This book addresses the fundamental question that humans have been concerned with throughout history: what are we and where do we come from and, more importantly, where are we going ... all these questions have to do with what is " reality". 
Tomás Morales, in this book, has discussed these basic questions from the perspective of what is real and what is made up in our own minds, which brings us to the last question: why are we here or what is the ultimate goal? in human life? 
Tomás Morales has approached this issue of what reality is from many aspects, including the spiritual and scientific basis used by others to explain human behavior. 
All these discussions make us wonder again who we are and where we are going ... this becomes a fundamental question in astronomy, now that we know, that the earth is just a kind of dust in the cosmos! Thomas has discussed this fundamental topic from his own life experiences and his deep understanding of the scientific and theological bases of human behavior, and I find this book to be a very deep look at human behavior!
