We know that accidents happen, but we believe we are on earth for a reason. Until now, most scientists have argued that science and faith occupy distinct arenas. Francis Collins, a former atheist as a science student who converted to faith as he became a doctor, is about to change that. Collins's faith in God has been confirmed and enhanced by the revolutionary discoveries in biology that he has helped to oversee. He has absorbed the arguments for atheism of many scientists and pundits, and he can refute them. Darwinian evolution occurs, yet, as he explains, it cannot fully explain human nature - evolution can and must be directed by God. He offers an inspiring tour of the human genome to show the miraculous nature of God's instruction book.

    All the advances of modern life--the medical breakthroughs, the public health institutions, the rising standards of living--have given us each about twenty thousand extra days on average. There are few measures of human progress more astonishing than our increased longevity.This book is Steven Johnson's attempt to understand where that progress came from. How many of those extra twenty thousand days came from vaccines, or the decrease in famines, or seatbelts? What are the forces that now keep us alive longer? Behind each breakthrough lies an inspiring story of cooperative innovation, of brilliant thinkers bolstered by strong systems of public support and collaborative networks.But it is not enough simply to remind ourselves that progress is possible. How do we avoid decreases in life expectancy as our public health systems face unprecedented challenges? What current technologies or interventions that could reduce the impact of future crises are we somehow ignoring?

    Simply put, beliefs come first and explanations for beliefs follow. The brain, Shermer argues, is a belief engine. From sensory data flowing in through the senses, the brain naturally begins to look for and find patterns, and then infuses those patterns with meaning. Our brains connect the dots of our world into meaningful patterns that explain why things happen, and these patterns become beliefs. Once beliefs are formed the brain begins to look for and find confirmatory evidence in support of those beliefs, which accelerates the process of reinforcing them, and round and round the process goes in a positive-feedback loop of belief confirmation. Shermer outlines the numerous cognitive tools our brains engage to reinforce our beliefs as truths.Interlaced with his theory of belief, Shermer provides countless real-world examples of how this process operates, from politics, economics, and religion to conspiracy theories, the supernatural, and the paranormal. Ultimately, he demonstrates why science is the best tool ever devised to determine whether or not a belief matches reality.
