Aristotle on Hate And Anger

'How do hate and anger differ? And is hate always the wrong response?' by Gregory B. Sadler, Ph.D..

"Anger is connected with hatred in Aristotle’s view, not least because, along with spitefulness and condemnatory talk (diabole), anger is one of the main causes of hatred. As many other moral theorists note — particularly after the sharpening of perspectives on love and hate brought by Christianity — when anger is nourished, held onto, repressed, even indulged for an extended period of time, it tends to congeal and cool into the less immediate, more enduring affect of hatred."
