"This constraint upon our thinking has always been a problem for religion. Being stocked stem to stern with incredible ideas, the world’s religions have had to find some way to circumvent reason, without repudiating it. The recommended maneuver is generally called “faith,” and it actually appears to work. Faith enables a person to fool himself into thinking that he is maintaining his standards of reasonableness, while forsaking them. There is a powerful incentive to not notice that one is engaged in this subterfuge, of course, because to notice it is to fail at it. As is well known, such cognitive gymnastics can be greatly facilitated by the presence of others, similarly engaged. Sometimes, it takes a village to lie to oneself."
