Dialectic of Enlightenment (German: Dialektik der Aufklärung) 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 (German: Philosophische Fragmente).
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 Enlightenment. They argue that its failure culminated in the rise of Fascism, Stalinism, the culture industry and mass consumer capitalism. Rather than liberating humanity as the Enlightenment had promised, they argue it had resulted in the opposite: in totalitarianism, and new forms of barbarism and social domination.
