The history of sociology is often presented as the story of a new science born in nineteenth-century Europe to study industrialization, urbanization and capitalism. While this account is not wrong, it misses a deeper intellectual transformation. Sociology did not emerge from nowhere. It emerged from a long philosophical struggle over the nature of reality itself.
For more than two millennia, Western philosophy had been occupied with the question of being. The presocratics debated whether reality was change or permanence. Plato and Aristotle searched for stable structures beneath appearances. Medieval thinkers attempted to reconcile ontology with theology. Descartes shifted attention toward the knowing subject, while Kant transformed philosophy by asking not what reality is, but under what conditions reality becomes knowable. Yet by the nineteenth century, another question had become unavoidable. The rise of industrial society forced thinkers to ask not only what reality is, but what kind of reality society itself might be.
The crucial bridge between philosophy and sociology was Georg Wilhelm Friedrich Hegel. Kant had argued that human beings know the world through categories that structure experience. Hegel accepted this insight but introduced a radical historical dimension. To understand what is at stake here, it is useful to return briefly to Plato’s Allegory of the Cave. In Plato’s story, human beings mistake shadows for reality because they live imprisoned inside a world of appearances. Philosophy is the painful movement from illusion to truth, from the darkness of the cave toward the light of the Ideas.
Hegel inherits this Platonic intuition but transforms it historically. For Plato, truth lies outside the cave, in an eternal realm of Forms. For Hegel, truth does not exist outside history. It unfolds within history itself. Human beings do not escape the cave once and for all; rather, societies move through successive historical caves, each one offering a partial and limited understanding of reality. Ancient civilizations, religious worlds, monarchies, bourgeois societies and modern states are all stages in the development of Spirit (Geist), that is, of humanity becoming progressively conscious of itself.
Reality itself, Hegel argued, is not fixed. Institutions, moral systems, religions, political orders and forms of consciousness develop through time. History is not merely a sequence of events; it is the medium through which reality unfolds. In this sense, Hegel reintroduced movement into Western thought. The river of Heraclitus returned, but now it flowed through history rather than nature.
This is why Hegel’s idealism is so important for sociology. Ideas are not merely private thoughts inside individual minds. They become embodied in institutions, laws, religions, moral systems and political orders. Society is therefore not only a collection of individuals; it is a historical world of meanings and institutions through which human beings understand themselves. At the same time, this prepares the ground for the concept of alienation. If human beings create institutions, states, religions and economic systems, why do these creations so often appear as external powers standing above them? Hegel saw that human beings can become estranged from their own creations. The social world is produced by human activity, but it can confront human beings as something alien, objective and dominating.
Karl Marx inherited this historical vision while rejecting its idealist foundations. For Hegel, history was driven by the development of Spirit. For Marx, history was driven by material life. Human beings produce their world through labour, technology and economic relations, and these material activities shape politics, culture and consciousness. The factory, the mine and the city are not merely physical objects; they are embodiments of social relations. Marx therefore transformed the ontological question into a historical and material one. Reality is not simply discovered. It is produced. To understand society is to understand how human beings collectively create the conditions of their own existence.
Marx also transformed Hegel’s idea of alienation into a material and social diagnosis. Alienation is not simply the drama of Spirit becoming estranged from itself; it is the concrete condition of workers who produce wealth, commodities, technologies and institutions that then dominate them as capital, markets and state power. The products of human labour appear as independent forces standing above human beings. This insight would later nourish many theories of ideology and power. Friedrich Nietzsche would question how moral values conceal struggles over domination; Antonio Gramsci would show how ruling groups maintain power by shaping common sense and cultural consent; Michel Foucault would analyze how institutions, prisons, schools, hospitals and expert knowledge produce regimes of truth that define what counts as normal, rational, deviant or real. Later critical theory would extend this diagnosis through authors such as Theodor W. Adorno and Max Horkheimer, who analyzed the culture industry and the ways mass media could reproduce domination; Herbert Marcuse, who examined how advanced industrial societies produce conformity and false needs; Jürgen Habermas, who focused on communication, the public sphere and the colonization of the lifeworld; and Pierre Bourdieu, who showed how domination is reproduced through habitus, cultural capital and symbolic power. In this sense, the cave did not disappear with modernity. It became social. The shadows on the wall became institutions, ideologies, categories, markets, media systems, bureaucracies and forms of symbolic power.
Émile Durkheim approached the same problem from a very different angle. Whereas Marx focused on production and conflict, Durkheim was concerned with social order. Influenced by Kant’s concern with categories and by Auguste Comte’s vision of a scientific study of society, Durkheim argued that society possesses a reality of its own. Language, religion, law and morality are not reducible to individual preferences. They exist before us, shape our behaviour and continue after we disappear. Society, in other words, is not merely the sum of individuals. It is an emergent reality with its own properties. If Marx asks how society is produced, Durkheim asks how it holds together.
The third great founder, Max Weber, was dissatisfied with explanations that reduced society either to material structures or to collective forces. Drawing on the historicist tradition of Johann Gottfried Herder (known for arguing that each people, culture and historical epoch must be understood in its own context) and Wilhelm Dilthey (known for distinguishing the human sciences from the natural sciences through the idea of understanding lived historical experience), as well as the neo-Kantian philosophy of Heinrich Rickert and Wilhelm Windelband, Weber argued that social reality must also be understood through meaning. Human beings do not merely react to economic pressures or social norms. They interpret the world and act according to the meanings they attribute to it. The task of sociology is therefore not only to explain social phenomena but to understand them. This is the significance of Weber’s concept of Verstehen. Society is not simply produced or imposed; it is interpreted.
What is striking about these three founders is that each offers a different answer to the same underlying ontological question. Marx sees society as a historical and material reality structured by labour and conflict. Durkheim sees it as a collective reality that exists beyond individual consciousness. Weber sees it as a meaningful reality constituted through interpretation and action. Together, they transform the ancient philosophical question of being into a modern question about social existence.
The twentieth century would expand these insights in multiple directions. Alfred Schutz brought Husserl’s phenomenology into sociology, examining how social reality emerges through everyday experience. Martin Heidegger challenged the image of the detached observer and argued that human beings are always already immersed in a world of practical relations. Jean-Paul Sartre explored the tension between social structures and human freedom. Later, symbolic interactionists such as George Herbert Mead, Herbert Blumer and Erving Goffman examined how social reality is continuously produced through interaction. This tradition was especially powerful because it showed, through concrete empirical examples, how identities and meanings are made in everyday situations. Mead’s theory of the self explained how individuals become social beings by learning to see themselves from the standpoint of others. Goffman’s studies of face-to-face interaction showed how people perform roles, manage impressions and sustain fragile social situations, as in his analyses of everyday encounters, stigma and total institutions. Harold Garfinkel’s breaching experiments made this even more visible: by deliberately violating ordinary expectations, such as treating a casual family conversation as if it were a formal interview, he showed how much invisible work is required to maintain the appearance of social order. This connects directly with Heidegger’s analysis of breakdowns in everyday life. Just as a hammer or a cup becomes visible when it breaks or spills, social norms become visible when they are violated. If Heidegger revealed the invisible ontological infrastructure of practical action, Garfinkel revealed the invisible social infrastructure of everyday interaction. Later, labeling studies such as Howard Becker’s work on deviance showed that people do not simply become “deviant” because of an intrinsic quality of their actions, but because social groups define, label and react to certain behaviours as deviant.
Critical theorists investigated how power and domination shape everyday life. They studied, for example, how mass culture can produce conformity, how bureaucratic rationality can limit freedom, how capitalism creates false needs, how communication can be distorted by power, and how education, taste and culture reproduce class inequality. Finally, Bruno Latour and actor-network theory dissolved the boundary between society and technology, arguing that reality emerges through networks that include not only humans but also objects, infrastructures, documents, algorithms and non-human entities.
Seen from this perspective, sociology appears as something more than a social science. It becomes one of the great ontological projects of modernity. The ancient philosophers asked what reality is. Sociologists asked what kind of reality society is. Their answers differed, but all shared the conviction that the social world possesses a structure, a history and a logic that cannot be reduced either to nature or to individual minds. Sociology was born when the river of ontology entered the city.
