Everyone has a Shadow -- the hidden aspects of the Self which we hide from others and ourselves. . . but not only individuals, also groups have a collective Shadow, which if unrecognized and undealth with, can lead to problems such as scapegoating, racism, and wars.
This book presents an overview of the dark side of human nature as it appears in the self, in families, and groups such as countries, religions, etc; and suggests productive ways of dealing with the Shadow -- both individually and collectively.
