The study of political science centres on the distribution, exercise and consequences of power within societies and institutions. Steven Lukes’ influential framework, first set out in his 1974 work and revised in 2005, provides a particularly useful lens for understanding why power remains central to the discipline. From a sociological perspective, politics cannot be reduced to observable decision-making alone; it also encompasses the ways in which agendas are shaped and preferences themselves are formed. This essay outlines Lukes’ three-dimensional model, demonstrates its application to political analysis, and considers the implications for sociological understandings of authority and inequality.
Lukes’ Three Dimensions of Power
Lukes distinguishes between one-, two- and three-dimensional views of power. The one-dimensional view, associated with pluralist theorists such as Dahl, defines power as the ability to prevail in open conflicts over decisions (Lukes, 2005). The two-dimensional view, drawing on Bachrach and Baratz, extends the analysis to agenda-setting: power is also exercised when certain issues are kept off the political agenda altogether (Lukes, 2005). The three-dimensional view, Lukes’ own contribution, further includes the capacity to shape people’s wants so that they do not recognise conflicts of interest. This ideological dimension reveals power operating through socialisation, media influence and cultural norms. Each dimension moves analysis beyond visible behaviour to the structural and ideational conditions that sustain relations of domination.
The Centrality of Power in Political Science
Political science investigates how collective decisions are made and enforced, a process that necessarily involves power. Without a concept of power, the discipline would lack a coherent way to explain why some groups secure favourable outcomes while others do not. Lukes’ framework underscores that power operates at multiple levels simultaneously. In legislative settings, for example, observable voting records capture only the first dimension; the prior exclusion of radical proposals from debate illustrates the second; and the widespread acceptance of market-oriented policies as inevitable may reflect the third. Because political outcomes are shaped by all three processes, any comprehensive analysis must engage with power in its fullest sense. Indeed, classic definitions of politics as “who gets what, when, how” already embed assumptions about the unequal capacity of actors to determine distribution (Lasswell, 1936).
Sociological Implications and Limitations
Sociologists extend Lukes’ insights beyond formal state institutions to everyday social relations, including family, education and workplace hierarchies. The three-dimensional view, in particular, aligns with sociological concerns about ideology and hegemony, showing how dominant beliefs can mask structural inequalities. However, the approach is not without limitations. Critics note that Lukes’ emphasis on “real interests” risks introducing normative judgements that are difficult to verify empirically (Lukes, 2005). Furthermore, contemporary networked forms of governance and digital media complicate the identification of clear agenda-setters. Despite these challenges, the model retains value because it directs attention to the least visible mechanisms through which advantage is preserved. By integrating Lukes’ dimensions with sociological concepts such as Bourdieu’s symbolic power, analysts gain a more nuanced account of how consent is manufactured across different social fields.
Conclusion
Power is central to political science because it constitutes the very medium through which decisions are reached, agendas controlled and preferences shaped. Lukes’ three-dimensional model supplies a systematic means of capturing these processes, bridging institutional analysis with broader sociological questions of inequality and consent. While the framework requires careful application and awareness of its normative assumptions, it remains an essential tool for students seeking to understand why certain political arrangements persist and others are contested. Recognising the multiple faces of power therefore enhances both the explanatory reach and critical edge of political enquiry.
