Many modernists believed that art represented a pure realm outside existence and that the history of art followed a coherent, progressive trajectory culminating in modernism and abstraction. To most of the artists who followed them, by contrast, the concepts of artistic purity and the mainstream seemed naive. Cdritics and artists recognized that they lived in the midst of artistic pluralism, the presenced of a variety of artistic intentions and styhles. The generation that grew to maturity around 1970 had been the first to accept pluralism in its own right as a manifestation of our culturally heterogeneous age.
