What is contemporary art? What defines its contemporaneity? And in which sense can it be called art when it defies categories of modernist art theory? How to define the plural of art when the old art genres have dissolved into countless hybrid forms? And what follows from the artistic destabilization of the border between art and non-art? What are the aesthetic and political implications of an art that addresses its audience and its institutional frameworks as well as questions of globalization, digitalization, historiography, and nature? The seminar will discuss these problems by looking at philosophy, art criticism, and artist writings.
