Twentieth Century Insights on Power and Society

When we think about who holds power in society, the instinct is often to point to the government – the laws it passes, the force it commands, the decisions it makes. But twentieth-century sociologists pushed back hard against this instinct. Their core argument was straightforward: power is not concentrated in a single institution. It is distributed across the many organs that make up a functioning society. Understanding this idea – and why it matters – requires a close look at thinkers like Robert M. MacIver, along with his contemporaries who mapped the terrain of power from very different angles.

Who was Robert M. MacIver and why does he matter?

Robert Morrison MacIver (1882-1970) was a Scottish-born sociologist and political scientist whose work became foundational to how we understand the relationship between the state and society. Educated at the Universities of Edinburgh and Oxford, he taught at the University of Toronto before moving to Columbia University, where he served as Lieber Professor of Political Philosophy and Sociology from 1929 to 1950. He was elected president of the American Sociological Society in 1940 and authored more than fifteen books spanning sociology, political theory, and governance.

What made MacIver exceptional was his insistence on conceptual precision. At a time when many theorists blurred the line between the state and society – or treated them as the same thing – MacIver carefully distinguished between them. This distinction was not just academic. It had direct consequences for how we understand power, authority, liberty, and democratic governance.

The core distinction: state vs. society

MacIver’s most influential contribution to sociological theory was his clear separation of the state from society. For many thinkers before him – particularly in the Hegelian tradition – the state was treated as the supreme expression of social life, even as something approaching a moral absolute. MacIver rejected this emphatically.

In his view, society is the web of social relationships – a vast, organic network of human connections that includes family ties, economic exchanges, religious communities, cultural traditions, and moral codes. Society is natural, broad, and pre-political. It encompasses organized and unorganized groups alike and exists before any formal state structure is built around it.

The state, by contrast, is a specific, deliberate creation. Society precedes the state, embracing all associations, while the state organizes political life to secure specific ends. MacIver defined the state as an association that, acting through law and coercive power, maintains within a territorially defined community the universal external conditions of social order. It is one institution among many – not the whole of society, not even its governing form, but a functionally specialized organ tasked with maintaining law and political order.

Why conflating the two is dangerous

MacIver argued that identifying the social with the political produces the most serious conceptual confusion in the study of governance and human freedom. When the state is mistakenly treated as coextensive with society, it acquires a kind of moral totalness – a justification to reach into every dimension of human life. The sociologist in MacIver asserted itself whenever the concept of the state was detached from its social setting. His lifelong intellectual project was to resist this detachment and preserve the boundary between the political and the social, because that boundary is precisely what protects individual liberty.

In his landmark work Community (1917) and later in The Web of Government (1947), MacIver examined the varieties of political myth that had been used to inflate the state’s claims – comparing it to an organism, a super-mind, or a soul. He patiently dismantled each of these metaphors as inaccurate and humanly dangerous.

Power is not absolute – it is distributed

Central to MacIver’s sociology is the idea that power in society is not concentrated in a single place. It is spread across various societal organs – the family, the church, economic institutions, voluntary associations, cultural organizations, and the state itself. Each of these organs exercises a form of influence and authority within its own domain. The state holds coercive legal power, but it does not hold – and should not hold – all forms of social power.

MacIver’s seminal distinction between state and society, and his taxonomy of social structure, went beyond simple definitions. He developed an entire framework for understanding how different kinds of social institutions serve different purposes. Political power is one purpose; economic, educational, religious, and cultural purposes are others. No single institution, including the state, can claim to fulfill all of them.

MacIver viewed the state as a social institution that is necessarily interdependent with other institutions and the prevailing class system. This means the state does not operate in isolation – it functions within a broader social ecology. When it overreaches, ignoring the other organs of social life, it risks becoming authoritarian or dysfunctional.

The state as arbiter, not master

Rather than viewing the state as the supreme master of society, MacIver saw it as a kind of arbiter – a neutral authority that manages conflicts between competing social interests. In any complex society, different groups – workers and employers, religious communities and secular institutions, regional populations and national governments – have competing needs and values. The state’s role is to make binding decisions that keep these conflicts within manageable limits, not to impose a single vision of social life on everyone.

MacIver was equally firm that the state has limits. As the American Sociological Association notes, MacIver held that the state cannot be content with the mere maintenance of order alone, but must also function as a positive agency for economic regulation and for the development of personal and community resources – while still respecting the autonomy of other social institutions.

MacIver’s contemporaries: other views on power’s distribution

MacIver was not the only twentieth-century thinker grappling with questions of power and society. A group of Italian theorists – known as the Italian School of Elitists – offered a sharply different but equally important perspective. Gaetano Mosca and Vilfredo Pareto were among the first to stipulate that elite rule is inevitable, and to explore how dominant groups reproduce and transform their hold on power.

Gaetano Mosca and the ruling class

Mosca’s enduring contribution to political science is the observation that all but the most primitive societies are ruled, in fact if not in theory, by a numerical minority. He called this minority the political class – an organized group that gains power through superior organizational skills rather than hereditary right alone. Importantly, Mosca argued that because singular rule is practically unattainable, power is always vested in a small group acting with common interests, not in one absolute ruler. This is still, in its own way, a theory of distributed power – though distributed among an elite rather than across all societal organs.

Vilfredo Pareto and the circulation of elites

Pareto emphasized the psychological and intellectual superiority of elites, distinguishing between governing and non-governing elites. He argued that no elite rules forever – over time, one ruling group is replaced by another in what he termed the circulation of elites. Power shifts, but it never disappears; it simply moves from one organized group to the next. This insight challenged any naive belief in permanent revolutionary change or in the eventual disappearance of power hierarchies.

Robert Michels and the iron law of oligarchy

Robert Michels, a student of Max Weber, contributed the concept known as the iron law of oligarchy. Rather than merely positing the inevitability of elite domination, Michels tried to explain it by reference to the peculiar organizational features of modern politics. Even within democratic or socialist organizations, he observed, leadership tends to concentrate in the hands of a few. The very structure of large organizations – requiring specialization, coordination, and delegation – produces internal hierarchies that concentrate decision-making power.

What connects these thinkers?

Despite their differences, MacIver, Mosca, Pareto, and Michels all reject one common assumption: that political power can be absolute, total, or fully contained within a single institution. MacIver insisted that the state is one organ among many in a larger social web. The Italian elitists insisted that even within the state, power is never held by a single person or will – it is always distributed among an organized minority, contested by rival groups, and subject to eventual circulation or replacement.

Together, these twentieth-century theorists advanced a more realistic and sociologically grounded account of power. Power is not a switch that one actor controls. It is a dynamic, relational force – embedded in institutions, negotiated between groups, and shaped by the structure of society itself. The central argument shared by elite theorists was that only a small number of people in any organization can hold authority, and that their occupation of these positions automatically places them at odds with those subjected to it.

Why this still matters today

The questions these thinkers raised are far from settled. Modern democracies continue to wrestle with the proper limits of state power, the role of economic institutions in shaping political outcomes, and the tendency of organizations – public and private alike – to concentrate authority in small groups. The importance of studying sociology within politics has had recognition across figures from Mosca to Pareto, who recognized that politicians and politics do not operate in a societal vacuum.

MacIver’s insistence that society is more than the state, and that power operates through multiple societal organs, remains a crucial corrective. It reminds us that governance is not simply about who controls the levers of formal government, but about how authority, norms, economic resources, and cultural values interact across the whole fabric of social life. MacIver’s work addresses the ever-present tensions between liberty and authority, private interests and the common good – tensions that no amount of institutional design has ever permanently resolved.

What do you think? If power is genuinely distributed across multiple societal organs – the family, the church, the economy, the state – which of these organs do you think holds the most influence in contemporary society, and why? And given Michels’ iron law of oligarchy, is it possible for any large democratic organization to truly avoid the concentration of power in a small leadership group?
