" The form of a myth is indeed externally conditioned by facts. There is a minimum of evidence with which it must comply if it is to live, but once lip service has been paid to that undeniable minimum, the human mind is free to indulge its infinite capacity for self-deception. When we consider upon what ludicrous evidence the most preposterous beliefs have been easily and by millions entertained, we may well hesitate before pronouncing anything incredible. "
