The Positivismusstreit
Critical theory vs critical rationalism
Venue: Tübingen Conference of the German Sociological Association (October 1961); subsequent essays in *Der Positivismusstreit in der deutschen Soziologie* (1969).
The Frankfurt School and the Vienna-Circle heir confront each other on the methodology of social science.
At the 1961 Tübingen conference, Karl Popper presented "The Logic of the Social Sciences" and Theodor Adorno was the official respondent. Popper defended his critical rationalism — knowledge advances through bold hypotheses and falsification, social science is methodologically continuous with natural science, value-laden total critique of society leads to epistemic and political dead ends. Adorno (and later Habermas in subsequent exchanges) replied that Popper's methodology cannot grasp the totality of social formations whose ideological self-presentation constitutes part of their reality; critical theory must operate dialectically within and against its object. The conference itself was muted, but the published volume (1969) and the surrounding pamphlet war made it a defining moment of post-war German social philosophy. The label "Positivismusstreit" (positivism dispute) was imposed by the Frankfurt side; Popper rejected being labelled a positivist, and the disagreement was substantively about totalising vs piecemeal critique as much as about method.
Historical Context
Germany in 1961 was eight years post-Adenauer-era reconstruction; the student movement was nascent. The Frankfurt School (Adorno, Horkheimer, Marcuse) was the dominant intellectual tradition of the West German left; Popper, an Austrian exile, had defended an alternative reformist liberal position from the LSE.
Parties
Knowledge advances by bold conjecture and falsification, in social as in natural science. Piecemeal reform is the politically responsible alternative to revolutionary holism; total critique of "society as a whole" is methodologically vacuous and politically dangerous.
Key arguments
- Falsifiability as the criterion of scientific status; social-science theories must yield testable predictions.
- Methodological individualism: social phenomena are explained by individuals' beliefs, desires, and decisions interacting under institutional constraints.
- Open society: piecemeal social engineering responsive to discovered failures, against utopian holism.
- Historicism (the doctrine that history has discoverable laws of development) is empirically false and politically corrosive.
Popper's methodology cannot grasp social formations whose ideological self-presentation is part of their reality; critical theory must operate dialectically within and against its object. Social science divorced from totalising critique normalises the irrationality of existing arrangements.
Key arguments
- Society as totality: relations among individuals are mediated by structures that cannot be analysed piecemeal without losing their character.
- Ideology: the appearances society produces of itself are part of what social theory must penetrate, not data to be taken at face value.
- Negative dialectic: the critical task is to expose the contradictions of the existing order, not to construct positive predictions falsifiable within it.
- Popper's "open society" is the form ideology takes in late capitalism; pretending to neutrality is the most effective form of partisanship.

Verdict in retrospect
No reconciliation. Popper's critical rationalism shaped the philosophy of social science in the analytic tradition (Lakatos, Hacking — though with increasing nuance); critical theory shaped continental social philosophy (Habermas's 1970s communicative-action programme, Honneth, the broader Frankfurt tradition). The deeper question — whether social science can be methodologically continuous with natural science, or requires its own dialectical-hermeneutic methodology — remains contested.
