This book is for people who have a genuine interest in understanding nature. The book shows that matter has many structures. The most striking structure of all, one that is capable of creating information, is the living being. Information is the meaning that a living being gives to its surroundings, and in some cases, the explanation given to what does not exist. Life is a material process with an essential sub-process: informational ability. With informational ability, the structure of life can self-replicate and restructure to maintain its informational ability. The structure of life includes humanity, which today is at a crossroads. Matter interactions undeniably dominate reality and information dominates nature. We need to refine our informational ability to become better leaders and citizens; this is crucial in creating and maintaining a better world.
