Reason, logic, and a demand for evidence are the boundaries that limit our capacity to assert, without cause, anything we wish. Irrationality removes such limits, and this is why religious belief is a profoundly destabilizing act. Truth itself loses its meaning when thought invokes the supernatural, and a mind without rational limits is so free that it actually becomes imprisoned by its own gullibility. Religious faith, with its outlandish claims to absolute Truth and Morality, is inherently conflict-ridden because its claims are exclusive. Religious faith is thus responsible for divisions between nations, within societies, and inside individual families. For ages, people have been arguing, fighting, killing, and dying over differing interpretations of nonsensical fairy tales. The magnitude of such tragedy is difficult to describe. At this stage of human history, primitivism is quickly merging with technological advancement and globalization to produce an existential threat to our civilization. It is therefore critical we examine our religious beliefs with honesty and openness. The Dark Side of Faith offers just such an incisive analysis of our most deeply-held assumptions.
