The Wisconsin Academy of Sciences, Arts and Letters will observe the 10th anniversary of the terrorist attacks of 9/11 on Sunday, September 11, 2011, with an afternoon of discussion and reflection. “Perspectives on a Post-9/11 World” brings together a diverse group of distinguished historians, political scientists, artists, musicians, and writers to reflect on questions surrounding who we have become as a nation and as a people in an age of global terrorism, liberation movements, technological upheavals, economic insecurity, and fractious politics. “Making Art, Making War” features John DeMain, music director of the Madison Symphony Orchestra and Wisconsin Academy Fellow; Jane Simon, curator at the Contemporary Art Museum at the University of South Florida (who until recently was curator of exhibitions at the Madison Museum of Contemporary Art); and Valerie Laken, assistant professor of English at UW–Milwaukee and author of “Separate Kingdoms: Stories” considering how the arts can provide new ways of understanding tragedy.
