Poems, sonnets, entire tomes have been written about pure love. Less ink has been spilled on pure hate. Berit Brogaard, Professor of Philosophy and Director of the Brogaard Lab at the University of Miami, joins host Krys Boyd to talk about the morality, psychology, science, and justifications for an emotion all of us feel, but no one likes to own up to. She’s the author of “Hatred: Understanding our Most Dangerous Emotion.”
