text: I wrote this review because I felt that none of the reviews so far really got the main cause of this book. This is NOT a book about cosmology (as people would expect from Roger Penrose). In this tiny book, Penrose summarizes his idea that the mind cannot be understood by mathematical processes (something much different from the opinion of 99,99% of neurobiologists, such as Steven Pinker). This view is near to the Nobel laureate Murray Gell-Mann. The book is easy to understand and the ideas are very concise and its recommended for the ones that are interested in intelligence theories (thus, the author assumes that the reader know what a neuron is and how it works!). Some may think this is a difficult to understand book because they didn't had in mind that this book is about Penrose's point of view on intelligence. In fact, I'm not a physicist, nor a biologist, simply a high school student and I found the book very easy to understand, although I do not agree with Penrose's point of view. I think he forgot something very important. Read it and read the other point of view and you'll find what it is! :
