Society, in fact, often holds it to be a virtue to adhere to certain beliefs in spite of evidence to the contrary. Belief in that which reason denies is associated with steadfastness and courage, while skepticism is often identified with cynicism and weak character. The more persuasive the evidence against a belief, the more virtuous it is deemed to persist in it. We honor faith. Faith can be a positive force, enabling people to persevere in the face of daunting odds, but the line between perseverance and fanaticism is perilously thin. Carried to extremes, faith becomes destructive—the residents of Jonestown for example, or the Heaven’s Gate cult. In both cases, the faith of the believers was tested; in both cases, they passed the test.
