We have reached a point, says Dallas Willard, where doubting is considered smarter than belief. Furthermore, we have severed responsibility from disbelief. According to Dr. Willard, this is morally reprehensible. Just as a doctor is responsible for making herself aware of new potential treatments for her patients, individuals have a responsibility to assume the burden of proof for their disbelief. Drawing on teachings about the nature of belief and disbelief, rationality, truth, and responsibility, Dr. Willard makes a strong case that disbelief is not a stance to be taken lightly.
