Amateur: A True Story About What Makes a Man by Thomas Page McBee

"...I had been reading Carl Jung, who, after World War II, long consumed by the question of what made people evil, or complicit in evil, settled on a single, elegant explanation. He believed that ostracizing any aspect of the human experience, however ugly, created a "shadow" of our rejected bits that we drag behind us. If we do not see that the shadow belongs to us, we project it onto others, both individually and as a culture. To face and own what most disturbs you about yourself, Jung believed, is the among the central moral tasks of being human."
