Traditional theory, in Horkheimer's usage, is theory that takes the existing social order and its categories as given. Whether in the natural sciences, the social sciences, or philosophy in its positivist form, traditional theory treats its object as something to be described rather than transformed. It presents itself as objective and value-free — the neutral recording of facts — while concealing the social interests it serves. By accepting the categories of existing society as the framework within which inquiry proceeds, it systematically reproduces those categories and the power relations they encode.
Critical theory, by contrast, is reflexive: it includes in its object the social conditions that make theory possible and the interests it serves. It does not pretend to stand outside history and society as a neutral observer but acknowledges its own historical situatedness. What distinguishes it from mere political advocacy is its fidelity to the immanent contradictions of the existing order — the gap between what bourgeois society promises (freedom, equality, rational self-determination) and what it delivers (class domination, exploitation, administered unfreedom). Critical theory holds society to its own best standards.
The relationship between critical theory and transformative political practice is subtle. Critical theory is not a programme for political action and does not prescribe specific reforms. Its role is rather to maintain the consciousness of possibility — to insist that the existing order is not the only possible order, that its contradictions point toward forms of life that have not yet been realised. This makes critical theory permanently uncomfortable in both its academic and its political relations: it refuses the detachment of pure scholarship and the pragmatic compromises of direct political engagement.
"Traditional and Critical Theory" was published in the Zeitschrift für Sozialforschung in 1937. It is collected with Horkheimer's reply to his critics and several related essays in Critical Theory: Selected Essays (Herder and Herder, 1972). It remains the most accessible single-essay introduction to the Frankfurt School's theoretical programme.
