Most people look to religion and science (faith and reason) for an explanation of “everything that is,” but neither the scientific nor the religious system can actually provide all the answers to life's questions. Is that really what we're looking for? The author examines both science and religion in some detail and from a variety of standpoints. A life-long educator, he indicates many avenues for further reading, so that no one has to simply accept whatever his family or community traditions may have proposed. One sticking point in most discussions of religion vs. science is that few of us really have enough information about both positions - and the myriad hybrid beliefs in between - in order to make a proper evaluation. As a professor of medicine and an avid investigator of these questions, Dr. Guido Perez offers some background and guidance. The author explores the basics of theism and today's largest religions, and gives a solid grounding in the facts and theoretical basis for evolution and the scientific approach to knowledge. He then explores a possible place to stand in, both morally and intellectually grounded, while we puzzle out our existence: a rational belief system that accounts for what we can account for, while recognizing those mysteries and existential questions we humans just can't seem to stop asking. Dr. Perez proposes a rational belief system grounded in natural science and humanism, an approach where morality comes naturally - not because we fear divine punishment but because we inherently understand what is good for humanity.
