This week, Humanist Canada's Daniel Dacombe interviews social psychologist and author Dr. WIll Gervais. Dr. Gervais recently published his first book: 'Disbelief - The Origins of Atheism in a Religious Species,' and was gracious enough to sit down and talk about it with us. Based on years of research, Disbelief is a compelling and evidence-based look at how human beings came to be religious, and how some of us came to be secular.
