.
• Statistical analysis.
• Sampling.
• Hypothesis testing.
• Comparative research.

Major methodological characteristics include:

• Verification.
• Quantification.
• Regularities.
• Systematization.
• Interdisciplinary research.
• Theory building.

David Easton summarized these as the “intellectual foundation stones” of behaviouralism.

Major Contributors

Important behavioural scholars include:

• Charles E. Merriam
• Harold D. Lasswell
• David Easton
• Gabriel Almond
• Sidney Verba
• Robert Dahl
• Herbert Simon
• Karl Deutsch

---

Contributions of Behaviouralism

Behaviouralism transformed Political Science by:

• Making research empirical.
• Introducing scientific methodology.
• Expanding comparative politics.
• Encouraging survey research.
• Developing systems theory.
• Promoting political psychology.
• Integrating sociology, economics, and psychology.

It shifted attention from constitutions to actual political processes.

---

Limitations of Behaviouralism

Behaviouralism has been criticized for:

• Excessive quantification.
• Neglect of values.
• Methodological fetishism.
• Ignoring historical context.
• Limited concern for social justice.
• Weak policy relevance.

David Easton’s Post-Behavioural Revolution itself argued that Political Science should pursue relevance and action, not merely methodological sophistication.

---

The Marxist Approach

Meaning

Marxism views politics as an expression of:

• Material conditions.
• Class relations.
• Economic structures.

Politics cannot be understood independently of society’s mode of production.

---

Theoretical Foundations of Marxism

Historical Materialism

History develops through changes in:

• Productive forces.
• Relations of production.

Economic structures shape political institutions.

---

Dialectical Materialism

Social development occurs through contradictions.

Conflict drives historical change.

---

Class Struggle

Marx famously writes:

“The history of all hitherto existing society is the history of class struggles.”

Politics reflects conflicts between competing economic classes.

---

State Theory

The state is not neutral.

It functions primarily to preserve dominant class interests.

Engels called the state:

“A product of irreconcilable class antagonisms.”

---

Ideology

Political ideas often conceal economic domination.

The ruling class controls both:

• Material production.
• Mental production.

---

Methodological Orientation of Marxism

Marxism employs:

• Historical analysis.
• Dialectical reasoning.
• Structural analysis.
• Political economy.
• Class analysis.
• Critical theory.

Research seeks explanation rather than mere description.

Unlike Behaviouralism, Marxism explicitly acknowledges normative commitments.

---

Major Contributors

Major Marxist thinkers include:

• Karl Marx
• Friedrich Engels
• Vladimir Lenin
• Antonio Gramsci
• Rosa Luxemburg
• Georg Lukács
• Louis Althusser
• Ralph Miliband
• Nicos Poulantzas
• Erik Olin Wright

---

Contributions of Marxism

Marxism significantly enriched Political Science through:

• Analysis of class power.
• Study of ideology.
• Political economy.
• Imperialism.
• Capitalist state theory.
• Social movements.
• Revolution.
• Global inequality.

It integrated economics and politics.

---

Limitations of Marxism

Critics argue Marxism suffers from:

• Economic determinism.
• Class reductionism.
• Underestimation of political autonomy.
• Weak explanation of identity politics.
• Limited appreciation of liberal democracy.
• Failure of deterministic revolutionary predictions.

Contemporary politics involves multiple identities beyond class alone.

Behaviouralism versus Marxism

The contrast between the two approaches reflects broader philosophical differences.

Behaviouralism asks:

• How do people behave politically?

Marxism asks:

• Why do political structures exist as they do?

Behaviouralists prioritize:

• Method.

Marxists prioritize:

• Historical explanation.

Behaviouralism studies observable political processes.

Marxism studies underlying structural causes.

---

Contemporary Relevance

Modern Political Science increasingly combines insights from both traditions.

Behavioural techniques remain indispensable in:

• Electoral studies.
• Public opinion.
• Comparative politics.
• Political psychology.

Marxist analysis remains influential in studying:

• Global capitalism.
• Economic inequality.
• Corporate power.
• Labour politics.
• Neo-colonialism.
• Political economy.

Contemporary approaches such as Critical Political Economy, Neo-Marxism, Historical Institutionalism, and Comparative Political Economy frequently integrate empirical methods with structural analysis.

---

Critical Evaluation

Behaviouralism and Marxism represent two distinct but complementary traditions in Political Science. Behaviouralism revolutionized the discipline by introducing methodological rigor, empirical verification, quantitative analysis, and systematic theory building. It enabled Political Science to move beyond descriptive constitutional studies toward the scientific investigation of political behaviour. However, its commitment to value neutrality often resulted in insufficient attention to inequality, ideology, and the normative purposes of political inquiry.

Marxism, by contrast, offers a deeper structural explanation of politics by linking political institutions to economic organization, class conflict, and historical development. It reveals how power operates through ideology, property relations, and state institutions, thereby exposing dimensions of political life often neglected by behavioural research. Yet its tendency toward economic reductionism, its limited treatment of non-class identities such as gender, ethnicity, and religion, and its deterministic interpretations of historical change have attracted substantial criticism.

Rather than viewing these approaches as mutually exclusive, contemporary Political Science increasingly recognizes their complementary strengths. Behavioural methods provide robust empirical tools for analysing political behaviour, while Marxist theory supplies broader explanatory frameworks for understanding structural inequalities and historical transformations. Together they contribute to a richer and more comprehensive understanding of political reality.

Conclusion

The Behavioural and Marxist approaches represent two of the most significant intellectual traditions in the evolution of modern Political Science. Behaviouralism sought to establish the discipline as a scientific enterprise through empirical observation, quantification, hypothesis testing, and value-neutral inquiry, fundamentally transforming research methods and expanding the scope of comparative political analysis. Marxism, meanwhile, challenged conventional understandings of politics by emphasizing the centrality of economic structures, class conflict, ideology, and historical materialism, thereby introducing a critical perspective on power, domination, and social transformation.

Although each approach possesses important strengths and limitations, neither provides a complete explanation of political life in isolation. Behaviouralism excels in methodological precision but often neglects structural inequalities and normative concerns, whereas Marxism offers powerful explanations of systemic power yet sometimes underestimates institutional autonomy, cultural diversity, and political pluralism. The continuing vitality of Political Science lies in its capacity to synthesize empirical investigation with critical theoretical analysis. By combining the methodological innovations of Behaviouralism with the structural insights of Marxism, contemporary political inquiry is better equipped to explain the complex interaction between individual behaviour, institutional processes, historical change, and relations of power in an increasingly interconnected world.
