People of the Lie by Scott Peck

This is an insightful and groundbreaking study of evil, used by Cynthia in her Wisdom Schools on Evil, but has some challenging and problematic aspects.

People who are evil attack others instead of facing their own failures. Peck demonstrates the havoc these people of the lie work in the lives of those around them. He presents, from vivid incidents encountered in his psychiatric practice, examples of evil in everyday life.

This book is by turns disturbing, fascinating, and altogether impossible to put down as it offers a strikingly original approach to the age-old problem of human evil.
