The book by V. Vedral, Decoding Reality: the Universe as Quantum Information, deals with one of the most interesting aspects of modern scientific research, the conceptual status and the role of information in understanding reality. The quantum revolution, which has required a radical change of our views of natural processes has also implied a basic revision of the way in which we look at information. In this sense, the subject of the book is surely relevant and timely. Some of the topics discussed by the author are stimulating and are presented in a readable and pleasant way. I have in mind, e.g. the analysis of the way in which the genetic information is preserved and transmitted as well as the description of how quantum mechanics allows an absolutely unbreakable way of secret communication. However, the real target of the book is by no means the one of making accessible to non experts the present status of the subject, the book is much more ambitious, as one can guess already from its title: Decoding Reality. Actually, its very first pages make fully clear that the aim of the author is to make understandable and compelling even for the layman (by concisely reviewing the revolutionary aspects of quantum mechanics) the fundamental fact that the informational viewpoint yields a simple solution to the most basic and challenging quests of human beings, i.e., those of understanding their origin and the one of all other things around them. It is precisely for this reason that the author feels the need to analyze various basic religious and philosophical questions. Taking into account the just mentioned intended real purpose of the book, which is made quite explicit by the author, I feel the need to present various critical remarks. In order to avoid any misunderstanding a premise is appropriate.
