Abstract
I situate Adorno's 1931 inaugural lecture in the context of German philosophy in the 1920s. The crisis of idealism in the early twentieth century is explained in terms of the new emphasis in capitalist society on the role of impersonal, scientific knowledge. I demonstrate that Adorno, in the lecture, rejects the neo‐Kantian goal of aligning philosophy with the new scientific culture, but also dismisses the positivist idea of dissolving philosophy into natural science, as well as the irrationalist currents such as life philosophy and existentialism. Adorno's lecture argues instead for a version of dialectical philosophy that is rooted in the practices and techniques of early aesthetic modernism.
