Putting at work a negative pedagogy centered around learning from unlearning, problematizes and boldly challenges today's culturalist discourses, camouflaged racisms, and masked fascisms. Great critical theorists from Marx and Engels to Adorno and Horkheimer not only came from the margins but also stayed faithful to the plight of the marginalized. They refused to compromise about the struggle for equality and tried to universalize its emancipatory essence. From Marx to Benjamin, critical philosophers who showed fidelity to the cause were denied a career in European universities and made impoverished, stateless, and homeless. Marginalization and critical theory are inseparable; yet, today, Marxism is institutionalized, and the Frankfurt School's Critical Theory is gentrified. Critical Theory from the Margins, however, revives the Critical Theory that endorses criticism, aiming to negate dominant regimes of truth. It is unapologetic in its fidelity to the universalist struggles of the minoritized. In that spirit, Saladdin Ahmed shows that capitalism imposes a totalitarian social mode of existence and neoliberalism perpetuates fascism as a class of ideology across nationalist and religious movements. This book, then, is both a theorization and an argument in favor of the application of the episteme of the silenced as the essence of the critical education necessary for achieving universal emancipation.
