Jungian psychologist Hollis turns the whole why-bad-things-happen-to-good-people question around and asks, instead, why good people often do such horrible things. Exploring the notion of the Shadow, Jung's term to describe the hidden aspects of ourselves--the parts that contradict the self we show the rest of the world, the dark side of our personality--Hollis suggests that we can only become whole (and good) by acknowledging our Shadow and accepting that it's OK to have a dark side, as long as we never let it take control of who we are. The prose is a little stodgy, and some readers might find the book feels a little too similar to others in the psychological self-help genre, but finally the similarities are only superficial. The difference between this book and most of the slick self-helpers is that Hollis has some genuinely important, meaningful things to say. A thoughtful book, well worth the concentration involved in reading it.
