Revolutions historically have come in waves, and the world appears to be riding one now – from the Arab Spring to anti-austerity protests in Greece to the more recent Occupy movement. In a discussion of his new book, Pulitzer Prize-winning journalist Chris Hedges examines the social and psychological factors that foster rebellion. And he makes the case that environmental destruction and wealth polarization are planting the seeds of modern revolt in the U.S. and around the globe. Hedges, a senior fellow at the Nation Institute, columnist for the progressive website Truthdig, and former Middle East bureau chief for The New York Times, spoke at the Library in March 2011 about his book Death of the Liberal Class.
