Jonathan Schell spent a lifetime exploring war in all its various incarnations. His 1982 book, The Fate of the Earth – in which he called for complete nuclear disarmament -- was called “the new Bible of our time, the White Paper of our age,” by Helen Caldicott, president of Physicians for Social Responsibility. He had been a lead writer at The New Yorker till 1987, a columnist for Newsday and New York Newsday, and, most recently, a correspondent for The Nation. He died recently at the age of 70. You can hear his interview with Leonard from May 2003, when he spoke about the greatest non-violent moments in modern history, from his book The Unconquerable World.
