How is it that good people do bad things? Why is our personal story, our societal history so bloody, so repetitive, so injurious to self and others, so self-defeating? This book operates from a central thesis that is relatively unknown to the general public but is a truism for depth psychology, namely, that the human psyche is not a single, unitary, or unified thing, as the ego wants us to believe. It is diverse, multiplicitous, and divided... always divided.
