This quote makes it seem like there is a very fine line between modernism and post-modernism. Modernist works like Kaprow's "happenings" acquired meaning with viewer participation, just like this quote is describing about postmodernism. Did the dual audience/artist role from Kaprow's "Happenings" inspire post-modernist artists?
