As a correspondent for The New York Times - and other publications - activist and ordained Presbyterian Minister Christopher Hedges has covered wars all over the world. In 2002, he shared a Pulitzer Prize for his work on global terrorism. The author of 14 books, he's no stranger to controversy, having once been escorted off stage while delivering a commencement address. In the fall of 2014, Christopher Hedges gave a lecture at Ryerson University in Toronto, and later joined Paul Kennedy in conversation.

The presentation Chris Hedges gave at Ryerson University is titled War is a Force That Gives Us Meaning.
