This volume of lectures on aesthetics, given by Adorno in the winter semester of 1958-9, formed the foundation for his later Aesthetic Theory, widely regarded as one of his greatest works.  The lectures cover a wide range of topics, from an intense analysis of the work of Georg Lukács to a sustained reflection on the theory of aesthetic experience, from an examination of works by Plato, Kant, Hegel, Schopenhauer, Kierkegaard and Benjamin, to a discussion of the latest experiments of John Cage, attesting to the virtuosity and breadth of Adorno's engagement.  All the while, Adorno remains deeply connected to his surrounding context, offering us a window onto the artistic, intellectual and political confrontations that shaped life in post-war Germany.  This volume will appeal to a broad range of students and scholars in the humanities and social sciences, as well as anyone interested in the development of critical theory.
