 In his last book The Aesthetic Dimension (1978), Marcuse continues his attempt to rescue the radical transformative nature of art. In this text he takes a polemical stance against the problematic interpretation of the function of art by orthodox Marxists. These Marxists claimed that only proletarian art could be revolutionary. Marcuse attempts to establish the revolutionary potential of all art by establishing the autonomy of authentic art. Marcuse states: “It seems that art as art expresses a truth, an experience, a necessity which, although not in the domain of radical praxis, are nevertheless essential components of revolution” (Marcuse 1978: 1). It is the experience that art tries to express that Marcuse will focus on and it is this which separates him from orthodox Marxists.
