This Article examines the strengths and weaknesses of modern pacifist religious philosophy. The Article suggests that some intellectual arguments for pacifism are logically solid (once certain premises are granted), while others have serious flaws. The article discusses five influential philosophical advocates of non-violence Thomas Merton, Stanley Hauerwas, Leo Tolstoy, Tony Campolo, and John Howard Yoder. In addition, the Article examines three real-world cases where the practice of non-violence was put into action: the Danish rescue of the Jews during WW II, the American Civil Rights movement in the South in the 1960s, and the invasion of the Chatham Islands—the home of the pacifist Moriori tribes.
