These provocative questions lie at the heart of How We Believe, an illuminating study of God, faith, and religion. Best-selling author Michael Shermer offers fresh and often startling insights into age-old questions, including how and why humans put their faith in a higher power, even in the face of scientific skepticism. Shermer has updated the book to explore the latest research and theories of psychiatrists, neuroscientists, epidemiologists, and philosophers, as well as the role of faith in our increasingly diverse modern world. Whether believers or nonbelievers, we are all driven by the need to understand the universe and our place in it. How We Believe is a brilliant scientific tour of this ancient and mysterious desire.
