Hatred is often considered the opposite of love, but in many ways is much more complicated. It also may be considered one of the dominant emotions of our time, as individuals, groups, and even nations express or enact hatred to varying degrees. What is hatred? Where does it come from and what does it reveal about the hater? And is hatred always a bad thing?

Brogaard makes a deep dive into the moral psychology of one of our most complex, and vivid emotions. She explores how hatred arises between people and among groups. She also shows how hate, like anger, can sometimes be appropriate and fitting. Other questions she addresses are, how does hate differ from anger, disgust, fear, and other related emotions? Is fear an essential part of hatred? How does hatred affect what happens inside the brain? How did hate evolve in human history? Is hatred ever morally justified? Can you hate and love at the same time? Can one hate oneself? How do implicit biases trigger hatred of groups?
