Should the study of human society follow the same methods as the natural sciences, or does it require a fundamentally different approach? This question—the naturalism debate—has shaped the philosophy of social science since the late nineteenth century. Consider a social phenomenon like rising crime rates. A naturalist might seek causal laws linking crime to economic conditions, treating social facts as measurable variables. An anti-naturalist might instead ask how participants interpret crime, what meanings they attach to it, and how those meanings shape behavior. Neither approach is obviously complete, and the tension between them has generated a rich sequence of competing frameworks.
Interpretivism emerged in the 1890s as the first systematic anti-naturalist position. Its core claim is that social life is constituted by meanings, intentions, and self-understandings that cannot be captured by the causal laws of natural science. To study society, researchers must engage in Verstehen—interpretive understanding of the meanings actors attach to their actions. This framework, associated with Max Weber and later Alfred Schutz, insisted that social explanation requires grasping the subjective point of view. Interpretivism did not reject empirical rigor, but it argued that the object of social inquiry is fundamentally different from the object of natural inquiry.
At roughly the same time, Methodological Holism offered a different anti-naturalist path. Where interpretivism focused on individual meaning, holism argued that social phenomena must be explained by reference to social wholes—structures, institutions, or systems—that are not reducible to individual actions. Émile Durkheim’s study of suicide rates exemplified this approach: he explained a seemingly individual act through social facts like integration and regulation. Holism and interpretivism coexisted as rival anti-naturalist frameworks, disagreeing over whether the primary unit of analysis is the meaningful individual or the supra-individual structure.
Positivism entered the social sciences around 1900 as the naturalist counter-position. Drawing on the success of the natural sciences, early positivists like Auguste Comte and later the Vienna Circle argued that social phenomena can and should be studied through the same methods: observation, measurement, and the search for law-like regularities. Positivism rejected both interpretivism’s emphasis on subjective meaning and holism’s appeal to irreducible structures, insisting that all valid explanation follows the deductive-nomological model. For much of the twentieth century, positivism was the dominant framework in economics, psychology, and parts of sociology, setting the terms that later frameworks would challenge.
After World War II, Methodological Individualism refined the naturalist program while breaking with holism. Its central thesis is that all social phenomena must be explained in terms of individual actions, beliefs, and desires. Figures like Karl Popper and Jon Elster argued that holistic explanations are either metaphorical or reducible to individual-level mechanisms. This framework preserved positivism’s commitment to causal explanation but narrowed it: the proper unit of analysis is the individual, not the group. Methodological Individualism thus stood in direct opposition to Methodological Holism, while sharing interpretivism’s focus on individual agency—though without interpretivism’s insistence on interpretive methods.
Critical Theory, emerging from the Frankfurt School in the 1930s and gaining prominence after the war, offered a normative challenge to positivism’s claim of value-neutrality. Theorists like Max Horkheimer and Jürgen Habermas argued that social inquiry cannot be separated from ethical and political critique. Positivism, they claimed, reduces knowledge to technical control and ignores the role of power, ideology, and emancipation. Critical Theory absorbed interpretivist insights about meaning but added a critical dimension: understanding social life requires not just interpreting meanings but also exposing the conditions that distort them. This framework coexisted uneasily with both positivism and interpretivism, rejecting the former’s neutrality and the latter’s tendency to accept actors’ self-understandings at face value.
Social Constructivism, emerging in the 1960s, radicalized interpretivism by questioning the very distinction between the natural and the social. If all knowledge—including scientific knowledge—is socially constructed, then the natural sciences themselves are not a neutral benchmark. Peter Berger and Thomas Luckmann’s The Social Construction of Reality (1966) argued that social reality is produced through ongoing interactions and shared typifications. This framework narrowed the naturalism debate by undermining the idea that natural science provides a model independent of social processes. Social Constructivism did not reject empirical research, but it insisted that the categories and facts researchers use are themselves products of social activity.
Practice Theory, which gained traction in the 1970s, dissolved the long-standing opposition between individualism and holism. Instead of starting from either individual agents or social structures, practice theorists like Pierre Bourdieu and Anthony Giddens argued that the fundamental unit of social analysis is the practice—the routine, embodied, and often tacit activity through which social life is produced and reproduced. Practices are neither purely individual nor purely structural; they are the site where agency and structure meet. Methodologically, this means studying what people actually do in concrete settings, attending to the skills, habits, and material arrangements that sustain social order. Practice Theory thus absorbed insights from both interpretivism (meaning) and holism (structure) while rejecting the idea that either can be treated as foundational. It remains influential in anthropology, sociology, and science and technology studies.
Critical Realism, developed by Roy Bhaskar in the 1970s and widely adopted by the 1980s, offered a third-way ontology between positivism and interpretivism. Bhaskar argued that social structures are real but not directly observable; they exist as causal mechanisms that generate events. Unlike positivists, critical realists deny that explanation requires regularities—mechanisms can operate even when countervailing forces prevent observable patterns. Unlike interpretivists, they insist that structures have causal power independent of actors’ awareness. Critical Realism thus revived a form of realism about social entities while rejecting positivism’s empiricism. It directly opposed Social Constructivism’s tendency to reduce reality to discourse, arguing that social structures are both real and transformable.
Feminist Philosophy of Social Science, emerging around 1980, is a cross-cutting tradition that draws on multiple earlier frameworks while adding a distinctive gender lens. Feminist theorists like Sandra Harding and Donna Haraway argued that traditional social science has systematically excluded women’s experiences and perspectives, producing partial and distorted knowledge. This framework shares Critical Theory’s normative commitment to emancipation and Social Constructivism’s attention to how power shapes knowledge. But it goes further by insisting that the social position of the knower matters epistemically—standpoint theory holds that marginalized groups can have epistemic advantages. Feminist philosophy does not reject empirical methods but demands that researchers reflect on how gender, race, and other axes of inequality shape research questions, methods, and conclusions.
Social Epistemology of Science, which took shape in the 1990s, shifts the focus from the content of social theories to the institutional structures that produce and validate knowledge. Drawing on work by Helen Longino and Philip Kitcher, this framework examines how scientific communities organize themselves—how peer review, funding, publication, and collaboration shape what counts as evidence and theory. Social epistemology complements rather than replaces earlier frameworks: it does not take a direct stand on naturalism but asks how the social organization of inquiry affects objectivity and reliability. It connects to Feminist Philosophy by analyzing how institutional biases can exclude certain perspectives, and to Critical Theory by examining how power operates within knowledge-producing institutions. Today, social epistemology is a vibrant area that bridges philosophy of science, sociology of science, and science policy.
No single framework has won the naturalism debate. Instead, the field has become increasingly pluralist, with different frameworks dominating different disciplines. Economics and much of psychology remain broadly naturalist, often relying on methodological individualism and quantitative methods. Sociology and anthropology are more divided, with interpretivism, practice theory, and critical realism all active. Political science has seen a resurgence of naturalist approaches alongside critical and feminist alternatives. What the leading frameworks agree on is that social inquiry must be rigorous and empirically grounded. What they disagree on is what counts as evidence, whether explanation requires causal laws or interpretive understanding, and whether values can or should be excluded. This ongoing conversation, rather than any single resolution, defines the philosophy of social science today.
