QUOTE : As I argue throughout this book, our mistakes disturb us in part because they call into question not just our confidence in a single belief, but our confidence in the entire act of believing. When we come to see one of our own past beliefs as false, we also glimpse, for a moment, the persistent structural possibility of error: our minds, the world, the gap between them—the whole unsettling shebang. As important and life-altering (and even gratifying) as this revelation can be, it runs contrary to what I’ve described here as one of the chief functions of a community: to buttress our sense that we are right, and protect us from constantly contending with the possibility that we are wrong. Small wonder that such revelations are so unwelcome within communities of believers, and bring down so much trouble on the individual member who abandons his or her faith. When we realize that we were wrong about a private belief, the chief thing we stand to lose is our pride. But when we share a belief with others, the stakes of rejecting it escalate astronomically. They include, as we’ve seen, the practical and emotional advantages of conforming with a community. But they also include the community itself—the trust, esteem, companionship, and love of the people we know best. Even more gravely, they include the stability and familiarity of our identities (for instance, as a devout Muslim), and our faith in the very existence of truth. Short of life and limb (which are occasionally on the line as well), the price of being wrong could scarcely be higher, and the experience could scarcely be more destabilizing.
