Many of the ideas central to the understanding of contemporary art - genre, fragment, project, the new or, the concepts of art and criticism themselves - derive from early German Romanticism. This lecture revisits Friedrch Schlegel's Athenaeum Fragments, one of the defining documents of the early German Romanticism, as the basis for a new interpretation of Sol LeWit's Sentences on Conceptual Art, focusing in particular on the issues of the art-status of criticism and its philosophical function of 'completing' works of art.
