Martha Nussbaum, "What Is Anger, and Why Should We Care?"

"Although everyone is familiar with the damage anger can do in both personal and public life, people tend to think that it is necessary for the pursuit of justice.  People who don't get angry when they are wronged seem weird to many people, lacking spine and self-respect.  And isn't it servile not to react with anger to great injustice, whether toward oneself or toward others?  On the other hand, recent years have seen three noble and successful freedom movements conducted in a spirit of non-anger: those of Mohandas Gandhi, Martin Luther King, Jr., and Nelson Mandela -- surely people who stood up for their self-respect and that of others, and who did not acquiesce in injustice.
