Dialectic of Enlightenment () is a work of philosophy and social criticism written by Frankfurt School philosophers Max Horkheimer and Theodor W. Adorno. The text, published in 1947, is a revised version of what the authors originally had circulated among friends and colleagues in 1944 under the title of Philosophical Fragments (). One of the core texts of critical theory, Dialectic of Enlightenment explores the socio-psychological status quo that had been responsible for what the Frankfurt School considered the failure of the Age of Enlightenment. Together with Adorno's The Authoritarian Personality (1950) and fellow Frankfurt School member Herbert Marcuse's One-Dimensional Man (1964), it has had a major effect on 20th-century philosophy, sociology, culture, and politics, especially inspiring the New Left of the 1960s and 1970s. Historical context One of the distinguishing characteristics of the new critical theory, as Adorno and Horkheimer set out to elaborate it in Dialectic of Enlightenment, is a certain ambivalence concerning the ultimate source or foundation of social domination. Such would give rise to the "pessimism" of the new critical theory over the possibility of human emancipation and freedom. Furthermore, this ambivalence was rooted in the historical circumstances in which Dialectic of Enlightenment was originally produced: the authors saw National Socialism, Stalinism, state capitalism, and culture industry as entirely new forms of social domination that could not be adequately explained within the terms of traditional theory. For Adorno and Horkheimer (relying on the economist Friedrich Pollock's thesis on National Socialism), state intervention in the economy had effectively abolished the tension in capitalism between the "relations of production" and the "material productive forces of society," a tension that, according to traditional theory, constituted the primary contradiction within capitalism. The market (as an "unconscious" mechanism for the distribution of goods) had been replaced by centralized planning. Because of this, contrary to Marx's famous prediction in his preface to A Contribution to the Critique of Political Economy, this shift did not lead to "an era of social revolution," but rather to fascism and totalitarianism. As such, traditional theory was left, in Jürgen Habermas' words, without "anything in reserve to which it might appeal; and when the forces of production enter into a baneful symbiosis with the relations of production that they were supposed to blow wide open, there is no longer any dynamism upon which critique could base its hope." For Adorno and Horkheimer, this posed the problem of
