The author states that this book is for anyone seeking a deep and systematic explanation of life, and I think this was a fair statement. Every page of this book pours out information of a thought provoking nature. It has the unusual ability to contain a complexity of thought which is coupled with a simplicity of expression. The arguments are provocative and insightful and so well presented that the profundity of what is being revealed usually comes across as basic common sense, yet much of what I was reading was new to me. The author has a way of cutting through the chaos and complexity of life to reveal a simple symmetry. This is well worth a read - every chapter contains a depth of thought that will give you plenty to think about for a long time to come.
