“Once a person believes - really believes - that certain ideas can lead to eternal happiness, or to its antithesis, he cannot tolerate the possibility that the people he loves might be led astray by the blandishments of unbelievers. Certainty about the next life is simply incompatible with tolerance in this one.”

“Most moral relativists believe that tolerance of cultural diversity is better, in some important sense, than outright bigotry. This may be perfectly reasonable, of course, but it amounts to an overarching claim about how all human beings should live. Moral relativism, when used as a rationale for tolerance of diversity, is self-contradictory.”

“What one believes happens after death dictates much of what one believes about life, and this is why faith-based religion, in presuming to fill in the blanks in our knowledge of the hereafter, does such heavy lifting for those who fall under its power. A single proposition – you will not die – once believed, determines a response to life that would be otherwise unthinkable.”

“When the stakes are this high- when calling God by the right name can make the difference between eternal happiness and eternal suffering, it is impossible to respect the beliefs of others who don't believe as you do.”

“Given the link between belief and action, it is clear that we can no more tolerate a diversity of religious beliefs than a diversity of beliefs about epidemiology and basic hygiene.”

“It is time we realize that belief is not a private matter. As a man believes, so he will act. Believe that you are a member of a chosen people, awash in the salacious exports of an evil culture that is turning your children away from God, believe that you will be rewarded with an eternity of unimaginable delights by dealing death to these infidels—and flying a plane into a building is only a matter of being asked to do it.”

“In the year 2006, a person can have sufficient intellectual and material resources to build a nuclear bomb and still believe that he will get seventy-two virgins in Paradise.”
