Some of the greatest achievements of science have come through that same type of foolishness. When an explanation is given of something and everyone in the world believes it, there may be one person somewhere who can't quite accept it; who instinctively says, "I'm not sure that this is sufficient explanation, there may be something beyond this." It's that kind of foolishness, Marie.
