Theodor Adorno (1903-1969) was a cultural philosopher, sociologist, literary critic, and historian of music who, along with Max Horkheimer, Herbert Marcuse, and Erich Fromm, founded the Frankfurt School. Against Epistemology is one of his most important works. It inspired Habermas and Marcuse and continues to influence other eminent thinkers in philosophy and the social sciences today.

Against Epistemology is in essence a long essay against Western metaphysics or, as Adorno put it, "the lordship of the subject." Traditional philosophy, he noted, leads in practice to fascism. In this book, he combines analytic philosophy, social theory, and cultural criticism to try to show how epistemology betrays experience, using Husserl's work as a concrete model.
