Religions evolve, not metaphorically, but in a very real way. By applying survival-of-the-fittest principles to religion, we can finally understand how religion became incredibly infectious to the average human.

The Religion Virus will show you how infectious ideas like the loving father-figure God, the promise that death is not the end, the attraction of heaven, the threat of hell, and many others evolved from prehistoric to modern times. You will finally understand why today's religions survived while thousands of other religions and sects died out. Like biological life, over ninety-nine percenty of the world's religions are extinct, but the ones that remain are quite remarkable. They are the strongest and best. More importantly, "survival of the fittest" does not necessarily mean survival of the truth, but rather the survival of the things people want to believe, whether true or not.

  • Why do you worship Abraham's God instead of Zeus, Pelé or Thor?
  • Why is a single all-purpose god far better than a bunch of special-purpose gods?
  • Why is religion necessarily hostile to science?
  • Why can't polytheism compete with monotheism?
  • Why do heaven and hell have to co-exist?
  • Why is "shunning" (casting out non-believers) so critical to religion's survival?

Dan Barker, author of Godless:
"Ingenious ... Craig James has cracked open the mystery of religion's tenacity. What Guns, Germs and Steel did for anthropology, The Religion Virus does for faith. It puts the pieces together into a fascinating, coherent model that makes sense!"
Dan Barker, author of Godless: How an Evangelical Preacher Became One of America's Leading Atheists, and co-president of the Freedom From Religion Foundation.
Secular News Daily:

New Consciousness Review:
"The Religion Virus will open your mind, offering a perspective on religion and social evolution that few have presented, and none with such delightfully reasoned enthusiasm and varying analogies. ... This book will keep you awake and engaged. I learned something new on so many levels that it was truly enjoyable and informative reading, and the ideas presented reverberated in my mind for days after each chapter. So much so, that as I sat down to write this review, I decided to read it all over again, just for the sheer joy of it."
– Julie Clayton, New Consciousness Review
Phil Steel:
"This is the most fun I've had reading non-fiction in a long time!" Review:
"[A] fascinating read ... an easy recommendation to anyone curious as to how religion has survived and what makes it so difficult to shake ... tolerant people of all walks have something to gain from checking it out." review Review:
"This book ... just sort of changes you, in a good way, to a new, deeper understanding of all the stuff we were taught as gospel. Read it, I guarantee you'll be glad you did, and you'll never think of religion the same way again."
