The Aesthetic Dimension: Toward a Critique of Marxist Aesthetics (German: Die Permanenz der Kunst: Wider eine bestimmte marxistische Ästhetik) is a 1977 book on aesthetics by philosopher Herbert Marcuse, in which Marcuse provides an account of modern art's political implications and relationship with society at large. It is the final major work by Marcuse, a founding member of the Frankfurt School. The book is also noteworthy as a demarcation of Marcuse's split with Marxism via his rejection of Marxist aesthetics.
