A groundbreaking and challenging examination of the social, cognitive, neurological, and biological roots of psychopathy, cruelty, and evil Borderline personality disorder, autism, narcissism, psychosis: All of these syndromes have one thing in common--lack of empathy. In some cases, this absence can be dangerous, but in others it can simply mean a different way of seeing the world.In The Science of Evil Simon Baron-Cohen, an award-winning British researcher who has investigated psychology and autism for decades, develops a new brain-based theory of human cruelty. A true psychologist, however, he examines social and environmental factors that can erode empathy, including neglect and abuse. Based largely on Baron-Cohen's own research, The Science of Evil will change the way we understand and treat human cruelty.

A brave mouse, a covetous rat, a wishful serving girl, and a princess named Pea come together in Kate DiCamillo's Newbery Medal–winning tale.

As Kate DiCamillo would say: Reader, it is your destiny to find out. With black-and-white illustrations and a refreshed cover by Timothy Basil Ering.
