"Barr's dialectical vision of modern art remains instructive for early twenty-first-century students of contemporary art history. Barr understood the time frame of modern art to include both the present and the distant past, especially as the latter was rediscovered and reimagined in the current moment. In 2009, the art historian Miwon Kwon offered a similarly expansive view of contemporary art as that which is ""presumed to embody the newness of the present"" but can also ""engage prehistoric artifacts, revive ancient techniques or materials, and invest in outmoded images, ideas, and methods. That is to say, contemporary art may be of the present but can newly mobilize the past.""
