The moral status of emotions has recently become the focus of various philosophical investigations. Certain emotions that have traditionally been considered as negative, such as envy, jealousy, pleasure-in-others'-misfortune, and pride, have been defended. Some traditionally "negative" emotions have even been declared to be moral emotions. In this brief paper, I suggest two basic criteria according to which an emotion might be considered moral, and I then examine whether envy, anger, and resentment are moral emotions.
