In Aesthetic Theory, Adorno argues that, in modernity, art and philosophy are reciprocally dependent upon each other for legitimation and critical force. This claim has puzzled scholars and provoked controversy. I argue that Adorno’s thesis may be comprehended in the following manner: art requires philosophy because, without the latter, art would lack the power to critique social and historical reality (in particular, the ideological elements that often remain invisible as second nature), and to rationally interpret the material particularity expressed by (...) such reality; and, conversely, philosophy requires art because the latter expresses historical experience to reason. Such material historical experience is necessary in order to prevent philosophy from falling into ideological convention; idle speculation; or abstract and reified instrumentality. Thus, the constellation of history, art, and philosophy is essential to Adorno’s aesthetics. (shrink)
