In this foundational work of critical theory, Herbert Marcuse presents a powerful critique of advanced industrial society. He argues that modern capitalism creates false needs, integrating individuals into a system of production and consumption that suppresses dissent. Through mass media and consumer culture, society becomes 'one-dimensional,' lacking the capacity for critical thought and opposition. Marcuse exposes the illusion of freedom in a seemingly tolerant society, revealing the subtle forms of social control that maintain the established order and prevent genuine social change.
