“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.”

“Believing a given proposition is a matter of believing that it faithfully represents some state of the world, and this fact yields some immediate insights into the standards by which our beliefs should function. In particular, it reveals why we cannot help but value evidence and demand that propositions about the world logically cohere.”

“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.”

“Are you really surprised by the endurance of religion? What ideology is likely to be more durable than one that conforms, at every turn, to our powers of wishful thinking? Hope is easy; knowledge is hard. Science is the one domain in which we human beings make a truly heroic effort to counter our innate biases and wishful thinking. Science is the one endeavor in which we have developed a refined methodology for separating what a person hopes is true from what he has good reason to believe. The methodology isn't perfect, and the history of science is riddled with abject failures of scientific objectivity. But that is just the point-these have been failures of science, discovered and corrected by-what, religion? No, by good science.”

“The problem with religion, because it's been sheltered from criticism, is that it allows people to believe en masse what only idiots or lunatics could believe in isolation.”

“While believing strongly, without evidence, is considered a mark of madness or stupidity in any other area of our lives, faith in God still holds immense prestige in our society. Religion is the one area of our discourse where it is considered noble to pretend to be certain about things no human being could possibly be certain about. It is telling that this aura of nobility extends only to those faiths that still have many subscribers. Anyone caught worshipping Poseidon, even at sea, will be thought insane.”

“Where we have reasons for what we believe, we have no need of faith; where we have no reasons, we have lost both our connection to the world and to one another.”
