Book excerpt: Art has been an umbrella term for poetry; music, dance, sculpture painting, and architecture since the end of the eighteenth century, when the bourgeoisie were establishing their hegemony over culture and politics in Germany, labor was becoming more clearly divided, and religion was losing its unifying force. Art became a broad and separate entity as the expectations and experience of it changed. The Institutions of Art concentrates on German and French literature in illustrating the formation of aesthetic autonomy and the divergence between high and popular culture. Peter B_rger builds on his earlier Theory of the Avant-Garde (1984), pushing further into key theoretical questions about art and society. Christa B_rger extends the critique to the history of the novel, focusing on Goethe and Kleist. Looking backward to feudalism and forward to our century, the authors show how the function of art has changed along with the criteria for its production and evaluation.
