However, once I started reading it I finished it in one long sitting.
The concepts are simple and make sense.
The core concept is that every man has varying amounts of King (representing the ability to bring order out of chaos, and a sort of benevolent use of power), Warrior( the ability to marshal resources, have courage, bear pain, make clear choices based on facts not emotions), Magician (or "alchemist" - concerned with knowledge and skill, and how to use it), and Lover (emotionally connected to others, having empathy).
Each one of these attributes has many good qualities; they can turn negative however, in both active and passive ways. The book cogently explains the symptoms of this - this was the part of the book that made me think the authors knew what they were talking about, in that I saw myself and my co-workers in some of the examples.
