“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.”

“In adaptive terms, belief has been extraordinarily useful. It is, after all, by believing various propositions about the world that we predict events and consider the likely consequences of our actions. Beliefs are principles of action: whatever they may be at the level of the brain, they are processes by which our understanding (and misunderstanding) of the world is represented and made available to guide our behavior.”

“When considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't. Religion is one area of our lives where people imagine that some other standard of intellectual integrity applies.”

“As we have seen, there is something that most Americans share with Osama bin Laden, the nineteen hijackers, and much of the Muslim world. We, too, cherish the idea that certain fantastic propositions can be believed without evidence. Such heroic acts of credulity are thought not only acceptable but redeeming ― even necessary.”

“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.”

“Faith does not offer a strong link between our beliefs and actual states of the world.”

“If someone doesn't value evidence, what evidence are you going to provide to prove that they should value it? If someone doesn’t value logic, what logical argument could you provide to show the importance of logic?”
