Kwame Anthony Appiah, philosophy professor at Princeton University, argues that “moral revolutions,” from the demise of duels to solve personal arguments in Britain to the end of foot binding in China, succeed when a population’s traditions come into dispute with the idea of the honor of the country. The author contends that social movements are dependent upon shifting focus to a code of honor that puts into question why certain acts were considered “honorable” in the first place and how an examination of history and passage of time can bring a successful end to certain long held acts and traditions. Kwame Anthony Appiah discussed his book at the Harvard Book Store in Cambridge, Massachusetts. Topics included current campaigns against the “honor killing” of women.
