Is it possible that kindness and cruelty aren’t opposites, but points along the same spectrum of human nature? Neuroscientist Abigail Marsh has spent decades studying what she calls the “caring continuum:” A range that runs from extreme altruists to individuals with psychopathy who feel little or no concern for others. Marsh challenges the widespread belief that humans are fundamentally selfish, showing instead how neuroscience, psychology, and everyday observation tell a more complex story.
