The Frankfurt School was an institute founded in Germany in the 1920s that included thinkers like Theodor Adorno, Max Horkheimer, Herbert Marcuse, and others. They critiqued concepts from the Enlightenment like rationality, progress, and domination of nature. They argued that the Enlightenment created its own "myths" and that modern society lives in an era of unfreedom and violence due to "instrumental rationality." They also critiqued mass culture and the culture industry, arguing it led to increasing uniformity and standardization of products that created artificial needs and passivity in individuals in order to reinforce the capitalist system.
